Project detail
Project Description:   Phase I: (1) A vehicle component server was programmed. An open-source flow microscopic model probe vehicle on the surface street accepted 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 were traveling on the freeway were 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. A phase II as been awarded.
Goals:   The key project objective is to create a traffic modeling tool that is optimized for transportation research rather than transportation operations.
Background Information:   The purpose of this project is to develop a tool for research that can be marketed to traffic researchers rather than to traffic operations personnel.
Test Methodology:   See project description.
Partners:   U.S. Department of Transportation: Research and Innovative Technology Administration (RITA); Role(s): Other stakeholder
Expected Benefits:   The expected benefit is the development of new techniques for research into simulation modeling.
Project Findings:   Phase I demonstrated that it is 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 code base 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.
