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
