General questions regarding this page should be directed to Gary Bell via Internet e-mail. Extensive analysis of accident data was performed to define collision problem areas and causal factors. Based upon these, and other considerations such as related human factors research activities, projects were initiated to develop performance specifications for countermeasure systems and progress has been made in the development of new research tools. Finally the overall benefits to be derived from introduction of CA products will be estimated and refined based upon the above factors. Each of the projects in the program provide specific input to improving the overall knowledge base and understanding of systems that address one or more problem areas.
Intersections are among the most dangerous locations on U.S. roads.
There are more intersection collisions than any other crash type. However, it is also more technically challenging to prevent this type of crash with detection and warning technology than other crash situations. Because of these technical challenges, this is viewed as a longer term program area, but one with potentially large safety benefits. They occur most often on metropolitan arterials and streets. A collision avoidance system that reduces this type of collision will also help decrease travel delays caused by this type of collision in addition to improving safety.
