Problems solved by technology

In this method, the selection of covered roads is based on the selection of sensing vehicles. This method does not take into account the importance of each road in the target area, so there is no way to ensure that the key road sections in the road network of the target area can be covered.

Abstract

The patent discloses a method for selecting sensing node based on key road segments in crowd sensing system, and the method comprises the following steps of: step 1, constructing a crowd sensing system; step 2, determining the key road segments; step 3, the cloud platform selecting the key road segments and delivering the sensing task; and step 4, the cloud platform selecting the sensing node based on the key road segments. The invention adopts the crowd sensing technology to monitor the traffic state of the road network, and solves the problem that the installation and maintenance cost of fixed detectors is too high.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation and crowd sensing, in particular to a method for selecting sensing nodes based on key road sections in a crowd sensing system. Background technique [0002] The process of urbanization in China has led to an increase in the number of cars in the country, and the traffic status of the road network has become complicated. In order to ensure that a large number of vehicles can run stably on the road, traffic management personnel often need to use roadside and road surface detection facilities to extract traffic parameters in order to accurately predict the traffic state and complete the traffic control and guidance of road vehicles. However, in the face of the ever-expanding road network scale, the cost of building a complete traditional road traffic detection system is huge, so the maintenance and management of traditional detection equipment is also very difficult. [0003] In o...
