• Abstract:
  The arterial traffic signal performance measures were not used to their fullest potential in the past. The development of traffic signal controllers with event-based, high-resolution data logging capabilities enabled the advances in derivation and visualization of traffic signal performance measures. Florida Department of Transportation (FDOT) engaged in an effort to standardize those measures across various traffic controller types to ensure uniform implementation of such practices in the future controllers’ deployments. This report contains the findings of a study whose goal was to investigate the capabilities and features of six different controllers from six vendors, which were connected simultaneously into a Hardware-in-a-Loop Simulation (HILS) test setup. The first objective of the study was to determine the minimum standards that the new event-based high-resolution traffic signal controller needs to fulfill to be approved for future installations in Florida. For this purpose, a unique set of mandatory and optional event codes was determined. The second objective was to check ability to retrieve and consistency of various performance measures from different controllers. The characteristics of each controller, the procedures for building the HILS test setup, controller configurations, retrieving of the high resolution data locally (by using File Transfer Protocol), and the online tool (FDOT server) for calculating and graphically representing relevant performance measures (Purdue Coordination Diagram, Percentage of Arrivals on Green, Platoon Ratio, and others) were tested.
