Vietnam highway reinforces toll collection with LPR solution

The Cau Gie-Ninh Binh Expressway stretches for 50.3 kilometers from Hanoi to National Highway 10 in Nam Dinh Province and has a speed limit of 100-120km/hr. The dual three-lane expressway aims to help ease traffic on National Highway 1A while cutting the traveling time in half between the nation's capital and provinces in the south of the Red Delta.

The expressway adopted the ITS (intelligent transport system), which is provided by Messoa partner CadPro in Vietnam. One of the critical parts in the system is toll stations, which were set up at the entrances and exits throughout the expressway to collect charges based on travel distance and vehicle types. To facilitate the toll collection process while ensuring the smooth operation at each station, Messoa LPR/ALPR traffic cameras were chosen for deployment at these locations.

Solution
Each lane is covered by 2 Messoa cameras, an SCR515PRO and an SCB290 for license plate capture and overview respectively. Powered by Messoa's advanced CatchAll Technology, the SCR515PRO is specifically designed for license plate recognition. The camera is able to minimize extraneous noises on the road, such as rain, headlight, and smoke/fog. The camera is also designed to capture razor-sharp license plate and overview traffic images in all lighting conditions under various speeds.


Alongside with the SCR515PRO, the SCB290 is a true day/night camera to provide a wider overview monitoring of the of the entire toll booth lane. Installed right above the SCR515PRO, the camera covers vehicles with a much taller body, such as charter buses or tow trucks. Built-in with Messoa's proprietary Lumii Technology to enhance the low light performance, the camera is also able to accurately capture high-resolution images of the make, color, and other critical information of the passing vehicles.

Results
Having combined the video solution with the toll system, the monitoring center is able to keep track of the toll staff behavior and the vehicle flow at each station. The recorded footage can be used as references to ensure whether the toll has been properly collected. Should any fee-related dispute arise, the footage can provide key evidences for settlement. All of which enables better management of electronic information flow in the ITS.

Project leaders of the Vietnam Express Corporation were satisfied with the video monitoring results they have seen. Toll collection has been smoothly operated without any major incidence. As of now, 39 tolls are installed with the Messoa cameras, and 27 tolls will be completed soon in the later phase of the project.
