This post is a comment in response to an item at a Franklin blog, Fred Keller's BATTLE JOINED -- please excuse a bit of localese as well as cut-and-paste linkage, as this was done quickly:
Fred: Your "Let's widen College Avenue" argument doesn't make a lot of sense, frankly, unless you are merely looking for a cudgel with which to hammer the mayor. And, any cudgel will do, right?
You ask: Why would the mayor and city officials argue for Contest Sensitive Design when a road is being built through our community?
Really?
The idea that road congestion will increase at a steady rate is just FALSE, reinforced by a road-building industry anxious to lay more asphalt. (A mile of freeway costs three to four times the annual operating expense to the state of a rail line connecting us to Madison and Chicago -- has that not occurred to you?)
"But we need to build capacity," you might say. (Actually, what you said was: "Let's live on the edge and BUILD THE FOUR-LANER!")
But - what's that? Traffic can DECREASE? Guess what - the engineers don't account for that in their forecasts. They are all about BUILDING IT UP. If traffic rates go up +.05 in a year, they tend to keep adding the same increase every year.
Let's apply engineer-style traffic analysis: My daughter grew 1.5 inches in the past year. At this rate, she'll be over 9 feet tall by the time she's my age.

Your stance sees to be "gut instinct" against years of traffic studies NOT DONE BY ROAD BUILDERS that show widening roads actually INCREASES traffic and congestion (it's called "induced traffic"); and that creating alternative travel options (bike and ped) DECREASES traffic and congestion.
The Federal Highway Administration found in a study in Milwaukee that induced traffic accounted for 11-22 percent of the area's increased traffic from 1963 to 1991. ("Widening roads to ease traffic congestion is ineffective and expensive at the same time," said Roy Kienitz, Executive Director of the Surface Transportation Policy Project. "It's like trying to cure obesity by loosening your belt.")
I have no time to get fancy (a pillar of your argument: "waste time digging up stats for me!"), so I'm quoting here directly from another web site: A road diet on San Francisco’s Valencia Street reduced automobile through lanes from four to two, adding a center turn lane and two bike lanes. Following this change, collisions involving pedestrians declined 36%, accompanied by an increase in pedestrian traffic and a whopping 140% increase in bicycle riders – all without significantly altering automobile traffic capacity. (http://www.completestreets.org/complete-streets-fundamentals/factsheets/ease-congestion/)
Also: "When travel demand requires three moving lanes in each direction and/or double left turn and right turn lanes, the roadway impact on the adjacent community can become severe. From on urban planning standpoint, volumes of these magnitudes usually indicate too few arterial streets serving that particular corridor or a lack of freeway capacity for the longer trips that should not be on the arterial street system to begin with. Although it is recognized that geographic and urban development constraints may require these six-lane arterials in some situations, these conditions should be dealt with early in the planning process for new or developing suburbs, and some compromises and special design measures may be needed in existing corridors where other alternatives exist." (http://www.urbanstreet.info/3rd_symp_proceedings/Retrofitting%20Urban%20Arterials%20into%20Complete%20Streets.pdf)
"The phenomenon of induced traffic works in reverse as well. When New York's West Side Highway collapsed in 1973, an NYDOT study showed that 93 percent of the car trips lost did not reappear elsewhere; people simply stopped driving. A similar result accompanied the destruction of San Francisco's Embarcadero Freeway in the 1989 earthquake. Citizens voted to remove the freeway entirely despite the apocalyptic warnings of traffic engineers. Surprisingly, a recent British study found that downtown road removals tend to boost local economies, while new roads lead to higher urban unemployment. So much for road-building as a way to spur the economy." (From the book SUBURBAN NATION)
You also proceed from a FORTUNATE standpoint: You and your kids perhaps can (or will) drive. How about a bit of empathy for those of us who want to create an environment of moderate independent travel for the elderly of differently-abled? I can tell you for CERTAIN that I will not live in a community where my son cannot walk a few blocks to get on a bus or visit a friend.
Interesting statistic: Motor vehicle crashes are the leading cause of death for 15- to 20- year-olds. Franklin's 16-to-20 year-olds have NO OPTION but to drive.
Do you know that a pedestrian or bikers chance of death jumps from 45% to 85% when the speed limit jumps from a sane, residential 30 MPH to the Franklin-standard (and enforced by engineering) 40 MPH?
A 27th street public transit hub (i.e. better than the spotty bus service currently available) is a logical next step. The average American who lives in an area that's walkable and has transit spends only 9% of their income on transportation, while a person living in an area that requires driving spends more than 25%. College Ave. can feed bikes and pedestrians to a public transit hub IF ACCOMMODATIONS ARE MADE FOR THEM NOW.
Of pedestrians killed in 2007 and 2008, more than 50% died on arterial roadways, typically designed to be wide and fast (ala College Ave). Roads like these are built to move cars and too often do not have meet the needs of pedestrian or bicyclist safety.
You can dismiss safety, induced congestion, and mobility for the differently-abled and elderly. But how about ECONOMIC DEVELOPMENT?

10 years later, the sad lesson of the Segway: The suburbs killed your rocket-pack
“Instead of becoming the next Bill Gates or Henry Ford, Kamen might find himself ending up like another great American inventor, Preston Tucker, who in the 1940s built the Tucker, a car too far ahead of its time.”
I think the explanation is far simpler. The Segway revealed what we in the suburbs are getting to know more and more: You cannot walk or bike from any place of significance to any other place of significance in most modern areas of human habitation.
In a world largely created for cars, a conveyance like the Segway is nothing but a toy.
Ten years on, and I've neither ridden one nor seen one at use "in the wild" by anyone other than a mall cop or city tourist.
