Rapid urban expansion has radically transformed the city centers and the new districts of Chinese cities. Both areas have undergone unique redevelopment and development over the past decades, generating unique urban forms worthy of study. To date, few studies have investigated development patterns and land use intensities at the neighborhood level. The present study aims to fill the gap and compare the densities of different types of developments and the spatial compositions of different commercial uses at the neighborhood level. We captured the attributes of their built environment that support instrumental activities of daily living of 710 neighborhoods centered on the public elementary schools of the entire Shanghai municipality using application programming interfaces provided in Baidu Map services. The 200 m neighborhood provided the best fit to capture the variations of the built environment. Overall, city center neighborhoods had significantly higher residential densities and housed more daily routine destinations than their counterparts in the new districts. Unexpectedly, however, the total length of streets was considerably smaller in city-center neighborhoods, likely reflecting the prominence of the wide multilane vehicular roads surrounding large center city redevelopment projects. The findings point to convergence between the city center’s urban forms and that of the new districts.

Due to the multiple benefits on energy, well-being, comfort, and the economy, the utilization of daylight remains an imperative topic of architectural design. With the remarkable ability of drawing and increasing daylight deep into the core of buildings, atriums with a large proportion of glazing have become one of the most preferred design forms. The concomitant and unexpected visual discomfort in modern buildings, however, has drawn increasing concerns. Therefore, this study investigated the relation between glazing proportion and daylight performance, as well as the impact of building height and atrium types on daylight performance in atrium buildings by using an annual dynamic simulation method and metrics. It was found that extending glazing proportion had prominent effectiveness in the enhancement of daylighting; building height had a negative influence; round and square types of buildings performed much better than rectangular ones. Moreover, to inform a practical design, we analyzed the link between increasing daylight and visual comfort from the perspective of balancing them, and then proposed a design guide for atrium roof-glazing sizing.

This study reviews the transit accessibility concept and describes its empirical application in Richmond, Virginia, USA. The transit accessibility concept involves multiple components. Each component has several measures; the selection of which measure to use depends on unique local circumstances. Geographic Information Systems (GIS) and statistical tools are utilized in this study. It has been found that, although the Greater Richmond Transit Company (GRTC) provides a reasonably good transit service inside Richmond City, its existing hub-and-spoke transit system is not aligned well with new and complex travel patterns (including suburb-to-suburb travel patterns), and thus needs to be restructured in the near future.

This paper examines the different approaches to integrating air and rail technologies and their services at the Shanghai Hongqiao Integrated Transport Hub (“the Hongqiao Hub”) in China. Even though the Hongqiao Hub has the advantage of having both an airport and a railway station located at the same place, its level of air-rail integration remains at a low or moderate level. By analyzing existing air and rail services and potential travel demands, this paper recommends further streamlining the relationships among the Shanghai Airport Authority, the Shanghai Railway Bureau, and airline companies by fostering air-rail integration through the improvement of joint ticketing and code-sharing, direct luggage transfer, the provision of the fast and convenient connection from the Hongqiao International Airport to the Pudong International Airport, and air-rail linkage service area expansion.

This paper uses the Shanghai Hongqiao Integrated Transportation Hub (“the Hongqiao Hub”) as an empirical case to conduct a preliminary node (transportation functional value) and place (urban functional value) analysis. The Hongqiao Hub is the strategic node not only for the Hongqiao Business District (“the Hongqiao Hubtropolis”), but also for the western Shanghai, Shanghai Municipality, and the rest of Yangtze River Delta Region and beyond. This newly emerging “hubtropolis” is a brand new urban form integrating air, rail and other transportation modes as well as urban functions, which is more complicated than single-mode “aerotropolis” urban form in terms of both node functions and place functions. The existing Hongqiao Hub remains as the unbalanced node case, but will become more balanced after the complete construction of the Hongqiao Business District. This study also finds that, even though Bertolini's node-place model provides an important tool, its operationalisation remains a huge challenge.

The Richmond region currently faces very challenging transit and paratransit planning, funding and operating issues. This study proposes and evaluates political, economic, planning and technological strategies based on an analysis of these issues. These strategies could potentially be implemented with different priorities and degrees of obstacles. Ultimately this region deserves an empowered regional transportation authority, which can more effectively generate new transportation revenues, contain transportation expenses, and provide efficient and equitable transportation services. In addition, it is necessary to take a holistic view of these issues and to tackle them in a concerted manner.

This paper conducts a sustainability analysis on the newly opened Wuhan–Guangzhou High-Speed Railway (the Wuhan–Guangzhou Passenger Dedicated Line, or the Wuguang PDL) in China. This analysis focuses on the efficiency and equity aspects of this rail line's direct transportation impacts and indirect nontransportation impacts. The Wuguang PDL has significant transportation and nontransportation impacts on the cities and megaregions along the line. However, it still has generated geographic and social inequity issues yet to be addressed. Due to the opening of the Wuguang PDL, Hubei, Hunan, and Guangdong Provinces, along with the Wuhan, Changsha, and Pearl River Delta megaregions, will be more closely integrated with synergistic effects, although the benefits are still distributed unevenly across different regions.

This paper assesses the impacts of high speed rail (HSR) development in the Yangtze River Delta (YRD) Megaregion, China. After giving an introduction and conducting a literature review, the paper proposes a pole-axis-network system (PANS) model guiding the entire study. On the one hand, the HSR projects in the YRD Megaregion are expected to generate significant efficiency-related transportation and non-transportation benefits. As a result, the spillover effects from Shanghai and other major cities (poles) will greatly promote the urban and regional developments along the major HSR corridors (axes), and the entire megaregion will become more integrated economically, socially, and culturally. But, on the other hand, the HSR projects will also create serious social and geographic inequity issues, which need to be addressed as soon as possible in a proper way. This empirical study confirms the PANS model proposed.

This paper conducts a statistical analysis of student travel behavior at Virginia Commonwealth University (VCU). The data source is the ‘University NHTS’ project launched by the Virginia Department of Transportation (VDOT) in 2009. Through this empirical study, it has been found that university student travel behavior is different from that of the general population; urban universities have lower percentages of nonmotorized trips than college-town universities; undergraduate students are likely to make more daily trips than graduate students – similarly, on-campus students make more frequent trips than off-campus students; the most frequent student activities are home and academic activities; and student group categories have virtually no impact on daily activity profiles, though activity types do have a dramatic impact on daily activity profiles. Based on these research findings, the paper makes a series of recommendations regarding trip generation, trip distribution, mode choice, and activity-based modeling.

At present, customized subarea models have been widely used in local transportation planning throughout the USA. A subarea model's biggest strengths lie in its more detailed and accurate modeling outputs which better meet local planning requirements. In addition, a subarea model can substantially reduce database size and model running time. In spite of these advantages, subarea models remain quite weak in modeling transit projects, smart growth measures, air quality conformity, and other areas. In addition to evaluating subarea models, this paper uses the Irvine Transportation Analysis Model (ITAM) as an empirical case of subarea model to illustrate the remedial procedures in maintaining its consistency with the regional model of the Orange County Transportation Analysis Model (OCTAM). Looking into the future, subarea models face both opportunities and challenges. More GIS applications, travel surveys, micro-simulation software utilization, and modeling improvements are expected to be incorporated into the subarea modeling process.

This study probes into the governing issues centering around the water use dispute and resolution between Richmond City and Henrico County in the Greater Richmond area, Virginia. For a variety of reasons, Richmond City strongly opposed the initiative by Henrico County to construct and operate its own water treatment plant in 1987. As a result of rigorous multi-party planning, mediation, and negotiation processes, Richmond City and Henrico County finally reached a compromise settlement in 1994. This study concludes that mediating and resolving public policy disputes between localities within the metropolitan area is a highly complicated and politically charged process, which can involve different levels of government, business community elites, and other stakeholders; driven by their common interests, the public-private intersectoral boundaries are increasingly blurred; and a planning process blends both political and technical factors together. In this case, the Henrico County's newly proposed water treatment plant project was environmentally cleared by the Water Review Panel's technical report.

Despite constant progress, cancer remains the second leading cause of death in the United States. The ability of tumors to metastasize is central to this dilemma, as many studies demonstrate successful treatment correlating to diagnosis prior to cancer spread. Hence a better understanding of cancer invasiveness and metastasis could provide critical insight.

This article examines key governing issues related to Los Angeles transit operations. The study uses empirical data from the National Transit Database and personal interviews conducted with transit agency officials. Based on technical analysis and evaluation, the authors call for empowering council of governments and small cities to address interagency/intersector coordination and political equity issues, downsizing the Los Angeles County Metropolitan Transportation Authority Headquarters and strengthening autonomy of the “Service Sectors” to better streamline transit operation issues, abolishing small municipal transit operators to refine bus fleet size distribution, and enhancing transit service privatization to yield a better cost efficiency.
