Abstract: Through the investigation and analysis of bus passengers satisfaction and its influencing factors, the targeted improvement of bus service quality will help to promote the transfer of passengers with cars from small car travel to public transport and improve the bus sharing rate. Taking the public bus in Weinan city as the research object, the bus satisfaction data of 690 passengers with cars were obtained by random sampling survey. The functional relationship between bus satisfaction and individual characteristics of passengers, travel activity characteristics and bus service quality characteristics was established by using the ordered Probit model, and the effect of significant influencing factors on bus satisfaction was quantitatively evaluated by marginal effect analysis. The research results show that gender, daily bus traveling time, waiting time, transfer convenience, travel information service, waiting environment, tick price and bus stop setting are the significant factors that affect the bus satisfaction of passengers with cars. Measures such as improving departure frequency, popularizing bus information prompt system, adjusting bus route setting and tick price can effectively improve the overall satisfaction perception level of bus service of passengers with cars.

摘要： 通过对有车乘客公交满意度及其影响因素的调查分析，有针对性地提高公交服务质量，有助于推动有车乘客从小汽车出行向公共交通转移，提高公交分担率。以渭南市公交为研究对象，通过随机抽样调查获取690个有车乘客的公交满意度数据；应用有序Probit模型建立了公交满意度与乘客个体特征、出行活动特征及公交服务质量属性的函数关系；通过边际效应分析定量评价了显著性影响因素对公交满意度的作用效应。研究结果表明：性别、日乘坐公交车时间、候车时间、换乘便捷度、出行信息服务、候车环境、票价价位、公交车站点设置是影响有车乘客公交服务满意度的显著性因素。通过改善发车班次、推广公交信息提示系统、调整公交线路设置以及票价价位等措施可有效提高有车乘客公交服务整体满意度感知水平。
