National Cooperative Highway Research Program 3-66

completed

National Cooperative Highway Research Program 3-66 has developed a real-time traffic signal State transition logic software. This logic allows local intersection control programs to be aware of the distinctions between different kinds of preempts and the meanings (e.g., the difference between railroad and light rail preempts, fire trucks, ambulances, police, and mass transit vehicle priority requests). This project will develop versions of the National Cooperative Highway Research Program 3-66 logic in C and Ada programming languages to ride to work with Path traffic signal control program logic and the real-time Linux advanced transportation controller operating system for the advanced transportation controller. Objectives of this research study are to: Examine the state of the art in open source traffic signal controller logic. Convert the Path Logic to run on the prototype development hardware. Develop interactions with traffic simulator for extended testing. Integrate selected elements of the National Cooperative Highway Research Program 3-66 signal state transition logic.
