Let us begin by a world tour
thanks to J.Kenworthy and F.
Laube – “The Millennium
Cities. Data base for
Sustainable Transport”
sponsored by the UITP
A follow-up to the 1989
“Cities and Automobile
Dependence” by P.Newman
and J.Kenworthy

Urban Transportation Planning – Fall 2006
Some Lessons by the Database Authors
1. Transit is the least cost option when density
is higher than 20 people per hectare
2. Growth and income does not necessarily
imply sprawl and automobile reliance
3. In fact, sharp growth in automobile traffic in
cities in developing countries may
compromise economic development
4. In sprawling affluent cities where the auto
dominates, speeds may be high but so are
the total travel times ( while no-car
households may lack accessibility)
20
Urban Transportation Planning – Fall 2006
Lessons by the Database Authors
5. Car ownership while usually has an impact
on transit ridership, may be balanced
through mobility management policies
6. Parking policies are critical to curb the auto
and provide transit priority
7. Transit supply and demand are clearly
correlated
8. Rail modes are more attractive and
competitive, and most cost efficient in
major cities
9. The ratio of transit to automobile speed is
most critical to explain modal split
21
Urban Transportation Planning – Fall 2006
Lessons by the Database Authors
10. Low transit fares, while necessary in social
terms, are not critical to capture motorists
11. Sustainable policy = urban planning +
traffic and parking controls + public
transport with traffic priority
12. In developing countries, transit supply
shortage and high operator profits
See “Millennium Cities Database for Sustainable
Mobility. Analyses and Recommendations”

Urban Transportation Planning – Fall 2006
Our suggestions and lessons
Main issue is quality of life
„ Not auto vs. transit, rather auto versus
transit + non-motorized trips
„ The virtuous cycle: low fares higher
ridership higher frequencies
„ Accessibility varies greatly within a
metropolitan area (walk trips in Beacon
Hill and auto trips in Framingham)
„
23
Urban Transportation Planning – Fall 2006
Our suggestions and lessons
„
„
„
„
Cost based on local GDP obscures the fact
that some costs are local (ie driver wages)
with multiplier effects, while others are
international (ie. fuel, automobiles…)
If you substract the transportations costs
from the average GDP in a city, you may find
that many such cities have a higher GDP than
equivalent US cities
Metropolitan area as an archipelago of
transport arrangements
Let us continue the discussion on how to deal
with the “ocean of red circles”
24
Urban Transportation Planning – Fall 2006
A few tips…
„
„
„
„
„
„
„
Frustration while interpreting someone else
data (or sometimes even yours)
Work in pairs with complementary skills
We are dealing with a complex problem (with
social, economic and technical issues), simple
hypotheses will not suffice (no magic bullets)
Simple linear regression or multi-regression?
“We love our cars in the US” (and in Rome,
Nairobi, New Delhi, Copenhagen ..)
The myth about income and transit use
Do work with this database in the future
