Research Institution
Research finding during Phase I of this project have led the research team to conclude that it is feasible to use 60-Hz samples from single loop detectors in order to perform re-identification between loop detector stations on freeways. The method employed was robust to loop calibration errors, easily corrects for metadata concerning the exact location of the loops and demonstrated that it was possible to re-identify vehicles up to 1.5 miles away (which was the extent of our test section). This project proposes to productize this research by implementing the software in the commercial archive data management systems, PeMS. We will then perform large field tests of this methodology in both a congested, urban area as well as in a rural area in order to demonstrate its effectiveness over a variety of conditions. These tests will be done on live freeways with the support of Caltrans.
