Bus station model selection method based on microscopic traffic emission estimation

Abstract

The invention discloses a bus station model selection method based on microscopic traffic emission estimation. The invention relates to the technical field of traffic engineering design. According tothe method, based on VISSIM and CMEM models, oil consumption and emission at urban bus stops are analyzed; and analogue simulation is carried out on the traffic flows of the buses and the social vehicles in different station forms, and the traffic flows are coupled with a tail gas emission and oil consumption model to obtain second-by-second pollutant emission rates, oil consumption rates, total emission factors and oil consumption factors of the buses and the social vehicles in different station forms. According to the invention, the second-by-second pollutant emission rate, the oil consumption rate, the total emission factor and the oil consumption factor of buses and social vehicles under different station forms can be effectively simulated; and a reasonable bus station model selectionscheme considering bus commuting personnel pollution exposure is obtained, so that refined design of urban public transportation is facilitated, the public transportation service level is improved, and convenience is provided for urban bus station model selection.

Description

technical field [0001] The invention relates to the technical field of traffic engineering design, in particular to a bus stop type selection method based on micro-traffic emission estimation. Background technique [0002] Urban public transport is the main carrier of urban passenger transport. Vigorously developing public transport and advocating public transport priority have become important measures to solve traffic problems in the country and major cities. While vigorously developing public transportation, the energy consumption and pollution discharge of public transportation cannot be ignored. Buses, like other cars, emit a large amount of toxic exhaust gases such as carbon monoxide, nitrogen oxides, hydrocarbons, lead dust, etc. The exhaust pollution of public transport vehicles has generally received attention in large and medium-sized cities. Although the proportion of buses in the total number of motor vehicles is not very large, due to the large engine displacem...

Problems solved by technology

When a bus stops at a bus stop, it goes through the process of slowing down to enter the station, loading and unloading passengers at idling speed, and accelerating to leave the station. The complexity leads to frequent changes in the working conditions of the buses, high fuel consumption and emissions. At the same time, other affected traffic flows are slowed down or even congested here, which increases the fuel consumption and exhaust emissions of vehicles.

[0004] In the past platform selection, the optimal design of bus stops was mainly studied from the perspective of station delay time, but there were few studies on the optimal design for reducing fuel consumption and exhaust emissions

When selecting and designing the platform, only the running conditions of the vehicles were considered, and people at the station would be exposed to exhaust gas while waiting for the train. Since the station is close to the roadway, people will inhale a large amount of vehicle exhaust gas in a short period of time, which will affect human health.
