The paper attempts to identify factors that influence modal split for journeys to work in cities with populations of between 100 thousand and 500 thousand in Germany, the Netherlands, Switzerland and the UK. The sample consisted of 34 cities. The analysis revealed a significant negative correlation between modal shares of motorised modes and public transport. A negative correlation between motorised modes and non-motorised modes, albeit to a lesser degree, was also found. Public transport- and non-motorised mode share, however, were not correlated.
