In China coast, many cities have faced this problem, the rapid development of urban economy, urban population increased dramatically. The urban road network has not been perfect, more complex traffic environment. These factors determine the quality of transport services as essential travel information. Intelligent traffic system into a municipal traffic the only way to sustainable development.

In the early 20th century, many coastal cities began to draw on the experience of large cities at home and abroad, to proceed with the construction of Urban Intelligent Transportation System. From the traffic control center, street traffic signals intelligence system to the traffic police GPS system, TV monitoring system from the loop to the driver information integrated management system, which makes the municipal traffic engineering measures to establish the basic framework and prototype, in daily life, has been basically travel on to meet the needs of the people.

But the transformation has been limited transport vehicles travel far from satisfying the demand, and the resulting urban congestion problem that is increasingly highlighted. Particularly when the number of major or unexpected events, such as organizing national and provincial events, to take traffic control measures, and run into bad weather, commute time, road congestion, public transportation vehicles waiting less than station and other issues, gave the public a great deal of inconvenience caused by travel.

To this end, in the 2008 Beijing Olympic Games the opportunity, some cities to establish a public transportation bus system intelligent scheduling command center, command centers, the functional orientation is: the total scheduling major events command center, command center for emergencies and daily operations scheduling command center. Although the public transportation system than the past, improvements in efficiency, but the command center bus schedule “smart” role has still not been fully exploited. Therefore, how to further develop and improve the municipal transport system, a People’s Congress, representatives as well as the focus of media attention and discussion. Intelligent transportation system the city building and improvement was also put on the agenda.

2009, some of the city’s municipal public transport sector to introduce intelligent transportation system in China Unicom, for Public Traffic Command Transformation. After transformation of the scheduling command center, hundreds of vehicles on a bus in the vehicle installed GPS, the 50 buses, install a wireless communications device, used for major road transit vehicles, command and dispatch. Car GPS terminal through the GPS positioning, Unicom intelligent transportation system able to locate the coordinates stored in the car after the terminal period, and then combined with the China Unicom SIM card communication module, the location coordinates information data sent through China Unicom’s WCDMA network into the background, and then through the use of GIS (digital map) technology, will coordinate accurate feedback in the control interface; while in a bus video collection terminal, the video data transmitted through the WCDMA network to the monitoring center when emergency occurs, the monitor Centre to real-time processing and scheduling.

GPS Car installed the rescue recovery vehicle to achieve a concentration of aid is to improve the efficiency of the rescue vehicle repair. System features include: request processing, scheduling processing, vehicle graphics control, work order processing, data synchronization.

Meanwhile, China Unicom is also intelligent transportation system bus rapid transit (BRT) system, an important part of maintaining high service levels of its strong security. Unicom intelligent transportation system give full consideration to the operation of large urban advanced public transportation needs of a network, communication, control, computer, information processing and intelligent transportation system technologies to provide efficient and reliable, practical and operational scheduling system, vehicle electronic systems, intelligent system platform, and so on service projects, and gradually realized the BRT’s “human – vehicle – Station – Road” Integration, the bus priority, rational management, rapid up and down, safe and comfortable, human services functions into full play.

In addition, China Unicom’s intelligent transportation system provides an electronic stop sign feature that allows passengers a clear understanding of the optimal travel route, vehicle arrival time information for passengers the best travel services.
