Summary Information

The City of Scottsdale implemented a project to upgrade its aging loop detection infrastructure with video-based vehicle detection technology. As part of a Bicycle Signal Detection program, the City replaced loops at 17 intersections with 62 video-detection cameras and the associated hardware and software.

Total Estimate

The City of Scottsdale required specific physical, functional, and performance characteristics for its video-based vehicle detection system. The system selected included software that discriminately detects the presence of individual vehicles and bicycles in single or multiple lanes using only the video image.

Detection zones used only an embedded software application. A monitor, keyboard and pointing device were used to place the zones on a video image. A minimum of 32 detection zones per camera view were available.

The CCU was a standard 19-inch rack format that was designed to fit into Traffic Signal 330 style cabinets. The CCU incorporated video surge suppression for each video input and was appropriately grounded to the cabinet ground rod using 14 AWG minimum. The CCU provided a Wi-Fi connection over a standard 2.4GHz connection. The Wi-Fi connection was enabled and disabled by a switch on the CCU. The CCU provided an indicator when the Wi-Fi connection was active.

The camera imager employed a WDR technology to compensate for wide dynamic outdoor lighting conditions. The dynamic range is greater than 100 dB.

The video detection system software also supported bicycle type zones where the zone could differentiate between motorized vehicles and bicycles, producing a call for one but not the other.
