Evaluation of Loop Detector Installation Procedures and Preparation of a Texas Traffic Signal Detector Manual (Revised).

摘要

The report summarizes the results of a broad series of studies dealing with the installation of loop detectors. The studies initially used the older type detectors commonly in use by local governmental units. The later studies used the Texas series detector units which are remarkably more sensitive than their earlier counterparts. This study includes consideration of a wide range of loop detector design factors including design of the loop system, placement of the loop wire, loop shape and loop location relative to the intersection. It also includes installation procedures for saw cutting, sealants and electrical properties of the loop.
