Abstract: The line up service model at parallel toll station, based on the traffic arrival subject to the standard Poisson distribution, has some shortages in time and space complexity, cost, reliability and other aspects. Concerning these shortcomings, this paper presents an analytical method to review the traffic capacity, delay and setting number of serial toll station which is set based on cellular automata modeling and simulation. The study results show that the traffic capacity of serial toll station is increased with its setting number but the increment is becoming slower; the critical point of average traffic delay of serial toll station is at the level of eighty percent of traffic capacity, and average traffic delay will increase sharply over this point. This paper gives the best setting number of serial toll station at different flow levels.

Key words: traffic flow, serial toll station, traffic capacity, average traffic delay
