摘　　要：文章提出了基于实时路况的城市公交出行时空效率分析框架。首先,通过调用互联网地图接口获取小汽车和公交基于早午晚3个时段实时路况的出行时间,并通过公交智能卡数据获取公交出行量;然后,构建一种基于相对时间效率和出行量加权的城市公交出行时空效率评价指数模型;最后,以深圳市为案例进行分析。结果表明:1)公交相对于小汽车的出行时间,在早高峰差异较大,晚高峰差异较小,即在晚高峰有较高的相对时间效率;2)在空间分布上,中心城区公交站点的时空效率指数在3个时间段整体上呈现较大的波动,外围区域高指数的站点以地铁站点为主;3)公交站点的时空效率指数在3个时间段均呈现空间聚集特征,中心城区和外围城区的站点存在不同的聚类特征,中心城区的站点在晚高峰时段公交出行相对效率更高;4)不同类型的公交站点其时空效率指数会有所差异,地铁站点的时空效率指数普遍比公汽站点高。The travel efficiency of public transportation is a key indicator for judging whether the quality of public transportation has developed compared with other modes of transportation,especially private vehicles.The quality of public transportation is also an important reference factor for residents'choices.With the rapid urban expansion and improvement in motorized travel levels,reducing the time difference between private vehicles and public transportation is the key to improving the attractiveness of public transportation.The relative spatiotemporal efficiency is based on the time difference between private vehicles and public transportation,considering the number of passengers.Recently,scholars have shown great interest in relative travel efficiency.However,relevant studies have shown poor real-time performance because of the unavailability of large datasets,which cannot dynamically reflect the characteristics of relative travel efficiency.The spread of big data and internet maps enables us to perform systematic efficiency evaluations.The internet map incorporates various travel-related information such as travel route,time,and cost under different travel modes based on real-time road conditions and provides access to the extracted embedded travel information.This study proposes a framework for evaluating the spatiotemporal efficiency of different travel modes based on real-time road conditions in Shenzhen.First,travel time data were obtained using an internet map during the morning,afternoon,and evening rush hours.The passenger flow volume was computed using smart card data.We then constructed an evaluation index model of spatiotemporal efficiency based on the relative time efficiency and weighted passenger flow volume.Finally,the results highlighted the following:1)the relative time efficiency of public transportation was higher during the evening rush hours than in the morning.The main reason was the increase in private vehicle travel time during the evening rush hours,reflecting the complexity of urban road
