Problems solved by technology

[0004] The driving conditions of buses are different from those of private cars. During the entire route, as vehicles stop at bus stations and passengers get on and off, the number of passengers on the bus is constantly changing and is not a fixed value, which affects the vehicle The load capacity is not a fixed value, so when using the IVE model to calculate the exhaust emissions, the results obtained have large errors
When calculating VSP in the IVE model established in the past, the load is set as a fixed value, which leads to the calculation error of VSP

Embodiment Construction

[0041] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] A vehicle allocation method based on passenger OD per capita emission calculation model, the specific steps are as follows:

[0043] 1. Determine passenger OD;

[0044] Passenger OD information is obtained through the time t of passengers getting on and off the bus and the bus GPS data G(T, P) at each moment.

[0045]

[0046] 2. Calculate specific power parameters;

[0047] VSP (Specific Power Parameter) parameters have a much higher correlation with the influence of the pollutant emission rate than the vehicle’s speed and acceleration indicators, and the VSP parameters can closely link the vehicle’s instantaneous speed and acceleration data with the vehicle’s emissions. To study the emission characteristics of vehicles under different driving conditions. It is defined as the instantaneous output power of a motor vehicle per unit...

Abstract

Provided is a method for vehicle allocation based on a passenger OD per capita discharge calculation model. Firstly, a bus discharge calculation model based on passenger OD and bus real-time working conditions is provided, an accurate VSP calculated value is obtained, and furthermore, according to localized impact factors and a precision VSP value, an accurate IVE model is obtained. The method allocates vehicles according to the obtained accurate discharge amount.

Description

technical field [0001] The invention relates to a vehicle allocation method based on a passenger OD per capita emission calculation model, which belongs to the field of intelligent transportation. Background technique [0002] Now people's public travel mode is mainly to travel by bus. Reasonable arrangement of this travel mode has become a key factor in controlling pollutant emissions under the premise of ensuring travel. [0003] In order to conduct a reasonable comparative analysis of the exhaust emission characteristics of different types of public transport vehicles, we use the IVE model to analyze vehicle emissions. The calculation of vehicle emissions by the IVE model includes two parts: start-up emissions and driving emissions. The research focuses on motor vehicles Pollutant emission levels under different driving conditions. The model uses the engine specific power VSP (Vehicle Specific Power) parameter to characterize the corresponding relationship between the in...
