Signalized Intersections
The service is to provide information to road users to support safe and efficient crossing of signalized intersections. The implementation of the use cases should increase safety and traffic flow efficiency and reduce adverse environmental effects following from erratic and stop-and-go driving.
NordicWay Presentation Signalized Intersections
The video shows an example of an implementation of the services, however the services can be implemented and used in different use cases as described below.
Background
Road intersections represent complex traffic environments where traffic flows may be impeded in different ways, where risks for accidents are higher, and where fuel consumption and adverse environmental effects are high due to stop-and-go driving.
Providing road users with information for passing intersections should allow them to adapt their driving behaviour for safe and smooth passing of intersections.
Objective
The objective is more attentive driving.
