MODEL OF TRAFFIC LIGHT CONTROL SYSTEM USING SMART PHONE

Abstract

This research presents a model of traffic light control system via smartphone, which simulated at Ban Khlong intersection, Muang district, Phitsanulok province. The data of this study had been collected in 4 periods of time during weekdays. The amount of traffic density was determined to decide the design of traffic light control system that are appropriate for the time period and increase the efficiency of traffic control. The microcontroller raspberry pi was used as processor. A number display monitor was used to indicate times and closed circuit camera was used to monitor number of vehicles. The designs of traffic light control system using smartphone include 2 systems such as automatic system and semiautomatic system. For the automatic system, the traffic light control system was automatically changed for all 4 ranges. The traffic light control system was controlled by traffic police for the semiautomatic system. The both system model was controlled via a smartphone. The results showed that the comparisons during a normal traffic light control system and the traffic light control system using smartphone in the morning at 05:00 – 11:00 am., the efficiency of the traffic light control system using smartphone was higher than the normal traffic light control system 22.05%. In the afternoon at 11:00 – 17:00 pm., the efficiency of the traffic light control system using smartphone was higher than the normal traffic light control system 30.64%. In the evening at 17:00 – 23:00 pm., the efficiency of the traffic light control system using smartphone was higher than the normal traffic light control system 20.43%. At night during 23:00 – 05:00 am., the efficiency of the traffic light control system using smartphone was higher than the normal traffic light control system 26.88%. Finally, the achievement of traffic light control system using smartphone was higher than the normal traffic light control system 22.05% for daylong. A model of traffic light control system using smartphone could be developed for solving traffic problem in the future.
