Dark Bollards, Dangerous Bollards


A bollard, for those who don't know the term, is one of those posts used to keep motor vehicles off of trails, sidewalks, and other non-motorized facilities. Many trail systems use them, but many use them badly, sometimes with tragic results. When a bicyclist moving at reasonable speeds runs into a bollard, common outcomes include serious injury, destruction of the bicycle frame, or even death.

If we were discussing a roadway, no competent traffic engineer would consider placing unmarked telephone poles between the lanes with no additional clearance or warnings. The results would be too obvious. Yet some of these same traffic engineers will suggest placing bollards in the middle of bicycle trails with essentially no warning for the bicyclists.

This is not usually done with the intent of maiming bicyclists, even though that is the natural outcome. Instead, the people designing these bollards simply have not thought of them as obstructions in a roadway. Worse, sometimes the bollards are positively hidden, by designs intended to blend into a park-like setting, such as bollards made of unpainted wood, or of metal painted soothing dark blues or greens.

It's easy for the lone cyclist to be dismissed as a whining malcontent, especially if the official in charge is predisposed to see cyclists that way. To avoid this, it helps to present the issue on the right terms, as a well-documented traffic safety concern.

First, let's look at two nationally-known design standards. While these do not have the force of law, they are authoritative references that are often incorporated into legal design standards.

But What Standards Apply in My Case?

AASHTO and FHWA standards are respected nationally, but your local authority may have its own design standards. You may need to ask what design standards apply to a particular project and do more research. For example, in Washington State, the WSDOT Design Manual Chapter 1020 - Bicycle Facilities addresses these issues for state-funded projects, saying

Install bollards at entrances to shared-use paths to prevent motor vehicles from entering. When locating such installations, ensure that barriers are well marked and visible to bicyclists, day or night. Do not use bollards to divert or slow path traffic. (For bollard designs, see the Standard Plans, and for pavement markings at bollards, see the MUTCD.)

This tells you that the MUTCD pavement markings apply, but you also need to find the Standard Plans to see what standards the bollards themselves must meet. In this case, WSDOT's Standard Plans call for a bollard made of 3-inch nominal steel pipe, 2'6" tall, with the top capped for safety, and four stripes of 1/2" retroreflective tape spread over 4 inches, starting 2 inches from the top of the bollard.

Presenting Your Case

Once you have this level of specific, local detail, it's much harder to dismiss you as a whining malcontent. Instead, you're a concerned citizen pointing out a design oversight that could expose the city to bad publicity or even liability.

Try to present your request calmly and rationally, even though you're dealing with a situation that could have killed you or your children. The bad design was almost certainly not installed with the intent of injuring anyone, and it doesn't do anyone any good to make the officials involved defensive. (Save their defensiveness for when someone gets hurt and decides to sue after the design isn't improved.)
