Service time is one of the key factors for the operation and performance evaluation of toll plazas. The service time is found to be dynamic in nature depending upon vehicle-class, traffic composition, toll rate, drivers’ and tollbooth operators’ behavior. The present study aims to evaluate the service time variation under mixed traffic conditions considering seven vehicle classes. The mean service time was found to be low for a small car (SC) and high for Trailer as 10.47 seconds (s) and 33.69 s respectively. Furthermore, the leader-follower pair’s effect on service time variation is also evaluated, selected thirteen-pairs with SC as leader or SC as a follower is considered. The results indicate that the average service time is minimum for SC-SC pair and maximum for Trailer-SC pair as 10.42 s and 33.81 s respectively. The relationship between toll rate and service time shows the polynomial as the best fit.
