Vietnam Highway ETC Diviotec

LPR To Combat Lost Tolling Revenues

Introduction

This case study aims to share and feature the unique solution of using DivioTec installation on highway ETC (electronic toll collection) in Vietnam.

Challenge

Capturing imagery travelling at high speeds that can recognize, track and compile lists of passing vehicles.

Solution

Mounted on high gantry collects valuable road traffic data on open highway road in Vietnam. DivioTec solution helps traffic authorities and highway management organizations to monitor traffic, optimize traffic control, collect road toll and generally streamline transportation. It can deal with free-flow high speed as well as stop-and-go traffic situations, recording each vehicle that drives through the gate so that no vehicle remains undetected.

The Radio-frequency identification (RFID) system collects and read the registered tag. But there are some tags might be damaged, uninstalling or any other issue to fail the collection and therefore let the collectors lost revenue. With the installation of LPR, once the RFID system missed reading, the ANPR recognition becomes important proof. The two systems is achieving high percentage of reading and collect the passing vehicle.

Result – High Contrast with Increased Accuracy

With 5MP high-de nition resolution, DivioTec LPR camera captures more than 2 lanes of images in accurate and precise details. It also means fewer cameras are required on the gantry to monitor multiple highway lanes, saving the hardware cost, maintenance cost, software license cost, and installation cost.

For LPR recognition, we selected professional LPR camera TBR923, this model comes with an IP67-rated, power coating housing that offers protection against rain and dust to ensure functional operation in all types of weather conditions.

DivioTec is the first to design SmartCatch™ SoC, which incorporates LPR mode and Overview mode into one camera. With LPR mode, the camera is able to isolate high contrast license plate numbers from the moving vehicles to improved accuracy for LPR and ALPR solutions with consistently crisp, clear images of vehicle license plate characters.
