Ed. note: In the spring of 2011, I suggested friends and readers of my blog Steven Can Plan write letters to the Chicago Department of Transportation about the distinct lack of bicycle infrastructure in the plan to redesign the intersection and streets at Damen Avenue, Fullerton Avenue, and Elston Avenue. It’s more than an intersection overhaul.  I then reported that it appears the letters you and I sent were positively received and bicycle infrastructure was added to the plan. The project, now set forth, will have three separated intersections (which should reduce the complexity of traffic signal cycles and automobile turning movements) all connected by roads with four travel lanes. Elston and Damen Avenues will have protected and conventional bike lanes, respectively. A Grid Chicago reader emailed us three weeks ago to ask us to reconsider our support for that design.

Tony Horvath lives in Lakeview and is a business analyst for Merrill Corporation. He doesn’t own a car but remembers the intersection from when he used to own a car and drove through it often. He commutes by ‘L’ but has also biked through the intersection and in the area. -Steven Continue reading Should I reconsider my support for the Damen-Elston-Fullerton intersection plan?

Desplaines boss, Desplaines! A new protected bike lane takes shape

Cars are currently being parked in the Desplaines bike lane, but probably not for long. Photo taken just south of Madison Street. 

This is an exciting moment for cycling in Chicago as the department of transportation races to meet its goal of reaching a total of thirty miles of protected and buffered bike lanes before it gets too cold to lay thermoplastic. As Steven wrote yesterday, CDOT began installing new traffic signals last weekend for the eagerly awaited, two-way protected lane slated for a 1.2-mile stretch of Dearborn Street between Polk and Kinzie streets.

Since Mayor Emanuel himself declared the lane would be built this fall, if the weather holds up it’s likely this “game-changing” facility will soon be completed. As the first protected lane in the central Loop and the first two-way protected lane, Dearborn will probably draw some criticism from the anti-bike crowd. But the 4,500 signatures the Active Transportation Alliance recently collected in support of the lane prove that plenty of Chicagoans are looking forward to getting a first-class downtown bike commuting route.

Grid Chicago readers alerted us that CDOT also began striping new protected bike lanes on Desplaines Street in the West Loop last weekend, so yesterday afternoon I pedaled downtown for a look-see. From Kinzie to Fulton Street, a two-way section, the department is putting in “enhanced” shared lane markings, the same type that were recently installed on Wells Street south of the river. These markings encourage cyclists to ride in the middle of the lane; presumably “Bikes may use full lane” signs will be installed, as they were on Wells.

Danish Modern: Copenhagen Cycle Chic’s Mikael Colville-Andersen

[This article originally ran in Urban Velo magazine.]

As “The Pope of Urban Cycling,” Mikael Colville-Andersen is one of today’s leading bicycle advocates, but also one of the most controversial. He’s known as the kingpin of the stylish cycling movement via his award-winning photo blog Copenhagen Cycle Chic. The site mostly features candid photographs of attractive, well-dressed women on wheels, for a largely female readership. For his day job as CEO of Copenhagenize, a nine-person transportation consulting firm, he travels to cities around the world, advising politicians, planners and advocates on ways to emulate the success of the bike-friendly Danish capital.

Mikael’s blogs have a global following—Cycle Chic has inspired some 150 spin-offs in other cities. He’s also a sought-after public speaker who gave the keynote address at this year’s Pro Walk Pro Bike Pro Place conference in Long Beach, California. But he’s not without his critics. His outspoken opposition to helmet promotion troubles many North American advocates. And at least two female bike bloggers have critiqued his Cycle Chic aesthetic and rhetoric as being sexist, elitist and counterproductive for encouraging regular folks to ride.

In July I visited Copenhagen for the first time and, as advertised, it’s a biker’s paradise with mellow traffic, grade-separated bike lanes on all major streets and good-looking, stylish people on classy Dutch cycles everywhere you turn. I met up with Mikael, a bright-eyed, energetic man, at his flat in Frederiksberg, a town completely surrounded by Copenhagen. We sipped cans of Carlsberg as his young kids Felix and Lulu-Sophia practiced soccer and picked flowers in their lush back yard. Mikael and I discussed his views on helmets, the differences between Copenhagen and Amsterdam, why he’s underwhelmed by Portland, and why bikes should be marketed more like vacuum cleaners.

Why Clark Street in Lakeview wasn’t a protected bike lane: it’s 1 foot too narrow

CDOT responded today to my inquiry asking why Clark Street between Diversey Avenue and Addison Avenue received a buffered bike lane and not a protected bike lane. Bikeways planner Mike Amsden writes:

Clark Street (Diversey to Addison) was striped as a buffer protected bike lane, and not a parking protected bike lane, because it is a 51′ roadway throughout the project limits. As you might know, the minimum roadway width for installing barrier protected bike lanes on roadways with one travel lane and one parking lane in each direction is 52′, and the preferred minimum width is 58′. A 52′ roadway allows for a 5′ bike lane, a 3′ buffer zone, an 8′ parking lane and a 10′ travel lane in each direction. However, even when a roadway is 52′, other roadway characteristics and operational considerations must be assessed before installing parking protected bike lanes. These characteristics include the amount of bus, truck and bicycle traffic, loading and delivery needs of local businesses, emergency vehicle access and maintenance requirements.

These standards come from the NACTO* Urban Bikeway Design Guide. If you have not read this guide I recommend doing so as it will likely answer many other questions you may have. The guide can be found here. http://nacto.org/cities-for-cycling/design-guide/

To answer your final question, if we were to recommend a parking protected bike lane on a 51′ roadway, all curbside uses (parking, standing, loading, valet, etc.) would have to be eliminated on one side of the roadway for the entire stretch in order to do so.

1 foot is all it takes, it seems. You can see the relevant NACTO standard in this image. Notice items 4, 5, and 6, that describe the minimum widths for the bike lane, buffer area, and parking lane, respectively.

Update: Why can’t certain lanes be narrower?

Someone asked in the comments this question, which Amsden anticipated: “We can’t go with a 7′ parking lane because then you’d have a 7′ parking lane next to a 10′ travel lane. People wouldn’t be able to get out of their cars, buses/trucks wouldn’t be able to maneuver, emergency vehicle access would be restricted, etc. That’s why even a 52′ roadway (with a 8′ parking lane next to a 10′ travel lane) is considered really tight.”

Fall bike lane construction update

A Marking Specialists work truck in the Marshall Boulevard bike lane it just helped create (they work on weekends, too!). 

Chicago Department of Transportation staff and its contractor Marking Specialists have been busy this summer and fall, striping miles of conventional, buffered, and separated bike lanes in Chicago. This post documents all of the new bike lanes we haven’t yet featured prominently, some of which are likely still under construction as the photos were taken between 1 and 4 weeks ago.

Sacramento Boulevard, 24th Boulevard, Marshall Boulevard

Still to come on this project through Little Village, Lawndale, North Lawndale: Douglas, Independence, and Hamlin Boulevards. It connects with a short, separated bike lane on Jackson Boulevard between Independence Boulevard and Central Park Avenue. The Central Park Avenue bike lane then connects north to separated bike lanes on Lake Street and Franklin Boulevard. Collectively these bike lanes are called “West Side Boulevards”. I like how this new separated bike lane “goes places”: through and to residential neighborhoods, past schools and parks.

People parked their cars in the bike lane, which we’ve found to be typical for under-construction separated bike lanes. The pavement quality issues that Franklin Boulevard suffers from are present on this project as well, in multiple locations (there’s a small bush growing in the bike lane a few feet before your reach a large pothole). I look forward to seeing the ultimate design created at the intersections and high-speed curves in Douglas Park and the pavement issues corrected. This project is likely still under construction.

Might as well Jump! The CTA debuts a stepping-stone to bus rapid transit

[flickr]photo:8180431198[/flickr]

I’d been looking forward to riding the new J14 Jeffery Jump bus service for a few weeks now. It was a chance to participate in a small but significant turning point in the history of the CTA. The Jump is a new express bus along Jeffery Boulevard (2000 East) on the South Side, incorporating several elements of bus rapid transit (BRT) and hopefully paving the way for full-blown BRT downtown, on Ashland Avenue and/or Western Avenue within a few years.

In a nutshell, BRT brings buses up to subway-like speed via special infrastructure on the existing roadway, at a fraction of the cost of creating new rail lines. Ideally, BRT includes dedicated bus lanes, center running buses, stations in the median where customers pre-pay before boarding, traffic signals that turn green when a bus approaches and other features.

The Jump, funded by an $11 million Federal Transportation Administration grant, is essentially BRT lite, but it’s definitely a step in the right direction. Dedicated bus lanes only exist on a portion of the sixteen-miles Jeffery route, a two-mile stretch from 67th to 83rd Streets, and only during rush hours. From 7 – 9 am weekdays, parking is banned on the east side of the street to accommodate inbound bus traffic, and vice versa for outbound buses during the evening commute from 4 – 6 pm.
