Project detail
Roadmap/Focus area(s):   Intersections
Project Description:   This is a Small Business Innovation Research Phase II project that will develop a final Dilemma Zone Safety Intelligent Transportation System, which can detect and warn vehicles that risk running into a dilemma zone at a high-speed intersection. The system also has the capability to extend green time to avoid a dilemma zone situation and improve safety at the intersection.
Goals:   The key project objective is to improve high-speed intersection safety and operations.
Background Information:   Dilemma zone problems have been a major topic for a long time. With new wireless communication technologies, microprocessing, and Light Emitting Diode Flashers, there is an opportunity to build a more effective dilemma zone safety system.
Field Test:   Yes
Product Type:   Hardware
Research report
Software
Test Methodology:   Field Test
Expected Benefits:   The expected benefit is a significant reduction in crashes caused by dilemma zone problems at high-intersections.
Deliverables:   A functional system that can improve intersection safety.
