Premised on the need to reduce resource

consumption in transport, particularly the
dependence on oil
Market mechanisms (e.g. prices) can lead to
Strategic planning and investment is required to

Travel decisions as a choice, framed within
Travel decisions seen as more complex
rational decision making
assemblages of routines, habits and constraints
Traffic and mobility focus, particularly on
Travel as important to social activity,
increasing vehicle volume and throughput
improvements to accessibility, improvement to the
quality of the journey experience, multi-modal
'Predict and provide' approach to analysis
Traffic demand management, improving the
journey experience, slowing movement down
where appropriate
Concern over the main transport mode, rather
Concern over the door to door travel - improving
than the total journey
the entire journey experience
Street as a road
Street as a space with multiple users
Motorised transport
All modes of transport, often in a hierarchy with
pedestrian and cyclist at the top and car users at
the bottom
Focus on major schemes, mainly road
Integrated strategies and packages of
complementary measures
Accept trends and examine transport issues
Concern about achieving the desirable city over
over the shorter term
the longer term and the role that transport should
play
Transport planning disregarding context
Strategic and local urban planning as a central
element in achieving sustainable transport
Demand forecasting, mainly traffic-based with
Visioning and scenario analysis, benchmarking for
some public transport
cities and transport
Social and environmental objectives given less

Economic evaluation, quantitative analysis given

Travel as a derived demand, instrumental factors
Travel as a valued activity as well as a derived

Concepts of slower travel, reasonable travel time,
minimised

Segregation of pedestrians and traffic
Integration of pedestrians, cyclists and traffic
