From the 2012 Report:
Background: This first annual report, the 2012 City of Alexandria Bicycle and Pedestrian Count Report, summarizes pedestrian and cycling trends at selected locations in the City of Alexandria. This collection of non-motorized traffic data supplements data on motorized traffic to provide a more complete picture of travel behavior as inputs to the City's transportation planning efforts.
Extrapolation of counts conducted indicate a 14% increase in Alexandria's active transportation (bicycling and pedestrian together) for 2012, compared to 2011, including a 25% increase in cycling in Alexandria in 2012 to 2.5 million annually at 12 count locations. Two of the top 5 bicycle traffic locations were "on-street" locations, suggesting that in addition to filling the gaps in our “green crescent” trail network, what is needed are more bike lanes and protected bike lanes to connect residences to transit, jobs, shopping, schools and other destinations.
There was a 6% increase in pedestrian traffic in Alexandria in 2012 to 3.1 million annually at 12 count locations, with the highest counts observed on Cameron and Prince Streets west of Washington Street. The relative low count of bicyclists in these two locations suggest that installation of bike lanes and /or cycle tracks on these streets would provide more effective East-West bicycle transportation corridors through Old Town.
Annual counts from 2011 to 2012 showed a stable gender distribution of cyclists at 27-28% female cyclists observed. Studies suggest that concerns for cycling safety are greater among women than men and likely contribute to the observed gender distribution of cyclists in Alexandria. Bicycling infrastructure improvements that emphasize safety, such as protected bike lanes, are expected to increase the amount of cycling and also the percentage of female ridership in Alexandria. That said, traffic-protected off-street bike paths alone will be insufficient; what is needed is a network of protected facilities leading "to the supermarket, the school, [and] the day care center".5
