: Movement of people and goods has become more difficult last decades, especially within urban
areas. Traffic congestion level has continuously increased as dependence on passenger cars has gone up. This
has led to significant travel delays, increase of travel costs and pollution. Signalized intersections are an
important part of urban transportation system which mainly are considered bottlenecks of the system. Hence,
their operation condition gains top importance for a better and smother movement of vehicles. One of the least
expensive improvements of intersections which in turn brings about high improvements is signal split
optimization and coordination. This study focused on analyzing the cost-benefit ratio of improvement of signal
coordination for high volume arteries. Measures of Effectiveness (MOEs) like delay time, number of stops, fuel
consumption, pollutant emission and performance index was analyzed by SYNCHRO, a widely used software for
signal optimization and coordination.
