Inclement weather commutes can take significantly longer than those occurring under normal conditions. While traffic volumes are often lower, the combination of reduced speeds and capacity cause severe congestion, especially in signalized urban networks. Signal coordination that reduces traffic congestion in normal conditions results in an uncoordinated and insufficient timing plan during inclement weather. However, central communications can now change signal timing plans as necessary, allowing a library of signal timing plans including those for inclement weather conditions. The Utah Traffic Lab monitored traffic flow data for 7 inclement weather severity conditions at 2 intersections in the 1999/2000 winter season. This paper presents and discusses results from the collected data of this study.
