After nearly a year of exploration and practice,Jiangsu transportation industry has formed a number of replicable and promotable achievements in the application of 5g integration,intelligent highway,port,airport,vehicle road collaborative automatic driving,etc.
Road intelligent heating,road not closed in snow and fog
Smart highway construction is an important way to improve the efficiency,safety and service level of traditional highway.
In May this year,Wufengshan,the first new eight Lane Expressway in Jiangsu Province,passed the evaluation of seven experts,including Zhong Zhihua,academician of the Chinese Academy of engineering,Zhou Wei,chairman of the expert committee of the Ministry of transport.
Wufengshan expressway will be built into a model of new smart expressway.At present,a number of smart application scenarios are under construction,and it is planned to be fully implemented by the end of May 2021."Intelligent heating deicing and snow removal on the road surface and safe driving guidance of the lane will realize no road closure in snow and fog days.Through intelligent linkage,ramp flow control,etc.,it can also quickly respond to and process real-time traffic events,and realize digital and intelligent traffic control in the whole process."Chen Shengwu,director of the comprehensive planning department of the Provincial Bureau of communications and construction,introduced that as the first intelligent transportation vehicle road coordination system under the open environment of eight Lane expressway,Wufengshan expressway will also support automatic driving function,and realize on-site real vehicle test of several modes of vehicle road collaborative automatic driving such as passenger cars and heavy-duty trucks.
The Taihu tunnel of Suzhou Wuxi Changzhou Expressway under construction is 10.79 km long and will be built into a"future smart tunnel".
"Suzhou Wuxi Changzhou smart tunnel has been gradually carried out in the future.After completion in November 2021,it will aggregate"digital tunnel"+"intelligent technology"to reflect the value of Taihu Lake Tunnel by scientific and technological means,and lead the development of tunnel engineering management level in the province to a higher level."Chen Shengwu introduced,including the tunnel full transparent panel active luminous signs,showing different pictures,which can improve the driver's attention and relieve the pressure.The tunnel emergency system can transmit the real-time video back to the rescue vehicle terminal through 5g,so that the rescue personnel can understand the scene situation and formulate the rescue plan.
Changtai Yangtze River Bridge is the first river crossing bridge integrating expressway,ordinary highway and railway in China.It will also be built into"future wisdom bridge",which is being implemented on schedule.Chen Shengwu said that the fully digital Changtai bridge will realize all factor perception,all-weather operation and all-round service,making travel smarter and building,management and maintenance more intelligent.
The design daily flow of the eight Lane Shanghai Nanjing Expressway is 115000 vehicles.At present,the daily average traffic volume of the whole line is 120000 vehicles,including 150000 vehicles in the east section and 270000 vehicles in the peak day."Roads do not have the conditions for large-scale engineering expansion.With the arrival of a new era of intelligent and high-speed development and construction,we are trying to build a highway perception system."Yang dengsong,executive deputy director of Nanjing Shanghai Expressway Operation Management Center,introduced that the 42 kilometer demonstration area of Shanghai Nanjing Expressway intelligent high-speed new infrastructure project includes 183 sets of millimeter wave radar equipment,75 sets of high-definition monitoring cameras,8 sets of main line bayonet and other system equipment,3 sets of data analysis and decision-making platform,and more than 300g of multi-source sensing data every day Special lanes for truck automatic driving,Lane active management and control system,vehicle road collaborative cloud control platform,etc.can realize intelligent travel on expressways."
Suzhou takes the lead in driverless public transportation
Recently,Huaian driverless tram has entered the test sprint stage.
On the afternoon of December 2,the reporter tried to take an unmanned tram test car on Sanya road in Huai'an,and all the way to Grand Theater station.During the 1.4 km unmanned driving experience,the tram realized automatic driving,automatic parking and automatic bifurcation.Liang Xiao,deputy chief engineer of Suzhou Fuxin Intelligent Control Co.,Ltd.,introduced that 10 groups of different types of sensors were installed on the front of the car,including radar,camera,speed measurement,distance measurement,positioning equipment,etc.,so that the tram can sense the situation as far as 200 meters away.
In Xiangcheng District of Suzhou,8.4km 5g demonstration road has been built in the central area of high-speed rail new city.Meanwhile,55 km of 5g intelligent network connection road phase II is under construction,covering 16 roads,focusing on building 35 smart intersections.It is estimated that more than 400 sets of intelligent network connection equipment will be deployed.Now it has opened five kinds of commercial scenes,such as sanitation,taxi and public transportation.Among them,intelligent sanitation vehicles and pedestrian free vehicles have been put into operation,automatic driving minibuses have provided the public with normal experience lines,and the first 5g automatic driving taxi connection trial ride in the province has been opened to the public.
On December 3,near the North Station of Suzhou high-speed railway,reporters and several citizens of Suzhou boarded a"canoe unmanned minibus".The safety guard in the driver's seat"took off the handle".The minibus drove automatically and ran smoothly."5G+automatic driving system allows the car to look at the road itself,avoid it and change its path along the track."The safety officer said that the bus line set up on the open road is the first 5g unmanned bus line with normal operation in China,which has attracted the attention of many citizens since it was put on the road.
