Safety Paths: Not Safe for Cycling

Sunday, July 13th, 2008

First, let’s clarify what safety paths are. The term safety path is apparently a local definition usually nearly exclusively within Oakland County, Michigan. AASHTO’s Guidelines for the Development of Bicycling Facilities contains the generally accepted standard terms and definitions for bicycle facilities. According to AASHTO’s definitions, safety paths are wide sidewalks.

Also from the AASHTO guidelines:

Utilizing or providing a sidewalk as a shared use path is unsatisfactory for a variety of reasons. Sidewalks are typically designed for pedestrian speed and maneuverability and are not safe for higher speed bicycle use. Conflicts are common between pedestrians traveling at low speeds and bicyclists… At intersections, motorists are often not looking for bicyclists.

It is important to recognize that the development of extremely wide sidewalks does not necessary add to the safety of sidewalk bicycle travel. Wide sidewalks might encourage higher speed bicycle use and increase potential for conflicts with motor vehicles at intersections, as well as with pedestrians and fixed objects.

There are two major studies that compared bicycle safety on roads and sidewalks.

Bicycling safety in Oakland County: It’s not about the money

Friday, June 27th, 2008

In a prior post, we noted that many road agencies and municipalities in Metro Detroit are the major roadblock to getting safe bicycling facilities.

For example, the Road Commission of Oakland County refuses to acknowledge much less use best practices for bicycling facilities. They ignore the American Association of State Highway Officials (AASHTO) guidelines for bicycling facilities. They ignore Federal Highway Administration guidance. They ignore bicycling safety studies that show their policies have been consistently found to be unsafe.

We appreciate the fact that Craig Bryson, Public Information Officer for the Road Commission for Oakland County responded:

The Road Commission for Oakland County has no objection to bikers. We simply have no money available to make costly improvements to roads to allow bikers. We cannot afford to simply maintain smooth pavement on the roads or even begin to address the massive congestion that clogs our roads everyday. It would be very difficult to justify spending scarce resources on bike facilities when we can’t maintain the existing roads. If you are proposing additional funding just for bike facilities, we’re more than willing to listen.

However, Craig isn’t correct. It’s not about the road money.

What Bike Helmet Advocates Don’t Tell You

Monday, June 9th, 2008

If we’re going to make bicycling safer in the U.S., we need to be honest about what needs to be done.

The primary safety solution from many groups is to wear a helmet. But, according to research, wearing helmets is not the best way to improve bicycling safety. Creating safe bicycle facilities, increasing bicycle use, and educating users are the best means for improving safety. The results from the Netherlands support this. It’s one of the safest places to bike in the world yet almost no one wears helmets.

What do you call a cyclist wearing a helmet in the Netherlands? A tourist.

Helmet use Fatalities per 100 million trips
U.S. 38% 21
Germany 2% 8.2
Netherlands 0.1% 1.6

One study summarizes the six priorities that Germany and the Netherlands use to make biking so safe:

  • Better Facilities for Walking and Cycling
  • Traffic Calming of Residential Neighborhoods
  • Urban Design Oriented to People and Not Cars
  • Restrictions on Motor Vehicle Use
  • Traffic Education
  • Traffic Regulations and Enforcement

The big challenge in Metro Detroit is many road agencies and municipalities don’t know what better bicycling facilities are. For example, the Road Commission of Oakland County refuses to acknowledge much less use best practices for bicycling facilities. They ignore the American Association of State Highway Officials (AASHTO) guidelines for bicycling facilities. They ignore Federal Highway Administration guidance. They ignore bicycling safety studies that show their policies have been consistently found to be unsafe.

And similarly, many cities have followed the Road Commission’s lead. Rochester Hills and West Bloomfield have pursued wide sidewalks (ironically called “safety” paths) despite the overwhelming evidence that these are not safe options for cyclists.

If we truly want safe cycling, we need to start by forcing our local road agencies and municipalities to use best practices and provide safe non-motorized transportation options for cyclists. This should be our primary campaign. And that message needs to come from cyclists, citizens, AAA, medical professionals, health experts, the Traffic Improvement Association (TIA), and others.

This doesn’t mean helmet use should be discouraged. Helmets can lessen injuries when cyclists are hit. But it’s much better to prevent those “hits” in the first place.
