The paper looks at the current state of development in transportation modelling and tries to identify future developments which are either likely or desirable. It discusses developments in the fields of data modelling, surveying techniques for supply and demand data, traffic assignment and travel forecasting models, microscopic modelling, and user interface.

this article aims at identifying the factors involved in affecting the travel demand to iran. the hypothesis of the research specifies the variable of “domestic social unrest and insecurity” as the most significant obstacle that stands against an expansion of the demand for travel to iran. to test the above hypothesis, first several demand models that have been proposed to study demand for tour...

Massive use of motorcycle is a signature of Eastern-Asia developing countries. This is may be termed a motorcycle dominant environment. Although the use of motorcycles is likely to provide many benefits to the riders, it also produces many serious transport issues for the community. To find out the solution, an understanding of traveller behaviour is necessary. Travel demand modelling then beco...

One of the basic goals of tourism demand modelling is to estimate income and/or price elasticities, which can then be used in developing better informed public and private policies. The focus of econometric studies is to determine the extent to which the data support a particular theory. In reviews of empirical studies on international tourism demand and its determinants, Lim (1999, 2006) argue...

Travel demand models have been providing decision-support for transportation infrastructure planning over the past half-century. However, with limited opportunities for new highway and transit infrastructure in congested areas, “demand-oriented” policy measures (e.g. travel demand management), which allow for more efficient usage of existing road and transit capacity, require improved methods o...

Various methods are currently used in travel demand modelling (TDM), for example, the Four-Step model, which is widely used and is perhaps the most famous one, Discrete Choice Models, Fuzzy Set Theory and the Neural Network Approach. The emergence of these different methods is due to, for instance, different areas having different problems. Hence, a method successfully applied in one area could...

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 ...

mobiTopp is an agent-based travel demand modelling framework designed in a modular fashion, so that exchange of individual modules is easy. This offers the possibility to start with quite simple models and implement the system in practice while at the same time providing the opportunity to develop more sophisticated models for research that can eventually be transferred into practice. Also, pra...
