Contribute to the safety case of CAVs by making the infrastructure more intelligent using sensors and iVRIs.

Connected Automated Vehicles (CAVs) are in development. In public transport, CAVs in the form of automatic driving shuttles have been applied in various locations in recent years as a promising new solution for the commute on the last kilometer. In tests on public roads, a Steward is always present in the CAV to ensure safety. The complexity and variety of traffic situations combined with the guarantees that must be given for the safety of automatic driving mean that driving without human supervision is not yet possible. The question arises whether and to what extent roadside systems (communication between the Vehicle and the Infrastructure = V2I) can support and accelerate this process?

What we do

Commissioned by the Metropolitan Region Rotterdam The Hague (MRDH) an analysis was made on the current systems that can increase traffic safety by making the environment smarter. These are sensors such as LiDAR, Radar and cameras with smart software. These were added to a mobile iVRI installation with which tests could be carried out.

This information can make an important contribution to several ongoing or pending projects where CAVs have to deal with an iVRI (smart traffic light), or where a further future without a steward (physically in a shuttle) is envisioned.

Currently, it is being tested how the communication between shuttle and iVRI can contribute to the safety case and will be tested for operation. During this test a mobile iVRI installation with additional sensors will be placed at the test location and an automatic shuttle will be driven here. In the shuttle an OBU(on board unit) is placed which will communicate with the RSU(Road side unit). This allows the shuttle to receive green or red light via a message. Through this form of communication, this message can act as operator-go, or give the shuttle priority at the intersection.

Why we do it

There is a lot of experimentation with automated transport in the Netherlands. The complexity and variety of traffic situations combined with the guarantees that must be given for the safety of automated driving mean that driving without human supervision is not yet possible today. 

To increase safety the environment of the automatic shuttle should be made smarter, this can be done by adding sensors and a smart traffic light system. If the automatic shuttle communicates with these sensors and a smart traffic light, this would enable the safe crossing of intersections. The communication between the vehicle and the infrastructure is called vehicle to infrastructure (V2I) communication.
