Investigating demand models with more flexible elasticity functions
Models of rail travel demand take one of three generic functional forms: the generalised cost (GC) function where price and the various time variables are combined into a composite term through the use of appropriate values of time; the generalised journey time and fare (GJT-Fare) approach, where the time-related variables are combined into a single term and fare remains separate; and the specification of separate elasticities for all terms, term…
The demand impacts of train punctuality in great britain
This paper updates and extends the systematic review and meta-analysis of Wardman and Batley (Transportation 41:1041–1069, 2014), which hitherto was the most comprehensive study of the impacts of punctuality on passenger rail demand in the literature. Whereas the 2014 paper covered 51 elasticities from 6 studies in Great Britain published between 2003 and 2011, this updated paper adds 11 subsequent British studies yielding a further 201 observati…
The use of recovery time in timetables
Recovery time in the rail industry is the additional time that is included in train timetables over and above the minimum journey time necessary often with the explicit aim of improving punctuality. Recovery time is widely used in railways in a number of countries but prior to this study there has been no investigation of the rail users’ point of view. Perceived recovery time, such as being held outside stations and prolonged stops at stations, m…
The valuation and demand impacts of the worthwhile use of travel time with specific reference to the digital revolution and endogeneity
The research reported here is concerned with how the worthwhile use of travel time might impact on the value of travel time savings (VTTS) and on demand set in the context of the rail travel market in Great Britain. It has long been recognised, in a variety of literature, that improvements in worthwhile activities which will have been delivered by the digital revolution will impact VTTS and demand yet there is surprisingly little reliable evidenc…
Is generalised cost justified in travel demand analysis
Generalised cost (GC) has long been widely used as a measure of the attractiveness of travel alternatives. We argue that its limitations have been forgotten, overlooked or not appreciated, and it is used because ‘it has always been used’. We explore the relationships between GC and its components (price, time, value of time) and their respective demand elasticities and show that the variation of component elasticities over time and space is not c…
The impact of planned disruptions on rail passenger demand
Disruptions to rail journeys are experienced by rail passengers on a daily basis throughout the world, with the impacts on passengers ranging from minimal to major. Such disruptions can be categorised as unplanned (e.g. extreme weather, vandalism, accidental damage to lines and power supplies etc.) or planned engineering-based disruptions. This paper focuses upon the latter, providing a valuable contribution to an area which is largely under rese…
New appraisal values of travel time saving and reliability in Great Britain
This paper provides an overview of the study ‘Provision of market research for value of time savings and reliability’ undertaken by the Arup/ITS Leeds/Accent consortium for the UK Department for Transport (DfT). The paper summarises recommendations for revised national average values of in-vehicle travel time savings, reliability and time-related quality (e.g. crowding and congestion), which were developed using willingness-to-pay (WTP) methods, …
Cost and time damping
There is a significant body of evidence from both disaggregate choice modelling literature and practical travel demand forecasting that the responsiveness to cost and possibly to time diminishes with journey length. This has, in Britain at least, been termed ‘Cost Damping’, and is recognised in guidance issued by the UK Department for Transport. However, the consistency of the effect across modes and data types has not been established. Cost damp…

Modelling Tenants' Choices in the Public Rented Sector
This paper uses a stated preference (SP) approach to examine the potential housing choices of tenants in the UK public housing sector. The paper begins by explaining the policy significance of the choices that such tenants might make if alternative dwellings were offered to them. It then discusses the SP approach in general before explaining the way in which it is used in this study. The results of the SP modelling exercise are presented. These s…
