Random coefficient logit (RCL) models containing random parameters are increasingly used for modelling travel choices. Willingness-to-pay (WTP) measures, such as the value of travel time savings (VTTS) are, in the case ...

Best worst choice response tasks have become increasingly popular as a means of increasing the amount of information captured from respondents undertaking stated preference experiments. In analysis, best worst data is often ...

Stated preference (SP) experiments are becoming an increasingly popular survey methodology for investigating air travel choice behaviour. Nevertheless, some evidence suggests that SP experiments do not mirror decisions ...

Stated choice (SC) studies typically rely on the use of an underlying experimental design to construct the hypothetical choice situations shown to respondents. These designs are constructed by the analyst, with several ...

While a significant literature exists on the generation of experimental designs for stated choice experiments, little work has been done to effectively accommodate constraints on these designs. Constraints may include the ...

The interest in reform of road user charges for freight distribution in many countries continues unabated, linked to a desire to improve economic efficiency as well as recognition of the declining revenue base from ...
