Road network running condition analysis method based on fuel consumption acquisition

Abstract

The invention provides a road network running condition analysis method based on fuel consumption acquisition. The method comprises the following steps of: step 101) acquiring fuel consumption data of a vehicle; step 102) obtaining behavior types of a driver according to the acquired fuel consumption data, wherein the behavior types of the driver can be classified into vehicle starting and stopping, overtaking and idling; step 103) judging whether a road where the vehicle is positioned is in a congestion state according to whether a congestion prejudging state behavior occurs and the times of the congestion prejudging state behavior that occurs in a set time section T, that is, the road is defined to be in a congestion state when the frequency of the congestion prejudging state behavior that occurs is higher than a set threshold value, otherwise, the road is not congested; and the congestion prejudging state is defined to be a state that the starting and stopping state of a vehicle is between twice idling of the vehicle; or obtaining the total fuel consumption on a section of the road according to an instantaneous fuel consumption value. The scheme provided by the utility model can be further used for grading the congestion states.

Description

technical field [0001] The invention relates to the field of urban road network operation state analysis, in particular to a road network operation state analysis method based on fuel consumption collection data. Background technique [0002] The current method of analyzing the road network operation status is mainly to judge the congestion situation of the road sections that make up the road network. CAN bus of prior art is a kind of field bus, and it is a kind of serial data communication protocol developed by German Bosch Company to solve the data exchange between numerous control and test instruments in modern automobiles, the communication schematic diagram of CAN bus is as follows attached figure 1 shown. [0003] The basic data used in the existing road network operation state analysis methods are mostly road network traffic flow operation parameters. The three basic parameters of road network traffic flow are speed, density and volume. The existing technology fin...
