为获取出行者对城市公交的出行信息需求及时空分异特征,以2011—2014年全国31个中心城市的“城市公交”百度指数为数据基础,应用标准差及锡尔系数,对中心城市公交信息关注度的绝对差异和相对差异进行特征分析。然后,构建耦合协调度模型,对中心城市公交信息关注度与城市公交服务水平的协调性进行测度。结果表明,中心城市公交信息关注度的绝对差异在2011—2014年总体呈现扩大趋势,相对差异在空间上总体呈现出发散态势;空间位序变化表现为由东部向中部、西部逐渐递减;中心城市公交信息关注度与城市公交服务水平的空间耦合协调度整体较低,且区域差异性较为显著。
In order to obtain the travel information needs and the spatial and temporal differentiation characteristics of travelers for urban buses, taking the “City Bus” Baidu Index of 31 central cities in China from 2011 to 2014 as the data base, Urban public transport information attention absolute difference and relative difference characteristics analysis. Then, a model of coupling coordination degree is constructed to measure the degree of coordination between the public transportation information in urban centers and the urban public transportation service level. The results show that the absolute difference of public transportation information in central cities shows a general trend of expansion in 2011-2014, while the relative difference shows a general trend of divergence in space. The change of spatial order decreases gradually from east to middle and west. The coordination degree of spatial coupling between public transportation information attention and urban public transportation service level is low, and the regional difference is more significant.
