• Abstract:
  In our previous research, the SMART-SIGNAL (Systematic Monitoring of Arterial Road Traffic and Signals) ; system that can collect event-based traffic data and generate comprehensive performance measures has been ; successfully developed by the University of Minnesota. In this research, a new set of interfaces are developed for ; SMART-SIGNAL system including new prototypes of data collection unit (DCU) and refined web-based user ; interface. To collect high resolution event-based traffic data including both vehicle detector actuation event and ; signal phase change event, two types of DCUs are designed, the TS-1 DCU and TS-2 DCU for corresponding ; traffic signal cabinet. TS-1 DCU connects with TS-1 cabinet using pin to pin interface, and the TS-2 DCU ; interfaces directly with SDLC bus within TS-2 cabinet. The DCUs uses high performance microcontroller modules, ; and are compact and easy to install. Both DCUs are designed to be vender independent add-on module for traffic ; cabinet, and can be used as flexible solution to enhance data collection by agencies. The refined web-based user ; interface features various performance measures to public users, such as Level of Service (LOS), queue length, ; travel time and intersection delays. The new set of interfaces have been deployed with the SMART-SIGNAL ; system at 13 intersections along Trunk Highway (TH) 13 in Burnsville, MN.
