Launching an Automated Active Transportation Data Collection System in San Diego, CA

Time: November 08, Friday, 1:40 p.m. – 3:00 p.m.
Location: 1605 Tilia, Room 1103, West Village
Speaker: Dr. Sherry Ryan, Professor, School of Public Affairs – Graduate Program in City Planning, San Diego State University

This talk will describe one region’s efforts to link active transportation performance monitoring to regional transportation planning by establishing a network of automated bicycle and pedestrian count stations along the proposed regional bicycle network, which was recently adopted in the San Diego Association of Governments (SANDAG) 2050 Regional Transportation Plan. The implementation of this counting program grew out of collaboration between the County of San Diego Health and Human Services Agency (HHSA), San Diego State University (SDSU) public health and city planning researchers, and active transportation planning professionals at SANDAG.

The count station siting methodology employed a multi-step process where the regional bicycle network was segmented, and then stratified sampling employed to select a subset of bicycle network segments where counters would be installed. The siting methodology first established a comprehensive network of count stations representing ultimate coverage of the regional bicycle network (76 count stations). Then a subset of representative locations was selected for phase one count program implementation (35 counts stations). To date count equipment has been installed at 26 locations and the remainder is expected to be installed by November 2013. When fully implemented, this counting program will be one of the most comprehensive automated data collection systems of any region in the US
