Development of the System of Monitoring Traffic Vehicle Volume and Density on the Vietnam’s Street

The article presents the solution to monitoring traffic vehicle volume and density on the Vietnam’s street, applied image processing technology and IoT. The system includes hardware (traffic cameras, processing board-IoT, server computer) and Apps, Web programs. The system uses traffic cameras to collect input data for software programs to identify and detect vehicle on the street, traffic violations vehicles, determine the traffic vehicle volume and density on the street and then show them on Apps, Web. The article focuses on developing the IoT-based processing board, the algorithms to identify the traffic vehicle volume and density on the street, recognize vehicle number plates, detect traffic violations vehicle and warn of collisions of vehicles participating in traffic. The test results show that the proposed system works well, the software program achieves high efficiency with an accuracy of 95.49% in counting vehicles.
