The Silver Bullet for Bicycle Safety
What has the power to improve traffic flow, drive up property values, reduce the number of crashes, and increase the number of cyclists?
Any community serious about reducing crashes, decreasing congestion and boasting the economy should consider adding protected bike lanes. In study after study, protected bike lanes have been proven to not only increase the number of people who ride bicycles, they have also decreased the overall crash rates for everyone using the road, improved the flow of traffic and boosted the local economy with increases in property values and retail sales.
Even for a bicycle advocate, that seems a pretty bold statement, but a recent comprehensive traffic and economic study of the 30 miles of protected bike lanes installed in New York City backs up every claim. That study had the following conclusions:
- Crashes with injuries have been reduced by 17%
- Pedestrian injuries are down by 22%
- Cyclist injuries show a minor decrease even as bicycle volumes have dramatically increased
- Total injuries have dropped by 20%
- 75% decrease in average risk of a serious injury to cyclists from 2001 to 2013
- Cyclist injury risk has generally decreased on protected bicycle lane corridors within this study as cyclist volumes rise and cyclist injures decrease
- Travel speeds in the Central Business District have remained steady as protected bicycle lanes are added to the roadway network
- Travel times on Columbus Avenue have improved while vehicle volumes are maintained
- First Avenue travel speeds remained level through project area
- Travel times on 8th Avenue improved by an average of 14%
Economic Vitality & Quality of Life
- When compared to similar corridors streets that received a protected bicycle lane saw a greater increase in retail sales
- 110 trees have been added to projects within this study area, enhancing the neighborhood through which they run
- Crossing distances along corridors have been shortened anywhere between 17’ and 30’
It seems counter-intuitive, but in almost every case, when motor vehicle lanes were removed to create the room needed for protected bike lanes , the flow of traffic improved! Using GPS data from cabs from before and after the streets went on road diets to install the protected bike lanes, New York DOT was able to see that travel speeds actually increased.
But New York City isn’t the only place to get such a massive return on their investment in protected bike lanes. Pretty much every place protected bike lanes are installed, those communities get the same results. Below is a similar traffic analysis of the two-way protected bike lanes installed on 15th Street in Washington, D.C. :
There are more protected bike lanes in D.C. and all of them have similar effects increasing the number of people who ride, improving traffic safety resulting in a hugely positive return on investment. Chicago has done similar studies of their protected bike lanes with similar results, but beyond the traffic reasons to install protected lanes, there are the social and economic reasons. The prime motivation for the Mayor of Chicago to install cycletracks is to attract and retain a talented workforce. He knows Chicago is competing for talent against places like New York City, Washington, D.C., Seattle and other youth magnate metro areas.
Below are two videos I made of the protected bike lanes in Washington, D.C. and Chicago, along with a video of a protected bike lane in Seattle from the Seattle Bike Blog. If you have problems, try refreshing your screen. Click on the video image, press play and wait.
Chicago Mayor Rahm Emanuel announced the protected bike lanes in Chicago were going to lure jobs and talented workers from Seattle. Below you can read some of his bold statements from the original press conference December 17th:
“I am pleased that the City of Chicago is leading the country with the most protected bike lanes of any city in the country, and we are not resting until we get to that hundred miles. The great cities of the Pacific Northwest no longer have a free ride as the top bicycling cities in the United States. It is not an accident that, where we put our first protected bike lane is also where we have the most concentration of digital companies and digital employees. Every time you speak to entrepreneurs and people in the start-up economy and high-tech industry, one of the key things they talk about in recruiting workers is, can they have more bike lanes.”
“Two facts in the last year, coincidence? I think not: One, the City of Chicago moved from 10th to 5th of most bicycle friendly cities in the country in one year. No other city has moved up that far, that fast, that quickly… In that same year, Chicago moved up from 15th to 10th word-wide in new start-up economy. No other city has moved that far, that fast, that quickly. You cannot be for a start-up, high-tech economy and not be pro-bike, the two go hand in hand. So when my staff gave me this headline from a magazine in Portland, I couldn’t help but smile. The headline read ‘We talk in Portland, they do in Chicago.’ The Seattle Bike Blog wrote, ‘Seattle can’t wait. We are now in the position of being envious of bike lanes in Chicago.’
“I want them to be envious because I expect to not only take all their bikers, but I’ll take their jobs that come with this, all he economic growth that comes with this and the opportunities that comes with this.”
Given adding protected bike lanes makes for great headlines for elected officials, makes streets safer for everyone and boasts the local economy, we should be installing them wherever we can in our cities in Wisconsin. Madison had the nation’s first protected bike lane on University Avenue, but has not installed another one since, despite adding lots of other innovative bicycle facilities and trails. Milwaukee’s raised bike lane on Bay Street was installed in 2011, but the city has not installed a protected bike lane since.
Don’t get me wrong, as I mentioned, many cities in Wisconsin are making positive strides adding bike lanes, bike parking corrals, and even bike sharing systems, but we seem stalled on what might be the single most important improvement we can make to get more people riding. In tough economic times like these, some might argue we can’t afford niceties like protected bike lanes, but given the study results, I would argue the opposite is true. If we want to compete with other cities for jobs, boast retail sales, increase property values and reduce crashes and congestion, we simply can’t afford not to start building protected bike lanes.
