OPTIMIZATION OF TOLL SERVICES USING QUEUING THEORY IN THE CASE OF ETHIOPIA

The toll road service is planned and built to fund construction management of traffic operations. Although the has several benefits, it also challenges by creating a queue in event high traffic. Queues at addition pollution waiting time costs expose drivers accidents affect economy country. Queuing problems highway gates exits due have become main concern for transport managers planners because randomness inter-arrival time. critical point services finding optimal number servers. This paper aims analyze feature optimize using analytical simulation models considering Addis-Adama expressway Ethiopia. used mathematical model CPN tools investigate queuing parameters. Then results helped us get optimum output economic analysis identifying minimum operating cost without expense. performance highly depends on servers, vehicles system queue, time,
