At present, traditional speed checkpoints require the installation of a flat speed radar for each lane, and it is required to be installed directly above the lane. Nowadays, multi-target radar can detect up to 6 to 8 lanes with one radar, greatly reducing the construction cost of checkpoints. At the same time, the installation method is more flexible, and users can choose to install it on the roadside or on the gantry.

Radar is widely used in the field of intelligent transportation, such as radar speedometers and checkpoint speed capture radars. With the rise of smart cities, traffic flow radar and multi-target radar are gradually becoming popular. As sensors for the eyes of intelligent transportation systems, real-time collection of road traffic conditions is becoming increasingly important for better control of traffic flow. Common solutions include video and radar, with the latter effectively addressing issues such as the impact of video technology during nighttime, rainy, and foggy weather. According to Swiss RFbeam company, the combination of multi-target radar and camera has emerged in the field of intelligent transportation. Radar and camera can display the speed, distance, angle and other information of multiple vehicles on a single photo, effectively monitoring the condition of road vehicles.

In the application of new technologies, sensors play a huge and unique role. In addition to the above-mentioned technical application fields, with the intelligent development of urban road traffic, sensors have been widely used as an essential technology, such as common image sensors, radar sensors, etc.

With the introduction of relevant national laws and regulations and the gradual popularization of the Internet of Things, more sensors will be developed and applied, contributing to the construction of intelligent transportation and smart cities. In the future, sensors will be developed in areas such as intelligence, mobility, miniaturization, integration, and diversification.
