Development of modal split in the Czech Republic according to national census

Abstract

One of the key parameters during the analysis of traffic in the cities is the modal split, which shows how is the role of different modes of transport in the city. Every 10 years in the Czech Republic, the Czech Statistical Office makes a census of houses, people and flats and a regular commute to work and school (or modal split). However, this data is not using for the further needs of city traffic planning, while small towns (15-60,000 inhabitants) have not another source of data for planning of traffic behaviour. This paper follows the final report from the CYCLE21 project, which analysed data from 2001. This paper examines the development of data between 2001 and 2011 (when the last census took place in the Czech Republic) and analyses the trend of change of traffic behaviour. Concurrently, this paper introduces methodological documents created by the authors of the paper for the future census in 2021 so that it is possible to make prediction of modal split in individual cities in the Czech Republic.
