Project details

What

This shuttle service, operated by Transdev for VEDECOM, aims to build a liaison between the Massy-Palaiseau multimodal train station and the Polytechnic campus. Connections between these two areas are already available in the existing public transport system through regional rail service, national high speed train, and night buses. The EVAPS pilot provides on-demand night shuttles which use dedicated bus lanes. The vehicles follow a fixed route with four station based stops and are accessible on demand, and to wheelchairs. Along their route, the shuttles encounter mixed traffic on private estates, mixed traffic on public streets and mixed traffic on bus tracks.

Why

It is essential that the existing infrastructure is equipped and connected as it is the only way it will allow the operation of AV fleets on existing open/semi-dedicated roads. The general aim of this pilot is to demonstrate the benefits of connected infrastructures and of the safety and efficiency of this type of service.

Budget & Financing

The budget of the pilot is €12m. It is financed by the National funding (PIA) and through private funding (partners).

Challenges

There were some challenges with the mixed traffic situations such as pedestrians crossing, other vehicles, vulnerable road users (RUs), bi round-abouts and night traffic.

Lexicon

7 words explained

platooning

Also known as flocking. A collection of (automated) vehicles that travel together, actively coordinated in formation. Platoons decrease the distances between vehicles using electronic, and possibly mechanical, coupling. Platooning allows many vehicles to accelerate or brake simultaneously.

urban setting

High density environment with an efficient high capacity public transport system with good capillarity and high frequencies.

suburban setting

Medium density environment with a good public transport system with radial connections to the city center, but lower capillarity and frequencies. This setting includes suburban cities.

small cities

Small, isolated city with an own public transport system and <100K inhabitants.

rural

Low-density environment, small cities and villages with poor public transport services mainly connecting the villages.

SAE level

The SAE (Society of Automotive Engineers) levels define the level of vehicle autonomy, or in other words, how much human intervention is still needed for an automated vehicle to operate. Currently, five SAE levels have been defined: Level 0: Automated system issues warnings and may momentarily intervene but has no sustained vehicle control. Level 1 (hands on): Driver and automatic system share vehicle control. The driver must be ready to retake full control at any time. Level 2 (hands off): The automated system takes full control of the vehicle (accelerating, braking, and steering). The driver must monitor the driving and be prepared to intervene immediately at any time if the automated system fails to respond properly. Level 3 (eyes off): The automated system takes full control of the vehicle (accelerating, braking, and steering). The driver must monitor the driving and be prepared to intervene immediately at any time if the automated system fails to respond properly. Level 4 (mind off): As level 3, but no driver attention is ever required for safety, e.g. the driver may safely go to sleep or leave the driver's seat. Level 5 (steering wheel optional): No human intervention is required at all. An example would be a robotic taxi.

V2X

Vehicle-to-everything (V2X) communication is the passing of information from a vehicle to any entity that may affect the vehicle, and vice versa.
