Dynamic Traffic Service

People living in cities are accustomed to checking road conditions to avoid traffic jam before departure, and the core technology behind that was developed and launched by NavInfo in 2007. To date, our dynamic traffic services have covered 340+ cities in the Chinese mainland, as well as Hong Kong and Macau regions, serving 10 million+ in-vehicle equipment users, 100 million+ Internet users and 300+ government and corporate users. Definitely, NavInfo is still exploring more forms of dynamic traffic service to boost the safe travel of intelligent driving.



Dynamic Traffic Flow Service

We provide immense traffic flow data to truly present historical and real-time road conditions, and forecast future road conditions precisely, which means to improve the efficiency of traffic operation and optimize mobility experience.
