THE PERFORMANCE EVALUATION OF TRAFFIC MANAGEMENT SIMULATION MODEL IN RUSH HOURS FOR PHRANAKHON RAJABHAT UNIVERSITY

This research developed the extended work of a simulation model to estimate the waiting time in the queue at the exit gate of the Phranakhon Rajabhat University, 2 new traffic management models have been created to find the model for decreasing waiting time in queue. The previous models had occupied a special lane for vehicles enter to the rector office, and another had used human control at the exit gate to hold traffic on the main road and let vehicles pass through the exit gate. The results found that waiting times in queue at the exit gate of 2 previous models are not much different due to the natural traffic jam on Chaengwattana road which is the main road where the exit gate is connected to it and only one exit gate to depart from the university. So, this research studied the 2 new models by adding 2nd exit gate to evaluate the waiting time in queue in hoping that waiting time in queue of 1stexit gate is decreased. However, the results show that the waiting time in queue at the 1st exit gate has not much decreased in difference after adding 2nd exit gate due to the majority of vehicles coming to the university to drop off their children and some are vehicles belonging to the officers of the university, those vehicles pass over the junction to use the 2nd exit gate to depart the university. Those vehicles will go through the 1st exit gate and wait in queue to depart the university. Then, the second models created by adding human control at the junction in front of the primary school building to force vehicles to come to the second exit gate at some period then waiting time in queue at the 1st exit gate is decreased and the number of vehicles which get into the Chaengwattana road had increased when compared to the same time at the 2 previous models.
