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.


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.

Project Output: 

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.
