The Los Angeles County Bicycle Coalition and Los Angeles Walks, pedestrian advocacy group, are looking for volunteers to help conduct the biannual Los Angeles Bicycle and Pedestrian Count.

In 2011, LACBC and LAW counted more than 15,000 bicyclists and some 75,000 pedestrians in the city of L.A.—well above the 2009 count of 14,000 bicyclists and 62,000 pedestrians, according to the Los Angeles Walks website. The 2013 Los Angeles Bicycle and Pedestrian Count is scheduled on Tuesday, Sept. 10 and Saturday, Sept. 14 at more than 100 locations across the city.
