Embodiment Construction

[0015] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0016] The invention establishes a micro-statistical model of fuel consumption and emission based on VSP, which can make up for the lack of consideration of traffic characteristics in traditional tail gas prediction models, and uses VSP to describe driving behaviors on various types of roads in Beijing through a large amount of measured data. Considering the average length of road sections and the average driving time of road sections in Beijing, the average speed is calculated at intervals of 3 minutes, the VSP distribution of each average speed interval on roads of different grades is established, and the average driving speed of vehicles is combined with the microcosmic instantaneous driving state. Fully reflect the impact of speed on fuel consumption and emissions under different driving conditions. Establish a speed corre...

Abstract

The invention provides a VSP-distribution-based traffic operation data and vehicle emission data coupling method and system. Excavation and analysis are conducted on features of traffic operation data and vehicle emission data, VSP distribution serves as an intervening variable, and a dynamic mapping relation between traffic operation parameters such as traffic flow, the average speed and vehicle running working condition and vehicle emission parameters such as the emission index and the emission factor. By means of the VSP-distribution-based traffic operation data and emission data coupling method and system, the physical significance of vehicle exhaust emission is simplified, and the efficiency and accuracy of traffic emission quantitative evaluation are improved.

Description

【Technical field】 [0001] The invention relates to a method and system for coupling traffic operation and emission data based on VSP distribution. 【Background technique】 [0002] After long-term construction and development, the transportation department and the environmental protection department have formed their own relatively complete data collection and analysis systems, and have obtained a large amount of data. [0003] To study the traffic operation of a region, it is first necessary to conduct a traffic survey to understand the traffic characteristics and development trends of the region. Through the quantitative analysis of traffic operation data, the specific data of various characteristic parameters can be mastered, which can provide a theoretical basis for scientific traffic planning, linear design and traffic management according to specific situations. Common traffic survey methods include Point Method, Along a Length Method, Moving Observe, Short Section Metho...
