VEHICLE DETECTOR LOOP CABLES

This report presents the findings of the final phase of an investigation, the purpose of which was the selection of traffic detector loop configuration, their lead-ins, their wires, and their installation, on a sound engineering basis. The investigation includes not only theoretical and practical studies of the electrical, mechanical and environmental properties of wires, but also an analysis of the transformation of the detection information between lead-in input and output. Loop wire insulation studies, with respect to its electrical properties and mechanical and environmental bearings, are also included. A questionnaire was prepared to obtain comments on electrical and mechanical problems of loops from those with practical experience in the field. Detailed recommendations for traffic loop installation and suggested areas for further study are presented.
