« Urbanloop and traffic synchronization » presented by Jean-Philippe Mangeot

During the next meeting of the CO² team on Thursday, October 22nd at 2pm, Jean-Philippe Mangeot will give a seminar on Urbanloop.

This one will take place in the CRAN meeting room at ENSEM as well as by videoconference on Teams (link: Join the Microsoft Teams meeting).

Title : Presentation of Urbanloop

Description :

Until the 19th and 20th centuries, mass public transportation systems were public transport in the sense that passengers all shared the same vehicle: bus, train, metro, streetcar, trolleybus. This concept has the advantage of pooling the 2 resources that were once the most expensive in a transportation system: its driver and its engine. In this context, it was more economical and cleaner to transport passengers simultaneously in the same container than in any other existing individual means of transport. In the 21st century, this is no longer the case. For example, in the urban cycle, the added energy consumption of 30 electric scooters is less than the energy consumption of an electric bus. These technological advances in electric propulsion and in the field of automation are leading society to rethink the concepts of public transport in depth, in particular by considering that a public transport system can be more efficient by moving passengers individually in light and compact vehicles than together in heavy and bulky vehicles.

This is Urbanloop's guiding idea when applied to rail vehicles. Nevertheless, the synchronization of the traffic of a fleet of a large number of vehicles on one rail poses several scientific problems, in particular that of defining the best architecture of the control system. Currently, for reasons of simplicity, the solution chosen to control the capsules is a centralized architecture type "one master and all slaves". However, another collaborative architecture in the sense of "autonomous mobiles" would have advantages such as minimizing the cost of the control and command infrastructure and communication.

The objective of this seminar is to identify research works or themes relevant to CRAN's research activities that could bring a technological added value, in the short, medium or long term, on the particularities of the Urbanloop system.  You are all welcome to attend.
