【摘要】：目的開展蘭州市居民交通出行情況調(diào)查,了解其交通出行特點(diǎn),分析相關(guān)交通出行暴露參數(shù),探討其影響因素。方法于2015年7-8月,調(diào)查蘭州市3個區(qū)縣2782名居民交通出行的方式和時間特征。結(jié)果蘭州市居民交通出行方式主要為步行(占77.4%),其次為乘坐機(jī)動車(占47.8%)和騎自行車、摩托車、電動車(占9.0%);蘭州市居民平均每天的交通出行累計時間為60.0 min/d,其中步行40.0 min/d,自行車或電動車40.0 min/d,摩托車30.0 min/d,小轎車60.0 min/d,公交車60.0 min/d。交通出行方式和時間因地區(qū)、性別、年齡、文化程度和職業(yè)而不同,且差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論蘭州市不同地區(qū)、性別、年齡、文化程度和職業(yè)居民的交通出行方式和時間有差異。在開展人群交通出行過程中對空氣污染物的暴露評估和健康風(fēng)險評價時,應(yīng)結(jié)合不同人群的實際交通出行模式選擇合適的參數(shù),以提高評估結(jié)果的準(zhǔn)確性。
[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%). The average daily travel time of Lanzhou residents is 60.0 min/d, in which 40.0 min/d, bicycle walking or 40.0 min/d, motorbike 30.0 min/d, car is 60.0 min/d,. Bus 60.0 min/d. The way and time of transportation travel were different according to region, sex, age, education level and occupation, and the difference was statistically significant (P0.05). 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.
