Governments around the world, especially the developed country are all dedicated in solving the traffic problem, considering it an important concern in the course of economic construction. Currently our country is facing a more complicated situation. In claiming for a full settlement of traffic congestion, China has to develop its public transport and make people change their trip mode. That is to say, making the municipal traffic be the public transport based development mode, supplemented by the private car traveling.
Public transportation system is an important component of the city transportation. Intelligent traffic commanding and humanized management system is the basis of improving the public transportation, it is also an essential means for improving operational efficiency, optimize the dispatching system and business administration, besides, it’s one of the important measures for China to solve its traffic problem and reflects the city’s modern management level.
The rapid development of Wireless communication technology, especially the use of 3G and the rapid development of the next-generation internet Research, deployment and industrialization all provide sufficient conditions for the development of intelligence public transport.
This article mainly researches in developing a city bus routes intelligence enquiry system. This system is designed and tested based on the EasyARM1138 breadboard. In order to perform better dispatching of each task, we adoptμC/OSⅡRTOS as the transplant system. Under the control of the operating system, the inquiry on bus routes, bus stop, City Guide, One-Card information can be realized. It provides intelligence consult for travelers to choose the route and transfer program before traveling, it also provides travelers with Electronic Guide and Dynamic real-time information services, constructing a traveler-oriented comprehensive city traffic information service system which will provide all kinds of traffic and travel services to satisfy the whole society’s demands for traffic information.
The system model realized in this article provides a set of an acceptable formula for the inquiry of city public transport information. With the continuous improvement and expansion of the system function, the city bus routes inquiry system will get affirmation and gain wide application. STM32如何使用LSE时钟
