The Chinese government has launched a digital health code system to detect people potentially exposed to the coronavirus 2019 (COVID-19) disease and to curb its spread. Citizens are required to show the health code on their smartphones when using public transport. However, many seniors are not allowed to use public transport due to their difficulties in obtaining health codes, leading to widespread debates about these unfair events. Traditionally, public perceptions and attitudes toward such unfair events are investigated using analytical methods based on interviews or questionnaires. This study crawled seven-month messages from Sina Weibo, the Chinese version of Twitter, and developed a hybrid approach integrating term-frequency–inverse-document-frequency, latent Dirichlet allocation, and sentiment classification. Results indicate that a rumor about the unfair treatment of elderly travelers triggered public concerns. Primary subjects of concern were the status quo of elderly travelers, the provision of transport services, and unfair event descriptions. Following the government’s responses, people still had negative attitudes toward transport services, while they became more positive about the status quo of elderly travelers. These findings will guide government authorities to explore new forms of automated social control and to improve transport policies in terms of equity and fairness in future pandemics.

Good connectivity and accessibility help to enhance the competitiveness of regions and countries. This research provides a detailed analysis of the connectivity and accessibility of the Chinese railway network. The studied period starts in 1949 and ends in 2017. The research scope covers the railway system of the entire country (except Taiwan, Hong Kong, and Macao). Instead of focusing on main cities as research objects, this paper provides more detailed insights by using counties as the basic research units. The analysis shows that the achieved connectivity has been increasing continuously over the study period. Four accessibility indicators (temporal location indicator, weighted average travel time, daily accessibility, and potential indicator) provide comprehensive and complementary results, indicating that the most accessible cities and units are located in the southeastern part of the Hu line. In addition, higher economic level, or higher population density, is correlated with higher accessibility. Furthermore, the current network exhibits an unbalanced spatial distribution pattern, with an underdeveloped west. All the indicators show that the accessibility of the northwest and southwest regions is the lowest. Based on these conclusions, regional policy-making suggestions can be made to guide a rational railway network expansion and facilitate the equality and sustainable economic development of regions. The future railway system development is suggested to focus more on enhancing inner and inter-region communication in the west of China and attach importance to poverty-stricken counties in support of balanced regional growth and development. The railway development of the eastern regions needs to focus on optimizing the structure of the network as well as reasonably organizing railway routes.

This study used three-tier architecture to analyze the relationship between the highway traffic development difference and the economic development difference in China from 1997 to 2015. Their time distribution and trends of national and regional differences were quantified via both coefficient of variation and Theil index. Furthermore, the highway traffic connectivity was analyzed for each province. The obtained results showed that the difference of highway traffic development was significantly related to the difference of economic development, and poor connectivity of highway traffic was also strongly related to economic disparity. The investment difference of China’s highway infrastructure could be divided into an unstable stage (1997–2010), and a stable stage (2011–2015). The highway traffic development difference could also be divided into two stages (1997–2006 and 2007–2015). Following the construction of central and western regions in around 2006, this difference decreased significantly; however, large differences within region remained. Provinces in the central and western regions have low connectivity and several remote main cities are not connected via high-grade highways. China’s national economic difference has been constantly decreasing; however, the three regions follow different trends. Furthermore, with the development of the central and western regions, between-region economic differences decreased rapidly. To improve the level of regional equalization for highway development, the government should reduce differences between developed and undeveloped provinces for each region and connect remote cities, thus ultimately reducing differences in economic development and promoting a balanced regional development.

Traffic congestion, environmental pollution, energy crisis, and parking problems are getting worse along with the step of urbanization and motorization. Car-sharing rise all over the world, but during development, there are still a lot of obstacles to overcome such as imbalance between supply and demand. Therefore, the logical location of site is precondition for profitability of a company. In this paper, after studying the existing location model theory, we present an optimization approach to site location in one-way and site-based electric car sharing systems. After the correlation analysis, the study proposed the approach based on covering set model aiming at minimizing the construction cost of organization during the expansion period of the car-sharing system. The model can solve the scale of all kinds of stations and location of the sites. Finally, this paper selects a typical area in Fengxian District of Shanghai as an example to demonstrate this model.

Carsharing is one of the effective ways to relieve the problems of traffic jams, parking difficulties, and air pollution. In recent years, the numbers of carsharing services and their members have remarkably increased around the world. The project of electric carsharing in Shanghai, called EVCARD, has also developed rapidly with very large demand and supply. Aiming to determine the optimal locations of future stations of the EVCARD, this research employs a novel method combining the analytic hierarchy process (AHP) and geographical information system (GIS) with big data. Potential users, potential travel demand, potential travel purposes, and distance from existing stations are selected as the decision criteria. A siting decision system is established, consisting of 15 evaluation indicators which are calculated from multi-source data on mobile phones, taxi trajectory, point of interests (POI), and the EVCARD operation. The method of the AHP is used to determine the indicator weights, and the “Spatial Analyst” tool of ArcGIS is adopted to generate the indicator values for every 1 km × 1 km decision unit. Finally, synthetic scores are calculated to evaluate the candidate sites of EVCARD stations. The results of the case study verify the effectiveness of the proposed method, which can provide a more scientific and feasible method for carsharing operators to site stations, avoiding aimless and random decisions.
