Tackling sustainable urban transport policy measures in transport models

According to the recent publications of the EU cities are the key places of daily mobility for the majority of people. The space of activities especially which is available for transport puts a restraint on capacity side but also raises sustainability issues. The traditional transport modelling approach does not devote enough efforts to identify the functional economic connections among city regions (what is essential in economic models) and the strategies and measures developed to stimulate a considerable shift towards sustainable life. Budapest's transport authority BKK made a vision about the city development in a form of a Sustainable Urban Mobility Plan (SUMP) called Balazs Mor Plan (BMT) and almost in parallel contracted the preparation of a centrally managed transport model as a tool to analyse and assess further measures planned in a longer term. A variable demand model was used adopting the existing models of Budapest and further developed to meet the goals. The SUMP approach led to a considerable modified model set up and inclusion of new, or modified model components like car ownership model or a newly calibrated non-home-based trip generation.
