Abstract
In this paper, energy dissipation (ED) rate and particulate matter emission (PME) rate were investigated by local measurements between the warning sign and the traffic bottleneck based on a two-lane NaSch cellular automaton model. The aim of this study was to present the variation trend profiles of ED and PME caused by traffic bottleneck with traffic flow states and associate it with particular factors. Factors including the exchange success rate of vehicles on the reduced lane, length of the lane reduction, setting distance of warning sign before the traffic bottleneck, speed limit, and safety distance were discussed in the periodic boundary condition by making comparison with a simulated benchmark case, respectively. Impacts from the injection rates and extinction rate of the lane were also been investigated in the open boundary condition. Results showed that proper location of the warning sign, reasonable speed limit, and keeping downstream uncongested have significant effect on reducing ED and PME.

基于NaSch模型的交通瓶颈能量耗散与颗粒物排放
摘要
在本文中,基于双车道 NaSch 元胞自动机模型,通过对警告标志和交通瓶颈之间的局部测量来研究能量耗散 (ED) 率和颗粒物排放 (PME) 率。本研究的目的是呈现由交通瓶颈引起的 ED 和 PME 的变化趋势剖面与交通流状态,并将其与特定因素相关联。在周期性边界条件下,通过与模拟基准案例的比较,讨论了减少车道上车辆的交换成功率、车道减少长度、交通瓶颈前警告标志设置距离、限速和安全距离等因素。 , 分别。还在开放边界条件下研究了车道的注入速率和消光速率的影响。
