Communities, not Cul de sacs

Update: Trees make streets safer and Fixing a perfect storm of bad planning and design.

Eric M. Weiss writes in the Washington Post on 22 March 2009 about In Va., Vision of Suburbia at a Crossroads: Targeting Cul-de-Sacs, Rules Now Require Through Streets in New Subdivisions

The state has decided that all new subdivisions must have through streets linking them with neighboring subdivisions, schools and shopping areas. State officials say the new regulations will improve safety and accessibility and save money: No more single entrances and exits onto clogged secondary roads. Quicker responses by emergency vehicles. Lower road maintenance costs for governments.
Banning cul-de-sacs was one of the New York Times Magazine’s 9th Annual Year in Ideas, because it’s safer and less expensive:
The changes come as cash-strapped states and localities can no longer afford the inexorable widening of secondary roads that are overburdened with traffic from the subdivisions, strip malls, schools and office buildings that feed into them. The system forces drivers to enter these traffic-choked roads to go even 50 yards or so to the neighborhood coffeehouse or elementary school. North Carolina and Portland, Ore., are moving on similar fronts.
Or, as UGA Prof Dorfman said:
“sprawling residential growth is a certain ticket to fiscal ruin”
What to do?
So now, Virginia will maintain only new subdivision streets that meet its connectivity, road and sidewalk requirements. That’s a big stick, because unlike in Maryland and most other states, the Transportation Department maintains and plows almost all of Virginia’s roads, including streets with as few as three homes.
The state doesn’t do all that many local roads in Georgia, but counties tend to slavishly follow state road standards.
The new requirements also call for roads that are dramatically narrower, 24 feet to 29 feet wide for local streets. Now subdivision streets can be 40 feet wide — wider than three highway lanes — and cars often share the asphalt with baby carriages and joggers. Montgomery County also recently approved new rules for narrower streets. Narrower roads reduce speeds, decrease storm water runoff and save on maintenance costs, officials say.
You mean wider is not safer? Maybe even slower is safer?

Cul-de-sacs are unsafe and scary:

In the Washington suburbs few subjects are as contentious as through traffic. The current system, which has created developments designed to limit cut-through traffic, has made homeowners more afraid of outsiders coming through their development, because the few roads that do connect are often, in Duany’s words, “traffic sewers” filled with speeding commuters.

“The cul-de-sac compensates for roads that are so over-designed that people speed on them,” Duany said. “So instead of dealing with the heart of the problem, they created a Band-Aid, a cul-de-sac.”

So why not deal with the heart of the problem? Build roads that connect to stores and work, and design subdivisions that facilitate transportation other than cars.

This can be done at the county level:

“We’re trying to create flexibility so we have roads that are more pedestrian- and bicycle-oriented instead of a one size fits all,” said Montgomery County Council member Michael Knapp (D-Upcounty).

Knapp said the county’s next master plan will also stress connectivity, similar to the Virginia plan, especially as the county fills in its existing open development areas and connecting the new to the old becomes more imperative.

“As you try to create a sense of place, a development of 100 houses ending in a cul-de-sac next to another development ending in a cul-de-sac isn’t going to work,” he said.

A sense of place that’s connected and has room for pedestrians and bicycles. Almost like a village green.

  1. Repeal_The_Va_Radar_Detector_Ban

    As you may know, Virginia is the only state that bans the use and sale of radar detectors. There is no evidence that the radar detector ban increases highway safety. Our nation’s fatality rates have fallen consistently for almost two decades. Virginia’s fatality rate has also fallen, but not any more dramatically than it has nationwide. Research has even shown that radar detector owners have a lower accident rate than motorists who do not own a detector.
    Maintaining the ban is not in the best interest of Virginians or visitors to the state. I know and know of people that will not drive in Virginia due to this ban. Unjust enforcement practices are not unheard of, and radar detectors can keep safe motorists from being exploited by abusive speed traps. Likewise, the ban has a negative impact on Virginia’s business community. Electronic distributors lose business to neighboring states and Virginia misses out on valuable sales tax revenue.
    Radar detector bans do not work. Research and experience show that radar detector bans do not result in lower accident rates, improved speed-limit compliance or reduce auto insurance expenditures.
    • The Virginia radar detector ban is difficult and expensive to enforce. The Virginia ban diverts precious law enforcement resources from more important duties and this ban may be ILLEGAL.
    • Radar detectors are legal in the rest of the nation, in all 49 other states. In fact, the first state to test a radar detector ban, Connecticut, repealed the law – it ruled the law was ineffective and unfair. It is time for our Virginia to join the rest of the nation.
    • It has never been shown that radar detectors cause accidents or even encourage motorists to drive faster than they would otherwise. The Yankelovich – Clancy – Shulman Radar Detector Study conducted in 1987, showed that radar detector users drove an average of 34% further between accidents (233,933 miles versus 174,554 miles) than non radar detector users. The study also showed that they have much higher seat belt use compliance. If drivers with radar detectors have fewer accidents, it follows that they have reduced insurance costs – it is counterproductive to ban radar detectors.
    • In a similar study performed in Great Britain by MORI in 2001 the summary reports that “Users (of radar detectors) appear to travel 50% further between accidents than non-users. In this survey the users interviewed traveling on average 217,353 miles between accidents compared to 143,401 miles between accidents of those non-users randomly drawn from the general public.” The MORI study also reported “Three quarters agree, perhaps unsurprisingly, that since purchasing a radar detector they have become more conscious about keeping to the speed limit…” and “Three in five detector users claim to have become a safer driver since purchasing a detector.”
    • Modern radar detectors play a significant role in preventing accidents and laying the technology foundation for the Safety Warning System® (SWS). Radar detectors with SWS alert motorists to oncoming emergency vehicles, potential road hazards, and unusual traffic conditions. There are more than 10 million radar detectors with SWS in use nationwide. The federal government has earmarked $2.1 million for further study of the SWS over a three-year period of time. The U.S. Department of Transportation is administering grants to state and local governments to purchase the SWS system and study its effectiveness (for example, in the form of SWS transmitters for school buses and emergency vehicles). The drivers of Virginia deserve the right to the important safety benefits that SWS delivers.
