Urban transport space distribution

In most cities, different transport modes compete for space. But how is space actually distributed, particularly in relation to the modal split? An investigation in the 'Green City' Freiburg indicates inverse relationships: Cars have 60% of the space and account for 30% of all trips. Bicycles have less than 3%, even though 27% of all trips are made by bike. More information can be found in "Urban space distribution and sustainable transport", Transport Reviews, http://dx.doi.org/10.1080/01441647.2016.1147101
