A modal share (also called mode split, mode-share, or modal split) is the percentage of travelers using a particular type of transportation or number of trips using said type. In freight transportation, this may be measured in mass. Modal share is an important component in developing

Comparability of data

Modal share data is usually obtained by travel surveys, which are often conducted by local governments, using different methodologies. Sampling and interviewing techniques, definitions, the extent of geographical areas and other methodological differences can influence comparability. Most typical surveys refer to the main mode of transport used during trips to work. Surveys covering entire metropolitan areas are preferred over city proper surveys which typically cover only the denser inner city.

Modal split of journeys to work

The following tables present the modal split of journeys to work. Note that it is better to use a measure of all trips on a typical weekday, but journey to work data is more readily available. It would also be beneficial to disaggregate private motor vehicles figures to car driver, car passengers and motorbikes (especially relevant for Asian cities).

Modal share targets

The Charter of Brussels, signed by 36 cities including Brussels, Ghent, Milan, Munich, Seville, Edinburgh, Toulouse, Bordeaux, Gdansk, and Timișoara, commits the signatories to achieve at least 15% of bicycling modal share by 2020, and calls upon European institutions to do likewise. The cycling modal share is strongly associated with the size of local

Modal share in the developing world

The modal share differs considerably depending on each city in the developing world. According to UNECE, the global on-road vehicle fleet is to double by 2050 (from 1,2 billion to 2,5 billion, see introduction), with most future car purchases taking place in developing countries. Some experts even mention that the number of vehicles in developing countries will increase by 4 or 5-fold by 2050 (compared to current car use levels), and that the majority of these will be

Legislation impacting the modal share

Through legislation (i.e. taxing and conditions on new car purchases), ... car ownership can be discouraged. This could help in achieving a modal shift.
