1 Completing the paradigm shift in street planning and design: who s your client? Dr. Jeannette Montufar, P.Eng., PTOE Complete Streets Forum Toronto, October

2 June 29, 1956

3 Goals of Federal Aid Highway Act National defense High-speed driving Eliminate traffic congestion Make coast to coast transport more efficient Replace undesirable slum areas with pristine ribbons of concrete

4 Toronto interchange, Construction of Boston s Central Artery,

5 I30/I45 interchange in Dallas, I35 through Duluth, MN, 1980s

6 Interstate 5 through Seattle Highway 401 Interstate 75 through Atlanta

7 Unanticipated (?) side effects People displaced from their homes Freeways sliced communities in half Abandonment and decay of city after city Traffic congestion Quality of life? Economic development Los Angeles freeway

8 Daily long-haul truck traffic,

9 December 18, 1991 Paradigm shift

10 Goals of ISTEA Address changing needs of America Reduce traffic congestion Promote safety Protect the environment Improve quality of life

11 Sustainability Increasing level of sustainability Walking Cycling Public transit Carpooling Cars

12 Complete streets Roads designed to be safe for drivers, bicyclists, transit vehicles and users, and pedestrians of all ages and abilities It is about changing the decision-making and design process It is about policy and institutional change

13 Challenge Transport is derived demand LOS V/C Delay Safety Streets don t change

17 Considerations for complete streets One size does not fit all design should reflect users, context of the area and land use Identify modal priorities walking, cycling, taking transit, movement of goods, cars What are the characteristics of those users?

18 Ped walking speed in Canada 100% Cumulative Percent (%) 80% 60% 40% 20% 0% Walking Speed (m/s) All - Younger All - Older Source: Montufar et al (2013), Pedestrian walking speed for traffic operations in Canada TAC report.

21 Considerations for complete streets One size does not fit all design should reflect users, context of the area and land use Identify modal priorities walking, cycling, taking transit, movement of goods, cars What are the characteristics of those users? Be prepared for trade-offs Whatever you build will need maintenance Economic vitality and equity driving forces Performance evaluation is essential
