Abstract

Pedestrians are a group of people that have higher risks to have an accident and death. as compared to drivers or passengers traveling by car at the percentage of 13 in the Southeast Asian region. The researchers could find the main problem that most people do not follow traffic rules. Therefore, this study aimed at studying the behavior of pedestrians at crosswalks around traffic lights in the city of Chiang Mai. Then, there were planning and design for the appropriate time of traffic lights on the pedestrian route. The data in this research was collected by video recording on the footpath. The results demonstrated that the speed of male pedestrians was faster than female’s, and the speed of pedestrians in the same age range was relatively similar speed. The average walking speeds of male and female under 18th, male and female between 18th to 60th and male and female over 60th pedestrians were 1.42, 1.30, 1.55, 1.50, 1.38 and 1.37 m/s respectively and the maximum flow rate saturation is 43 ped/min/m. The study of the vehicle virtualization program by analyzing pedestrian population, the optimum duration of the signal light that allows pedestrians to cross, and the appropriate duration of the light signal that allows the mobile vehicle must be appropriate with the population of pedestrian and vehicle volume at that time, the population of 500-1,000, 1,001-2,000 and 2,001-3,000 ped/h. is suitable to the period of time that allows pedestrians to cross the road at 10 seconds. The optimum duration of the light signal that allows vehicles to move is 240-300, 120-240 and 30-120 seconds respectively.
