Installation Report, State Demonstration Project, Loop Detectors

Report No: 83-R15

Published in 1982

About the report:

The Virginia Department of Highways and Transportation frequently utilizes induction loops in its vehicle detector systems. Although not documented, there have been many instances of loop failure; therefore, the practices and materials used by the Department in installing loop detectors were investigated. Two field tests were undertaken- the encasement of the loop wires by PVC conduit and vinyl tubing and the performance of different types of loop sealants. This report documents the installation of these two field demonstrations. Findings based on the installation are given; however, further findings, conclusions, and recommendations will be developed after an appropriate evaluation period.
