Study on Mode Choice and Vehicle Ownership in a Medium-sized Asian City

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 becomes a useful tool. It is used to capture the behaviours contributing the travel demands, and also to predict expected results of each solution. This paper reviews previous studies on travel demand modelling in motorcycle dominant environments, and discusses the findings. Results of the discussion have shown that there are still large gaps, arguments and doubts found from those previous studies, especially a lack of knowledge about medium-sized urban areas. This can be the inspiration for a new research, as described briefly in the last section of the paper.
