The IT giant needed only three years to completely change a road situation in one of the largest megalopolises of China the Cars intended for utilization. Hangzhou. Photo: China Daily CDIC/Reuters Not so long ago of Hangzhou, the city with the population in 10 million people and the size honor about Moscow, was the fifth in the rating of the Chinese cities with the most complicated movement. Now he takes the 57th place, remaining one of the most densely populated megalopolises of China. A system which allowed to achieve such results developers call City Brain — "City Brain". And similar decisions will be used everywhere soon, the Chairman of the Committee on management of development of Alibaba Group technology Wang Jian told CNN: "The cities in China probably face a large number of problems, than in other countries of the world. New technologies, such as Internet, machine learning, give the chance to solve these problems. Cloud computing allows to transfer the power of computers to new level. As a result all cities will use computing opportunities — just as now use electricity". City Brain collects data on traffic from outdoor cameras on all city and from GPS transmitters of cars and buses. On their basis "a city brain" Hangzhou makes the decision on unloading of certain highways for increase in the general speed of movement of all drivers of the city. Mechanics of management — city traffic lights, and not everything, and only one thousand. Whether really by means of clever setup of traffic lights it is possible to improve so passability of roads in the megalopolis? Sergey Ryzhikov the CEO of the Bitrix 24 company "The theory of roads and the transport movement is described by the theory of mass service. For example, the ordinary road can be calculated on 100 thousand cars an hour, but if cars there are 105 thousand, then productivity of the road falls twice, cars begin to interfere with each other. It turns out that the traffic light acts as some kind of regulator, without allowing more cars on the road, than she is able to serve. In this case it was succeeded to use artificial intelligence more precisely to regulate parameters and in real time to operate receipt of cars on the road. In general, surprisingly long traffic lights were not connected to a uniform control system. Or rather, it is, but regulation is carried out in rare intervals". The three-year period of tests of "a city brain" is considered successful both in Alibaba, and in administration of Hangzhou. Last year City Brain established in 7-million Kuala Lumpur, the capital of Malaysia. There are also competing projects: in the fall the system of clever traffic control in the German Wolfsburg began to test Siemens and Volkswagen. Whether we will apply such "городомозг" to Moscow and other Russian million plus cities? There are different opinions. Vladimir Valdin the expert of the interregional association "City and Transport" "Why all these decisions do not work for us, systems, such how "Green wave", very long time ago were still developed for large streets in big cities? All trouble is that at
