As an eco-friendly transportation mode, shared bicycles provide a new option for public transit users in urban areas. China’s bicycle-sharing market began flourishing in July 2016 and reached a plateau in 2017. How shared bicycles influenced public transit systems during this period is an interesting topic. A case study of Beijing is conducted. This study aims to identify the competitive and cooperative influences of shared bicycles on public transit by exploring the changes in public transit trip distances before and after the upsurge in bicycle-sharing. A histogram shifting method is introduced to examine the influences of shared bicycles on public transit services from a travel distance perspective. A spatial correlation of bicycling usage and public transit changes is calculated using units of gridded cell spaces. The results show: (1) overall transit usage continued growing after the shared bicycles market reached a plateau; (2) short public transits within 2 km decreased while transfers within 2 km increased; and (3) the decrease of short transits and increase of transfers within 3 km were spatially highly correlated to the usage of shared bicycles. Hence, the role of bicycle-sharing systems is competitive for existing public transit systems during short trips and cooperative for connecting transits.

This paper focuses on urban planning strategies to adapt cities to the increasing rising of temperatures during summer heat waves. The main target is to investigate which configuration and distribution pattern of green spaces could effectively improve natural cooling of urban environments. Although the benefit that green areas give to natural cooling is well known, this kind of studies has hardly been carried out, especially at an urban scale where it is crucial to define quantities and density of green areas to address open spaces design. To reach this goal, a methodology based on the interpretation of the statistical correlation among temperature, urban parameters and green areas configurational indicators was implemented and applied to the case study of the Municipality of Naples, performing all the analysis in a GIS. Results provide guidelines to improve natural cooling in urban areas adopting the most effective configuration and distribution of green areas within a densely-built context.

Jobs–housing imbalance is a hot topic in urban study and has obtained many results. However, little research has overcome the limits of administrative boundaries in job accessibility measurement and considered differences in job accessibility within multiple commuting circles. Using Baidu location data, this research proposes a new method to measure job accessibility within multiple commuting circles at the grids’ level. Taking the Wuhan metropolitan area as a case study, the results are as follows: (1) Housing and service jobs are concentrated in the central urban areas along the Yangtze River, whereas industrial jobs are scattered throughout suburbs with double centers. The potential competition for job opportunities is fiercer in the city center than in the suburbs. (2) Job accessibility with different levels shows significant circle-like distribution. People with long- or short-distance potential commutes demand to live close to the groups with the same demand. Residents with long-distance commutes demand to live outside of where those with short-distance commutes demand to reside, regardless of whether their commuting demand is for service or industrial jobs. (3) There are three optimization patterns for transit services to increase job accessibility in various areas. These patterns involve areas with inadequate job opportunities, poor transit services to service jobs, and poor transit services to industrial jobs. Developing current transit facilities or new transit alternatives as well as adding extra jobs near housing could improve jobs–housing imbalance in these areas. Findings from this study could guide the allocation of jobs and housing as well as the development of transport to reduce residents’ commuting burdens and promote transportation equity. The method used in this study can be applied to evaluate jobs–housing imbalance from the perspective of the supply in other metropolises.

The Impact

This article explores the mechanisms of urban self-organization and the role of formal institutions in shaping peri-urban areas. A case study of Gaobeidian, a former rural village that is now part of Beijing, examines the mechanisms of change and the interdependent relations between institutions and bottom-up initiatives that drive peri-urban transformations. The paper presents two main contributions: (1) it identifies the differences between government-controlled planning, shared governance, self-governance and self-organization and how these intertwine in urban transformations; (2) it proposes three distinct roles played by institutions in relation to self-organization: triggering, constraining and enabling. The empirical study of this Chinese case will enrich the current debate on planning for self-organizing cities by revealing the impact of, and the various responses to, self-organization dynamics in a hierarchical institutional environment.

This chapter assesses the role of transportation and street environments in people's lives and how reliance on the automobile has shaped the United States and other parts of the world. The century-long evolution into a car-dependent culture has had its benefits in terms of commerce and regional mobility, but has also had devastating effects on people's health and safety. Rather than discuss the negative impacts of cars on air pollution, the chapter focuses on the place-based health impacts of reducing people's reliance on the automobile by increasing the walkability of areas and expanding access to public transit. Younger adults are increasingly ambivalent about whether they should even own a car and are moving to cities in search of more efficient and human-scale mobility options. These options include having access to a street network with safe and efficient pedestrian and bike infrastructures as well as public-transit options. Meanwhile, public officials in numerous cities are talking about the benefits of expanded transit systems and walkable street grids to encourage more active lifestyles and attract tourists, families, and entrepreneurs who are tired of traffic congestion and car commuting and interested in a lively street experience that is not simply seen from behind a windshield. The chapter then highlights case studies showing how new place-based transportation and streetscape changes can be a tool for improving health and safety.

Public transit services should favor space equity, and the concern of this study is how the allocation of public transportation resources corresponds to the needs of transit users. Identifying mismatches between urban transit resources and regular transit users benefits the transportation resource allocation policy. This study introduces a location maximum likelihood estimation method and a cell space collector mechanism to explore distribution differences of regular transit riders and transit stations based on data mining. In Beijing, 5.37 million regular transit users were identified, and their first-morning transit stations were found to be within 2 km from their last transit stations used the day before. As their locations were estimated, differences in ratios of the regular transit riders to residents were found among areas. Most regular transit users were located in the suburban areas of 5–20 km from the center of Beijing, and the spatial distribution of transit stations declined from the center to the peripheral urban areas. This mismatch between public transit services and regular transit riders sheds light on urban transportation policies.

Alternative Means

Car use in modern cities with a well-developed public transit is more sophisticated to explain only through hard factors such as sociodemographic characteristics. In cities, it is especially important to consider motives for car use. Therefore, we examined two modern cities with a high modal share of non-motorized modes and public transit to answer the question: How do the affective and instrumental motives influence car use in such cities? The used data set was collected in Berlin and San Francisco. To investigate the role of motives, we applied an ordered hybrid choice model (OHCM) with a probit kernel. Based on the OHCM we explained more than 14% of the overall heterogeneity and gave further insights to the decision-making process. The affective motive had a strong influence on car use frequency, whereby the instrumental aspects did not matter. Furthermore, an effect resulting from age could not be determined for the affective motives in these cities. Results suggest people are more likely to use cars for affective motives despite the city’s adversities. For these people it is difficult to achieve a shift to alternative means of transport. The only way to intervene here is through regulatory intervention.

The Impact

The election of New Labour in 1997 gave fresh impetus to the regeneration and community engagement agendas, and these are clearly central pillars in the Government's drive for sustainable communities. As major institutions in many towns and cities, universities can potentially play a major role in the development of our urban areas and make a significant contribution to the creation of sustainable communities. This paper examines the contribution of universities to urban regeneration and to local communities in England. Whilst there have been numerous case studies assessing the impact of specific universities on local and regional economies and wider research on the impact of universities on the national economy, there has generally been little attention given to their contribution to wider regeneration aims. Rather than adopting a case study approach, the research has focused on a nationwide survey generating quantitative and qualitative data to assess how universities perceive their role within this wider context, the extent to which they have become involved in such initiatives and possible barriers to such involvement. The research indicates that whilst many universities in England have been involved in regeneration and community initiatives, there is potential for more substantial and influential involvement, which could have significant benefits for the country's deprived areas and communities.
