城市公交站台乘客吸入汽车尾气模型研究

针对公交站台乘客汽车尾气暴露风险,引入吸入量概念,分别对路段中直线、路段中港湾、交叉口直线和交叉口港湾四种公交站台布局类型建立乘客汽车尾气吸入量模型.以南京市鸡鸣寺公交站台为研究对象,运用该吸入量模型,对不同类型公交站台上乘客汽车尾气吸入量进行了研究,研究表明:在相同条件下路段中港湾式公交站台布局环境中乘客尾气吸入量最小;增加公交车辆线路和发车间隔在相同条件下会增加乘客尾气吸入量.本文的研究为城市公交线和公交站台从乘客健康角度进行人性化布局规划提供了决策依据.

Study on the Models of Passenger Breathing in Automobile Exhaust Gases at City Bus Stops

In order to analyze the risk of passenger exposuring to the automobile exhausting gases, we introduced a concept of inhalation, and then outlined four inhalation models for four different layouts of the bus stops, accordingly named as line-stop in section, harbor style-stop in section, line-stop in cross sections and harbor style-stop in cross sections. Next, taking Jiming-temple bus stop as an example, the inhalation models were calculated and analyzed for different stop styles. The results showed that under the same condition,the inhalation model for the harbor style-stop in road section resulted amount of gases, and as the increasing of the interval of buses and the bus ro in ut gases raised, the study provided a new feasible method to making the decision the smallest es the inhaled for designing the city bus routes and the layouts of bus stops form the view point of passenger-health.
