Transport and Land Uses
Let us design a new freeway…Present traffic on existing roads?Design speed? Desired LOS? Budget?But…
How many new dwellings will be built nearby?How many office bldgs? Technology parks?How many parking places are needed?What size for the new shopping center?………??
From road builders to urban planners!

Problems
Triggers:Housing densitySuburban job centersSegregation of land usesParking availability and cost
Results:Unbalanced modal splitIncreased economic, environmental and social costs

Problems
Let us use the 1990 Census Data to observe very different modal choices at different cities for the home to work trip
Is it the result of the transport system per se? Or is it due to a more complex system where many factors play a role: economic conditions, housing market, individual perceptions and choices…?

Better Processes
Transport projects opportunities:Development (macro):
Strategic and long-termExamples like Curitiba, Toronto, Stockholm…Self-containment vs dispersalUrban growth along axes through zoning and land-use incentives
Rehabilitation (micro):Tactical, short term but also effectiveIn-fill development as demand management

Better Processes
Rehabilitation (micro):It can be implemented rather quicklyLocal actions spilling over the metropolitan scaleZürich’s per capita transit trips above Curitiba’s
Any transport project – however minor –can be approached as an improvement opportunity
Let us look at several examples

Transport Approaches
City Traffic Engineering Approach:Traffic Calming a first step:
It fosters more convivial public spacesIt triggers a new relationship between pedestrians and carsIt facilitates biking
Other steps:To divert through trafficPriority for bus or LRT service

Transport Approaches
Car Parking:Critical for modal splitOn-site parking is critical to distinguish between shoppers and commuters To be seen in a wider context than just on-site provisionComplementary measures (pedestrian improvements, transit…) a must

Transport Approaches
Park-Ride facilities:Visible, well signed and secureAgain to be seen in a larger contextIt should not preclude high-density development near rail stationsPrice should be lower than downtownShuttle service of prime quality: frequent service, priority to reach downtown faster than by car (similar to an airport car rental shuttle)

Best Practices
The Netherlands ABC location policy:Locations:
A: main transit hub – few parking - downtownB: district center or small town bus junctionC: Not served by transit
Activities:A: People intensive land usesB: Commercial and service activities with low turnout (e.g..: car sales, furniture dealers…)C: Goods intensive uses

Best Practices: Beyond Transport
Among our many other recommendations, we had to include the need to attract service jobs to an area which in the past offered many industrial jobs

In a nutshell
Global Vision, Local Action… Don’t let the global vision rob you from opportunities for local changeLocal change, however limited, is important:
We need early winners to jumpstart a new processSmall changes may become showcasesDon´t forget we need a new model…
To start a process… more effectivethan relying only on end-state planning
