The design challenge

More research, fundamental or otherwise, is however not 
sufficient on its own. 
The ultimate task is to develop optimum combinations of 

transport and land use policies.
In advanced societies, these may incorporate the adjustment
 of existing configurations but could also include more radical 
forms of system innovation. 
In developing these solutions, the evaluation of the output of 
design processes are necessary but not enough.
It is also essential to use knowledge as an input into the processes
 for designing interventions. 
The core question is: 
What are the conceivable changes to transportation networks 
and to land use  patterns, given the objective of increasing
accessibility and the conditions imposed by other goals such 
as environmental sustainability? 
Such exploration should be regarded as a form of research 
and development into  the ‘multimodal’ fit between the features 
of new and adapted transport systems  and the land use system.
