With the development of traffic, the urban intelligent transportation market has witnessed an increasingly larger scale and traffic information acquisition and release systems have been used more and more in the last two years.

The dual-radar microwave vehicle detector of our traffic information acquisition and release system is a product for detecting traffic data such as traffic flow, average vehicle speed, vehicle type and lane occupancy rate in real time with help of the digital radar microwave detection technology.

The detector operates in the way below: It can be hung on the side of a street lamp post or a special column. Vehicles are detected when passing through the radar wave areas emitted by the microwave generator. The detector has two built-in radar transceivers that generate two microwave beams projecting two detection areas on the road surface. Each time a vehicle passes through one of the detection areas, a microwave signal will be reflected to the detector. Speed and other traffic information of the vehicle will be obtained accurately after complicated computation and analysis. A detector can detect the traffic flows, road occupancy rates and vehicle speeds of eight lanes at the same time.

Through certain information transmission media, the traffic information acquisition and release system is actually a traffic control mode providing traffic participants with practical traffic information and reminding, suggesting or controlling them to choose the best routes to avoid or reduce delay and losses.

It has two information guidance modes, i.e. a static one and a dynamic one. It can release traffic status, accidents, announcements and other traffic information to travelers or vehicle drivers through traffic control centers so that they can choose the best routes, thus guiding traffic flows effectively, controlling and balancing traffic flow distribution reasonably and improving road utilization and traffic smoothness to enable drivers to drive safer and more quickly. In the modes set by users, it can display information related to the contents entered by users, including weather, traffic facility overhaul, driving of special vehicles and the real-time traffic information of roads acquired by traffic signal control system, traffic flow acquisition systems and traffic video monitoring systems. At present, LED guidance signs are one of the foremost and most effective traffic guidance methods.

?Based on our nearly two decades’ rich research and development experience in the intelligence industry, we have provided total solution meeting the practical need and the trend better and had lots of successful cases. The real-time information such as vehicle flows, speeds and types and lane occupancy rates provided by the traffic information acquisition and release system provides an efficient and accurate data support for traffic control management, traffic information release, etc. This system has been successfully used in places such as Guangdong, Hunan, Shanxi, Anhui, Sichuan, Guangxi and Henan and is popular among customers.
