Crossroad, without traffic light, maintain order without the policeman, but nobody drive the car is worn be like,flow shuttle, strewn at random and orderly, also do not have any traffic accidents. This is intelligent traffic setting of future.
Drop drop gives Liu Xianghong of chief scientist of traffic of wisdom of drop of a vice-president, drop
Recently, the 8th when by contest network of article liaison man holds (2 0 1 9) annual meeting of market of Chinese intelligence traffic is held. Drop drop gave Liu Xianghong of chief scientist of traffic of wisdom of drop of a vice-president, drop to share afore-mentioned intelligent traffic setting. On annual meeting, a Liyun, Beijing east a few fruit that the relevant controller that waits for an enterprise also shared domain of each comfortable intelligence traffic.
Future, nobody drive the car needs long-range monitoring
Liu Xianghong thinks, intelligent traffic of future includes the cloud of the road of intelligent car, intelligence and intelligence to accuse platform. This 3 person etc traffic participator is all-around move in coordination, intelligent cloud accuses platform to be able to calculate the best travel line that gives on road each car from global goniometer, the pedestrian on the road and blame motor vehicle can be detected by real time, inform all round car, nobody drive will avoid automatically let.
He expresses, current, intelligent car still belongs to bicycle intelligence, prospective car will drive of intelligence the infrastructure such as equipment of system, communication. The road of prospective intelligence just is based on no longer (car) discharge detects, can become the object perception that is based on unmanned vehicle to detect, road side still includes communication unit, use at realizing the communication between car and road.
Traditional intelligent traffic laid a lot of detector, especially car discharge detector, future they become need no longer, "Unmanned vehicle of flow can detect as traffic equipment. " but he emphasizes, bicycle intelligence has perception " blind angle " , cannot solve " ghost probe " the problem, perception problem of road net, still need complementary the perceptive equipment with road side.
To solve " ghost probe " problem, drop drop is attempting a solution. Liu Xianghong says, drop drop built the system that route of a car cooperates with in the crossing between 2 one of date buildings, buildings, include photograph wait like unit of head, lidar, communication, can solve " ghost probe " problem. When surroundings of unmanned vehicle scanning, if stopped in the car of roadside to hold off a pedestrian, bring about unmanned vehicle to be able to not detect certainly pedestrian. Right now, the perceptive equipment of road side can feel a pedestrian, inform unmanned vehicle through communication method.
What is the cloud accuses platform? Liu Xianghong says, in actual physical space, the lamp (the perceptive equipment of side of road of generally refer to) the control that represents road side is unit, the car represents means of delivery, they can generate much data, the cloud accuses the platform that platform is standardization of data assemble, data, main function is to accuse the lamp, accuse a car. "Nobody drive car need is held remotely control a system. " his explanation says, nobody drive car itself can encounter unpredictable problem, right now need assures safety through the method of long-range monitoring.
Look in Liu Xianghong, the system such as signal lamp of the wisdom brain that makes now, wisdom, it is the 1.0 version that wisdom cloud controls platform only. Prospective cloud accuses platform to basically solve long-range monitoring, feel in coordination, optimize in coordination wait for a problem.
"Urban cerebra " discover traffic police love
Solve an user to give the company of a problem as, drop drop also obtained a few positive result in intelligent traffic domain.
Liu Xianghong expresses, drop drop is in Sino-US two ground have the development group that drives automatically, basically mix from the own intelligence of bicycle of car route in coordination two respects have intelligence research, and, drop drop was taken in California and Beijing early or late last year drive automatically the qualification that open road checks.
In addition, he still expresses, drop drop will be in last year in August control of signal of trends of Internet of Liuzhou be born optimizes a system. As we have learned, this system can adopt corresponding technology measure, adjust the traffic light time of a city according to car discharge, speed, have the system that block up in order to alleviate. Shed quantity and speed to undertake metrical to the car according to car contrail data for instance, through corresponding technology comprehensive data undertakes an analysis, signal lamp feedbacks crossing circumstance of the analysis later, the time that coordinates each crossing traffic light is embraced with alleviating. Liu Xianghong expresses, from 4 5 in car volume the 10 thousand conditions that add 10 thousand to 5 4 fall, liuzhou car all stops car frequency to drop 4 % , whole town embraces a slow down 7.4 % .
On annual meeting, ceng Zhenyu of general manager of intelligence of data of the cloud in A also shared the relevant intelligent traffic in Hangzhou wisdom city to build. He expresses, cerebra of city of A Liyun E T can detect the problem in Hangzhou traffic, for instance traffic accident, traffic is embraced, retrograde motion, report a policeman in real time. He discloses, of above of Hangzhou traffic 9 5 % alarm the reason " urban cerebra " discovery. Previously, the policeman is passivity answers processing alarm affection, occupy mode through number nowadays, " urban cerebra " mode, the policeman is OK and active discovery, processing alarm affection.
Additional, be aimed at whole town, "Urban cerebra " the moving characteristic that still can understand each car in real time, understand the traffic situation of every crossing, a section of a highway, know whole town liaison man " blood capillary " arrive " aorta " , computation gives whole town to have how many car running, the position that distributing, how many car is in stop condition to wait.
