48-510: A sustainable transport system: Supporting economic growth in a low carbon economy'. The aim of the NATA Refresh consultation document is to seek views on how NATA should be developed. The methods for assessing the value for money of transport projects have been at the forefront of project appraisal practice in the UK for many years. NATA was designed to build on that good practice by bringing together

72-458: A web based set of Transport Analysis Guidance (commonly referred to as WebTAG ) based on NATA principles, was launched by the Department for Transport (DfT). A further development of NATA has been its use of an approach that disaggregates impacts between all those who are affected by a proposal, rather than the traditional cost–benefit approach of simply assessing the net impacts on society. While

96-778: Is appropriate because the value of working time (i.e., time spent traveling in the course of work) is calculated differently from the value of non-working time (i.e., time spent traveling outside work). For example, if a worker on a salary of £20 per hour travels to a meeting, the value of time in that case is £20 per hour, because that is the amount the employer would be willing to pay to reduce travel time (as travel time can be considered to be "wasted", i.e., not spent working). In practice, time spent traveling on certain modes (especially train , but also bus and car passengers) can sometimes be used to carry out some work, while time spent using certain other modes (especially car drivers, cyclists, and walkers) cannot be used to carry out work. Thus,

120-503: Is different from Wikidata All article disambiguation pages All disambiguation pages Value of time One of the main justifications for transport improvements is the amount of time that travelers will save. Using a set of values of time, the economic benefits of a transport project can be quantified in order to compare them to the costs (thus forming the basis of cost-benefit analysis ). In particular, savings (or, for that matter, increases) in travel time form part of

144-420: The actual value of time from a pair of choices means that hypothetical situations are generally used (the stated preference technique) to deduce values of time. The value of non-working time is linked strongly to utility theory. The value of time cannot be assumed constant over time. Time is a limited good and as productivity and income increase, the relative value of time increases as well. Historically,

168-465: The value of time and vehicle operating costs. A UK Government Multi-Criteria Analysis (MCA) manual, originally produced by the former Department for Transport, Local Government and the Regions and now overseen by the Department for Communities and Local Government , highlights NATA as an example of MCA being applied in practice to a major area of UK Government policy. For those transport matters that are

192-557: The Coalition Government decided that the term NATA would no longer be used. However, the principles and key elements of the NATA framework remain in the Department for Transport 's Transport Analysis Guidance (TAG). NATA was introduced by the then Department for Transport, Environment and the Regions as part of the 1998 Integrated Transport White Paper and first used in the 1998 review of trunk road schemes. Its development reflected

216-505: The NATA framework, the impacts of transport projects are categorised in terms of five high level criteria (economy, safety, environment, accessibility and integration), reflecting the Government's objectives for transport. Each of these criteria are divided into a number of sub-criteria and it is against each of these sub-criteria that the impacts of a proposal are assessed and presented in a 1 page Appraisal Summary Table (AST). The division of

240-459: The average value of time for infrastructure projects at 50% of the wage rate. Recent experimental research across the US suggests that this value should be 75%. This is time spent outside our work, which might include journeys to and from work and leisure journeys. Since this time is not valued in a market, it can only be estimated from revealed preference or stated preference analysis techniques, where

264-494: The change in consumer surplus for a transport project. Values of time are used to calculate the non- monetary costs incurred as part of a journey, so that the generalized cost of the journey (a combination of both monetary and non-monetary costs) can be calculated. The value of time varies considerably from person to person and depends upon the purpose of the journey, but it can generally be divided into two sets of valuations: working time and non-working time . This division

288-642: The decisions made by Ministers in respect of the road schemes were statistically significant in terms of how they related to the information about the schemes included on the ASTs. This demonstrated that Ministers were taking account of the information provided on the ASTs in a consistent way. On 30 October 2007, the DfT published a consultation document – The NATA Refresh: Reviewing the New Approach to Appraisal – alongside, and as part of, its new transport strategy document 'Towards

312-668: The development of its NATA-based transport appraisal guidance, WelTAG, and published its guidance in June 2008. [1] The appraisal procedure used by the Roads Service in Northern Ireland 's Department for Regional Development is based on the five NATA criteria. A transport project evaluation toolkit prepared in 2003 for the World Bank and a series of Economic Evaluation Notes prepared for Bank staff in 2005 drew heavily on many elements within

336-435: The elasticity should be, and from a theoretical standpoint there is no reason why the income elasticity for private travel should be unity, since it is a matter of personal preference how individuals or households allocate additional income to purchasing time savings. Vickerman, R.W. 1975 The Economics of Leisure and Recreation, London:Macmillan New Approach to Appraisal The New Approach to Appraisal (also NATA )

360-493: The five criteria is shown below: The NATA framework is now a cornerstone of UK transport appraisal practice. It has been applied to other types of road proposals, including small Highways Agency projects and local authority road schemes and to other modes of transport, including the major programme of Multi-Modal Studies, initiated by the Government, that were carried out between 1999 and 2003, Local Transport Plan major public transport schemes, as well as rail proposals. In 2003,

384-428: The mass of detailed appraisal information about the impacts of a transport proposal, some of which are expressed in monetary terms, some using quantitative measures or some just in qualitative terms. A key aspect of NATA is the use of standard worksheets to collate the large amount of cost–benefit analysis and environmental impact assessment data and then present it in a more concise, consistent and balanced way. Within

408-454: The new Labour Government's aim of providing a more balanced approach to transport appraisals, in terms of both: Accompanying documents to that review list the ASTs for 68 trunk road schemes and provided initial guidance on how NATA was to be applied to transport projects. A subsequent published study by academics at the Institute for Transport Studies (ITS), University of Leeds found that

432-414: The projection of the value of time has been closely linked to personal income growth, which in practical applications is typically approximated by GDP growth. Due to a substantial amount of uncertainty in predicting the relationship between income and the value of time, it is common to apply relatively simple “rule-of-thumb” estimates that are measured as elasticity to income. Generally, it is not clear what

456-485: The real or hypothetical choices of travelers between faster, more expensive modes and slower, cheaper modes can be examined. For example, if a traveler has a choice between a coach which takes six hours and costs £10, or a train which takes four hours and costs £30, we can deduce that if the traveler chooses the train, their value of time is £10 per hour or more (because they are willing to spend at least £20 to save two hours' travel time). The difficulty in narrowing down

480-543: The responsibilities of the Scottish Executive , Welsh Assembly Government and Northern Ireland Assembly , the NATA principles have been adopted by the relevant transport authorities in those countries. Transport Scotland has issued its own transport appraisal guidance, 'Scot-TAG' (Scottish Transport Appraisal Guidance), which draws heavily on NATA. In Summer 2006 the Welsh Assembly Government consulted on

528-570: The two approaches are equivalent at the aggregate level, the NATA approach allows a more detailed analysis to be made of those who gain and those who lose as a result of a proposal. However the NATA approach raises issues regarding the precise definition of the impacts that are included in the numerator and denominator of the Benefit-Cost Ratio . As well as setting out methods for appraising transport proposals, WebTAG contains values that should be used to assess different types of impacts, including

552-694: The value of travel time (and thus the value of travel time reductions) for modes where the employee could carry on doing some work is lower for employees already using any such mode. Conversely, the value of travel time reductions for such modes for employees currently using a mode that does not allow carry out work (and who would switch mode) is larger. The UK Department for Transport calculates average values of time for travel on various modes of transport so that these values can be used to appraise transport projects as part of its New Approach to Appraisal . Some examples are given below in 2002 prices: ∗ Skewed by London wages The US Department for Transport uses

576-522: Was the name given to a multi-criteria decision framework used to appraise transport projects and proposals in the United Kingdom. NATA was built on the well established cost–benefit analysis and environmental impact assessment techniques (such as those contained in the Highways Agency 's Design Manual for Roads and Bridges (DMRB)) for assessing transport projects and proposals. In April 2011
