Abstract
With the latest improvement done on North Luzon Expressway (NLEX), it is expected that the number of riders for both North Bound and South Bound will rise. For a more continuous flow of traffic, an Electronic Toll Collection (ETC) system was introduced to help alleviate traffic congestions; specifically at Toll Plazas. The paper shows how the introduction of NLEX’s ETC system helped alleviate traffic by decreasing the service times at Toll Plaza; thus increasing the capacity of motorists it can accommodate. By using Queuing Theory, the researchers were able to show the significant difference in performance of Toll Plazas when using ETC. The paper also expounds on the factors that contribute to the delays and long queues experienced at Toll Plazas and recommends ways to help improve the service.
