Abstract

Transport accessibility is an important driver of urban growth and key to the sustainable development of cities. This paper presents a simple GIS-based tool developed to allow the rapid analysis of accessibility by different transport modes. Designed to be flexible and use publicly-available data, this tool (built in ArcGIS) uses generalized cost to measure transport costs across networks including monetary and distance components. The utility of the tool is demonstrated on London, UK, showing the differing patterns of accessibility across the city by different modes. It is shown that these patterns can be examined spatially, by accessibility to particular destinations (e.g., employment locations), or as a global measure across a whole city system. A number of future infrastructure scenarios are tested, examining the potential for increasing the use of low-carbon forms of transport. It is shown that private car journeys are still the least cost mode choice in London, but that infrastructure investments can play a part in reducing the cost of more sustainable transport options.

Abstract

The integration of land use planning with other spatially significant policy sectors has been a longstanding aspiration and subject of debate in the planning profession and academia. The strategic planning of the 1960s and 1970s, for example, frequently aimed to promote a more ‘spatialised’ management of public policies and programmes. More recently, in the 1990s and 2000s the notion of ‘spatial planning’, popularised by international debates and new forms of governance and public management, has similarly placed an emphasis on the coherent management and coordination of policies and activities with a spatial impact. Achieving greater coordination between land use and transport policy has been a recurring theme in discussions on the integration of land use planning and other sectors. Informed by the context outlined above, this paper considers integration between land use and transport policies, plans, programmes and projects from both a conceptual and empirical perspective. It postulates the existence of a continuum model of integration between policy sectors ranging from ‘light’ to ‘deep’ integration and identifies barriers to and enablers of the achievement of effective integration. These elements are then used to frame and interpret evidence on the integration of land use and transport policies in Merseyside (UK) between 1965 and 2008. The findings indicate that effective integration is more likely to happen at the centre of a continuum between light and deep integration, with the implication being that deeper integration between policy sectors does not necessarily result in more effective integration overall.

Abstract

There is an increasing concern about the growth of car dependence and its associated negative impacts on cities, including economic and environmental factors, urban form and lifestyle. City authorities worldwide now pay increasing attention to sustainable transport systems by enhancing or introducing public transit services. An example is Riyadh City, Saudi Arabia, which has witnessed a significant growth in car ownership and population. Current efforts to reduce high dependence on private cars in Riyadh involve the development of a new public transport system. Against this background, this paper considers the wider impacts of the new public transport system in Riyadh City on urban form, economics, environment, social norms and culture. The analysis is based on in-depth interviews conducted with transport experts and officials of relevant authorities in Riyadh City. The study results highlight that the city’s urban form would have the highest impact on the uptake of public transport. Moreover, stakeholders assumed that the provision of public transport services in Riyadh would improve mobility, decrease travel time, and create more employment opportunities, positively affecting Riyadh City’s economy and the environment. Interviewees concluded that these potential interventions would affect social norms and culture positively in the long term. Document type: Article

Abstract

Crowdsourcing (geo-) information and participatory GIS are among the current hot topics in research and industry. Various projects are implementing participatory sensing concepts within their workflow in order to benefit from the power of volunteers, and improve their product quality and efficiency. Wheelmap is a crowdsourcing platform where volunteers contribute information about wheelchair-accessible places. This article presents information about the technical framework of Wheelmap, and information on how it could be used in projects dealing with accessibility and/or multimodal transportation.

Abstract

Planning for future energy-efficient and energy-producing buildings requires specific knowledge during the design process. Many design decisions taken by urban planners –form, density, roof type and orientation – have a significant effect on the conditions of such buildings, although urban planners might not always be aware of the effect of their design. This study examines the effects of important design decisions on the solar energy potential of net zero energy solar buildings. Typical Swedish building blocks with varying form, density, roof type and orientation were used to simulate the annual solar irradiation and energy production, and to calculate the load match for heating and electricity under Swedish conditions. Results of this study show that the urban density is the most influential parameter on the solar potential of building blocks. Furthermore, flat roofs often returned the highest load match value, while the effect of orientation on the solar potential turned out not to be that straightforward. With the results of this study, urban planners can make better informed decisions, while it also provides a ground for the net zero energy solar buildings discussion by exposing the boundaries of such buildings in the urban environment.

Abstract

Current mobility patterns mean that many trips cross one or several municipal borders. This emphasises the need to integrate land-use and transport planning at regional functional scales. However, the Swedish planning system is characterised by a ‘municipal planning monopoly’, where local governments control the formal planning instruments. The lack of formal means for regional-level planning has sparked initiatives that can be characterised as soft spaces in planning. The paper analyses how soft space planning as spatial strategy making at regional level is influencing local-level planning. The analysis covers 10 municipalities in the Swedish Region of Skåne. The results illustrate that the dialogue-based process has established a broad consensus on the need to consider the regional scale in municipal planning. However, the results also show that the impact on planning is limited since the consensus-based process resulted in strategic objectives with limited influence on prevailing planning practices. Findings also illustrate that key concepts for operationalising the strategies – including densification and public transport accessibility – were defined and used differently in different municipalities. Consequently, a more stringent use, and stricter definitions, of core concepts could be a way to strengthen the capacity of soft space regional planning.

Abstract

In the context of land use planning, Maryland has attracted significant attention at the national scale for innovative planning efforts. In 1997, Maryland passed a package of legislation collectively referred to as ‘smart growth’. Distinct from earlier regulatory state level attempts to alter development patterns in states like Oregon and Florida, this approach relied on incentives to influence development patterns. This innovative ‘inside/outside’ approach to managing growth relies on targeting state funding to encourage growth and investment in existing urbanized areas and areas planned for development (Priority Funding Areas [PFAs]) while discouraging growth and encouraging the preservation of rural areas (Rural Legacy Areas). Transportation funding for new projects or increased capacity must be directed into PFAs, constituting 85% of total funding on average from 1999 to 2008. Though the statute restricts the expenditure of state funds for transportation outside areas targeted for development, the statutes offer little explicit guidance regarding integrating transportation and land use policies. This article proposes that Smart Growth efforts could be even stronger if land-use policies were integrated more closely with transportation policies. The Maryland Statewide Transportation Model is applied to test the impact of various Smart Growth policies and transportation policies. The paper concludes that Smart Growth could have a bigger impact if transportation policies played a larger role. Document type: Article

Abstract

Transport is a very important part of activities in the tourism sector. In addition to the transport of tourists to and within a destination, transport itself can be a tourist attraction. The aim of this paper is to analyse selected problems of railways in Slovakia (a decrease in the importance of railways for passenger transport in Slovakia in the past 20 years, discontinued passenger transport on certain railway tracks and the modernisation of other tracks, and zero-fare public rail transport services for certain categories of passengers), and to present good examples of the use of narrow-gauge railways for the purposes of tourism (the Tatra Electric Railways and the Kysuce-Orava Forest Railway).

Abstract

Structural disaster damage detection and characterization is one of the oldest remote sensing challenges, and the utility of virtually every type of active and passive sensor deployed on various air- and spaceborne platforms has been assessed. The proliferation and growing sophistication of unmanned aerial vehicles (UAVs) in recent years has opened up many new opportunities for damage mapping, due to the high spatial resolution, the resulting stereo images and derivatives, and the flexibility of the platform. This study provides a comprehensive review of how UAV-based damage mapping has evolved from providing simple descriptive overviews of a disaster science, to more sophisticated texture and segmentation-based approaches, and finally to studies using advanced deep learning approaches, as well as multi-temporal and multi-perspective imagery to provide comprehensive damage descriptions. The paper further reviews studies on the utility of the developed mapping strategies and image processing pipelines for first responders, focusing especially on outcomes of two recent European research projects, RECONASS (Reconstruction and Recovery Planning: Rapid and Continuously Updated Construction Damage, and Related Needs Assessment) and INACHUS (Technological and Methodological Solutions for Integrated Wide Area Situation Awareness and Survivor Localization to Support Search and Rescue Teams). Finally, recent and emerging developments are reviewed, such as recent improvements in machine learning, increasing mapping autonomy, damage mapping in interior, GPS-denied environments, the utility of UAVs for infrastructure mapping and maintenance, as well as the emergence of UAVs with robotic abilities.

Abstract

"jats:p"Relationships between the activities of bus carriers and rail passenger traffic (and the railway offer) are examined in this article. The study was carried out in peripheral areas located at the Polish and Czech borderlands in Lower Silesia province. High quality rail transport generally increases the demand for transport services. Therefore, the proper development of transport offer plays a key role in the functioning of public transport systems, the backbone of which is rail transport. The study also shows that under conditions of transport market deregulation, bus carriers have developed a competitive network which is not complementary to rail transport. As a consequence, the deregulation of the transport market has increased the risk of transport exclusion. Document type: Article
