Abstract

State of the practice signal timing techniques at isolated actuated controlled intersections often result in sub-optimal operation. This paper proposes using new sensing techniques to identify inefficient split allocation. This new information can be used to develop real-time flow rate information to estimate real-time volume-to-capacity (v/c) ratios for strategic split reallocation and/or for logging purposes to evaluate the performance of an intersection over a period of time. Data was collected to confirm public reports of a short left turn phase and identify during which time periods this occurred. As a result, a 5 second split reallocation was implemented. Graphs illustrating before and after v/c ratios of movements involved in this split reallocation are presented.
