Chinanews.com, Beijing, March 2 (Li Jian and Zhang Su) As spring returns to the land, the travel needs of people everywhere have increased, and many people have found that the roads in front of their homes have opened up "green wave belts".

It is known that using the "Beidou High Precision" integrated precise positioning and navigation technology, the map traffic light countdown function has been implemented and continuously upgraded in many cities.

  The reporter recently used the map function to find that when the signal light is about to change, the map voice broadcast will send out a reminder, which is convenient for drivers to slow down in advance.

When the vehicle is about 200 meters away from the intersection, the navigation system will also give a suggested speed range based on the vehicle's driving conditions.

  "There are many accidents at intersections. If there are unexpected situations such as rain and fog, and the vision of the vehicle in front is blocked, the driver may not be able to see the change of the traffic lights ahead, slam on the brakes or fail to start. Stealing lights and running lights may also cause traffic accidents." Baidu The person in charge of the map said in an interview on the 2nd that with the support of "Beidou High Precision" technology, the traffic light countdown function has been further upgraded to support "green light countdown", and they have also upgraded the "green wave speed" function for the whole country.

  The person in charge said that through cooperation with traffic police departments in more than 30 cities, more than 600 "urban green wave belts" have been launched nationwide.

This move aims to improve users' driving experience, help relieve traffic pressure and create a safe, orderly and smooth road traffic environment.

  It is known that with the help of technologies such as "Internet + map + information control", many places have successfully practiced it.

For example, in Tianyuan District, Zhuzhou City, Hunan Province, with the "Green Wave Belt" as the core, the congestion index in this area decreased by 13.4%, and the average vehicle speed increased by 9.7%.

  In addition, in Xi'an City, Shaanxi Province, nearly 2,000 "traffic light countdowns" and nearly 200 "green wave belts" have been launched throughout the city, improving the efficiency of citizens' traffic.

  The R&D team stated that it will continue to leverage its technological advantages in the fields of big data, cloud computing and artificial intelligence, and unite all parties to provide safe and efficient travel services for the general public.
