Project Description:	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: (1) Examine the state of the art in open source traffic signal controller logic.(2) Convert the Path Logic to run on the prototype development hardware.(3) Develop interactions with traffic simulator for extended testing.(4) Integrate selected elements of the National Cooperative Highway Research Program 3-66 signal state transition logic.
Laboratories:	Not Applicable
Start Date:	August 22, 2012
End Date:	February 19, 2013
Funding Amount:	$149,096.00
FHWA Program Name:	Small Business Innovation Program (SBIR) (2% of Adjusted CA)
Goals:	The key project objective is to develop a logic for signal state transitions that follows in the footsteps of the National Cooperative Highway Research Program (NCHRP) 3-66.
Project Type:	Offsite
Background Information:	They were able to test SCOPE at a live intersection in Orlando, Florida. They were supported by the Orange County Traffic Division. The final report's last section contains photos and information about the testing. In recap, this is the first time SCOPE ever ran with a MMU in the cabinet. The MMU detected 2 minor problems that were easily taken care of. No phase conflicts were detected. The test was a success with live traffic flowing through the intersection.
Test Methodology:	Houston Transtar signal laboratory conducted testing with their signal test equipment. Orange County, Florida conducted real world testing.
