Traffic flow monitoring systems are the main instruments that change the level of the efficiency of the traffic signal control system and the traffic denseness to be less. As a rule, six main technologies are used for traffic flow detection. These technologies are induction loops, microwave detection, infrared sensing, ultrasonic detection, video detection, and millimetre-wave radar detection. Out of these six, video detection is the method that is the most extensively utilized. Cameras may be regarded as inexpensive sensors for the collection of video data, and they are very simple in terms of their installation and maintenance. Hence, they are extensively utilized on roads and at checkpoints for traffic safety monitoring and electronic enforcement purposes.
Video detection, as compared to other detection methods, is less vague and of a bigger size since it can literally depict the traffic scenes. The system, through digital image processing and machine learning, can identify vehicle types, understand traffic signage, and recognize pedestrians.
Over the last several years, millimetre-wave radar detection has attracted the most attention from the civilian sector. Because of its strong anti-interference characteristics and ability to operate under any weather conditions, it can work for 24 hours a day and, thus, is the most appropriate sensor for intelligent transport systems. Nevertheless, traffic scenes are complex, and frequently a single sensor cannot fulfill all the application requirements. As video data is more dependent on the environment and lacks some data such as distance, speed, angle, and depth, whereas radar data is less detailed. Therefore, the integration of radar and video in traffic monitoring systems not only provides a larger and more accurate set of vehicle data but also the system's overall power is increased along with the data precision.
The data gathered from the sensing devices like millimetre-wave radar and video detectors is dealt with by the flow monitoring technology. Here, processing means data cleansing, standardization, and iterative model updates. This, in turn, opens the way for the full management of static information, dynamic information, and path information.
Vehicle identification technology based on deep learning and the currently available front-end video detection hardware carries out the structured analysis of video images. Historical traffic flow data for entry/exit points are obtained through video detection and tracking techniques, which are then further divided into categories based on factors such as time of day, day of the week, and specific location.
After that, data analysis and mining methods are employed to work out local traffic distribution at major and minor intersections, changes in traffic density for different time intervals, and entry/exit trends within the area. It is a tool that makes it possible not only to ascertain the general level of traffic congestion but also to find out the exact number of vehicles that are at a standstill at the moment. Besides, by overlapping the data on parking facilities and that on the total parking spaces in the area, the system figures out the parking space utilization rates as well as similar data, thus, providing another function of on-street parking management in the form of decision support.
The video detection instruments are installed on each major and secondary road segments that require monitoring. The devices perform real-time vehicle movement route detection, calculation of entry and exit traffic volume for each road section, summarizing of the entry and exit traffic volume of all main and secondary roads, as well as estimation of the total number of vehicles in the area.
