To evaluate the accessibility change and transportation equity, certain cities along the transportation corridor which the successfully operating WuGuang HSR lies in are selected as samples of influenced ones first. Cities’ connection with HSR and their sizes are considered as choosing criteria. Weighted mean travel time and Generalized weighed travel time, which integrated with generalized cost, are both calculated in the two different scenarios to indicate accessibility changes of each city. The two scenarios are with or without the advent of WuGuang HSR. Accessibilities in different scenarios were carefully contrasted. It was found out that there is no significant change in the mean accessibility aspect of the region between the two scenarios. Then transportation equity issue of the transportation corridor is discussed based on the results of Gini coefficient using the data of Passenger Transportation Balance index. Passenger Transportation Balance index is proposed in this article to indicate the how much is one city’s transportation demand satisfied. The research found that cities had HSR stations built-in all attained a more accessibility improvement comparing with the others. And the gap between the accessibilities of the cities along the HSR line and those which are not is relatively wider. However, the equity evaluation using Transportation Balance Gini Coefficient reveals that massive investment in HSR has no potent evidence for equity improvement.展开更多

As for the urbanizing China, do the mainstream planning approaches fail to take equity issues into account? What are outcomes and the potential countermeasures based on Chinese cities' spatial and policy contexts? From the perspective of transportation equity, this article aims to examine the multidimensional effects related to equity concerns of urban transportation planning and policies in China. It suggests that the municipal government should enhance the service level of public transit and efficiently address the inequity issues of transportation systems. The potential measures include: building a multi-modal transit system, linking affordable housing to the transportation system, highlighting the role of non-motorized mode, and offering proper parking spaces around transit stations.展开更多
