Thesis Description:

“Cooperative perception and communication system for protection of vulnerable road users”

Accidents between vehicles and vulnerable users (pedestrians, bicyclists,…) often result in fatalities and serious injuries, showing the need of technology to protect vulnerable people.

Nowadays, vehicles are equipped with many sensors to model their environment, to localize themselves, detect and classify obstacles, etc. They are also provided with communication devices in order to share information with other road users and the environment.

In this context, the thesis is proposing a new cooperative system between vulnerable people (pedestrians, persons with with reduced mobility, bicyclists,…) and intelligent vehicles in order to improve safety and limit collision risk.

On vehicles side, the system is divided into four parts: obstacle detection, tracking, and classification, sensor-triggered vehicle-to-pedestrians (V2P) communications, fusion between perception and communication information, collision risk estimation.

On pedestrians side, the system is composed of three parts: reception of V2P messages, collision risk estimation and pedestrian-to-vehicle (P2V) messages emission.

Cooperative Vehicle-to-Pedestrian Safety System

First, we focused on obstacle detection, tracking and classification using vehicles embedded sensors. More specifically, we decided to apply machine learning methods to classify road obstacles by defining geometric features in laser measurements.

Then, we studied distributed Wi-Fi communications which have the capabilities to disseminate information with low delay in both line-of-sight (LOS) and non line-of-sight (NLOS) conditions. We also evaluated the accuracy of GPS based positioning for estimating the level of danger in a safety system.

In addition, we developed an application that periodically broadcasts vehicles position and dynamics towards pedestrians. When obstacles are detected by the perception system, alert messages are disseminated to specific geographical areas. Pedestrians can receive these V2P messages on their smartphones and acknowledge this reception by sending back their position and dynamics to the vehicles. This application can alert simultaneously vehicles and pedestrians of dangerous situations.

Finally, we are investigating fusion between perception and communication information to take the benefits of both systems: high range and robustness to occluding obstacles for V2P communication, accurate position estimation and high detection capabilites at low range for perception.
