Intersection Collision Avoidance: From Driver Alerts to Vehicle Control

Intersection Collision Avoidance (ICA) based on Dedicated Short Range Communications (DSRC) is one of the most promising applications for vehicle communications. System implementations based on vehicle sensors suffer from field of view limitations that vehicle communications do not exhibit. This makes particularly interesting the adoption of DSRC in combination with other onboard sensors to address intersection crash scenarios. State-of-the-art DSRC-based intersection collision avoidance systems, notably the Intersection Movement Assist (IMA) application, are aimed to issue audible and visual alerts to the driver. This paper describes an implementation of Intersection Collision Avoidance that extends the IMA concept to cover a wider range of intersection collision scenarios and introduces automated braking as a system response when a high risk of a collision is detected and the driver does not react to the alerts.
