Urban Transportation Planning – Fall 2006 Assignment no 4 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 1 Urban Transportation Planning – Fall 2006 … And it is complemented by its follow-up A set of 50 cities with evolution of performance between 1995 and 2001, plus mobility policies in 2006 2 Urban Transportation Planning – Fall 2006 Urban Density is critical… 200 URBAN DENSITY 160 Persons/Ha 120 80 40 0 Western Eastern North Latin Middle Europe Europe America America East Africa Asian Other Affluent Asian (55.1) (101.67) (134.36) (71.36) (18.67) (89.66) (76.79) (189.75) Ocean A (15.02) World Regions Figure by MIT OCW, adapted from the UITP Millennium Cities Database. . 3 Urban Transportation Planning – Fall 2006 The higher the density, the higher… Modal Choice (% Public TransportCycling-Walking) Density (Inhabitants/Hectare) vs Modal Choice (% Public Transport + Cycling + Walking) 100 All Cities 80 60 40 U.S.A.

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” by Jean Vivier, UITP 22 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 25 Urban Transportation Planning – Fall 2006 Good luck and enjoy… 26
