Approximate analysis of traffic congestion in AGV system

This paper deals with a merging section of the Automated Guided Vehicle (AGV) system under a time for merging. Near the merging section, one flow of traffic must form a queue to avoid collision of vehicles. The vehicle behavior is analyzed using approximate analysis with the Markov chain approach ; the analysis is based on an idealized model. It is important to consider the behavior of traffic at merging sections in the design of the overall AGV system, and also in the realization of the system. We derive the average queue length and the average waiting time by using recurrence. The relationship between queuing delay and traffic density is examined. Therefore, we can make quantitative analysis of the behaviour of traffic.
