[Explanation] On September 8, 2020 Internet Yuelu Summit opened in Changsha.
Ma Wei, CEO of Changsha Intelligent Driving Research Institute, revealed at the summit that Changsha currently has 3,400 intelligent connected cars on the ground, creating the world's largest connected car application.
An intelligent networked car is a self-driving car that can access the Internet, has multiple sensors, can send and receive signals, sense the surrounding physical environment, and interact with other vehicles or entities.
On April 19, 2020, Baidu Apollo self-driving taxi was fully opened to citizens in Changsha, with an operating area of about 100 square kilometers.
After 11 days, China's first "Smart Bus Line 315" that was put into use was also opened to citizens in Changsha.
On August 31, Hunan's first highway to support autonomous driving opened to traffic in Changsha.
Ma Wei said that the use of assisted driving on open roads has great potential for improving the convenience and effectiveness of urban traffic.
Although Changsha is at the forefront, the launch of autonomous taxis and smart buses still faces the challenge of technological maturity.

How to solve the maturity of technology?
We believe that we cannot rely on deep learning alone, but rely on vehicle-road collaboration, and rely on the road to solve the problem.
This is why 5G Internet of Vehicles is essential to promote intelligent driving. We in Changsha have made a lot of attempts in this regard.
The traditional Internet of Vehicles is mainly used for the purpose of information collection, and their delay is relatively high. The new generation of intelligent network (computing speed) can control the vehicle, and it can intervene in the environment of automatic driving, which greatly improves the landing. Possibility.
[Explanation] Ma Wei said that in the 5G era, the Internet of Vehicles can achieve low latency in the millisecond level of computing speed, and high-definition image acquisition at centimeter level, so as to take over the vehicle and control the braking, lane changing, turning, avoiding and other series of driving actions in real time. .
In 2020, Changsha Intelligent Driving Research Institute cooperated with Xiangjiang New Area to identify the rigidly needed application of active bus priority, and promote the world's largest Internet of Vehicles application.

We in Changsha can use the Internet of Vehicles to control traffic lights throughout the city.
This is a specific explanation, that is, when our buses are approaching the traffic lights, they issue a priority request. The traffic lights are optimized according to the overall situation to let them go. The green light is given priority and the red light is shortened.
If it is said that the bus with priority traffic light has caused advancement and punctuality, each vehicle adds one more passenger, this new ticket revenue, in the country's 670,000 urban buses, there is an increase of nearly 10 billion (yuan) Income, it has specific commercial value.
