Urban roads are characterised by the multiple functions they fulfil: 
they carry vehicular traffic, provide car parking, accommodate 
pedestrian traffic, and enable us to access shops, amenities 
and housing. And yet the car has progressively taken over more 
and more of the available road space, at the expense of other 
road users. Today, in response to social and environmental demands, 
public policy seeks to give priority to other forms of travel, 
such as cycling, walking and public transport, by controlling car 
use more effectively.
How should streets be organised in order to accommodate all 
these uses? How can different transport modes and the various 
needs of residents and other users be reconciled? 
How should the available space be shared out? Of course, there 
is no single answer to these questions: each individual street must 
be considered on its merits and according to the 
importance of its different functions.With this in mind, this work 
provides road designers with techniques and tools to help them 
successfully ration urban road space while maintaining 
a "unifying" approach. In this guide, the reader will find all the 
recommendations necessary to create variable cross-sections 
and their constituent elements: footpaths, carriageways, 
dedicated spaces for cyclists and public transport, separators, 
and vegetation.
