Mobility does not change – only the modes Source: H. Knoflacher Trips per person per day remain constant The Urban modes Pedestrian -, Cycle- PT-trips Motorisation Trips per Person per day Trips by car the nonurban mode Reality But why this change?

Pedestrians have highest risk in the safest city! trip types and fatality rates in central Copenhagen
Safety Requirement 1:Safe speed limits Improved safety for pedestrians, NMT, Motorised two wheelers, Public Transport commuters and cars 50 km/h arterial 30 km/h collector 20-10 km/h residential , commercial, school zones
Sustainable Safe Traffic System
a road environment with an infrastructure adapted to the limitations of the road user;
vehicles equipped with technology to simplify the driving task and provided with features that protect vulnerable and other road users;
road users that are well informed and adequately educated.
