Highway Safety Manual Lead State Peer to Peer WorkshopNovember 17‐18, 2010 ,Schaumburg, Illinois
Data Needs and Other Background Knowledge
• Site Characteristics Data– Most characteristic data are available from Florida’s Roadway Characteristics Inventory (RCI) database
• Traffic Volumes– Traffic volume data are collected in the RCI
• Crash Data– Crashes are processed and location data are stored in a database managed by the FDOT Safety Office
Highway Safety Manual Lead State Peer to Peer WorkshopNovember 17‐18, 2010 ,Schaumburg, Illinois
Site Characteristics Data• Most characteristic data for the State Highway System
(SHS) (10% of all public roads) are available from Florida’s Roadway Characteristics Inventory (RCI) database
HSM Variables for Site Characteristics Florida RCI DataArea Type YesSegment Length YesLane, median, and shoulder information YesNumber and type of driveways NoCurve data YesGrade/Terrain YesRoadside Hazard Rating and other roadside data PartialLength and type of on‐street parking YesLighting YesIntersection number of legs YesIntersection traffic control YesIntersection turn signal phasing and signage NoIntersection skew angle YesIntersection sight distance No

Site Characteristics Data• SHS roads make up 10% of all public roads by centerline mileage, but carry over 50% of the total traffic each year and right at 50% of long‐form‐reported crashes

Traffic Volume Data• Traffic volume data are collected and estimated in the RCI for
roadways on the SHS
• Gaps and Local Road volumes are resolved using a combination of modeling processes and programmatic estimation

Crash Data• Crashes are collected by Dept. of Highway Safety and
Motor Vehicles (DHSMV) and locations are processed by the FDOT Safety Office

Actions Accomplished
• 408 Grant Funded (and using in‐house staff)– All Roads Base Map (GIS, Linear Referencing System (LRS), Crash Shapefiles, AADT)
– Working with partners and developing tools to promulgate use of common map
• Research– Safety Analyst (Safety Analyst Data Converter)– Calibration of HSM Equations and Development of SPF

Barriers/Challenges Encountered
• Quality and Availability of Local Road Data including:– Map line work– Traffic volumes (AADT)– Roadway characteristics
• Model Minimum Uniform Crash Criteria (MMUCC) compliance of Florida Traffic Crash Report forms
• Resources to process both Long Form (Fatal and Serious Injury Crashes) and Short Form (Property Damage Only) crash reports

Overcoming Barriers/Challenges• GIS line work (local roads):
Resolved using technology and staff to merge state base map with third party local road map
• AADT for local roads:
Resolved using a combination of modeling processes using adjacent land uses and parcel data paired with existing traffic counts in state inventory
Investigating processes for acquiring more accurate local information
• Roadway Characteristic data for local roads:
Investigating processes for acquiring more accurate local information
• New, more MMUCC‐compliant crash report form coming on‐line in 2011
• Investigating technology enhancements and resource‐sharing between FDOT and DHSMV to improve processing efficiency

Next Steps
• Initiate use of Traffic Safety Web Portal for data exchange
• Partner with local agencies to share available data on local roads by using the Traffic Safety Web Portal
• Work internally for data refinement for state roads
• Request FHWA data system evaluation

Conclusions
• Time and familiarity with the data and the data requirements will help facilitate implementation of the HSM. The more users we have that will use the methodology in the HSM, the better the availability and use of the data will be.
