Project Details

Project Description: 

Phase II: (1) Developed basic simulation model based on open published algorithms and papers. (2) Developed C++ project to share data between operating programs. (3) Develop a server client architecture for programs. A phase II has been awarded.(4) Develop a database architecture for input output streams.(5) Develop architecture for handling multiple turning and auxiliary lanes.(6) Added linkage to coordinate cumulative and time interval measures of effectiveness  with graphical files.


The key project objective is to create a traffic modeling tool that is optimized for transportation research rather than transportation operations.

Project Findings: 

Phase I demonstrated that it was possible to create a traffic-modeling tool optimized for research in Fortran 2000 that can be interfaced with object-oriented programming tools. In phase I, the feasibility of creating an open-source flow microscopic model was explored. The model and its corresponding software are based on the same codebase as the CORridor SIMulation (CORSIM) base: (1) A vehicle component server is programmed. An open-source flow microscopic model probe vehicle on the surface street accepts the keyboard control of its location from the client side through the component-based application programmer interface. In the second case, the lanes on which vehicles are traveling on the freeway are controlled by a client through the keyboard input via the component-based application programmer interface as well. (2) Critical gaps about running an open-source flow microscopic model with intelligent transportation systems hardware and communications and with the Traffic EXperimental Analytical Simulation (TEXAS) intersection collision model were explored. (3) Detailed discussions of laboratory tests were presented to Federal Highway Administration staff.
