[Explanation] Traveling on holidays is blocked on the expressway, and people traveling on highways in rainy and foggy weather are restricted. These problems are expected to be completely resolved in the future.
A few days ago, the Hebei Provincial Transportation Planning and Design Institute took more than three years to launch the "Vehicle, Road, Cloud and Network Integrated Smart Highway Solution."
Around this plan, the institute has built the first intelligent high-speed mobile test experience platform in China.
On November 27, the reporter saw at the Intelligent Transportation Research and Development Center of Hebei Transportation Planning and Design Institute in Shijiazhuang that the mobile test experience platform for smart high-speed solutions consists of a minibus test vehicle and two off-road vehicles, which can be used for vehicles. , Car-road, car-cloud information transmission test, complete the matching study of related software and hardware equipment.

On the one hand, the mobile test platform is to ensure the performance and functions of various key technologies, software and hardware of our smart highway solution, for testing and verification; on the other hand, it is a mobile central command platform, which means that the future smart highway ( Development), a single vehicle may manage one road or multiple expressways, which also provides a preliminary solution verification platform for our smart expressway regional management and control center in the future.
[Explanation] According to Li Chunjie, the smart high-speed solution includes four core technologies: radar sensing, active control, vehicle-based feedback, and cloud control.
The mobile central command platform obtains traffic flow status, environmental status and other information in time through roadside sensing devices. The active control system jointly developed with Southeast University will automatically generate dynamic control strategies based on the collected information. In rainy or foggy weather or road congestion, The information board or mobile phone APP will push information to the vehicle. By optimizing the driving route, regulating the driving speed, and combining technical measures such as roadside guidance, the highway is safe and smooth, and quasi all-weather traffic is realized.

For example, the speed of the wiper (in rainy days) represents the amount of rainfall. At this time (the test platform) can accurately tell the road section (vehicle) where I am and what degree of rainfall it is currently on this road section. Traditional weather monitoring covers a large area more accurately, and it can realize a weather judgment at the kilometer level or 100 meters level. This weather judgment is used to control the traffic flow, or it is the most fundamental for the safety of traffic driving. A shift.
[Explanation] According to the staff of the institute, in the process of implementing the plan, the institute and Beijing Institute of Technology have achieved technological innovation and achieved breakthroughs in 1000-meter ultra-range radar technology, breaking the traditional traffic radar’s monitoring range and scanning Restrictions on time, monitoring accuracy, and deployment cost have realized the real-time and continuous tracking of the unique ID of vehicles on the whole road section, and improved the perception of the road network.
[Concurrent] Zhao Qingjie, Director of the Operation and Maintenance R&D Department of Hebei Transportation Planning and Design Institute: This is an over-range radar with a monitoring distance of one kilometer jointly developed by us and Beijing Institute of Technology. It solves the current domestic (highway) monitoring field Pain point problem.
The main monitoring distance of the current domestic radar is about 200 meters. At present, our ultra-range radar (monitoring distance) has reached one kilometer. It has also been deployed in our Xinyuan (high-speed) test site, and the monitoring accuracy has been Reach more than 95%.
[Explanation] According to Li Chunjie, the current smart high-speed solution launched by Hebei is a design plan for the external backbone expressway network of Xiongan New Area. With the completion of the Rongwu Expressway and Jingde Expressway, the plan will be opened next year Implemented in Xiong'an New District.
[Concurrent] Li Chunjie, Director of the Intelligent Transportation Research and Development Center of Hebei Transportation Planning and Design Institute: Currently we have launched the "Car, Road, Cloud and Network Integrated Intelligent High-speed Solution", which is a design plan for the external backbone expressway network in Xiongan New Area. The plan has been verified and consulted by experts and will soon be applied to the Rongwu (new line) and Jingde expressways of our Xiongan (new area) external backbone road network. With the Rongwu (new line) expressway and Jingde expressway next year After the completion and opening to traffic, our "Vehicle, Road, Cloud and Network Integrated Smart High-speed Solution" will be implemented synchronously.
