Assessment of the Cooperative Intersection Safety System (IRIS)

Henk Barmentlo, B-Assignment at Peek Traffic BV, April-June 2009

Peek Traffic BV is a part of the stock exchange listed company Imtech. It has offices in Poland, Belgium and the Netherlands. The office in the Netherlands is located in Amersfoort. This is the location where I will assess my Bachelor Thesis. From this office, mobility systems are provided to clients all over Europe.

Peek Traffic BV specializes in electronic and software solutions for traffic and transport problems. Key factors in the provided solutions are efficiency, safety and pollution prevention. The company tries to provide new products to optimize these factors through innovative products, often developed in cooperation with other companies and organizations.

The field of my thesis is for Peek Traffic BV part of a cooperation with more than 50 European partners, the so called SAFESPOT project, which in itself is a part of the 6th European Framework Program. It aims to increase the safety on the road, especially around intersections. It therefore uses Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication, which helps drivers to discover safety issues and warns individual drivers about dangerous situations they are about to take place in.

The SAFESPOT project contains many smaller projects. One of them is the Intelligent Cooperative Intersection Safety System (IRIS), a system that specifically aims to reduce the number of accidents at controlled intersections. It tries to analyze the movements of every individual road user and identifies dangerous situations that might lead to accidents. It then informs and warns car drivers of these situations using V2I communication. The IRIS application splits the sensing of danger in three possible situations: Red light violation of crossing vehicles, the encounter of vehicles that have green light at the same time, while other right-of-way rules apply and the encounter of vehicles with pedestrians or bicyclers that have green light at the same time, while the vehicle turns right and pedestrians cross straight ahead. These three factors have different safety factors that need to be assessed and are all different in use and handling.
