On the basis of intelligent transportation, intelligent transportation integrates high-tech IT technologies such as Internet of things, cloud computing, big data and mobile Internet, collects traffic information through high-tech, and provides traffic information services under real-time traffic data. A large number of data processing technologies such as data model and data mining are used to realize the systematicness and real-time of intelligent transportation, the interaction of information exchange and the universality of services.

The exchange and transmission requirements of intelligent transportation information transmission part include: 1. Wide temperature work to adapt to various harsh indoor and outdoor traffic environments; 2. Meet short, medium and long-distance optical fiber transmission, with fast switching, self-healing and link backup; 3. Ultra low delay real-time data forwarding, fast response, high backplane bandwidth and large cache; 4. Stable network performance of equipment; 5. Small equipment volume, many ports, small port delay and small delay jitter; 6. * dual redundant power supply with current protection function and adaptive wide voltage. 7. Low power consumption, green and environmental protection. 8. Good compatibility with other brand equipment.
