Description

Toll collection system in a multi-lane highway hi-pass environment based on vehicle detection and toll charging using optimized sensor deployment The present invention relates to a toll collection system that detects vehicles and charges tolls through the optimization of sensor placement in a multi-lane Hi-Pass highway environment. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. Highway toll collection systems have evolved from a method where drivers stop at toll booths to pay with cash or cards to the Hi-Pass system, in which tolls are automatically settled via dedicated short-range wireless communication between terminals mounted on vehicles and roadside base stations. In the Hi-Pass system, technology that rapidly detects vehicle entry and terminal status is crucial to enable vehicles equipped with payment terminals to pass through without stopping. Conventional highway toll collection systems utilize various sensors, such as loop coils, infrared sensors, and RFID communicators, to detect the presence of vehicles and determine whether they have entered the Hi-Pass lane. However, these systems suffer from issues including sensor misrecognition, false detection due to spacing between vehicles, the inability to distinguish abnormal entry in real-time, reduced accuracy in vehicle location identification, and sensor signal errors caused by vehicle conditions. Consequently, these problems can lead to toll collection errors, fraudulent passage, and terminal failures. Therefore, there is a pressing need for more precise and reliable vehicle detection technology to prevent these issues.
