PMSS Project Details


Project ID:FHWA-PROJ-10-0034
Project Name: Dilemma Zone Safety Intelligent Transportation Systems Phase II
Status: Completed
Last Name:Huang
First Name:Peter
Office: Office of Operations Research and Development
Team:Trans Ops Concepts and Analysis Team
Roadmap/Focus area(s): Intersections
Comprehensive Approach to Safety
Safety Data and Analysis
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.
Laboratories: Transportation Operations Laboratory
Saxton Transportation Operations Laboratory
Start Date: August 1, 2010
End Date: February 3, 2014
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.
Test Methodology: Field Test
Expected Benefits:The expected benefit is a significant reduction in crashes caused by dilemma zone problems at high-intersections.
Deliverables:Name: Final research report and a prototype system.
Product Type(s): Research report, Software, Hardware
Description: A functional system that can improve intersection safety.
Keywords: Intersections
