4. Traffic Calming – Some DefinitionsTraffic Calming – Some Definitions
Definitions of traffic calming vary, but they all share the goal of reducing vehicle
speeds, improving safety, and enhancing quality of life. Most definitions focus on
engineering measures to change driver behavior. Some focus on engineering
measures that compel drivers to slow down, excluding those that use barriers to
divert traffic. The following are some example definitions.
◦ INSTITUTE OF TRANSPORTATION ENGINEERS
Traffic calming involves changes in street alignment, installation of barriers, and other
physical measures to reduce traffic speeds and/or cut-through volumes, in the interest
of street safety, livability, and other public purposes.
◦ TRANSPORTATION ASSOCIATION OF CANADA
Traffic calming involves altering of motorist behaviour on a street or on a street
network. It also includes traffic management, which involves changing traffic routes or
flows within a neighbourhood.
◦ MONTGOMERY COUNTY, MARYLAND
Traffic calming consists of operational measures such as enhanced police enforcement,
speed displays, and a community speed watch program, as well as such physical
measures as edgelines, chokers, chicanes, traffic circles, and (for the past years) speed
humps and raised crosswalks.
I believe that Traffic Calming is the topic on which Sharon Springer is leading the discussion,
so I leave further comment and presentation to her, save to make the final point that Traffic
Calming and Complete Streets are, in my opinion, two halves of a whole
solution, the one addressing arterials (Complete Streets), and the other focusing more on
tributaries (Traffic Calming), with obvious overlap in some cases.

Of all trips taken in metro areas:
50% are three miles or less
28% are one mile or less
65% of trips under one mile
are now taken by automobile
Since this 2001 NHTS report, the number has grown dramatically…
47. Isn’t it expensive?Isn’t it expensive?
“The cost is incremental or minimal in terms of the overall construction
costs for a new facility.”
Whit Clement, Virginia Secretary of Transportation
“By fully considering the needs of all non-motorized travelers (pedestrians,
bicyclists, & persons with disabilities) early in the life of a project, the costs
associated with including facilities for these travelers are minimized.”
Jeff Morales, Former Director, CalTrans
48. Is this supported in design manuals?Is this supported in design manuals?
The AASHTO “Green Book”
“Because of the demands of
vehicular traffic in congested
areas, it is often extremely
difficult to make adequate
provisions for pedestrians.
Yet this should be done,
because pedestrians are the
lifeblood of our urban
areas..."

50. Won’t this mean wider streets?
Many overly wide roads could use a “road diet”
51. What’s a road diet?
Classic road diet shrinks 4 lanes to 3 + bike lanes
52. What else does a road diet do?
Creates room for wider sidewalks
53. What else does a road diet do?
An inexpensive tool for retrofitting existing streets
54. Are street design standards enough?
This road meets minimum standards, but is sterile

State Street, Santa Barbara
1. Street vendors - help make streets into destinations. 2. Pedestrian street lamps - people need lighting at least as much as cars. 3. Curb extensions or bulb-outs - narrows the street at crosswalks. 4. Dedicated bus lanes - allows buses to be as efficient as light rail. 5. Dedicated bike lanes - allows bikes to be as efficient as well. 6. Raised, textured sidewalks - huge aesthetic difference, and clear distinction as a pedestrian-first zone. 7. Traffic lights with a leading pedestrian interval - gives pedestrians a headstart before cars start turning into their lane. 8. Bollards - Non-obtrusive pedestrian protectors. 9. Street trees and plantings - arguably the biggest aesthetic enhancer for any street. 10. Speed bump - classic traffic calming.
