10. Cities will be part of the country; I shall live 30 miles from my office in one direction, under a pine tree; my secretary will live 30 miles away from it too, in the other direction, under another pine tree. We shall both have our own car. We shall use up tires, wear out road surfaces and gears, consume oil and gasoline. All of which will necessitate a great deal of work … enough for all. Le Corbusier, 1935
20. Conventional Transportation Planning More Highways More Parking Prediction of More Driving Less Walking/Transit Plans for Development Conventional transportation planning assumes the following linear relationship This approach to planning is often referred to as ‘predict and provide’ There are a number of flaws in this model - including the assumption of a linear relationship
21. Conventional Transportation Planning and the Spiral of Decay More Highways More Parking More Driving Less Walking/Transit Fewer Jobs Fewer Residents = New Urbanists and others have long argued that conventional transportation planning behaves more like the model shown below Recently we started a research project which is investigating this model

24. The Fate of Hartford 1960 to 2000 More Highways More Parking More Driving Less Walking/Transit Fewer Jobs Fewer Residents = The evidence so far from our study seems to strongly support this ‘spiral of decay’ model
25. Spiral of Decay in Hartford 1960 to 2000 More Highways More Parking More Driving Less Walking/Transit Fewer Jobs Fewer Residents = Driving Up 39 % Parking Up 180 % Transit Down 45 % Walking Down 56 % Jobs Down 7 % Residents Down 25 %
26. Cambridge versus Hartford 1960 to 2000 Hartford Cambridge Driving No Change Parking Up 104 % Transit Down 20 % Walking Up 32 % Jobs Up 73 % Residents Down 7 % Driving Up 39 % Parking Up 180 % Transit Down 45 % Walking Down 56 % Jobs Down 7 % Residents Down 25 %
27. Why the Spiral of Decay? Rate of Driving Parking per Activity Cities with high driving rates require up to 5 to 6 times more parking for each new job or resident Very costly, uses lots of land and creates a horrible walking environment Hartford Cambridge
28. Why the Spiral of Decay? Cities with more parking end up accommodating many fewer jobs and residents per square mile Parking per Activity Activities per Sq. Mile Hartford Cambridge
29. City Friendly Transportation Planning What is the vision for the city? Create a transportation system that supports this vision
30. City Friendly Transportation Planning Creating a transportation system for the city we want Parking Caps No highways No street widening No street retirement Freeway removal Road Diet Eliminate one-way streets Restore on-street parking
