About the modal split

Modal split is a key indicator that reflects the impact of the city’s mobility policies. It is essential to monitor how  the  modal  split develops  during  awareness  campaigns,  improvements  of  public  transport, improvements  of  bike  paths  and other transport services.

Source data

The modal split is primarily based on the data provided by the TUMI’s Global Mobility Challenge 2018 Winners and other inspiring cities. Data quality vary according to the source and methodology used in each city. For example, mobility surveys can be based on historical travel surveys extrapolated to the population or a few road sensors.

As such we aim to provide comparable modal split data of cities while continuing to improve the quality of data and acquire more accurate figures. You can compare city data by region or country by clicking the filter menu on the right. For data resources and notes, please refer to the second page and read them carefully. 


Please let us know how you are using the tool and data via email tumi-network@iclei.org. We would love to know what is useful or needed for mobility practitioners. Do you have a good sustainable mobility story in your city? We may be able to feature your city in a case study, so please get in touch.


We're not around right now. But you can send us an email and we'll get back to you, asap.
