"If you want to get rich, build roads first." In the hearts of Chinese people, this proverb seems to be a universal truth engraved in the bones and blood of everyone. Since ancient times, road infrastructure has affected the convenience of transportation conditions and is the basic condition that determines whether a region can develop rapidly.

From dirt roads and cement roads to asphalt roads, asphalt roads, and now smart highways, the development of automobile connectivity and autonomous driving has promoted the implementation of new vehicle-road collaborative systems, and has also forced roads to evolve in a more intelligent direction. . What kind of road is called smart? How to build such a road? What is the role of roads in autonomous driving?

Recently, Peng Yao, founder of Shanma Intelligence, said in an exclusive interview with reporters that the essence of traffic is transportation, and roads are the bottom layer to ensure smooth transportation and safety, but it is still at the stage of improving the level of intelligent management. "In the future, smart highways will be like the current subway. There is a signal control system on the road and a driving control system on the car. The two work together to ensure the speed and safety of every driverless driver."

talks about the current situation

empowers the present Infrastructure

improves the level of smart management

"Press the red button and fasten your seat belt." Twenty-five years ago, in the science fiction movie "Men in Black", the fully automated car driven by Will Smith accurately screened traffic The situation and the scene of adjusting the car's driving status are exactly people's imagination of future smart transportation. In Peng Yao's view, to achieve this goal, promoting intelligent road management is an unavoidable link.

"The industry is still in the early stages of understanding what kind of smart highway today is." Peng Yao mentioned that at this stage, the usual way to build a smart highway is to empower the existing road infrastructure with AI capabilities. facility. That is, high-speed monitoring probe equipment and radar equipment can achieve full-time and spatial perception with technical support, and then connect the smart operation, smart management and smart services of the road, making road investment and return, management and service benefits proportional .

On September 7, 2011, the Ministry of Science and Technology issued a notice on the establishment of a research theme project on key technologies for intelligent vehicle-road collaboration in the field of modern transportation technology under the 863 Program. This is the first appearance of the "vehicle-road collaboration" concept at the national level. Subsequently, cameras and other infrastructure were gradually improved on expressways in Sichuan, Jilin, Liaoning, Fujian and other places, basically achieving "one probe per kilometer". Today, with the help of artificial intelligence and cloud computing empowerment, these probes are already playing a role in road event perception.

Peng Yao took accident rescue as an example and said that artificial intelligence can process the data collected by the probe and notify the rescue forces of the specific location of the accident, how many vehicles were involved in the accident, and what kind of rescue tools are needed. This process will be done manually. Completed automatically with intelligent assistance. Compared with the traditional manual alarm method, it can save 15 minutes of rescue time; at the same time, the data generated by the road and rescue can be fed back to the road management and drivers to help them guide and avoid in advance, thereby reducing the spread of accident casualties. , and reduce the occurrence of secondary accidents.

Talk about construction

Avoid duplicate construction of facilities and equipment

Autonomous driving is not the ultimate goal

In recent years, the rise of autonomous driving has led to the "explosion" of vehicle-road collaboration.

From Baidu 's vehicle-road collaboration open source solution, Alibaba Cloud "smart highway" practice, to Tencent 's "vehicle-road collaboration" ecological connector value theory , to Huawei 's Internet of Vehicles platform Ocean Connect... Since the essence of vehicle-road collaboration is the data interaction between the "vehicle end" and the "roadside", the smart highway track has also attracted domestic giants to compete collectively.

"New energy vehicles are only the first half of the smart car industry. The real second half is smart driving and smart road collaboration." Talking about the key to industry competition, Peng Yao believes that to build a good smart highway, not only do manufacturers need to have deep knowledge Software technology accumulation; more importantly, the ability to avoid duplication of construction as much as possible while implementing smart devices.

The key to avoiding duplication of construction is to realize the upgradability of sensing equipment during the process of investing in smart high-speed construction. Taking investment in the construction of sensing capability equipment as an example, Peng Yao mentioned that the best strategy is to refine the device's ability to sense the road network at the current stage, which can not only meet the current needs for improving management capabilities, but also This ensures that when vehicle-road collaboration is needed in the future, it can be used as a ready-made hardware device as a hardware base. This avoids wasting the need to replace new hardware equipment when capabilities need to be upgraded later.

Since the beginning of 2020, ten provinces and cities including Jiangsu, Shandong, Sichuan, and Henan have successively issued local standards for smart highways. Although the standards vary from place to place, in general, building smart highways and achieving vehicle-road coordination and Autonomous driving is an inevitable trend. In this regard, Peng Yao believes that the introduction of standards in various places means that road construction has been upgraded from the original leveling and widening of roads to the stage of intelligence and intelligence; however, intelligence is only the realization of vehicle-road collaboration and autonomous driving. first step. In the near future, vehicle-road collaboration will realize full road network awareness, provide drivers with all-weather lane-level navigation services, and achieve a more reasonable allocation of road resources; autonomous driving is the ultimate stage of vehicle-road collaboration.

However, driverless driving is not the ultimate goal of vehicle-road collaboration. "When smart highways reach their physical extreme, the derivative services generated around smart highways will be another growth pole of the smart transportation sector." Peng Yao predicts that smart transportation can be fully integrated into work and study, life and entertainment, and large passenger flow gathering and distribution scenarios. , the data generated will be extended to intelligent services, which will be a bigger gold mine in the field of pan-intelligent transportation; however, at this stage, the industry will still be deeply involved in the transportation field itself, because transportation runs through these spaces, which is Very critical.
