为了研究公交信息对出行前交通方式选择的影响,选取了公交出行距离信息、公交车辆位置信息、道路拥堵情况信息和公交换乘信息等四种公共交通信息,通过均匀设计方法,设计四种公共交通信息组合条件下的居民出行交通方式选择意向调查,并通过在湖北襄阳获得的数据,建立了多项Logit模型,定量分析了显著影响因素.研究结果表明,公交信息对出行前方式选择行为的影响比较显著,且不同的公交信息对出行方式选择的影响存在差异,但总体上会增加人们选择公交出行的意愿;对于已购车的出行者,公交信息的影响十分有限,而个人对于公共交通的偏好也会影响其出行方式选择的意向.研究建议,提供更准确和丰富的公交信息服务以增加城市公共交通的吸引力.
To investigate the effects of public transit information on people's pre-trip mode choice, using uniform design method, a stated preference survey is designed with four kinds of public transit information,including transit travel distance, transit vehicle location, road and traffic condition, and transit transfer information. Survey is conducted in Xiangyang, Hubei Province, China. Data are collected and parameters with multinomial Logit model are estimated. The results show that public transit information affects respondents' pre-trip mode choice significantly and strengthens public transit attraction, although effects of different information exists differences. However, there is little effect of public transit information on people who have already own their personal vehicles. Personal preferences of using public transit are also important in mode choices, and better transit information services may attract more people to use public transit.
