Other software used in the industry include Syncho 5.0 and SimTraffic. Both of these software are produced by Trafficware Ltd. and thus they both work very similar to each other. Synchro 5.0, the LOS analysis software, also calculates Intersection Capacity Utilization (ICU) which provides additional insight as to how well an intersection is functioning and how much extra capacity is available to handle future growth, traffic fluctuation and incidents. The ICU calculation does not use existing signal timings or sign control. It simply calculates the ultimate capacity based on a fully protected, optimized signalized timing plan at a cycle length of 120 seconds.
