The remaining 38 traffic signals are monitored and controlled by a recently installed Management Information System for Traffic (MIST). The City is in the process of converting all traffic signals to the MIST system and due to the size and complexity of the project, the implementation is divided into eight phases based on geographical areas.

A total of 120 traffic signal controllers and 30 cabinets have been upgraded thus far.

Staff recommends the purchase of the equipment to complete the project. 22B-1
