  • Abstract:
    "The aim of this project was to provide electrical engineering support for the telemetered traffic monitoring sites (TTMS) operated by the Statistics Office of the Florida Department of Transportation. This project was a companion to project BD-543-12, which provided civil engineering support for the same sites. The project consisted of three main efforts that are detailed in this report. The first task was to conduct efforts to improve modem communication with the TTMS sites. The second task was to conduct field and laboratory testing to specify and identify lightning surge suppression devices to protect the TTMS's electronics (communications and classification) from lightning surges. The third task was to develop interface electronics for and support field testing of a segmented sensor design to identify dual versus single tires. This identification can lead to improve vehicle classification accuracy. The results of the first task were verification of communication equipments used and development of refined modem strings. This increased the reliability of the communication with the TTMS sites reducing the need for manual collection of traffic data. The second task resulted in an initial characterization of the lightning surges, specification of surge suppressor requirements and identification of appropriate surge suppressors to protect the TTMS equipment. The third task resulted in the development of a prototype electronics interface and a successful field test demonstrating the feasibility of the segmented sensor to improve classification. This project has resulted in lower maintenance costs for the TTMS sites and potentially improved classification performance"--Technical report documentation p.
