Title
Purchase of Vehicle Detection and Traffic Signal Equipment (B)
This item is a request to purchase vehicle detection and traffic signal equipment from Temple, Inc. for the replacement and repair of vehicle detection systems at traffic signals in the amount not to exceed $250,000. This equipment is also related to the Traffic Management System.
Explanation
In order for traffic signals to operate efficiently and reduce congestion and delay, vehicle detection systems at each traffic signal must be operating properly. As part of the Traffic Management System, broken and inoperable vehicle detection systems are being replaced. This will allow staff to maximize traffic flow on corridors and minimize delay on both major and minor streets.
Temple, Inc. is the vendor for two (2) traffic vehicle detection manufacturers, Iteris and Sensys. Iteris Vantage video detection systems and Sensys magnetometer detection systems are used by the traffic signal controller to detect vehicles. This allows the intersection to operate more safely and efficiently. This operation is called fully-actuated control. Purchasing detection equipment will enable every intersection to operate as fully-actuated. Studies have shown that broken detectors can add as much as 20% to travel times and delay to isolated and coordinated intersections. Video detection is an alternative to cutting loops in the pavement where asphalt is likely to fail. Magnetometers provide wireless detection from small pucks in the roadway that transmit wirelessly back to the traffic controller.
Fourteen (14) intersections will require a detection upgrade to either of these systems in the near future. Other intersections may be changed out as existing detection breaks down and is inoperable.
Fiscal Note
Funding in the amount of $250,000 for this purchase from Temple, Inc. is available in the Public Works FY10 operating budget and the Traffic Management System CIRB of the 2005 Capital Project Fund. ...
