การแก้ไขปัญหาสภาพจราจรบริเวณด่านเก็บค่าธรรมเนียมผ่านทางลาดกระบัง บนทางหลวงพิเศษระหว่างเมืองหมายเลข 7 โดยประยุกต์ใช้ระบบกล้องอ่านป้ายทะเบียนรถยนต์ (LPR)

Abstract

Traffic congestion at the Ladkrabang toll plaza on Motorway No. 7 showcase a significant challenge, impacting both safety and travel efficiency. This is particularly pronounced in the Bangkok-bound direction (inbound), where the traffic flow rate is considerably lower than the Chonburi-bound direction (outbound). This discrepancy stems from the closed toll collection system, which requires drivers to return a toll card and verify the fee before making a payment. This process leads to queuing on the inbound side, increasing the risk of accidents. While the Department of Highways has implemented reversible lanes to alleviate congestion during peak hours, this measure has not yielded a sustainable solution. This research focuses on addressing traffic congestion at the Ladkrabang toll plaza by implementing a License Plate Recognition (LPR) system on the outbound side. This aims to expedite toll booth passage and reduce the number of toll booths required on the outbound side. Microscopic Traffic Simulation was employed to analyze and model the impact of this approach. The study found that this approach facilitates infrastructure improvements and allows for an increase in the number of toll booths on the inbound side. Moreover, it enhances traffic flow rate, reduces queue length, and decreases travel delays. These findings can be applied to develop and improve traffic management strategies, ultimately enhancing the efficiency of traffic flow at the Ladkrabang toll plaza sustainably.
