Characterize Dynamic Dilemma Zone and Minimize its Effect at Signalized Intersections

Intersection dilemma zones are one of the major factors contributing to traffic-signal-related crashes. The primary objective of this project is to develop quantitative models measuring dynamic dilemma zone (DDZ) dimension, traffic features over DDZs and their relationships with potential for signal-related-crashes at high-speed signalized intersections. Potential countermeasures to minimize/eliminate DDZ's affect on safety and mobility will be investigated. The result will provide a basis and support for traffic engineers in the development of effective strategies and tools to reduce dilemma zone in the design and implementation of signalized intersections. The result will also provide a basis to develop a framework for studying DDZ issues related to layout of detection systems when applying adaptive signal control systems and/or Intelligent Transportation Systems (ITS) measures.
