on historical split information or use other capable system detectors to maintain adaptive operations .
Provide all hardware necessary at each intersection for the installation of the Hardware A daptive Traffic Signal System including the following:
• Adaptive Traffic Signal Processor .
• Equipment .
• Spare equipment .
• Web-based/adaptive system application/adaptive signal system interface and setup (if applicable) .
1.a. Adaptive Traffic Signal Processor .
• The system must provide equipment as necessary to communicate between the detection system(s) and the traffic adaptive components of the system.
• The system must automatically send all necessary information to processors at neighboring intersections to optimize the phasing sequence, duration, and initiation of movements along the corridor .
• The system must be capable of passing all vehicle detection inputs through to the controller to allow the intersection to operate without adaptive control by manual command, time of day, or if an adaptive processor failure occurs .
• When the controller loses communication with the processor, the controller must default to using existing time -of-day timings in conjunction with the vehicle detectors. To accomplish this, all vehicle detection must be passed through to the controller if adaptive processor failure occurs or a need to disable adaptive operation in the future. Do not operate t he system in “free mode” due to a loss of communication between the controller and the processor unless directed.
• The system must have a “free mode” contact closure pin wired in the cabinet so if communication is lost between the hardware adaptive system and the controller, the intersection will revert to a previous time of day plan and generate an alarm , SMS text message or email, to inform TMC /system operators.
1.b. Equipment.
• Provide a minimum 10/100 plug -and-play Ethernet connection with static IP.
• For systems that connect detection into the adaptive signal system processors, i nclude a lightning arrestor and fuse block to protect the power leads to the vehicle detectors.
• Allow power to be remotely cycled to the vehicle detectors.
• Provide one 7 -inch monitor and integrated Universal Serial Bus ( USB) keyboard /mouse for the entire system. The keyboard must have key spacing center -to-center of 0. 75 inches with a minimum 84 keys. The monitor and keyboar d/mouse must allow full monitoring and configuration of the adaptive system at each controller cabinet. The monitor must have a minimum resolution of 1024 x 768. Upon final configuration of the adaptiv
