The use of geographical information systems to enhance road safety analysis

The use of Geographic Information Systems (GIS) in road safety analysis has increased rapidly in recent years. They have proved to be effective in answering simple accident enquiries and identifying single sites with a high number of accidents; however, this nowhere near represents their full potential. This paper describes a number of additional applications that make use of a GIS and include methods to better identify mistakes in the police accident report forms, improve the selection of routes and areas suitable for remedial treatment, provide additional information on the safety of school based journeys and identify the home location of road accident casualties. These improvements in the quantity and quality of information should lead to a more accurate and efficient selection of engineering measures and road safety campaigns.

Imagineering Mobility: Constructing Utopias for Future Urban Transport

Over the past fifty years a growing body of work has sought to address the problem of planning for transportation in the long-term future through scenario building. Such thinking has generally been restricted to issues concerned with environmental sustainability and the ‘images’ of future transport so created are usually weak in terms of their social sustainability content, either treating social issues superficially, or ignoring them entirely, or even creating images that are socially undesirable. At the same time, there has generally been a marked decrease over the past twenty years in socially oriented Utopian thinking. As a direct result of these two factors, hardly any consideration has been given recently to imagining socially sustainable views of transport in a future utopia. The key underlying aim of this paper is to provide some background thinking about how this lack might be addressed. To do so, it examines concepts about utopia in terms of their form, content, and function, and considers possible reasons for the recent decline in Utopian thinking and their ‘replacement’ by a type of futures-thinking that is referred to as dystopian avoidance. It then examines transport characteristics of Utopian thinking in urban planning in the 20th century and considers various ‘antinomies of transport’ with respect to future Utopias. Based upon the insights gained, the paper comments on two existing ‘practical’ sets of transport-related scenarios in terms of their Utopian and dystopian characteristics. One particular result is that the Utopian aspects of these scenario sets in terms of their social content are relatively weak, in line with the hypothesised recent general decline in (social) Utopian thinking. Various conclusions are made which emphasise the usefulness of Utopian thinking in transport planning, particularly in participatory approaches. It is suggested that three elements of the transport system should be separately ‘utopianised’: The mobility of people and goods; physical aspects that facilitate or inhibit such mobility; and the system of governance with respect to formulating and implementing transport policy.

An Exploration of Household Response to Personal Travel Carbon-Reduction Targets

ABSTRACT Transport is currently responsible for around one-quarter of the total anthropogenic CO2 emissions in the United Kingdom, and this proportion is projected to increase. The transport sector will undoubtedly need to play a significant role in achieving carbon reductions if the government is to meet its ambitious long-term goal of a 60% reduction by 2050. This article examines current carbon use by households for personal land-based transport and considers how feasible it would be to change that use over the period up to 2050 in the United Kingdom. It provides a unique insight into how much and in what way households and individuals may be willing to adapt their transport behavior to achieve carbon reductions. A computer-based transport carbon calculator was developed to investigate the CO2 emissions of individual households from various modes based on travel diary information. This formed the focus of a series of interactive interviews in which participants were asked to consider how their future low carbon transport strategy could look. Views of households on various abatement measures were explored, including technological change in vehicle design or fuel source and behavioral change through, for instance, traffic restraint and investment in public transport. Overall, a 40% reduction in carbon emissions was seen to be feasible through a combination of behavioral change measures and a realistically achievable degree of technological improvement, falling well short of the UK governments goal of a 60% reduction. Through changes in behavior alone, the households involved could only achieve around a 20% cut in carbon emissions —seemingly a threshold beyond which further reductions will be difficult and may necessitate significant lifestyle change.

Moving around the City: Discourses on Walking and Cycling in English Urban Areas

There remains only limited understanding of perceptions of travel behaviour in relation to short journeys in urban areas and, in particular, the perceived role that walking and cycling for personal travel can realistically play in contemporary society. This paper reveals discourses surrounding the practice, performance, identity, conflicts, and visions relating to walking and cycling in English cities. These were derived from a large-scale study that utilised a comprehensive mixed-method approach using both quantitative and qualitative methods. Q methodology was used as an additional tool to investigate subjectivities on walking and cycling in the city in a structured, interpretable format and it is this approach that is the focus of this paper. The paper concludes with a discussion on the implications of these discourses for policy makers interested in encouraging a shift from car use to walking and cycling for short journeys in urban areas.

The Role of Decision Support in the Implementation of “Sustainable Transport” Plans

Improved decision support is deemed essential for the planning and implementation of sustainable transport solutions, but limited evidence exists that decision-relevant information is effectively used for these purposes. This paper applies a framework inspired by research in “knowledge utilization” to examine to what extent various kinds of decision support are used and have become influential in three different planning situations—a local cycle plan in Copenhagen, the Stockholm congestion charging trial and the UK national transport strategy. The results reveal the extensive use of decision support but also the difficulty of unpicking its exact role in each case. Stockholm presented the most successful case, with a mix of academic and experience-based knowledge inputs facilitating understanding and acceptance. The cycle plan example revealed very limited influence of cycling design guidance. The UK national transport strategy fell somewhere in between with evidence of assessment and monitoring of the plans being well bedded in the culture of the organizations involved, but less supportive of sustainability objectives. While decision support and monitoring are clearly relevant, they provide no guarantee for the implementation of sustainable transport solutions.

Raising awareness of transport issues: The potential to bring about behavioural change?

Changes in the directions of transport policy in the UK in the last few years have led to a wider consideration of possible measures to bring about behavioural change, in particular measures which have the potential to reduce car dependence. Among the measures currently being implemented by local authorities are public awareness or travel awareness campaigns. This paper examines the findings of a research project which evaluated a travel awareness scheme in the context of an integrated transport policy. The research project monitored the attitudes, beliefs and intentions of a sample of the residents who had been targeted by the Maidstone Initiative for Sustainable Transport (MIST) implemented by Kent County Council and Maidstone Borough Council. The research project found some remarkably consistent attitudes about car and bus travel over a period of three years, It also found that whilst people seem to be aware of the impact of travel on the environment they do not consider the environmental impact with t...

Personal Transport Emissions within London: Exploring Policy Scenarios and Carbon Reductions Up to 2050

ABSTRACT This research explored the possibility of achieving significant carbon reductions from personal land-based transport using London as a case study. A profile of carbon emissions from personal land-based transport modes was derived using Great Britain National Travel Survey (NTS) data and a range of carbon emissions factors. A carbon calculator provided carbon consumption per trip. NTS survey data were grossed up to national level using Census of Population data. A baseline of carbon emissions, based on equal per capita consumption, was projected to 2050 using estimates of future population. Four future scenarios were developed and tested using this data. These were: (a) based on the London Mayors Climate Change Action Plan; (b) a technology focussed scenario; (c) a personal carbon trading scenario; and (d) a radical walking and cycling scenario. Results suggest that the latter two scenarios have the potential to achieve emissions reductions in excess of 80%, while scenarios (a) and (b) are somewhat weaker, though still achieve substantial reductions in carbon emissions compared to business as usual.

The unmet travel needs of the older population: a review of the literature

ABSTRACT Unmet travel needs can be defined as trips and activities that people need or would like to do more, but for a variety of reasons they are prevented from doing so. This paper provides a critical evaluation of the literature focused on unmet travel needs, with the aim of assessing the scope of existing studies on this topic and better understanding the full context of older people’s mobility. This narrative review identifies how travel needs in later life have been assessed, and the barriers that affect the ability of older people to fulfil these needs. Due to the heterogeneity of older people and differences in research approaches, the analysis of the literature is not conclusive in terms of identifying the real impact of the analysed variables and measures on unrealised mobility. Nevertheless, of the studies analysed, on average at least one-third of older people report unmet travel needs. This situation was found to worsen with age, and women were reported to be more affected than men. The pursuit of leisure, and in particular visiting friends and family, was found to be the activity most associated with unmet travel needs.
