Reductions in railway infrastructure and operating costs, through efficiency gains, deliver benefits to taxpayers (via lower subsidies) and/or passengers (via lower fares). Research undertaken by the Institute for Transport Studies (ITS) at the University of Leeds from 2005 onwards revealed a 37% efficiency gap in relation to rail infrastructure costs and operations, relative to international best practice. The key impact of this research was to inform the Office of Rail Regulation's (ORR) setting, in 2008, of annual efficiency targets for Network Rail for the subsequent five-year period, resulting in a reduction in costs from £18.2bn to £15.8bn over the five year regulatory `control period' starting 2009/10. A secondary impact of the ITS Leeds research was to provide key benchmarking and evidence in more recent ORR efficiency assessments (2010) and Sir Roy McNulty's long-term policy-setting Rail Value for Money (VfM) study (2011). Extending the reach of these research impacts, the water and sewerage regulator OFWAT has, from 2013, adopted the ITS Leeds approach for its latest periodic review.
Research undertaken by the Institute for Transport Studies (ITS) at the University of Leeds from 1995 to 2012 has demonstrated that in-vehicle intelligent speed adaption (ISA) - technology to discourage or restrict speeding - reduces drivers' propensity to speed and consequently can dramatically reduce injury and fatality risk. ITS Leeds research has also shown the environmental benefits of these systems and their high acceptance by users and the public. This evidence has led policy-makers at national, European and international levels to advocate ISA adoption. A key impact has been Euro NCAP's decision in 2013 - directly informed by the ITS Leeds research - to explicitly recognise ISA within the safety ratings of new cars. To this end, the ITS Leeds research has informed a significant change to European-wide `quasi-regulation' and, through encouragement to car manufacturers, imposed lasting influence on the safety features of new cars.
HDM-4 is the most widely used system for road investment appraisal and decision making, generating improvements in public policies and services. Economic development and road agencies in developing countries are major users of the tool. HDM-4 has become the de facto standard used by the World Bank for its road investment appraisals and has been used to assess more than 200 projects since 2008, with some $29.5bn of World Bank loans, credits or grants drawn-down to fund these. Uptake of the tool has led to the commercial success of HDMGlobal, a consortium which manages the distribution and development of the software under exclusive licence from the World Road Association-PIARC, with revenues of £1.6m generated since 2008. HDM-4 has also been utilised for economic assessment and road systems investment management in the UK.
The impact of the research during the assessment period has been in its contributions to the development of public road safety policy in the UK and in Scotland, particularly affecting young people; the development of ISO standards for safety evaluation; the dissemination of its results to industry and other stakeholders; and public education about the dangers of driver distraction.
Research by Prof Jillian Anable and colleagues in the Centre for Transport Research (CTR) at the University of Aberdeen has made a leading international contribution to a specific approach to sustainable transport planning known as `Smarter Choices' or `soft measures'. These have been used to develop non-coercive transport policies that inform people of their travel choices, and seek to improve services to make these choices feasible.
These measures rely on understanding the processes and mechanisms for people to change their travel behaviour voluntarily in response to locally tailored initiatives using a combination of social marketing, travel planning, information provision and investment in alternative transport infrastructure. The research at Aberdeen has used a combination of methods to assess the potential of Smarter Choices, and has also been used to calculate the expected carbon emissions reductions that would result from different combinations of policy measures. This research has also developed a specific quantitative methodology involving segmenting the population to give a flexible interpretation of behaviour, allowing different policies and messages to be targeted to different groups.
The research has directly influenced English and Scottish transport and climate change agendas, being taken up in policy guidance, evaluation frameworks, new funding mechanisms and the inclusion of Smarter Choices in carbon reduction targets. The research has also been used by several local transport authorities in the UK and mainland Europe and as underpinning evidence by many transport and environment NGO's and community groups.
This research by the University's Transportation Research Group (TRG) has contributed to the development of sustainable road transport networks both in the UK and other leading cities worldwide. In summary:
Methods have been developed to characterise and evaluate the performance of mass transit systems which have then been applied in 60 of the world's major cities. The financial benefit, as quantified by mass transit operators, is in excess of £0.5 Billion between 2003 and 2013. Examples of impact include cost savings for escalator renewal by London Underground (2009-ongoing), influencing fares policy in Hong Kong (2003, 2012) and the adoption of performance measurement systems, developed by Imperial, by Chinese metros (2010-ongoing). This impact has been enabled by the creation and subsequent facilitation of 5 global consortia comprising over 70 metro, suburban rail and urban bus operators.
This case study describes impacts on the professional practice of transport appraisal, and on investment planning at national and local levels, arising from an approach developed over the period 2005-2013 to estimate the Wider Economic Impacts (WEIs) of transport investments. The research instigated an important reform of the UK approach to Cost Benefit Analysis (CBA) and provided key empirical evidence that has been formally incorporated in the UK Department for Transport (DfT) web based CBA guidance (WebTAG) since 2009. Governments and public authorities throughout the world subsequently adopted the models and techniques proposed as decision support tools for infrastructure investment and planning. Since 2007 Imperial staff and their industrial collaborators have applied the approach to approximately 150 Billion US Dollars of international transport investment, and its use and impact are now widespread globally. It is now a standard textbook approach for assessing the WEIs of transport investment. Recent applications of the approach in the UK include the official economic evaluations of CrossRail (2010) and High Speed 2 (2010, 2012).
Joint research by the Logistics Research Centre (LRC) and the Transport Research Laboratory Ltd directly influenced the government's decision in 2008 to allow which categories of longer and heavier vehicles (LHVs) onto UK roads. One category out of seven was recommended. This decision was informed by findings relating to impact on the railfreight business and road infrastructure. The LRC subsequently provided advice on cost/benefit of the excluded category (longer semi-trailers) which contributed to the government's decision in 2011 to undertake a ten year trial of 15.6m and 16.6m trailers on UK roads. In 2010-11 the LRC's research on double-deck vehicles was used by the UK government and Freight Transport Association as evidence for opposition to an EU proposal to limit trailer heights to four metres, a measure which would have imposed a significant economic and environmental penalty on the UK.
