Environment Benefits
• Reduced air pollution• Reduced water pollution• Reduced noise pollution• Reduced greenhouse gas
emissions• And so on…
If walking and bicycling substitute for driving!

Economic Benefits
• Reduced healthcare costs• Increased employment rates• Reduced household spending• Stimulation of local economic
development• Improved efficiency if reduced
congestion

Equity Benefits
• Transportation: For those with limited car access– Access to jobs, schools, healthcare,
shopping, etc.– Access to transit, which means
access to jobs, schools, etc.– Improved access means improved
health.

Walking vs. Biking Potential
People Potential Trip PotentialWalking No equipment needed
Almost everyone does it some
Only 2-5 mph so not many destinations within time available
Bicycling Bicycle neededMany people don’t have skills or confidence to do it
Faster at 5-15 mph so more destinations within time available

A Field Guide to the New York City Bicyclist
“As bike lanes multiply around the city, cycling grows ever more popular and subcultures of riders coalesce around a style and a sensibility. A look at the two-wheeled traffic.”

THE VINTAGE-BIKE FASHION GAL A Schwinn from the “Brady Bunch” era is the latest accessory downtown and in Brooklyn, especially for women. The bikes stand up to potholes and project a thrift-store chic. But prices are soaring.

Transit Philosophy
• Public transit provides an essential alternative to driving for…– … those who can’t
drive = “captive riders”
– … those who prefer not to drive = “choice riders”
![Page 39: Automobile Alternatives S. Handy TTP282 Transportation Orientation Seminar 11/13/09](https://reader031.vdocument.in/reader031/viewer/2022032800/56649d4d5503460f94a2baae/html5/thumbnails/39.jpg)
Transit Characteristics
• What do potential transit riders care about?– Cost– Speed– Frequency– Reliability– Comfort– Safety

Community Design Philosophy
By designing communities more like they used to be, we can reduce auto dependence
– Neighborhoods should be built around a commercial center
– Neighborhoods should be linked by a regional transit system

Congress for the New Urbanism
“Across North American and around the world, a movement called New Urbanism is changing the way our cities and towns are built…”
“New Urbanist developments create walkable neighborhoods, rather than large, single-use developments connected by streets hostile to pedestrians.”
-CNU website

“Transit-Oriented TOD’s focus of locating new construction and redevelopment in and around transit nodes is viewed by many as a promising tool for curbing sprawl and the automobile dependence it spawns.”
