Topic Description:  Continous Risk Profiles For Safety Improvement

Improving the safety of the roadway has been the priority for Caltrans - and to this end, Caltrans has been monitoring the traffic collisions that occur on freeways and identifying a list of sites that need to binvestigated for further safety improvements.
