Vintage Cruiser, by Ryan Wiese–on display at
the Bike Art Exhibit (Dairy Center) through March

The most professionally produced promotional bike video just came out from Kona Productions. It obsesses over Portland (really, again?). The cutest quote is from the kid at 2:38, “bicycling helps my community because it helps the air around…[affrmative nod] and it helps the polar bears [while dancing with his shoulders]…polar bears are epic!”

Mineta report on promoting bicycle safety

03.21.12

0

The research reports keep coming in. Here is another one with lots of secondary data and sources, prepared in a manner that crosses between advocacy and research, and is pretty accessible. The focus in the title suggests safety but it is a bit broader in its coverage. Warning: it is a big long.

Just released: The Mineta Transportation Institute recently published a report that leverages literature review and case studies in the San Francisco Bay area and Portland OR to recommend ways to improve safety for bicycle commuters. Promoting Bicycle Commuter Safety includes chapters on risks, application of social psychology to bike safety, dimensions of effective practices, and more. The report also includes illustrative tables and photos. Principal investigator was Asbjorn Osland, PhD, with several chapter contributors. The 157-page report is available for free PDF download from transweb.sjsu.edu/project/2927.html

Robustly testing the effect of bicycle network quality

03.20.12

Most are familiar with the “go to” studies pointing to correlations between the quantity of bicycle facilities and use[1]. These are certainly a good starting point; but there are always more layers to the onion.

In particular,

-what do we know about the overall “quality” of the facilities?

-what is the role of network characteristics?

-what are different ways to operationalize characteristics of the network?

-how do these aspects relate to different ways of measuring key dependent variables?

Jessica Schoner from the University of Minnesota just received an honorable mention from APA’s Transportation Planning Division for her paper Shifting Gears: A cross-regional analysis of bicycle facility networks and ridership. This is a remarkably impressive piece of work for a class term paper at the master’s level—not even a thesis or dissertation! Said one reviewer: “Of all the years doing this contest this is by far the best on bicycling I’ve seen.”

The following attributes and reflections are of particular interest:

-She digs deep into elements of general network qualities and examines size, connectivity, directness, and fragmentation,

-She hones in on using percent of bicycle commuters that are women as one of the dependent variables. This is interesting not only because it helps shed light on the gender balance of bicycle commuters but also because women are often considered an indicator species for building bike-friendly cities[2].

-The findings suggest that connectivity, and to some extent fragmentation, are important factors associated with both bicycle ridership and the percentage of female bicycle commuters, even when controlling for household size and structure, vehicle ownership, and city size.

-While we all cry that there is not reliable data when it comes to cycling, there is a lot you can do with secondary data. She did a lot of work to uncover such for 74 communities.

It is comforting to see yet another example of really robust cycling research.

Won’t Somebody Please Stop This Guy Stealing Bikes in New York City?

03.19.12

This video depicting Casie Neistat (of HBO fame) stealing his own bike is interesting from a human nature standpoint. Sure, it is a bit unsettling to see that no one in New York cares about bike theft, even when it is under their own nose. Sure, it is funny to see that the only comment he receives is from Hector providing tips on how to steal a bike more quickly.

But what is going on here?

Is it that bikes, as material possessions, are too plentiful for anyone to care?

Is that New Yorkers are so brash and too busy to care about such miniscule petty crimes, generally?

Is it that New Yorkers don’t care about cycling?

Is it that social capital in New York really that low?

What is the transferability of this story? Surely it would not have the same outcome in North Dakota.

Choking the choke points

03.19.12

0

For much of the population, a bicycle route is only as good as its weakest link. An average commuter can bliss out for 90 percent of their ride along an off-street path; but if the remaining 10 percent involve a particularly unsafe intersection or a troubling bridge crossing, it could be a show stopper. I call these choke points; they are often thought of as the weakest link in the chain of bicycle facilities for a city.

They represent an often glossed over, but important tenet of bicycle planning; ironically, they are also one of the most difficult to stay on top of. They come in two varieties. We can refer to them as (1) facility disruptions and (2) naturals.

Facility disruption: It’s simple for a city with no facilities to have no chokepoints; the whole city is a choke point. There are no real facilities that end prematurely. The more facilities a city brings on-line, the more likely choke points result. Every new lane or path needs a starting and ending point[1] and unless they are seamlessly woven into the existing fabric, there is likely some discontinuity that will result.

Naturals: Some cities are naturals for choke points. Seattle, comprised of labyrinth of water barriers which serve to funnel cyclists to select routes, is littered with them. In most communities the ordinary constriction of roadway space owing to bridges over railroads or rivers provides good fodder for where chokepoints fester. And, oftentimes the worst choke points are temporary, resulting from detours owing to construction[2], which is probably best labeled a natural occurance.

The best thing a city can do about choke points is threefold: identify, address, and minimize them.

One of the more systematic efforts to address these comes from Minneapolis, Minnesota. As of 2010, they had 54 gaps in their system[3]–one for each square mile of the entire city[4]. What other cities are taking formal and detailed inventory of the discontinuities and reporting on them?

[1] Starting and ending point: Krizek, K. J. and R. W. Roland (2005). “What is at the end of the road? Understanding discontinuities of on-street bicycle lanes in urban settings.” Transportation Research Part D: Transport and Environment 10(1): 55-68.

[2] Choke points owing to construction: Krizek, K. J. (2002). Even Here, A Failure to Respect Cyclists’ Needs. Minneapolis Star Tribune,. Minneapolis: A2 (commentary).

[3] Gaps in the Minneapolis system: see chapter 7 in Pflaum, D. (2011). Minneapolis Bicycle Master Plan. Minneapolis, Minneapolis Public Works.

[4] One gap per square mile in Minneapolis: The city’s area is 58.4 square miles; once you account for the fact that 6 percent of that area is water, it comes to 54 square miles.

Standing room only for bike art

Maybe it was the warm temps. Maybe it had to do the full moon the night prior. It is likely just Boulder’s preoccupation with wanting to obsess about all things bikes.

It was jam packed Friday for the opening night of the bike art exhibit at the Dairy Center for the Arts in Boulder. Artists from over 22 states are represented and it is really an impressive display–perhaps the largest collection in a single location I have every seen. Now happening only until the end of the month.

Cycling – transit integration

03.09.12

The whole enterprise of integrating cycling with transit is a remarkably understudied issue, lacking a solid knowledge base. Yet, it might have high potential.

Recently published: Krizek, Kevin J. and Eric Stonebraker (2011). Assessing Options to Enhance Cycling-Transit Integration, Transportation Research Record, Journal of the Transportation Research Board. No. 2217: pp. 162–167. DOI: 10.3141.

Abstract: Cycling continues to increase in popularity and garner attention for the ability to achieve environmental, health, and congestion-mitigation benefits for communities. Although the growth in both cycling and transit may be in small part attributed to bicycle and transit integration, the growth is difficult to measure. Which of the variety of available strategies for bicycle and transit integration—such as increased bicycle parking at stops, increased bicycle capacity on transit vehicles, and shared bicycle

infrastructure—is more cost-effective? Which strategies will yield the highest number of cycle transit users? To fill a void in the literature about integrating bicycling and transit, four common bicycle and transit integration strategies were described and assessed. A framework was developed for evaluating strategies, and a preliminary cost-effectiveness assessment was conducted. Cost-effectiveness comprises costs and cyclists’ preferences for each strategy. Preferences were gathered through stated preference surveys from focus groups in five case study communities and calculated according to the analytic hierarchy process, a multicriterion decision-making tool. Transit with a bicycle aboard was most preferred by cyclists, whereas results of the cost-effectiveness measure suggest that enhancing bicycle parking at a transit stop proved most cost-effective when compared with the most common bicycle onboard transit configuration: front-mounted bicycle racks on buses. The limited growth potential for bicycles aboard transit requires consideration of alternatives. The overall importance that cyclists assigned to security suggested considerable room for creative solutions to improve the favorability of the other strategies while addressing some inherent capacity limitations of the most popular strategy: transporting the bicycle with the rider on transit.

While I am trying to encourage my 6 year old to abandon using the word “hate,” the figures from this sidewalk are are still interesting.
