Project detail
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.
Goals:   Evaluate whether it is possible to utilize enhanced loop sensor amplifiers to measure and track vehicle signatures to create anonymous travel time and origin-destination information.
Background Information:   The purpose of this project is to develop a tool for research that can be developed into an easy to use tool for measuring traffic performance measures for traffic operations personnel.
Product Type:   Hardware
Research report
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.
Deliverables: Name: Proprietary loop signature amplifier for identifying and reidentifying anonymous vehicle signatures.
Product Type(s): Research report, Hardware
Description: see name
Project Findings:   Phase I demonstrated that it was possible to utilize special loop amplifiers to measure the pulse intensity in high resolution time intervals. Phase I demonstrated that different classes of vehicles gave different vehicle signatures. Phase II will investigate the uniqueness of the signatures and whether they can be used for vehicle identification and reidentification.
