Mode choice modelling is commonly done to estimate the patronage demand of the various available transport modes. Since the late 1990’s in South Africa, Stated Preference (SP) surveys and occasionally Revealed Preference (RP) surveys have been used to estimate the representative trip utility attributes and their associated weightings. The transit utility attributes and weightings are also used ...

In this paper, we undertake the first examination of the effects of personality on individual economic choices over public environmental goods, using a stated preference approach. Based on three data sets from three separate choice modelling studies, we examine the effects of personality on preferences for the status quo, for changes in environmental quality, and over the costs of investing in ...

One of the important problems studied in the area of travel behavior analysis is travel mode choice which is one of the four crucial steps in transportation demand estimation for urban planning. State of the art models in travel demand modelling can be classified as trip based; tour based; and activity based. In trip based approach, each individual trips is modelled as independent and isolated ...

Previous research suggests that race and ethnicity explain some aspects of travel behavior among the elderly. This paper uses new 1995 Nationwide Personal Transportation Survey location variables based on the size, density, and function of residential areas to question whether the mode choice of White, non-Hispanic elders differs from otherwise comparable ethnic and racial elders when controlli...

ACTION When one brings Occam up, one first must choose between two Occam “actions”: “Do Fit” and “Do Search”. Occam then returns a window specific to the choice made. Search assesses many models either from the full set of all possible models or from various partial subsets of models. Fit examines one model (or a few models) in greater detail. In an exploratory mode, one would do Search first, ...

There is a growing recognition that discrete choice models are capable of providing a more realistic picture of route choice behavior. In particular, influential factors other than travel time that are found to affect the choice of route trigger the application of random utility models in the route choice literature. This paper focuses on path-based, logit-type stochastic route choice models, i...
