Colloquium 2022 – Transforming mobility towards more sustainable urban futures

For its second edition, the Anthropolis Colloquium showcases our multidisciplinary research outcomes from 2021-2022. Through the eyes of a family and their neighbours, you will discover our vision on how to tackle today and tomorrow’s daily mobility challenges: How much time will we spend in shared autonomous shuttles? Will we be encouraged to walk more with Mobility as a Service? How would different 2030 scenarios impact our way of life? What is our relation to sustainability challenges across local, regional, and national scales? If you wish to know more, join us on 16 September 2022 from 9-17 CEST on the Campus Paris-Saclay!

Free but mandatory registration – In-person attendance recommended, online attendance possible.

How to include the environment in mobility decision-making? Insights from a territorial perspective
By Julien Baltazar (CentraleSupélec)

Our story takes place in the inter-council partnership of Paris-Saclay. Its strong development dynamics make the design of its mobility ecosystem challenging. This presentation aims to present the context of future mobility in Paris-Saclay: How is mobility organised and planned? What are the main sustainability stakes? How are environmental impacts taken into account for the choice of the forthcoming mobility developments? What are the limits of current practices, and what could be improved for better decision-making?

How can we make mobility infrastructures more sustainable?
By Flore Vallet (IRT SystemX and CentraleSupélec)

Mobility infrastructures are connected to public spaces: they constitute a spatial resource, shared, dynamically managed and (potentially) flexible. We conducted a structured analysis of various strategies to make mobility infrastructures as sustainable as possible, considering technological opportunities but also organisational and behavioural ones. Through several practical examples, we introduce interdependent questions to challenge the sustainability of mobility infrastructures, from the usage, data, and material intensity, to the artificialisation of soils, resilience, or the promotion of safety for users.

Appraisal of walking in MaaS solutions: Exploring a piece of the puzzle for future sustainable mobility
By Mariana Reyes (IRT SystemX and CentraleSupélec)

Mobility as a Service gathers different transport services from different providers and natures (public/private). However, pedestrian mobility is not a service like any other and as such, innovation around walking and its related benefits risk being ignored when developing and implementing MaaS solutions. Despite that, pedestrian mobility concerns about 40% of individual trips in Île de France. Not taking it into account for the development of Mobility as a Service (MaaS) solutions means ignoring the needs of all these Ile-de-France residents. In this research, we focus our attention on the governance of the MaaS ecosystem and the respective stakeholders’ perspectives towards walking in order to identify strategies for the appraisal of pedestrian mobility that could translate into societal, environmental and economic benefits at individual, organisational and territorial levels.

Casablanca multi-modal balanced floating Catchment area (CMBFCA) for measuring spatial accessibility to healthcare facilities
By Ouidad Benhlima (LGI-CentraleSupélec / Centrale Casablanca)

The presentation is about calculating spatial accessibility to public hospitals using a new metric based on the balanced floating catchment area measurement. The latter metric addresses open data issues while considering different transportation modes and catchment sizes.

12:45-13:45       LUNCH

13:45-15:45      Session 3: Urban mobility transitions: How might we move tomorrow?

Decision support under uncertainty for design processes of urban mobility solutions for sustainable futures
By Tjark Gall (IRT SystemX and CentraleSupélec)

We provide an overview and examples of a design and decision support method developed as part of a doctoral project at the Anthropolis Chair. The method integrates future trends and uncertainties to prepare better today’s design process for tomorrow’s mobility solutions. 2030 scenarios of Paris-Saclay support two applications cases: 1) Testing intermodal mobility-on-demand solutions, and 2) Prioritising and selecting interventions to increase active mobility.

Urban forms and human transport. Modelling the co-evolution of new mobility modes and transportation networks
By Michele Tirico (Future Cities Lab and CentraleSupélec)

Historically, the introduction of new mobility modes has shaped urban forms (for example, the invention of internal-combustion engines has led to heavy environmental infrastructures, strongly contributing to urban sprawl). Nowadays, with the recent introduction of e-scooters, the higher consideration of active modes, the expected introduction of autonomous vehicles and the development of mobility-on-demand services, it could be argued that we are approaching another transportation revolution.
In this work, we present a formalism to investigate how existing ad predicted mobility modes, technological innovations, and human behaviours shape the transportation system.

An agent-based simulation assessment of the future of mobility in the area of Paris-Saclay
By Tarek Chouaki (IRT SystemX and CentraleSupélec)

Major changes are planned on the public transport side, with new lines coming into service in the Île-de-France region in general and, more specifically, in Paris-Saclay. The Grand-Paris Express project and future tramway lines will directly impact travellers: the routes they will take and the time it takes to perform their trips. Using agent-based simulations, we will be able to assess future lines’ impacts on the considered individuals’ mobility.

On-demand mobility with electric autonomous vehicles: An optimisation approach
By Yue Su (CentraleSupélec)

With the astounding growth in automobile ownership, there has been a series of transport-related problems worldwide (e.g., greenhouse gas emissions and urban traffic congestion). Two efficient methods are proposed to reduce these problems: using electric vehicles and investigating ride-sharing services. The Dial-A-Ride Problem (DARP) consists of designing minimum-cost routes by scheduling a fleet of vehicles to provide ride-sharing services to a set of customers who specify their origins and destinations. In recent years, many demand-responsive systems have been constructed, such as the mobile-based app of BlaBlaCar in France and Didi Hitch in China. With the resurgence of on-demand ride-sharing services, how to strike a good balance between operational costs and user convenience becomes a big challenge.
