Abstract

The invention relates to a intelligent method for monitoring vehicle flow, wherein the method is based on a magnetoresistive sensor and a ZigBee network. The method is used to solve some problems in urban traffic. According to the invention, vehicle flow in traffic is monitored. And then after data is processed, the data is transmitted to a traffic control department and a communication service provider; on one hand, the obtain data information is further utilized by the traffic control department to lead and control the traffic; on the other hand, the communication service provider utilizes a self-communication network to give guidance to information-demanding users including mobile communication users for their trips. Therefore, people can understand the situation of the amount of the traffic without passing a section of a road; consequently, support is provided for selection of trip routes of the people taking trips, so that it is convenient for the people to go out and an operation of a city becomes more efficient. With utilization of the mobile communication network of the communication service provider and mobile terminal equipment like a mobile phone and a PDA and the like, traffic indication and guidance are provided for people that go out and people that are on the way, so that a traffic jam degree can be reduced, traffic accidents can be avoided, and success rates of handling special events like emergency rescue and disaster rescue can be improved.

Description

technical field

[0001] The present invention is an application system based on wireless sensor network (Wireless Sensor Networks: WSN) technology in traffic flow monitoring. The invention provides initial traffic flow data for solving the congestion problem existing in urban traffic, and is helpful for alleviating increasingly serious urban traffic congestion. Problems provide an important means of solution. The invention belongs to the technical field of Internet of Things. Background technique

[0002] Urban traffic congestion and congestion are becoming more and more serious, and such problems can be described as worldwide problems. Most cities in the world are suffering from traffic congestion to varying degrees, except for a very small number of cities due to developed public transport systems and restrictions on the development of private cars, or due to the small number of urban population and vehicles. It restricts the development of the automobile manufacturing in...
