UPDATE ON CENTRAL PARKWAY CRASH STATISTICS

Reference Document #201600266
The Committee at its session on February 29, 2016 referred the following item for review and report.
MOTION, dated 2/18/2016 submitted by Councilmember Smitherman, I MOVE that
the City Administration remove the protected bike lanes from the 1600 block to
2000 block on Central Parkway. (STATEMENT ATTACHED)

BACKGROUND
In July 2014 the City installed protected bicycle lanes along Central Parkway between Elm Street and
Marshall Avenue. There are currently over 213 protected bicycle lanes in the United States. Protected
bicycle lanes use a physical barrier such as planters, curbs, parked cars or posts to separate and buffer
bicycle and automobile traffic, versus a traditional bicycle lane which utilizes a 4-inch white paint
stripe.
STATUS
Changing any street from full-time parking to rush-hour restricted parking does require an adjustment
in drivers’ behavior and expectations. However, the number of crashes between the 1600 block and
the 2000 block of Central Parkway (Liberty Street to Ravine Street) is comparable to similar streets
citywide. In 2015 there were 62 crashes recorded for this segment of Central Parkway, and 7 of those
crashes involved parked cars. A detailed analysis of Police Crash Reports indicates that of those 7
crashes, 2 crashes resulted from drivers in the left lane losing control of their vehicle and veering into
the right lane; 1 crash was the result of a driver with a medical emergency who crossed the double
yellow line; and 4 crashes were the result of drivers in the right-hand/parking lane who hit parked
cars. 1 of these 4 crashes is suspected to be alcohol related.
The table below compares Central Parkway to two other major arterials of similar length, land use mix,
and traffic volume, with two travel lanes in each direction and rush-hour restricted parking.

 Again, a detailed review of Crash Reports indicates that of the 62 crashes recorded for this section of
Central Parkway in 2015, 19 were the result of drivers who rear ended a vehicle in the left-hand/travel
lane, 11 crashes resulted from improper passing, 7 crashes were the result of drivers who failed to
yield when turning across an intersection, 6 crashes involved drivers who ran red lights, 6 crashes
were logged as taking place on Central Parkway but actually took place on side streets, 4 crashes were
the result of drivers who failed to maintain control of their vehicle, 4 crashes were rear ends that took
place in the right-hand/parking lane, 2 crashes were rear ends at traffic lights, 1 crash was the result
of a driver running a stop sign, 1 crash was the result of an illegal U-turn, and 1 entry was a duplicate
report.

Based on initial community feedback, the City installed new pavement markings on Central Parkway in
May of 2015 to help remind motorists that they may encounter parked cars in the lane adjacent to the
protected bicycle lanes. The 18-foot-tall markings read, “CAUTION PARKED CARS” (see attached
photo).
The markings were installed on Central Parkway between Liberty Street and Brighton Place, where onstreet parking is allowed all day adjacent to the bicycle lane except 7 to 9 a.m. in the southbound lane
and 3 to 6 p.m. in the northbound lane. Outside of rush hours, through motorists are encouraged to
use the left-most lane, as cars may be parked in the lane adjacent to the protected bicycle lane.
Since the additional pavement markings were installed, DOTE has observed two positives changes.
First, more cars are parking in the parking lane, making it more obvious that it is a parking lane, which
will help drivers adjust their expectations and stay more alert. Second, more drivers appear to be
utilizing the left-most travel lane – indicating a better understanding of the street design.
SUMMARY
The number of crashes on Central Parkway is comparable to the number of crashes on similar streets.
Research published in the American Journal of Public Health showed that streets with protected bicycle
lanes saw 90 percent fewer cyclist injuries per mile than those with no bicycle infrastructure. Given the
reduced risk of injury to bicyclists, the Administration does not recommend removal of the bicycle
lanes. However, DOTE will continue to monitor conditions, and improvements may be made in the
future as best practices evolve.
