Comprehensive Biking and Walking

San Diego Regional Bike and Pedestrian Counts

The San Diego Regional Bike and Pedestrian Counter Network is one of the largest in the country. The network was initially funded by a grant from the Centers for Disease Control and Prevention and is a collaborative effort between SANDAG, San Diego State University, and the County of San Diego Health and Human Services Agency.

Across 15 jurisdictions in the San Diego region, 54 counters have been installed at 37 sites. Placement of counters was determined in consideration of regional bikeways in the 2010 Regional Bike Plan, smart growth place types using the Regional Smart Growth Concept Map, and socioeconomic factors. Data is collected every 15 minutes and uploaded daily to the Eco-Counter website.

To allow for a robust analysis of biking and walking behaviors, there are three types of counters in operation – some count people biking, others count people walking, and some count both people walking and biking. SANDAG is currently exploring how this data could support ongoing transportation performance monitoring efforts.

The initial network was installed in 2012 and is in the early stages of development. Daily maintenance and management of the network is needed to make sure counters are properly functioning and data is as accurate as possible. Although counters are strategically placed, they do not count every biking and walking trip made in the region.

The counter data provides one way of understanding general trends in biking and walking over time and provides an indication of where people bike and walk most frequently. SANDAG is collecting other relevant data on biking and walking, and developing analysis tools to better understand trips made by bike and on foot, to provide a more complete picture of active transportation in the region.
