Destination streets are rarely the best places to bike

This family took to riding on the sidewalk of Division Street instead of in the bike lane. They’re riding the stylish workhorse WorkCycles Fr8. Once I saw them riding the blue one, I had to get a different color. 

My friend Calvin Brown, a circumstantial urban planner, is always giving me Jane Jacobs-style observations about how citizens use their cities.

“Destination streets are the ones I avoid biking on because there’s so much car traffic there. Traffic must be balanced between streets that are good for biking and ones that aren’t currently good.”

In other words, because it’s a destination street (a place where there are a lot of retail outlets, venues, points of interest) it induces a lot of car traffic. Lots of car traffic discourages people from riding bikes, and makes it difficult for those who already are.

To me, a great example of this is Division Street. There’s a bike lane there from Ashland to California Avenues, and has tons (tons!) of restaurants and some night clubs. Yet that causes a lot of taxi traffic, people driving their own cars, looking for parking, jutting into the bike lane to see why traffic is going slow or backed up (um, because there are ton of cars!), and valet and delivery drivers blocking the bike lane.

It’s exactly this traffic, though, that keeps these places vibrant, desirable, and healthy (from an economic standpoint). The solution for bicycling is easy: swap the car parking with the bike lane so that bicycling isn’t affected by a majority of the aforementioned traffic maneuvers.

Calvin’s “destination streets” examples were Grand Avenue and Chicago Avenue. Neither has bike lanes, and both have 2 travel lanes in each direction. Grand has destinations from Racine Avenue to Ashland Avenue and Chicago has destinations from Ada Street to Western Avenue. I’d wager that if you narrowed those roadways by installing a protected bike lane you’d get slower traffic and higher business receipts.

Chicago Avenue at Hoyne Avenue is a particularly stupid part of Chicago Avenue: The Chicago Department of Transportation installed a pedestrian refuge island here. After several years and at least 4 replaced signs due to collisions of automobiles with it, the design hasn’t been modified. The island in and of itself did not change the speed of those who drive here, as the roadway’s width remained static.

Diversity in business and buildings

One of Jane Jacobs’ key points in her works tells about the need for diversity in neighborhoods: choices and options in housing, jobs, natural and gathering spaces, and entertainment.

One of Jane Jacobs’ key points in her works tells about the need for diversity in neighborhoods: choices and options in housing, jobs, natural and gathering spaces, and entertainment. As lives and lifestyles change, people aren’t forced to move or move out. Urbanophile touched on that in part two of “Building Suburbs That Last.”

This should sound familiar to you since it is exactly how Jane Jacobs described a healthy city neighborhood. She says it better than I ever could: “Flourishing diversity anywhere in a city means the mingling of high-yield, middling-yield, low-yield and no yield enterprises.” And, “Time makes the high building costs of one generation the bargains of a following generation. Time pays off original capital costs, and this depreciation can be reflected in the yields required from a building. Time makes certain structures obsolete for some enterprises, and they become available to others.”

I don’t believe that Jane’s discussions will convince any banker, economist or developer. For those arguments, you’ll have to refer to the rest of Aaron’s article on how smart, commercial land use development occurs in order to create sustainable suburbs. You should refer to paragraphs like:

If you having nothing but high value buildings, no one but national chains can afford to invest. If you have nothing but low value buildings, no one wants to. It is important to have a mixture of buildings, supporting a mixture of uses, mixture of high, medium and lower values uses, and both national chains (which bring much good with them) and indigenous business. It is this diversity that again helps to mitigate against the failure of any one element. And also provides room for the local business that is both committed to the town and a source of at least some independent economic life.

Where else does diversity give an advantage?
