Application and Suitability of Signal Coordination
Author:
Abstract: The aim of this study was to apply signal coordination for eight signalized intersections in three
different locations and compare the performance before and after the adjustments. To achieve the above
objective, we collected traffic data from the sites and from the ministry of works. VISSIM software was used
for evaluation and analysis of intersections. SYNCHRO software was used for finding the best timing plan
alongside manual solution (trial-and-error). We got a high delay and bad level of service for all of the selected
intersections before applying the signal coordination. Then the improvement strategy of optimizing signal
timing and coordination was applied to the traffic flow in the study areas. Finally, this improvement was found
to have good effect on the level of service and delays, where we reduced the delay in all the locations by
approximately 34% and improved the level of surface from F to E on Estiqlal highway and 16th December
Highway and from D to C on Tubli highway. The strategies and design from this research can be implemented
on the selected locations and serves as a benchmark for other similar studies in the region.
