A Comparative Analysis for Signal Timing Strategies Under Different Weather Conditions
This paper provides design and evaluation of two signal timing strategies with five cases respectively under different degree of weather condition. The main aim of this project is finding out the most suitable signal timing strategies depending on the weather condition by comparing the analysis results. The procedure mainly includes two parts in traffic signal design, which are signal timing plans design and performance analysis. Methods of design and performance analysis include Webster’s signal timing method, Akcelik’s signal timing method and HCM delay method. It is clear that the weather factor has huge impact on performance of signalized intersection. Apparently, compared to strategy B, strategy A is more suitable for bad weather condition.
