Common use of Vehicle Detection Clause in Contracts

Vehicle Detection. (1) Detection Zone Placement. The radar detection system must provide flexible detection zone placement anywhere within the combined field of view of the radar sensors. Preferred presence detector configurations are lines or boxes placed across lanes of traffic or lines placed in-line with lanes of traffic. A single detector must be able to replace 1 or more conventional detector loops. Detection zones must be able to be fully overlapped. In addition, detection zones must be capable of implementing logical functions including delay timing. These logical functions may be excluded if provisions are made to bring each detector separately into the controller and the controller can provide these functions.
