【摘要】：目的开展兰州市居民交通出行情况调查,了解其交通出行特点,分析相关交通出行暴露参数,探讨其影响因素。方法于2015年7-8月,调查兰州市3个区县2782名居民交通出行的方式和时间特征。结果兰州市居民交通出行方式主要为步行(占77.4%),其次为乘坐机动车(占47.8%)和骑自行车、摩托车、电动车(占9.0%);兰州市居民平均每天的交通出行累计时间为60.0 min/d,其中步行40.0 min/d,自行车或电动车40.0 min/d,摩托车30.0 min/d,小轿车60.0 min/d,公交车60.0 min/d。交通出行方式和时间因地区、性别、年龄、文化程度和职业而不同,且差异有统计学意义(P0.05)。结论兰州市不同地区、性别、年龄、文化程度和职业居民的交通出行方式和时间有差异。在开展人群交通出行过程中对空气污染物的暴露评估和健康风险评价时,应结合不同人群的实际交通出行模式选择合适的参数,以提高评估结果的准确性。
[Abstract]:Objective to investigate the traffic travel status of residents in Lanzhou City, to understand the characteristics of traffic travel, to analyze the related exposure parameters of traffic trip and to explore the influencing factors. Methods from July to August, 2015, 2782 residents in three districts and counties of Lanzhou were investigated for their travel patterns and time characteristics. Results the main modes of transportation and travel in Lanzhou were walking (77.4%), motor vehicles (47.8%) and bicycles, motorcycles and electric vehicles (9.0%).

Conclusion there are differences in different areas, sex, age, education level and transportation mode and time of professional residents in Lanzhou. In order to improve the accuracy of the assessment results, it is necessary to select appropriate parameters for the assessment of exposure to air pollutants and health risk assessment in the course of traffic travel in different population groups in order to improve the accuracy of the assessment results.
