Problems solved by technology

Compared with the traditional network, the sensor network has a higher node failure rate and data loss rate. Data fusion can greatly reduce the redundancy of data, but the loss of the same amount of data may lose more information, so it is relatively reduced. network robustness

Abstract

The invention discloses a sensor-network-based novel intelligent transportation model design method. The method comprises: according to an indicator function, road traffic volume collection, intersection delay time, and vehicle congestion prediction value are calculated to realize intelligent transportation guidance scheduling. According to the invention, the method has the following advantages: the system model is guided and scheduled by using a transportation performance indicator function; with introduction of the indicator function, credibility and guidance of system implementation are improved; and thus the method has the certain study value in realizing sensor-network-based intelligent transportation.

Description

technical field [0001] The invention belongs to the field of intelligent traffic, and relates to a design method of a novel intelligent traffic model based on a sensor network. Background technique [0002] The growth of motor vehicles, population and the development of urbanization make urban traffic congestion increasingly prominent. Traffic congestion not only reduces the efficiency of infrastructure, but also causes air pollution and waste of energy. With the development of information technology, real-time control, and communication network, the intelligent transportation system ITS (Intelligence Transportation System, ITS) has aroused people's extensive attention. Intelligent transportation technology mainly manages traffic through computer technology, network communication technology, distributed information processing and other technologies, so that the traffic system can play a better role, and sensor network technology is one of many intelligent transportation app...
