SRTS California Network Meeting
Overview
• Introduction to TIMS– SWITRS
– SWITRS Query & Map Tool
– SWITRS GIS Map
– Future Plans
Statewide Integrated Traffic Records System (SWITRS)
• All reported collisions on public roadways in California
• Maintained by California Highway Patrol (CHP)
• Approximately 200,000 injury collisions each year
• http://iswitrs.chp.ca.gov
Transportation Injury Mapping System (TIMS)
• Provides data and mapping analysis tools and information for traffic safety related research, policy and planning.
• Free account application, open to everyone
• http://tims.berkeley.edu
SWITRS Query & Map Tool
• Data query focused application– Quick results, quick refresh
• One page summary statistics
• Download collision, party, victim files
• Google Maps collision display– 5,000 collisions limit
– Collision points clustered until zoomed in
Collision File
SWITRS GIS Map
• Map-centric collision viewing with other data layers (census tracts, TAZ, schools, etc.)
• Same collision query UI as Query & Map tool
• 500 collisions display limit
• Focused collision spatial selection tools– Drawing
– Buffer (intersection or corridor)
– Region (TAZ, census tract, zip code)
Future Plans
• Party and victim fields query
Future Plans
• 2009 SWITRS
• Minor injury collisions added to database
• SHSP challenge area specific queries
• Improved state highway geocoding process
Funding Acknowledgements
• Funding for this site was provided by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
Interactive Geospatial PDF Maps
• PDF Maps of each city/county in California
• Map Contents– Ped-bike collisions
– Schools
– SRTS funding status
• Identify schools and collisions; show data table
Upcoming Seminar
• Utilizing Safe Routes to School Pedestrian and Bicycle Collision Maps
• Date: Wednesday, May 4, 2011Time: 10:00 a.m. – 11:30 a.m. PDT
