SECTION 6 – TRAFFIC AND LIGHTING 84 6-2.4 CONTROLLER CABINET WRAPS Section under development. 6-3 SIGNALS 6-3.1 GENERAL For traffic signal installation, an engineering study should be performed to determine the validity of signal installation. New traffic-signal proposals should satisfy at least one (1) or more of the primary warrants listed in IMUTCD Chapter 4C. The IMUTCD provides the criteria and procedures used to determine if the warrant is satisfied. If a traffic signal is not warranted a multi-way “Stop” sign application may be appropriate. The warrants provided in the IMUTCD should be followed. The IMUTCD describes the warrants for where a multiway “Stop” sign installation may be considered. However, it should not be used unless the traffic volume for each approach leg of the intersection is approximately equal. Signals require a surge protector and battery back-up system with blue light indicator, LED signal indication modules (all colors), back plates on all signal heads, and pole mounted supplementary signal heads for all new signal installations or modernization projects, otherwise existing conditions may be maintained. New signal installations shall also provide fiber optic, Ethernet radio, or cell modem connections to the Centracs central management system. Contact the Bureau of Traffic and Lighting to determine which connection type is appropriate for the intersection location and for specific requirements on equipment and standards. Pedestrian heads with count down display and push buttons are required where marked crosswalks exist, are planned, or pedestrian volumes warrant. After the installation and acceptance of a traffic signals by the City of South Bend, the City will become responsible for the operation and maintenance. Therefore, the City should be consulted early in the design process regarding the feasibility of the selected signal equipment and its location, e.g., controllers, cabinets, signal heads, etc. The selected equipment must satisfy the operator’s capability to adjust the signal and maintain. To reduce the City’s n eed for additional resources and personnel training, the design shall match existing traffic signal hardware and capabilities. All traffic signal equipment is to be barcoded. Contractor shall provide a list to the Bureau of Traffic and Lighting. The Bureau will create the bar codes which are then to be secured to the equipment by the contractor. 6-3.2 TRAFFIC SIGNAL CONTROLLERS The controller shall be a TS2 Type 2 controller, a malfunction management unit (MMU), and be interchangeable with existing controllers used and maintained by the City of South Bend. The controller shall have a small switch panel and compartment (police door).
