Abstract

Analysis of the level of service of the Lopez Avenue ? National Highway intersection in Los Baños were done in the previous studies. Optimal signal timing phase routine was determined by quantifying different traffic parameters such as control delay and volume-to-capacity ratio considering different traffic controls and scenarios like considering no volume of tricycles and assuming no volume flow-through vehicles. Synchro was used to analyze the intersection. Due to urbanization, traffic volumes continue to increase, making Synchro reach their methodology?s limitations. To provide meaningful results, microscopic simulation tool, such as SimTraffic, should be used to analyze the transportation network. Traffic counts during peak period were conducted using video camera and the data was used to obtain intersection delay using Synchro 6. Delay was also measured by observation. Since the relative errors between delays obtained in Synchro and manual observation were very high, calibration of parameters (travel speed, turning speed, headway factor and lane change distance) was done for all movements to obtain the optimal calibration parameters and simulation values for this intersection. Setting the travel speed to 20 mph and turning speed to 7 mph and 12 mph, for right turns and left turns, respectively, will give the lowest relative error. On the other hand, optimal calibration parameter for the PM peak hours was obtained by setting the turning speed to 11 mph and 19 mph, for right turns and left turns, respectively.
