Evaluation of Adaptive And Fixed Time Traffic Signal Strategies: Case Study of Skopje

Signalized intersections and belonging signal plans are powerful means for effective urban traffic management. Numerous strategies have evolved over the time, from fixed time to intelligent signal plan control strategies that respond and react to traffic conditions in real time. This paper presents an evaluation and comparison of the impact of fixed time and UTOPIA adaptive traffic signal control strategies for the chosen urban corridor in the wider center area of the City of Skopje, Macedonia. A topic that still requires more attention from the research community. This paper presents a continuation of the author’s previous research where a framework to test UTOPIA adaptive control using the microscopic simulator VISSIM was described. Obtained new results include the influence of fixed time signal plans which are compared with UTOPIA’s results and analyzed in details using the following performance measures: delay, queue length, travel time, intersection level of service, number of stops and vehicle throughput.
