PMSS Project Details

Project ID:	FHWA-PROJ-10-0016
Project Name:	SPAT with an Intersection Collision Model (101-FH3) SBIR Phase 1
Status:	Completed
Contact:	Last Name: Gibson First Name: David P Telephone: 202-493-3271 E-mail: david.gibson@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Operations Research and Development
Team:	Trans Enabling Technologies Team
Roadmap/Focus area(s):	Not Applicable
Project Findings:	The tentative answer is that signal phase and timing (SPAT) can be simulated with an intersection collision model, and that the combined model might be useful for safety and operations research.
Project Description:	Harmonia has developed an index of Traffic EXperimental Analytical Simulation (TEXAS) documentation, documented global variables and subroutines in Simulated Processing (SIMPRO), and added newly developed subroutines into the TEXAS documentation database. Harmonia has developed the Enhanced Traffic EXperimental Analytical Simulation (eTEXAS), a Java Application Programming Interface for the TEXAS Model. We have set up SIMPRO for compilation using free and open source software and modified the TEXAS source code to accomplish the central step of reorganizing TEXAS as a simulation library for programmatic invocation by the Connected Vehicle program or other applications. We have also implemented Java interfaces to the simulation for portability for the Society of Automotive Engineers (SAE) J2735 messages, Variable Message Signs messages, Signal Controller Messaging System (SCMS) messages, and obtaining vehicle updates. In addition, we have developed a graphical user interface for Delta Time (DT) simulation and a simplified Java version of Bonneson's Dilemma zone Control Systems (D-CS) algorithm for validation of eTEXAS. Harmonia has also created a project website to host the free and open source eTEXAS project, which includes source code, documentation materials, and developer community facilities.
