The Seattle Department of Transportation (SDOT) today released data for the new Second Avenue Protected Bike Lane that shows bicycle ridership has tripled due to the new facility. With the conversion of the former one-way bike lane to a two-way, protected bike lane, an average of 1,099 bicyclists a day used the new lane on September 9, 10 and 11 according to electronic counters. This is three times the daily number of cyclists that had previously used the former one-way bike lane.
“I am pleased that the new Second Avenue bike lane is addressing Seattle’s need for a safer, more predictable route through downtown,” said Mayor Ed Murray. “These changes help enhance safety for everyone and make Seattle better prepared for the launch of Pronto! Cycle Share in October.”
Installed by SDOT, the facility opened Monday, September 8 with new pavement markings for two-way bike traffic, green pavement markings where turning cars cross the bike lane, separate traffic signals for bicyclists and motorists turning left, and plastic posts separating the bike lane from the left turn/parking lane.
SDOT and the Cascade Bicycle Club teamed up for an education/outreach campaign, and staff was positioned at left turn locations to remind motorists and bicyclists to observe the signals. Based upon feedback obtained during the initial few days, SDOT made additional changes on September 11 to reduce confusion. “No turn on red” signs replaced “turn on green arrow only” signs and a green straight arrow replaced the solid green circle light. After these changes, an observation of 52 vehicles on Second Avenue at Spring Street revealed that only two drivers made an illegal left turn when their left turn arrow was red, a 96.2 percent compliance rate.
“A better organized Second Avenue means a more predictable roadway for cyclists, drivers and pedestrians, and makes it safer for all users,” said SDOT Direct Scott Kubly. “Signals and signs make the rules of the road more clear.”
Since the bicycle lanes opened, travel times for drivers on Second Avenue have been better than originally forecasted. On the first day of the bike lane’s operation, it took drivers approximately one minute longer to travel the 0.71 miles on Second Avenue than before the conversion. With numerous events occurring that first week, to include opening day of the National Football League season at CenturyLink Field, engineers expect travel times to decrease further as drivers become accustomed to the new roadway configuration.
