Last week there were some questions related to the special bike track in the middle of Pennsylvania Avenue, in Washington DC.
I have found the video (click on the link and watch), where Gabe Klein, the former Commissioner of Transportation for DC and Chicago talks about the 2-way protected bike track.
The bike track was installed in 2010, at the center of Pennsylvania Avenue, where the streetcar used to run.This kind of center-running design has been never implemented anywhere else before.
After the first year there was a 200-300% increase in a.m and p.m peak hours volumes along the bike track based on the data provided by the DC Department of Transportation.
The number of cyclists increased during the peak hour periods from 15-25 to 150-170 cyclists. (The number of cyclists already increased year by year before the installation, but their number increased more rapidly after the bike lane was completed. **Caution should be used in making direct comparison between the counts, as data collection was made during different seasons.)
At the same time, the number of cars decreased by 14-21%.
The bike lane improved the Level of Service (Danish Bicycle LOS model) experienced by cyclists from level E (poor) to level C (average).
The number of people who were at least "a little satisfied" increased from 20 to 60%.
In 2015 additional wheel stops were installed along the bike tracks to provide further separation from cars and avoid cars to make U-turns through the central bike lanes.
The benefits of the bike lane:
1. Clear point of view of the entire street from the middle of the road
2. Avoid being in the curbside where cars turn right
3. Speed up cycling (no parking cars, no bus stops, no pedestrians in cyclists' way)
The disadvantages of the bike lane:
1. Poor visibility of the signals from further distance
2. The width of the bike lanes: originally designed with 1-1 car-sized lane, later the width of the bike lanes were narrowed down (to maintain car space), which reduced safety for bikers.
3. The problem at the refugee islands between pedestrians, traffic poles and cyclists
