City of Madison, WI Crash GIS
Short term Crash GIS Goals Intended as a 3 year pilot project to develop a working crash GIS. Automate “pin” mapping of crashes Automate diagramming of intersection crashes Speed transfer of crash data to users Enhance crash data query capabilities Increase staff efficiency Work more directly with other local agencies (Madison Police, Dane Co. Sheriff)

Automated Crash Diagram Westbound Crashes prior to test. BIG SKY/TREE/MINERAL POINT WAS THE HIGHEST CRASH FREQUENCY INTERSECTION IN THE CITY FOR 1998
Westbound Crashes after test.
Original Data Flow
Potential Savings with interdepartmental cooperation New World DB Data Corrected WisDOT DB TE Data Ready for use Step Eliminated ? Changed Stakeholders: Traffic Engineering, Police, WisDOT
Possible New Data Flow Data on all three database the same with only one entry instead of four. 1)Officer 2)911 center 3)TE 4)WisDOT 5)Public via internet
Traffic Engineering Data Entry Sheet Initially created to clean up location data. A step towards automated data entry by a police officer. Automates input of 16 data fields in current MV-4000
Automated Entry-Select Location by Intersection Name
Automated Entry-Select Location using GPS coordinates
Enhanced Query Capabilities Query by fields coded in MV-4000 Examples of queries include Red Light Running, Alcohol, crash frequency
Red Light Running Crashes CRASHES RANKED BY FREQUENCY FOR A 13 YEAR PERIOD
MADISON 1999 PEDESTRIAN CRASHES
Current Status Automate “pin” mapping of crashes-completed Automate diagramming of intersection crashes- preliminary only Speed transfer of crash data to users-turnaround is improved, but we are not yet to a web based system Enhance crash data query capabilities-completed Increase staff efficiency-already substantial improvement, more yet is possible Work more directly with other local agencies (Madison Police, Dane Co. Sheriff)-yes
Web based crash data query Automate crash location and reporting by Police Officers using aerial photos, GIS or GPS Electronic MV-4000 Badger TraCS Long term Crash GIS Goals
Other Data Collection Efforts Pocket PC-Based Seat belt survey Coordinated and funded by WisDOT/BOTS
