Large data for urban residents to travel to the road of navigation

Real-time road conditions, peak periods, http://www.aliyun.com/zixun/aggregation/10343.html "> Accidents, road Construction, traffic control, local climate, summer and winter vacations, large-scale activities ... When these data are effectively integrated and developed, the urban traffic status is under control. "Where are you going today?" How do I get there? "If you have difficulty in identifying specific directions, the intelligent system can actively guide and recommend the optimal travel area, time, route and transportation according to your mind." Yesterday, the national "Smooth project" expert Group deputy team leader, Tongji University professor Xiaoguang demonstrated this "intelligent city traffic monitoring, management and service system", told reporters that the future users can rely on the embedded mobile phone system software, enjoy large data age intelligent travel services.
"No matter where you are in the city, if you're looking for a place to eat within a 5-minute drive, shopping, open the mobile phone, in the screen map of the green area to select the destination, the screen will soon generate a blue travel line, the distance between the two, the length of time, fuel consumption, cost, carbon emissions, parking, bus lines and other information everything ... According to the introduction, Xiaoguang team developed this intelligent travel system, the collection of large traffic data include: Through the city car GPS, fixed detectors, surveillance video, such as real-time information collection, accidents, construction, traffic control, such as real-time reporting information, as well as local climate, large-scale activities, public commuting time, Student Summer vacation dates and other information. At present, the system in Nanjing, Hangzhou and other Yangtze River Delta City trial, the urban traffic status discriminant accuracy rate of more than 90%. According to the introduction, it will be opened early next month, the 15th session of the China International Industrial Exposition official debut.
Compared with the traditional traffic monitoring system, this latest research and development of the successful system has a bright spot, that is, for the traveler to provide "active guide" service, according to the traveler's basic intention to actively guide the way to travel, recommend the best travel area, time and route, save time, cost and other costs. For example, if you want to go shopping, eat, determine a certain amount of time, space and planning expenses, the system will immediately prompt: A few minutes out of the quickest, the most suitable to go to the urban areas, which is the most suitable for transportation. Not only for the general public, but also for logistics companies, freight forwarding companies to help select a reasonable transport path.
The traditional traffic monitoring system concentrates on the road section state of the city, "intelligent city traffic monitoring, management and service system" can monitor the traffic in a certain area of city in real time and forecast the trend of traffic flow in the peak period, monitor the traffic change at the road intersection and the expressway exit more microcosmic than the section, and forecast the congestion. " It can also in the accident, urgent need to rescue the key to a show of skill, so that fire engines, ambulances, rescue vehicles, engineering rescue vehicles, police cars, etc. in the shortest possible time to arrive at the rescue scene. In the future, through the road network synergy, the rescue vehicles through the road sections of traffic lights to switch to remind the non-emergency vehicles to avoid to buy time.
