Embodiment Construction
[0023] The emission of a vehicle varies with its operating characteristics and is restricted by many factors such as acceleration, deceleration, parking time, and starting time. The main components of exhaust gas emitted by automobiles are nitrogen oxides NOx, CO, hydrocarbons HC, CO2, and soot particles PM. The most serious exhaust emission of motor vehicles is that when the vehicle stops and starts or runs very slowly, the probability of incomplete combustion at low speed is higher, resulting in higher CO and HC emissions. As the speed increases, the in-cylinder The improvement of combustion conditions reduces the emission rate of CO\HC, so the road sections with heavy traffic flow or congestion will inevitably lead to high concentration areas of pollutants on both sides of the road. By monitoring the concentration of road exhaust pollution and comparing it with the current traffic flow, the rough traffic operation status of each area or road section can be judged.

The present invention provides a road traffic state determination method. The method comprises the steps of: a step A, acquiring atmospheric pollution data of an area a; a step B, analyzing the content of the automobile exhaust gas in the atmospheric pollution data; and a step C, according to the content of the automobile exhaust gas, determining the road traffic condition of the area a. After thetechnical scheme of the invention is adopted, the road traffic operation situation is indirectly determined according to the environmental pollution data, and compared with the direct monitoring roadtraffic operation situation in the prior art, there is one more way to determine the road traffic operation condition, and the traffic guidance by taking pollution reduction as a target can be used to reduce the city pollution. The city pollution data and the traffic operation state data historical data are correctively accumulated to provide a firm data basis for current or future city pollutionand traffic guidance.
Description
technical field [0001] The invention relates to a road traffic state judging method and a traffic state monitoring center. Background technique [0002] With the rapid economic development, the lives of people in various countries have been significantly improved, which has led to a significant change in the way people travel, and the rapid increase in the number of urban car ownership has caused great pressure in terms of transportation, energy, environment, and safety. Intelligent transportation is a complex system. Due to its characteristics of uncertainty, randomness, and non-linearity, urban traffic problems cannot be solved only by expanding roads, restricting vehicles, and congestion charging to achieve the desired results. [0003] As the premise of traffic control and guidance and the prerequisite for solving the problem of urban traffic congestion, the identification of traffic congestion status is particularly important for its reliability and accuracy. Errors in ...
