The impact of Bus Rapid Transit service on the housing price : Accessibility and Proximity

Biography : 杨林川,现任西南交通大学建筑与设计学院城乡规划系研究员,香港大学博士、研究型硕士,厦门大学工学学士、理学学士。他的研究重点是交通与土地利用、交通经济、交通地理和交通行为。目前,已发表SCI/SSCI论文30余篇,刊物包括《Transportation Research Part A/D》《Sustainable Cities and Society》《Cities》《Journal of Transport Geography》和《Journal of Destination Marketing & Management》;担任19本SCI/SSCI期刊的特邀审稿人;在国际/国内学术会议上发表成果演讲10余次,担任会议分会场主持人3次;相关研究成果在2个全国性的智慧交通大数据应用创新大赛上获奖;入选西南交通大学2020年雏鹰学者。
Abstract : BRT兼具地铁和常规公交的优点----客运量大、运行速度快、建设成本低、灵活性高,在全球众多地区(尤其是南美洲城市和东亚城市)得到青睐。理论上,BRT对周边房价的影响有以下两个方面:(1)房屋靠近BRT站点,方便居民使用BRT服务,这使得站点可达性对房价存在正向影响;(2)临近BRT廊道可能会带来噪声、空气污染等问题,使得廊道临近性对房价存在负向影响。但是,现有实证研究主要关注BRT站点可达性对房价的正向影响,极少关注到BRT廊道临近性对房价可能产生的负向影响。另一方面,BRT对房屋价格的两方面影响可能在不同的价格分位数点和不同的空间而呈现差异。基于此,本文以厦门市离BRT廊道1.5km以内的房屋数据为样本,建立空间特征价格模型、分位数回归模型和地理加权回归模型进行分析。本文研究结论放下:(1)BRT对房价的正负影响效应显著存在;(2)BRT临近性对高价房的价格影响大于对低价房的影响;(3)房屋价格对房价的正负影响效应具有空间异质性;(4)BRT可达性对郊区房价的提升作用更大。本文的结论也说明忽视BRT廊道临近性影响会带来对BRT可达性影响的错误估计。

CAI Xiaolei, City University of Hong Kong

The Deep Sea Port and the Urban Fantasy of Anaklia

Biography : Cai Xiaolei currently is seeking his PhD of Architecture in City University of Hong Kong. His main research focus is the architectural and urban development in post-soviet states, and the construction under China’s foreign aid. He received his M. Arch from Oxford Brookes, and University College London. His personal research and professional experience includes urban planning and architecture design in various scale.
Abtract : Locating in the northwest of Georgia, Anaklia stayed relatively invisible in the past except its famous 8km coastline which made it a natural resort village. Since the 21st century, the strategic location and geographic conditions have drawn attentions. The coast of the Black Sea and the deep-water depth favoured the construction of a deep seaport, which is in urgent needs of Georgia since the ports of Batumi and Poti do not capable of supporting such project while Georgia seeks to become a transit hub. Encouraged by the Belt and Road Initiative (B&R), and the economic development request of Georgia, an American and Georgian jointed venture was entrusted by the government of Georgia in attracting investment, designing and implementing this Deep Sea Port project. Since the project’s initiation in 2016, the small resort became a platform for architectural showcase, and the urban environment has been drastically changed. Despite the project was in a suspension since January 2020, the anticipation of Anaklia becoming ‘A city of festival’ and ‘A city of the future’ has never stopped. Through detailed case study of the Deep Sea Port project and the urban development of Anaklia in both macro and micro scale, this research hopes to reveal what are the underlying reasons for this urban transport infrastructure, and what are the impacts that it brings to the urban development of Anaklia. Would the urban fantasy of Anaklia continue or would Anaklia become another collapsed ‘Lazika’ as it was in the past ?

Françoise MANDERSCHEID, Associate Professeur at Ecole des Ponts ParisTech

Urban and Railway transport studies throughout the world in an academic environment

Biography : Associate Professeur at Ecole des Ponts ParisTech, Member of board of Rail safety French Agency, 30 years of experience in the areas of railway engineering and staffing infrastructure project in SNCF and Systra, 5 years as HR manager in railway maintenance operational unit at SNCF, 15 years in railway educational and training programs in SNCF and ENPC, In-depth knowledge of educational engineering for railways programs.
Abstract : For nearly 10 years, as part of our post graduate program in urban and railway transport system engineering, the students have developed urban and railway transport studies with Agence Française de Developpement (AFD) or the World Bank. This program was created in 2008 by rail and transport major companies such as Alstom, Bombardier, SNCF, RATP to deal with railway expertise shortages.
Those feasibility studies address mass transit in megacities of developing countries such as Nigeria, Burundi, Ivory Cost, Bangladesh, Pakistan, Peru – mostly megacities with millions of inhabitants. They are similar to those performed in the design stage of project by international consultancies as ParsonsBrickerhof or Systra, and mainly focus on new transport infrastructures as strategic elements to cope with congestion and rapid urbanization.
I will present 2 projects : the first one is a suburban railway in Dhaka in Bengladesh (2019) and the second (2020) a cable car between Cotonou and Abomey-Calavi which is a district area.
The analysis and reports of the students is based on data compile through a large network of experts, embassies, financial institutions, online resources and of course their own resourcefulness… However, for this particular exercise they do not do any field work in the country.
To gather data socio-economic methods of assessment in large infrastructure projects are used. However, the students are often confronted to the lack of availability and access to data needed to assess the traffic forecast and passengers demand. In addition, a very deep analysis of geographic urbanism and socio-demographic data is done to choose the best routes or lines for the new transport system project proposed by the students.
After their presentation, all the jury members are usually very pleased to have visited or discovered a new town where they have never been before….

Abstract Hervé PHILIPPE


Comment les véhicules autonomes peuvent-ils aider les transports publics à augmenter leur part modale en banlieue après le COVID-19 ?/ Autonomous vehicles can improve the modal share of public transport

Carlos Holguin, Msc., est un urbaniste spécialisé dans l’intégration et le déploiement de véhicules entièrement automatisés dans les zones urbaines, et un concepteur de produits. Il a développé son expertise à travers l’expérimentation en conditions réelles de services de mobilité à la demande utilisant des véhicules automatisés depuis 2004, notamment dans les projets CityMobil (en tant que membre de l’INRIA) et CityMobil2 (en tant que membre de l’Université de Rome « La Sapienza »). Il a géré des projets de déploiement de véhicules automatisés dans plus de 15 villes à travers l’Europe, ainsi que le premier service de navette autonome au monde sur la voie publique, en 2011 à La Rochelle, en France. Actuellement, il dirige SuburVAN, une startup fournissant une solution de minivan autonome pour les banlieues.
Carlos Holguin, Msc., is an urban and mobility planner specialized in the integration and deployment of fully automated vehicles in urban areas, and a Product Designer. He developed his expertise through the real-life experimentation of on-demand mobility services using automated vehicles since 2004, in particular in the CityMobil (as member of INRIA) and CityMobil2 (as member of the University of Rome “La Sapienza”) projects. He has managed deployment projects with automated vehicles in over 15 cities across Europe, as well as the world’s first autonomous shuttle service in public roads, in 2011 in La Rochelle, France. Presently he’s leading SuburVAN, a startup providing an autonomous minivan solution for suburban commuters.
Abstract :How can autonomous vehicles help public transport increase its modal share in suburbs after the COVID-19 ?
The key indicator for public transport to compete against the private car is commercial speed. If, after the PANDEMIA and lockdown, suburban inhabitants rush to their cars, congestion will increase, reducing private cars’ commercial speed.
This will open a window of opportunity for public transport to expand to suburbs with a high-quality, high-frequency offer providing reliable travel-times, with the benefit of helping to compensate for the foreseeable loss of revenue from dense areas.
However, as we’ll see in this presentation, current autonomous vehicle technologies are not fully adapted to public transport operation in suburban areas.

YANG Hongtai, University of Tennessee at Knoxville, USA

How to define the optimal catchment area for subway stations ? A study of five cities in the U.S.

Biography : Hongtai Yang received the Ph.D. degree in transportation engineering and M.S. degree in statistics from The University of Tennessee at Knoxville, USA. He is currently an Associate Professor in the School of Transportation and Logistics, Southwest Jiaotong University, Chengdu, China. His research has been funded by various foundations and agencies, including National Natural Science Foundation of China and China Postdoctoral Science Foundation. He has received the China Intelligent Transportation Association Science and Technology Award and obtained the First Place in the Teaching Contest of Southwest Jiaotong University. His research area includes travel behaviour, GIS-T, transportation safety, and flexible transit planning. He likes salsa dancing and hates cooking.
Abstract : Direct demand modeling is a useful tool to estimate the the demand of a subway station and to determine factors that significantly influence the demand. The construction of the direct demand model involves the determination of the catchment area. Although 800 meters are usually used, whether this distance could well represent the catchment area is not well studied. This paper investigates the subway station’s optimal catchment areas using data of five cities in America as an example. We define five catchment areas by drawing buffers around each station with radius ranging from 300 to 1500 meters with the interval of 300 meters. Built environment characteristics within each catchment area are extracted as explanatory variables. Annual average weekday ridership of each station is used as the response variable. Three commonly used regression models, linear regression, linear regression with log-transformation and negative binomial regressions, are applied to examine which catchment area has the highest goodness-of-fit. The effect of distance decay is also considered by applying lower weight to outer catchment area. We find that the result of different catchment areas are comparable. Considering the effect of distance decay could barely improve the model results. When the catchment areas are overlapping, dividing the overlapping area by the number of times of overlapping could improve model results. The goodness of fit of the three models are comparable, though the linear regression with log-transformation has the highest prediction accuracy. This study could provide useful reference to researchers and planners on how to select catchment area when constructing direct demand models for subway stations.

Le projet de réseau express vélo, RER-V, en région Ile de France/ The express bike network project, RER-V, for Paris Region

Dominique RIOU est ingénieur transport à l’Institut Paris Region. 25 ans d’expérience lui ont donné une grande connaissance sur l’ensemble des problématiques urbanisme-transport-mobilité.
Résumé : 20 km/h c’est la vitesse moyenne que peut atteindre un cycliste urbain, sans effort exceptionnel, grâce à une infrastructure cyclable de qualité. C’est l’objectif du projet RER-V et ainsi faire du vélo un mode de premier plan dans la mobilité urbaine.

Dominique Riou is project manager at L’Institut Paris Region, the Paris/Ile-de-France Regional planning Agency, in the transportation and mobility department. He has been involved in many regional planning projects. He notably wrote and compiled the transportation chapter of the new master plan of the Paris Region. He took part in the elaboration of the travel plan of the Paris Region.
His competency on regional planning issues has also been developed through his involvement in many international projects (Casablanca, Tangier, Tetouan, Beirut, Hanoi, Erevan, Damas, etc) by being in charge of transportation issues. He worked on preliminary studies of the tram project of Bordeaux. He led many studies concerning transport systems, modes and infrastructures.
He is especially involved in active modes and public spaces sharing issues. He strongly takes part in the « Réseau Express Régional Vélo / RER V » project.
Dominique Riou has a degree in civil engineering (National Institute of Applied Sciences of Lyon, 1992) and a Master in Urban Planning (University of Lyon II, 1993).
Abstract : 20 km/h is the average speed for an urban biker, without exceptional effort, thanks to an efficient cycling infrastructure. That’s the goal of the RER-V project and thus make cycling a leading mode of transport in the urban mobility.
In the Paris Region, there are already 5800 km of the road network that can be considered as cycling, especially 1860 km of dedicated cycling ways. Those are a powerful foundation for quick routes, secure and identified, particularly useful to connect people to employment sites and to reinforce the links between the heart of metropolis and its outskirts. A cycling network with a high quality of service, will make biking a powerful mode of transport for both metropolitan and local territories.
In order to fulfil these objectives, the project of the « Réseau Express Régional Vélo RER V » has been initiated to connect the main urban poles with cycling ways across the region and to offer, on the model of public transport, a new alternative to some of the users of cars or public transport. The project led by the Paris Region - Région Ile-de-France - has been worked out with the technical help of L’Institut Paris Region. The President of the Region, Mrs Valérie Pécresse, has announced she would massively support it, up to 300 million euros.

Abstract : An important evolution in the automotive industry takes place with the development of intelligent vehicles. Manufacturers are trying to minimize the use of cables as much as possible to pass completely to a wireless communication system in those vehicles. Reducing the number of wires will provide simpler maintenance process and avoid wires detachment near rotating devices. One of the main limitations for communicating in solid channels is that the electromagnetic waves could not propagate in such mediums due to Faraday shielding. Also, the emission of those waves may require high power which is unlikely in the automotive industry. Therefore, the need of an alternative wave is required to solve those problems. The use of guided waves such as Lamb waves for communication in solid media may be a promising solution. Indeed, these waves can propagate over long distances. The objective of this work is to develop a high-speed communication system in healthy and damaged aluminum plates based on the concept of cross-correlation, able to compensate dispersion, damage presence, reverberation and multiple reflections in the transmission channel for smart vehicles application. For this sake, a series of experiments using a platform for ultrasonic communication using guided waves were carried out. These tests were held on a healthy plate at first using amplitude and phase modulation techniques and in the presence of different damages thereafter. Results show that reliable communication with high speed can be achieved even in the presence of severe damage to the transmission channel.

abstract : In metropolises, especially megacities, railways with large train units operated at high frequency constitute the most massive mode of passenger transportation. In Paris, line A of RER : Regional Express Railways, accommodates up to 30 trains per hour and per direction at peak periods on working days, each train with nominal capacity of 2,800 passengers (and often more people in it). Such massive flows entail proportional pedestrian flows on station platforms.
A station platform fulfills two functions of, first, passenger flowing and, second, passenger storage. The platform layout is initially designed and then adapter to enable for safe traffic and sufficient fluidity, with special attention to emergency situations and evacuation procedures.
Our aim is to provide a systemic analysis of a station platform as a traffic system which involves two types of mobile entities, namely pedestrians (users) and vehicles (trains), each one with specific conditions, behaviors and circumstances. The respective entity dynamics and their interactions are described in a structured way. We shall feature out the traffic system structure in terms of components and relations. Sub-systems are identified. Systemic diagrams will be provided to summarize the system’s anatomy and physiology.
After a general introduction, the communication will address in turn each of the following sub-systems : (i) the platform layout, (ii) the spatial structure of pedestrian flows, (iii) the dynamics of train traffic and platform pedestrian traffic in interaction. Lastly, we assess the modeling ability of a selected set of traffic simulation models.

Abstract : In the first part, we provided a systems analysis of pedestrian traffic along a railway station platform in relation to train traffic in terms of station arrival and departure times as well as on-board passenger loads. The longitudinal dimension of the platform is especially important since it is associated to (i) platform layout in relation to access points, (ii) passenger positioning for waiting, in relation to the rest of their trips and especially their on-board conditions and their stations of alighting, (iii) train on-board flows taking into account previous boardings and alightings, local alightings and boardings, these in relation with platform flows as well as with passenger behaviors (boarding positions). Every passenger is assumed to optimize his or her generalized travel cost by selecting the waiting position under the constraint of train arrival time and also of platform crowding.
In the second part, our objective is to state a model specification suitable to simulate such traffic situations and scenes in a way both sensible and sensitive. The specification will be an abstract description in the form of a Scope statement, derived from the systems analysis but oriented to traffic simulation.

Déconfinement en France en mai 2020 : objectifs du gouvernement, difficultés et résultats / Deconfinment of France in May 2020 : Objectives of the goverment, difficulties and results

Michel ROSTAGNAT 罗天诺, né en 1956, ancien élève de l’Ecole Polytechnique, membre du corps des Ponts, Michel Rostagnat a conduit une carrière au sein des services de l’Etat chargés de l’aménagement du territoire et de l’environnement.
Il traite depuis longtemps de questions de transports (aménagement du secteur de l’aéroport de Paris Charles De Gaulle, programmation des infrastructures dans le Massif Central, débat public sur le projet de métro du Grand Paris...).
Il est membre du Conseil général de l’environnement et du développement durable, au ministère de la transition écologique, chargé des questions de transports. Il est responsable du suivi d’un accord franco-chinois de coopération dans les transports et préside le groupe de travail transports de la Convention alpine.
Il aime la Chine, son peuple et sa langue, qu’il a découverts à Paris en 2007 par l’association des anciens élèves de son Ecole.
Il est l’auteur de deux essais : Les nouvelles frontières de l’environnement (1993) et Un chrétien dans la haute fonction publique (2007).
résumé : Au sortir du long confinement du pays décrété le 16 mars 2020, le gouvernement français était légitimement inquiet. Allait-on assister, dans les transports publics, à des scènes de bousculade incompatibles avec l’objectif de distanciation ? L’usager méfiant allait-il au contraire déserter le métro, avec le risque de faillite des collectivités locales autorités organisatrices de la mobilité et de leurs exploitants ?
A l’étonnement des observateurs, le déconfinement s’est plutôt bien passé. Les trains étaient peu remplis. Les autoroutes urbaines n’étaient pas saturées. Le printemps a permis l’explosion du trafic vélo, qui n’assure pourtant jamais plus de 5 % des déplacements, et de la marche à pied. Même observation à la rentrée de septembre. Mais quid de l’hiver qui s’annonce ?
Trois paramètres se sont avérés déterminants : le recours au télétravail, le décalage des horaires pour éviter l’heure de pointe et la méfiance du public pour les transports collectifs dans les grandes villes et singulièrement à Paris. Les nouvelles applications fondées sur le suivi des smartphones, depuis les relais de téléphonie mobile ou par satellite, peuvent aider à en rendre compte
L’accompagnement de ce changement de mœurs passera par une vraie politique du vélo, orientée vers les jeunes, une meilleure distribution de l’emploi dans le tissu urbain avec la création de lieux de coworking, et l’adaptation permanente des réseaux. Les entreprises auront à favoriser le télétravail et l’autonomie de leurs employés, ce qui n’est pas dans la tradition française.

Michel ROSTAGNAT 罗天诺, born in 1956, Paris Polytechnique Alumnus, member of the French " Bridges " Senior Civil Servants’ Corps, Michel Rostagnat has pursued his career within the French State Service in charge of Regional Development and Environment. He’s for a long time committed in Transport issues (Paris Charles De Gaulle Airport outskirts planning, planning infrastructures in the Massif Central, consultation on the Big Paris Metro project…). He’s member of the Ministerial Senior Advisers’ Team to the Minister of Ecological Transition, reporting on Transport issues. He’s in charge of follow-up of a Sino-French Agreement on Transport and chairs the Alpine Convention Transport Working Group. He’s fond of China, Chinese people and Chinese language he discovered 2007 in Paris thanks to its Alumni Association. He’s author of two essays : The New Frontiers of Environment (1993) and Christian and French State Senior Civil Servant (2007) (French).
Abstract : Towards the end of the long confinement ordered on 16 March 2020, the French government had good reason to fear disorder in the public transport networks. Would it be there crush, incompatible with the objective of remain distant from each other ? Converse, would distrustful user desert the metro and quicken bankruptcy of local authorities in charge of mobility and of their service providers ?
Amazingly, deconfinement happened rather well. No crowd in the trains. No hold-ups on the urban motorways. Thanks to spring, bike traffic actually exploded (but its modal share remains under 5 %). So did walking. The same was to be seen by September at the start of the academic year. But what about the next cold season ?
There are three key parameters revealed by the crisis : the rise of teleworking, the shift of the time of commuting in the morning in order to avoid peak hours, and the user distrust regarding public transport means, especially in Paris. New applications based on big data processing, caught from smartphones followed by mobile phone masts or satellites, may be helpful to understand it.
Helping this possible revolution of life-style will imply a true bike policy oriented towards young people, a better distribution of work places among the urban tissue with the help of coworking offices and the permanent adaptation of networks. Companies have to promote teleworking and self-behavior of their staff, what’s unfamiliar to the French tradition. That’s to debate now.

Comment le secteur ferroviaire s’est organisé pour faire face à la crise ? / How the railway sector has organized itself to deal with the crisis ?

Marc GUIGON, Directeur Voyageurs de l’UIC, Coordinateur de la région UIC d’Amérique Latine, Coordinateur de la force opérationnelle internationale ferroviaire de l’UIC sur le Covid-19
Résumé : La pandémie Covid-19 a touché l’ensemble de l’économie mondiale, en particulier le secteur des transports en raison des interdictions et des limitations de voyages. Afin de partager les bonnes pratiques des entreprises ferroviaires mondiales, l’UIC a créé une force opérationnelle sur la Covid-19 en février 2020. Celle-ci est composée de la majorité des entreprises ferroviaires et gestionnaires d’infrastructure, mais également des grandes organisations internationales en lien avec ce secteur.

Marc GUIGON is Passenger Director at UIC (International Union of Railways) responsible for Passengers activities, including development of High-Speed Rail in the world, Railway Stations, Distribution, Regional and Commuter Train Services and Tourism in Trains.
He is also coordinator of UIC Latin-American Region and chair of the UIC Covid-19 Task Force, which comprises 70 UIC members and 18 International organisations.
Prior to joining UIC, Marc worked 7 years for the office of the French Prime Minister, responsible for French national policies of transport in the field of spatial planning : including railways, roads, urban transport, airports, ports and waterways.
He was also engaged in the development of Champagne-Ardenne
Region and was the State contact point for questions related to spatial planning in the region.
Lastly, he was responsible for intergovernmental cooperation between France and China
Abstract : The Covid-19 pandemic has affected the entire global economy, especially the transport sector dueto travel bans and restrictions. In order to share the best practices of global railway companies, the UIC created a task force on Covid-19 in February 2020. This is made up of the majority of railway companies and infrastructure managers, but also international organizations related to this sector.
Practices have been exchanged through the creation of databases, media centre, social media and through regular meetings including members from all continents. This task force encouraged solidarity among its members. They did not hesitate to share their knowledge concerning protections against the spread of the disease (masks, ventilation, social distancing, decontamination, etc.), withngreat empathy and a spirit of cooperation. They also openly shared their ways of working, welcoming customers in stations and on trains, setting up offices, etc. They also provided UIC with information on the financial losses suffered by their company in order to establish a global assessment.
The UIC is continuing its work, in order to be able to provide information on the resumption of activity and to define what could be a "new normal" once the pandemic has finally passed

La vie sociale dans les quartiers résidentiels de Shanghai pendant la pandémie / Social Life in Shanghai residential areas during pandemia

Cristiana MAZZONI is an architect, urban designer and Professor of Architecture and Urban design in the National Architectural school of Paris-Belleville (ENSA PB). During her academic career she has been teaching as visiting professor in Italy, Germany, France, Spain, USA and China. She is the Director of the Research Center UMR AUSser, in the framework of the French Scientific Research Center (CNRS) and member of the Metropolitan Development Council of Strasbourg. She is in the scientific committee of the Chinese and French “Innovative metropolitan mobility” Chair (IMM Chair) and scientific director of the “Metropolitan Architecture and Great Events” Chair (MAGE Chair).
In 2008 she founded with Yannis Tsiomis the Atelier CMYT studio and she is the Senior Adviser of CMYT R&D for innovative research in urban architecture. The research and professional works of the studio have been exposed in the Venice Biennale of Architecture 2018 (Palazzo Bembo, “Time, Space, Existence” program), entitled “The Power of urban architecture”.
abstract : Since the 1990s, Shanghai’s metropolitan development has grown exponentially (establishment of the market economy, new housing policies). The renewal of central districts and peripheral expansion have led to a major transformation of architectural and urban forms and a strong increase in the residential population. The residential tower, the evolution of mobility, the extension of the metro networks to the whole metropolitan area, the increase in the standard of living of city dwellers have determined the change of the urban silhouette and the emergence of social problems related to exclusion.
Our presentation focuses on the urban spaces developed around high-rise buildings, located between housing and the city, taking the example of the recently built Zhongyuan Liangwan Cheng district in Shanghai. We question the notion of "life cycle" in the design of these landscaped spaces, and their possible innovative function to create a new urbanity at the scale of the district.
In relation to the wealth of practices that have characterised the life of courtyards and alleys in the lilongs of historic Shanghai, we note that this new design allows for a greater integration of natural components in a very dense metropolis and the blossoming of new practices of collective spaces such as walking, playing and active walking.
These examples of Asian metropolises can provide solutions to the need to rethink housing in new situations of confinement everywhere in the world, including Paris.

NZUDIE KENMOGNE Guy Theophile, Institut Supérieur des Transports of Groupe Supdeco Dakar Sénégal.

An example of a project taking into account sustainable development issues in Africa : Case of the Bus Rapid Transit (BRT) of Senegal

Biography : My name is NZUDIE KENMOGNE GUY THEOPHILE, 27, cameroonian living in Dakar Senegal for more than a year now, academically I am a holder of a Master 2 in Management of Logistics and Transports, a Master of Business Administration In Logistics and Supply chain Management, and also certifications in the same field. I also have about 7 years of professional experience in the Logistics and Transports domain . Today I am a PHD student, a lecturer, a program assistant and Corporate Relationship Manager at Institut Supérieur des Transports of Groupe Supdeco Dakar Sénégal.
Abstract : Abstract :
In order to facilitate the movement of populations from the suburbs to the city center and to fight against congestion and its harmful and varied consequences, the State of Senegal has implemented a transport infrastructure project of urban mobility, taking into account the requirements of sustainable development in order to fight against the degradation of climate change. This innovative and sustainable development project is called the Bus Rapid Transit (BRT) in English or Bus à Haut Niveau de Service (BHNS) in French.

This project is led by the Executive Council of Urban Transport of Dakar (CETUD) whose mission is to implement and monitor the application of the sectoral policy of urban public transport defined by the State, for the region of Dakar, organize and regulate the supply of urban public passenger transport, so as to sustainably improve the operating conditions of operators and, consequently, the movements of the populations of the Dakar metropolitan area.
The BRT project underwent an environmental and social assessment and obtained an environmental compliance certificate issued by the Ministry of the Environment and Sustainable Development more than 3 months before its approval by the Board of Directors of the World Bank on May 25, 2017. Classified in category A for projects, the BRT has strong requirements in terms of reducing negative externalities linked to road transport and inclusive growth.

It is an innovative public transport project that will considerably reduce the travel time between Guédiawaye (starting point of the Bus) and the city center (arrival point at Petersen station) from 90 to 45 minutes in comfortable conditions, substantially improved safety and regularity. In addition, the proportion of the regional population able to access the City Center in less than 60 minutes will increase by 12%, from 57% to 69%.
This new form of environmentally friendly transport will also integrate an automated ticketing system which will allow automatic ticket sales, automatically count passengers on the bus, validate passenger transport cards. Informations of journeys, on the arrival and departure times of buses can be transmitted to users in real time, this will not only promote the use of public transport to the detriment of private transport, but will also contribute to the reduction of emissions greenhouse gases and the reduction of urban traffic.
Contrary to the situation we are experiencing in Dakar with the use of polluting cars due to their obsolescence, this form of transport (BRT) is beneficial not only for the country’s economy because it promotes the fluidity of mobility between several areas of the city, but also it will help to preserve the environment on the long term because the technology associated with it will make it possible to fight against the climate change which the world has been challenging for years now.

Where do cognitively impaired older adults walk ? —Cognitive friendly street for the older adults

Biography : Qi Yuan, PhD Candidate of Tongji University, college of Architecture and Urban Planning, Visiting Scholar of University of California, Berkeley, she has published (including been accepted) more 13 papers in core journals and reviewed papers for International urban Planning, ASAP and TRB as a reviewer. Her research is based on environmental behavioural theory, focusing on the walking environment of urban vulnerable people. Her recent research mainly focuses on cognitively friendly environment.
Abstract : Abstract :
The positive effect of physical activity in the prevention and treatment of many chronic diseases and age-related disabilities, such as cognitive impairment, are widely accepted. Despite the growing interest in encourage walking among cognitively impaired older adults, there is a limited understanding of the walking behaviour of this particular subgroup of the population.
Cognitive functioning is critical for day-to-day life, especially for older adults, governing their thoughts and actions. As the growth of age, older adults physically and mentally produce different degree of degradation : memory deterioration, reaction speed slow, distraction and sensory function decline, resulting in loss of independence in daily activities and disability in older age. 10% of seniors over 65 and 50% over 85 are suffering from mild cognitive impairment, the number of people with dementia is around 50 million, and there are nearly 10 million new cases every year worldwide.
However, systematic reviews have shown limited effects of pharmacological interventions on treating dementia, whereas some recent public health research emphasizes the positive role of physical activities in older people’s cognitive health. For older adults, walking is reported as a favoured form of physical activities. Studies have proved that physical activities, especially walking, benefit older adult’s physical and mental health in terms of enhancing individual memory ability, accelerating cognitive processing speed, and reducing the incidence of cognitive decline and Alzheimer’s disease. Walking outside also increases social contact and communication for cognitively impaired older adults, and hence help alleviate their fears of leaving their homes and better engage with their communities.
There exists a large body of studies attempting to identify factors contributing to more walking among healthy older adults, and a consensus on the positive effects of the built environment has been reached. Older adults living in neighbourhoods with more walkable environments are generally found to be more physically active and have better health outcomes as compared to those who do not. However, whether this link is still present for cognitively impaired older adults has rarely been studied.
Using data on community-dwelling older residents from four neighbourhoods in Shang Hai, this paper aims to address the aforementioned knowledge gaps by examining whether built environments are associated with leisure walking behaviour of cognitively impaired older adults using CART model. In addition, given the enormous disparities in demographic characteristics and cognitive preference of cognitively impaired older adults, we also examine whether these associations differ among these features.

The Expansion and Remodelling of the Concept of “Traffic Safety”

Biography : Master of Urban and Rural Planning, School of Architecture and Urban Planning, Hua zhong University of Science and Technology, master’s degree in urban and rural planning, tutor Professor Guo Liang, the research direction : sustainable urban and rural planning and design theory and methods, transportation and urban and rural society (space) development, healthy cities, urban transportation and land use integration, public transport-oriented development.
Abstract : Among the many future traffic projections, 2020 brings with it some new variables, adding a lot of thought to the public health dimension of the city. In the past, traffic often ignored similar thinking, on traffic, only consider the operation of a simple system, on this level, the future traffic as an important part of the system, in addition to close ties with the economy, but also exist in the various living scenes of urban residents.
The new topic revolves around "safety", where traffic safety in the past meant avoiding accidents or preventing crime on public transport and subways, and where the primary responsibility of many national transport administrations is safety, it now appears that it must include "public health safety". As a result, crowds will continue to be prevented in the future and a range of measures will be taken. For high-volume public transport, the project is not only a huge investment, but also needs to be fast and good into daily production and life.
But people can also have other options, during home isolation, digital remote virtual methods become the main way of work, education, etc., while the isolation period of e-commerce consumption increased, home delivery service dependence is becoming stronger. And these are shown in traffic, and if you don’t need to travel (commuting and non-commuting), production life can change dramatically. In this way, the new "digital security" also seems to be an important new area of traffic.

Le Collège des hautes études du développement durable et le Living Lab / The CHEDD and the Living LAB Ar Nevez

Jacques BREGEON est Directeur de l’Ecole des Métiers de l’Environnement (Ker Lann, South of Rennes)
Chairman of Compétences 21 since 2010.
Abstract : The College of Higher Studies on the Sustainable Developpement was a national project and is now a regional initiative of Brittany, managed by Jacques Bregeon.
It aims at developping a think tank between the regional experts and concerned persons to identify the element of a pertinent strategy for the whole region, including the metropolises but also the numerous small cities and villages who want to overcome current difficulties and avoid future risks of climate change, health risks, lack of renewable ressources …

Abstract : This association aims at concentrate many actors of ecoactivites on the specificities and ambitions of a low dense territory (Redon Agglomeration, 60 000 inhabitants ) inorder to share expertise and combine operational strategies to facilitate the transformation of the territory.
The difficulty is to induce a processus of convergence between private enterprises and public bodies to create a « learning territory » where concrete actions icrease collective skills and capacity of building complex projects and export the knowledge in other territories.
The attractivity of Redon is linked to traditions of agriculture and agroindustries, as well as the technical performance of several industries in advanced sectors, supported by professional platforms sharing the education of specialised experts in robotic, logistic, physical, chemical and biological measurements.
In the coming months and years, the objective is to focus the projects on the needs of the inhabitants, and to give answer to the main questions about energy, sustainable mobility, circular economy, prevention of pollution not forgetting to include the entire population in the constraints and benefits of the transformation.
