The Inductive Loop Vehicle Detector:Installation Acceptance Criteria and Maintenance Techniques.

摘要

The paper describes techniques to improve the operation and reliability of Inductive Loop Vehicle Detectors. Three aspects are discussed:Installation design aids,installation acceptance criteria and maintenance techniques. The paper is divided into two sections,the first titled 'To the Traffic Engineer'and the second 'To the Maintenance Technician'. The emphasis is on practical solutions to design,installation and maintenance problems. Technical data is provided,based on measurements of test loops located at the California Transportation Laboratory's Detector test site. All loops tested were 6feet (1.83meter) 'square'loops consisting of three turns of 12 AWG (20gage metric) wire.
