12Creating Paradise
- Paradise is not a distant destination, it is
something we create in our own communities.
13Sustainable Planning
- Sustainability emphasizes the integrated
nature of human activities and therefore the need
to coordinate planning among different sectors,
jurisdictions and groups.

14Preventing Problems
- Sustainability planning is to development
what preventive medicine is to health it
anticipates and manages problems rather than
waiting for crises to develop.
15Sustainability
16Paradigm Shifts
- Growth - expanding, doing more.
- ?
- Development - improving, doing better.
- Mobility - physical movement.
- ?
- Accessibility - obtaining desired goods, services
and activities.
17Resource Sustainability
- Would we have a sustainable transportation
system if all automobiles were solar powered?

23Trends Supporting Multi-Modalism
- Motor vehicle saturation.
- Aging population.
- Rising fuel prices.
- Increased urbanization.
- Increased traffic and parking congestion.
- Rising roadway construction costs and declining
economic return from increased roadway capacity. - Environmental concerns.
- Health Concerns

26Aging Population

2050
27Urbanization
- Between the 1940s and 1980s the population
became more suburbanized. Now, about half of
North Americans live in suburbs.
28Value of Highway Expansion
- When the highway system was being developed in
the 1950s and 60s it provided high returns on
investment. Now that the system is mature,
economic returns have declined.
29Transit Auto Growth Trends

30Optimal Modal Split
Small shifts from automobile to alternative modes
can result in a large increase in walking,
cycling and public transit demand. For example,
a 5 reduction in driving can increase use of
alternative modes by 50.

31Transportation Public Health Impacts
- Traffic safety
- Pollution
- Physical fitness
- Metal health - stress
- Basic mobility (including access to medical
services) - Affordability
- Community cohesion

32Transportation Health Impacts
33Traffic Crash Costs
Comprehensive Evaluation indicates that traffic
crashes impose costs totalling more than a third
of a trillion dollars.
34Traffic Fatality Rates
- When crash rates are measured per vehicle
mile, they declined significantly, but when
measured per capita they show relatively little
decline due to increased per capita vehicle
mileage.

40Non-motorized Safety Impacts
41Nonmotorized Travel
Per capita traffic fatality rates tend to
decline as nonmotorized travel increases.
42Smart Growth Safety Impacts
43Health Concerns
- Obesity Rates (BMI gt 30)
- There is increasing concern about the health
problems that result from reduced physical
activity, and the value of transport systems that
accommodate walking and cycling.
44What Gets People Moving?
- Walking is a natural and essential activity.
If you ask sedentary people what physical
activity they will most likely to stick with,
walking usually ranks first.
45Encouraging Physical Activity
- Dogs stimulate recreational walking and
running.
46Obesity Rates Versus Mode Split
47Physical Activity Rates
- Sufficient 30 min., 5 days/week
- Sporadic Some weekly activity.
- Inactive Sedentary

48Active Transportation Valuation
Transport New Zealands Economic Evaluation
Manual (EEM) provides monetary values for the
health benefits of active transportation (Volume
2, section 3.8, p 3-22). It assumes that half of
the benefit is internal to the people who
increase their activity level by walking or
cycling, and half are external benefits to
society such as hospital cost savings.

53Emissions Reduction Strategies
- Vehicle fuel economy and emission rates.
- Fuel carbon content
- Total amount of driving (VMT)
54Effectiveness and Scope of Benefits
55Comparing Benefits
55
56Equity
- A more diverse transportation systems helps
achieve equity objectives - A fair share of public resources for non-drivers.
- Financial savings to lower-income people.
- Increased opportunity to people who are
physically, socially or economically
disadvantaged.
57Basic Mobility
- Certain goods and services are considered
essential or basic - Emergency services (police, fire, ambulances,
etc.). - Public services and utilities (garbage
collection, utility maintenance, etc.). - Health care.
- Basic food and clothing.
- Education and employment (commuting).
- Some social and recreational activities.
- Mail and freight delivery.
57
58Economic Development Benefits
- Reducing vehicle expenditures and expanding
transit service increases regional employment and
business activity. - Reducing transportation costs (congestion,
parking, property taxes) to businesses increases
productivity and competitiveness. - Agglomeration efficiencies.
- Stimulates development and increases local
property values. - Increases affordability, allowing businesses to
attract employees in areas with high living
costs.

62Community Livability Cohesion
- Community Livability refers to the
environmental and social quality of an area as
perceived by residents, employees, customers and
visitors. - Community Cohesion refers to the quantity and
quality of positive interactions among people in
a community. - Streets that are attractive, safe and
suitable for walking and cycling increase
community livability and cohesion.
63The Value of Community
- Human happiness requires a balance of material
wealth and non-material goods such as friendship,
security and purpose. As people become wealthier,
the relative value of nonmaterial goods tends to
increase.
What we really seem to want, according to the
economists and psychologists conducting such
research, is more community. Standard economic
theory has long assured us that were insatiable
bundles of desires. That may be true, but more
and more it feels like our greatest wish is for
more contact with other people. (National
Geographic, 2006)
64Indicators
- People being courteous and helpful to strangers.
- Friendly conversations among strangers.
- People of diverse incomes and abilities
interacting in positive ways. - People reading and resting.
- Children, seniors and people with disabilities
traveling independently.
65Life Satisfaction
66Example - Smoking
- Medical experts once promoted safer cigarettes
and cancer cures. Increasingly they now emphasize
programs to stop smoking and regulations to
reduce exposure to second-hand smoke.
67Example Traffic Safety
- Traffic safety experts once favored passive
safety technologies (safer roadways, crash
resistant vehicles, air bags) because they do not
require behavior change. - But these by themselves these tend to have
modest safety benefits.
68Example Traffic Safety
- Active safety strategies, such as more
cautious driving, seat belts, child restraints
and helmets, provide the greatest potential
safety benefits. - Seat belt use reduces traffic fatalities by
45. Air bags can reduce fatalities an additional
10, but require seat belt use to be effective.
69Example Traffic Safety
- Technology/Passive
- Crash-friendly roadways
- Crash-friendly vehicles
- Air bags
- Improved emergency response
- Behavior Change
- Seat belts use
- Child restraints
- Helmets
- Reduced drunk driving
- Speed reduction
- Choose safer vehicles
- Driver skill development
70Example Traffic Safety
- The greatest traffic safety gains have
resulted from changes in travel behavior, not
from new technologies. Given suitable products
(e.g., convenient and comfortable seat belts) and
encouragement, many motorists want to choose
safer habits.
71Reform Planning Practices
- Multi-modal planning create a diverse and
integrated transportation system. - Fix-It-First Major capacity expansion deferred
until basic maintenance and operations needs are
met. - Least-cost planning equal funding for mobility
management solutions. - Context Sensitive Design Designing roadways to
reflect local needs and preferences.
72Change Management
- Be a change agent
- Think outside the box
- Turn problems into opportunities.
- Create the future you want to live in
- Build partnerships
- Think strategically
- We CAN do that!
73Supported by Professional Organizations
- Institute of Transportation Engineers.
- American Planning Association.
- American Farmland Trust.
- Federal, state, regional and local planning and
transportation agencies. - International City/County Management Association
- National Governors Association
- Health organizations.
- And much more...
74Motorists Benefit Too
- More balanced transport policy is no more
anti-car than a healthy diet is anti-food.
Motorists have every reason to support these
reforms - Reduced traffic and parking congestion.
- Improved safety.
- Improved travel options.
- Reduced chauffeuring burden.
- Often the quickest and most cost effective way to
improve driving conditions.
