The objective of this paper is to examine whether the use of conventional trip generation models based on cross-sectional data will produce biased results. Panel data are used to control for omitted time invariant household effects. The methodology is based upon fixed and random effects models....

The objective of this paper is to examine reporting errors in panel data obtained from multi-day travel diaries. A distinction is made between within and between wave biases. The former leads to an increase in under-reporting associated with the number of days the diary is kept. The latter is...

The objective of this paper is to present a panel data model of car ownership and mobility. Unobserved heterogeneity is controlled for by including correlated random effects in the equations describing car ownership and mobility. A mass-points approach is adopted to control for unobserved...

Over the past two decades many papers have been published on the impact of Information and Communication Technologies (ICT) on travel behavior, but the literature focusing on the impact of ICT on accessibility is relatively scarce. In this paper we give an overview of the impact of ICT on four...

Option values and non-use values are well-known concepts in environmental economics, but so far there been few attempts to apply the concepts to the transportation field. This paper therefore firstly reviews empirical studies on transport option and non-use values, and secondly examines the...

Current transport models usually do not take motivational factors into account, and if they do, it is only implicitly. This paper presents a modelling approach aimed at explicitly examining the effects of motivational factors on present and future car use in the Netherlands. A car-use...

In 1999 US Congress passed the National Air Quality and Telecommuting Act. This Act established pilot telecommuting programs (Ecommute) in five major US metropolitan areas with the express purpose of studying the feasibility of addressing air quality concerns through telecommuting. The major...

The influence of technological change on industry performances is nowadays being increasingly investigated under the broad category of "national systemic competitiveness". Moreover theoretical works have shown that the relationship between technology and economic performance not only takes...
