What does an intuitive bike lane or other street marking mean?
It means that the street user can reasonably (yeah) guess, and guess right, what they’re supposed to do.
For bicyclists in Chicago, the lack of bike lane markings that continue to the edge of an intersection (often demarcated at the stop bar) creates an unintuitive bike lane design.
At intersections, an intuitive bike lane design would mean that the bicyclist and the motorist know where and how to position their vehicles in respect to the other, even if there isn’t a car there yet, or there’s not a bike there yet. Many intersections in Chicago that have protected bike lanes do this; especially the ones with separate signal phases. And these intersections work really well for bicyclists: they stand safely away from motorists, and motorists don’t attempt to occupy these spaces.
But currently at dozens, if not hundreds, of Chicago intersections where the bike lane drops before the intersection, you’ll see bicyclists behave and maneuver in several ways, none of which are accommodated by the street’s design.
Some people will bike between two lanes of cars to the front of the line, and when they get there, lacking a bike box or advanced stop line, they’ll stand with their bike in the area between the crosswalk and the stop bar. If the first car is over the stop bar, then people will usually stand with their bike on the crosswalk.
Others will bike between a lane of cars and the curb to get to the front of the line.
Others will wait to the side of drivers, and other still will wait behind a line of cars, putting themselves at a major time disadvantage as the people who biked up to the front. Not to mention they’ll choke on more fumes.
Then, when the light turns green, motorists behave differently. Some will follow behind the first bicyclist, while others will try to pass but closely because they’re essentially sharing a lane side-by-side – this exerts a lot of mental stress on the bicyclist.
Where the city has built space that’s absolutely not to be shared (meaning it’s for the exclusive use by people bicycling), then the designs are substandard because they still allow or seem open to driving. Otherwise, though, space for cycling that’s “part time” is only usable space for those holding the most power and not for the people riding bikes who need it.
These deficiencies in Chicago’s bike lane network are often the result of failing to make, or make well, space for cycling from space used for parking or turn lanes.
This is 2015 and we continue to “not make space for cycling” despite every policy that calls for making bicycling in Chicago safe and convenient so that more people will do it. It’s just that in the unwritten policies it says that you can implement that policy if it doesn’t impede driving*.
* The City of Chicago has built many road diets (a reduction in the number of travel lanes) in the last four years, and some before that. A few of these have worked well for bicyclists, like on 55th and Vincennes where they built protected and buffered bike lanes, respectively (and Dearborn through the Loop).
I put road diets in a note after “impede driving” because they’re only done where they also won’t make local traffic more congested on that street or an intersecting streets.
On the face of it, that’s exactly what many people believe they’ll do because a road diet removes or converts lanes and that’s seen as the same as reducing car capacity which will shift that car traffic to other streets. That pretty much doesn’t happen and the city only implements road diets on streets that have MORE capacity than is used.
