What does the acronym WRM stand for in traffic management?

The acronym WRM stands for Walk Rest Modifier in traffic management. This term is used in the context of pedestrian signal timing and the planning of pedestrian facilities. The Walk Rest Modifier helps in adjusting the timing of walk signals based on the needs of pedestrians, particularly in areas where walkers may require additional time to cross streets safely. It takes into consideration factors such as the walking speed of the pedestrian population, the length of the crosswalk, and the overall flow of pedestrian traffic.

Understanding this modifier is crucial for traffic engineers and planners as it directly impacts pedestrian safety and the efficiency of pedestrian crossing times, especially in urban settings where pedestrian and vehicle interactions are high.
