The Pima Association of Governments and the Tucson-Pima County Bicycle Advisory Committee are seeking volunteers to help with the fifth annual bicycle and pedestrian count.

The information is used in applications for bicycle friendliness ratings from the League of American Bicyclists, to detect shifting trends, to find out where infrastructure is used and where it may be needed.

Volunteers simply count the number bikes and pedestrians passing by in a two-hour morning rush-hour period, and again for two hours during an afternoon rush hour. The shifts don't have to be on the same day, but the count is designated for certain times in October.

Anyone wishing to participate must attend a training session, detailed on the website link above.

Volunteers can choose their dates and location from which to count.

The 2011 bicycle and pedestrian count showed about 15,900 bicyclists and 23,600 pedestrians. The data showed 73 percent of bicycle riders were male, and 50 percent did not wear a helmet. There were 14 percent more bicyclists counted in 2011 than the year before at the same locations.
