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 sustainable transport within a city or region. In recent years, many cities have set modal share targets for balanced and sustainable transport modes, particularly 30% of non-motorized (cycling and walking) and 30% of public transport. These goals reflect a desire for a modal shift, or a change between modes, and usually encompasses an increase in the proportion of trips made using sustainable modes.

01Comparability 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. As of 26 August 2025 the reference years in these lists span over two decades, making comparisons problematic, especially given changing population, new transportation infrastructure and the effect of the COVID-19 pandemic, among other factors.

05Legislation impacting the modal share

Legislation can discourage car ownership through, for example, taxation and conditions on new car purchases). This could help in achieving a modal shift.
