[0015] figure 1 A flow chart of the method for intelligent prediction of road traffic pollution sources provided by the first embodiment of the present invention is shown in . see figure 1 The intelligent prediction method for road traffic pollution sources provided in the first embodiment may include steps S11 to S16.

[0016] In step S11, first traffic flow information and vehicle identification information collected by a first detector within a first time period are acquired, and the first detector is fixedly installed on multiple first-type roads in the city.

[0017] Specifically, the first type of road may include expressways, trunk roads, secondary trunk roads and branch roads of the city. The expressway is completely used for traffic function services, and it is the main road to solve the large-capacity, long-distance, and fast traffic in the city. Trunk roads are arterial roads connecting the main districts of the city, which are the main skeleton of the urban road...

Abstract

The invention discloses a method and system for intelligently predicting road traffic pollution sources, belonging to the field of traffic pollution and environmental monitoring. The method includes: acquiring first traffic flow information and vehicle identification information collected by a first detector within a first time period ; Obtain the second traffic flow information collected by the second detector in the first time period; according to the vehicle identification information and the city's vehicle information database, count the vehicles driving on the first type of road in the first time period According to the first and second traffic flow information and the city's road network structure map, the city's road network traffic flow dynamic information in the first time period is obtained, and thus the forecast The city's traffic flow information in the second time period; use the proportion of vehicle types and the proportion of each vehicle type emission standard, vehicle emission coefficient and the city's traffic flow information in the second time period to calculate the city's emissions in the second time period quantity.

Description

technical field [0001] The invention relates to the fields of traffic pollution and environmental monitoring, in particular to an intelligent prediction method and system for road traffic pollution sources. Background technique [0002] In recent years, the number of motor vehicles has increased sharply, urban traffic congestion and motor vehicle exhaust pollution are very serious, and the air quality in large and medium-sized cities has deteriorated, which has endangered people's physical and mental health and daily life. Motor vehicle exhaust pollution sources have become the primary pollutant for the deterioration of urban air quality. In the prior art, the total amount of exhaust emissions from motor vehicles is mainly measured macroscopically—in terms of space, the city is used as the unit, and in time, the year is the unit. Statically estimating the total amount of motor vehicle exhaust emissions does not have the function of forecasting. Contents of the invention ...
