Traffic Responsive Plan Selection (TRPS) control is one of the largely underutilized control features in NEMA traffic controllers. This control feature allows the controller to change timing plans in response to changes in traffic patterns, and can therefore result in better performance of the signal system. However, there is a limited number of studies that documentthe procedure of TRPS configuration. The authors have previously published general guidelines on TRPS system setup and configuration, following a comprehensive approach that assumes general traffic patterns, a standardized arterial network, and some generic system detector locations. This paper, illustrate the TRPS configuration methodology on a small arterial network that does not correspond to the standardized guidelines. In this paper, the authors provide some insight into the TRPS configuration process, highlighting some challenges and potential solutions for field problems that the engineer might face when configuring a TRPS control system.
