Abstract: Traffic data information is the foundation and prerequisite for the realization of intelligent roads. The outbreak of Corona Virus Disease 2019(COVID-19) has accelerated the development of intelligent transportation and driven the progress of intelligent roads. As a sensing device in the intelligent system, traffic information collection sensors play a non-negligible role in the collection of traffic big data and are the prerequisite guarantee for the realization of various system functions. The research collects relevant information of several traffic data acquisition sensors commonly used in current road systems, such as toroidal coil detectors, image sensors, microwave radar sensors, and geomagnetic sensors. The working principle is briefly described, and its application status and existing problems in intelligent road engineering are analyzed. Finally, the future development trend of traffic information acquisition sensors is discussed. The study found that traffic information acquisition sensors are in a development stage. The future development trend of traffic information collection sensors is to break the monopoly of foreign technologies, develop small, high-sensitivity, durable sensors, and strengthen the integration of multi-sensor technology, so that sensors can be more accurate, lower cost, and more in line with data collection needs.
Key words: Intelligent road; traffic information collection; sensor; working principle; application status
