The County does not have a signal communication network or a monitoring system for signal operations. The County needs an Advanced Traffic Management System (ATMS) along with all their signals connected to the ATMS allowing County staff to monitor and manage the traffic signals in real time. Also, the County needs updates to traffic cabinet components to include new controllers, supporting devices, battery backups, and key location remote monitoring cameras. Thus, allowing issues to be addressed efficiently allowing the signals to operate at optimal performance.
