Smart transportation makes travel more convenient (new economic direction) | Transportation | Economy
In summer, when going out, open the mobile app to check the "sun protection route"; Driving, navigation software can read seconds to prompt countdown to traffic lights; On congested road sections, the shared bike system can recommend parking spots; At highway intersections, visual recognition technology can achieve non-stop toll collection... From urban transportation to cross city travel, from the "first one kilometer" to the "last one kilometer", information technology is deeply integrated with the transportation industry, and new products and models continue to emerge, optimizing people's travel experience. How can smart transportation help people enjoy their travel and how can it be further promoted? The reporter conducted an interview.
From mobile navigation to intelligent parking, providing better travel services
This summer, when traveling, use mobile map navigation, and the system can display the surrounding shaded and shaded road sections in real time, and automatically plan cool routes according to the destination.
"By using remote sensing technology to intelligently identify the distribution density of trees around the road, and taking into account specific locations and other factors, the dynamic light and shadow conditions of the road section can be calculated." The person in charge of Gaode Map explained that the judgment of the Lou Yin road section is more complex, involving building shape and sunlight angle, etc. Therefore, the team has specially designed a set of dynamic light and shadow tracking algorithms.
The application of mobile intelligent terminal technology enables better and more efficient urban travel services. "There is a peak valley phenomenon in urban travel, with long waiting times for taxis during peak hours," said Li Xinhua, General Manager of Gaode Taxi Business Unit. In order to improve the efficiency of supply and demand matching, the company has developed a "scale system", which uses artificial intelligence big data to predict regional congestion in real time and uses real-time prices as a lever to adjust supply and demand relationships.
Orderly transportation relies on both vehicle scheduling and standardized parking. In the last mile of travel, information technology is assisting in improving the shared bicycle parking experience. "How many cars should be placed at which parking points? Previously, it was all up to the offline team to make on-site decisions, which was not efficient." Huang Binqiang, the head of Meituan Bike Technology Department, introduced that at some morning and evening peak tide points, such as subway station entrances, there would always be too many or insufficient vehicles. By applying deep learning models to predict user needs and intelligently schedule vehicles, it not only facilitates user travel but also makes road traffic more orderly.
From ride hailing to shared bicycles, from travel navigation to intelligent parking... Information technology is integrating into every corner and link of urban transportation, constantly meeting the diverse and differentiated travel needs of the public. According to data from the Ministry of Transport, ride hailing services currently cover more than 300 cities, with a daily order volume exceeding 25 million. A total of 15 million shared bicycles have been launched nationwide, with a daily order volume of over 28 million.
From precise congestion control to vehicle road coordination, traffic management becomes more orderly
The continuous development of smart transportation has improved the travel experience of passengers and made urban operations more orderly.
"The rapid development of the economy and society has given rise to more transportation demand, but problems such as congestion, accidents, and pollution are becoming increasingly apparent." The relevant person in charge of the Science and Technology Department of the Ministry of Transport stated that practice has proven that relying solely on expanding infrastructure scale not only has limited effects, but also faces "hard constraints" such as land and environment. Information technology represented by artificial intelligence can provide new ideas for improving the service capacity of transportation infrastructure.
Managing urban traffic and regulating traffic lights are powerful tools. Beijing Yizhuang is constructing and renovating 332 intelligent intersections, which can analyze and judge vehicle conditions and adjust signal lights in a timely manner. "From the previous' car watching lights' to the current 'car watching lights', the effect of traffic congestion control is significant." According to Nie Yuren, the general manager of Baidu Zhixing Technology Company, the length of vehicle queues has decreased by 30.3% in relevant areas, and the waste of time at green lights has decreased by 18.33%.
The active exploration and continuous innovation in more application scenarios in various regions have continuously refreshed the progress bar of intelligent transportation development.
On the intelligent connected vehicle test road in Xiangyang High tech Zone, Hubei Province, an autonomous driving unmanned minibus is fixedly connecting passengers. Not far away, an autonomous driving sanitation vehicle is performing automatic cleaning operations. The project leader of the Central and Southern Institute of Municipal Government of China introduced that currently, the local autonomous driving operation service has involved more than 140 vehicle networking application scenarios, covering 234 traffic intersections, a two-way mileage of 510 kilometers, and a large-scale urban level vehicle networking application environment of 150 square kilometers.
Gathering comprehensive data on air, rail, public transportation, and water, dynamically monitoring flow information on people, vehicles, and goods, and analyzing traffic congestion, congestion, danger, and complaints from multiple dimensions... In Chengdu, Sichuan, the "traffic brain" supported by wave storage can meet the needs of illegal identification and other applications with hundreds of millions of images every day, helping to improve vehicle control efficiency by nearly 5 times and increase the efficiency of urban traffic flow by about 15%.
"At present, smart transportation has entered the fast lane of development of 'mobile Internet plus+industrialization', and the industry governance and service capacity has been continuously enhanced." The relevant person in charge of the Science and Technology Department of the Ministry of Transport introduced that China has built a national key operating vehicle networking joint control system and a public supervision and service platform for road freight vehicles, which can realize all-weather, remote monitoring of the speed and location of key operating vehicles and trucks of more than 12 tons, and strictly prevent illegal acts such as speeding, fatigue driving, etc; Provincial-level highway network operation management and emergency response platforms have been fully established in Beijing, Shanghai, Jiangsu and other places; The comprehensive transportation and travel big data open cloud platform based on the government enterprise cooperation model is operating in an orderly manner, and the pilot application of transportation and tourism service big data is steadily advancing.
From urban transportation to intercity road network, long-distance driving is safer
With the help of a well connected road network, artificial intelligence technology accelerates the extension from urban transportation to intercity routes, helping highways accelerate towards high-quality development.
"Smart poles" make safety governance more efficient. The car departs from the urban area of Chengdu and enters the Chengyi Expressway. A pole is erected every 800 meters on the isolation strip, integrating various traditional equipment such as cameras and new facilities such as millimeter wave radar to achieve real-time and accurate perception of the road 24 hours a day. "By utilizing new generation information technologies such as artificial intelligence, not only can intelligent and accurate analysis of abnormal events such as speeding, reverse driving, and emergency parking be achieved, but vehicles traveling on highways can also have a 'thousand mile eye' and timely access to beyond line of sight information." Chen Ken, Chairman of Sichuan Digital, said that since the equipment was built and put into operation, the proportion of accidents actively detected based on artificial intelligence alarms has reached 73.8%, and the average time of accidents arriving at the scene has been shortened by nearly 34%.
Smart lights provide a better long-distance driving experience. When you enter the the Taihu Lake Lake Tunnel of Suzhou Wuxi Changzhou Expressway, the dome lights up bright and soft, and the nearby LED starlight dome, like stars twinkling, adds a sense of comfort to long distance driving. It is reported that the the Taihu Lake Lake Tunnel is 10.79km long, and the intelligent stepless dimming system is used along the whole line, which can automatically adjust the lighting brightness according to environmental changes, easing the tension and depression of drivers when driving in a confined space for a long time. In addition, the tunnel covers 5G signals throughout the entire journey, and combined with Beidou positioning, it can also provide passengers with uninterrupted and high-quality internet and navigation services.
"Smart Station" makes supporting services faster. Entering the Zhongneng Chain Changqing Gas Station in Jining, Shandong, the ETC automatically deducts the payment after refueling, saving 3 to 5 minutes compared to traditional methods. Relying on a huge ETC user group of nearly 30 million, accounting for 1/8 of the national total, Shandong Expressway has built an ETC industry ecosystem. Based on the consumption data and traffic trajectories generated by users in different scenarios, data modeling is carried out to construct a multi-dimensional user profile, thereby providing more accurate highway services.
"Through initial exploration and pilot demonstrations, China's development of smart transportation is moving towards a new stage of large-scale and networked promotion and application. Among them, smart highways are generally in parallel with developed countries," said the person in charge of the Comprehensive Planning Department of the Ministry of Transport.
As an important direction for the high-quality development of transportation, smart transportation has broad prospects for development. The person in charge of the Science and Technology Department of the Ministry of Transport stated that in the future, smart transportation will present three characteristics: transportation tools will achieve intelligence and automation, and the accident rate caused by human factors will be greatly reduced; Infrastructure is more flexible and resilient, making it possible to travel safely and reliably around the clock; Traffic management is more efficient, and the network carrying capacity of the system is doubled.
