Description:
There are four major component of MMITSS field version: Intelligent Signal Control (I-SIG), Signal Priority (SP), Mobile Accessible Pedestrian Signal System (PED-SIG) and real-time performance observer (PERF-OBS).

Intelligent Signal Control (I-SIG) I-SIG provides real-time adaptive signal control to general vehicles by allocating green time of each phase intelligently. I-SIG takes vehicle trajectory data from BSMs and solve for optimal signal schedule in terms total delay minimization or total queue length minimization. The optimal signal schedule are implemented to Signal Controllers through NTCIP commands.

Signal Priority (SP) Signal priority provides priority to different modes of vehicles including transit, trucks and emergency vehicles. Priority eligible vehicles receive SPAT, MAP and SSM from RSE when they enter the DSRC range and generate SRMs. RSE considers all the active requests from different vehicle and solve for optimal signal schedule in terms of minimization of priority vehicle delay. The optimal signal schedule are implemented to Signal Controllers through NTCIP commands.

Mobile Accessible Pedestrian Signal System (PED-SIG) PED-SIG includes a smartphone application and two RSE applications that can send pedestrian signal request and provide assistance to disabled pedestrians. The RSE broadcast Pedestrians map information through WIFI and the smartphone application receives the MAP and sends pedestrian signal request. RSE will put pedestrian signal request to the Signal Controller.

Real-time Performance Observer (PERF-OBS) PERF-OBS monitors all the users on the road through BSMs and collects real-time performance data by movement by mode such as travel time, delay, and queue length etc.
