Safety and Asset Management (data):A Natural SymbiosisHeather Rothenberg, PhD FHWA Office of SafetyConference on Transportation Asset ManagementSan Diego, CAApril 2012
We 3 data.So we all want more!
More data is always good.Right?
If we can’t afford to maintain the data, isit worth collecting at all?Attendee at GIS Peer Exchange, 2011
Share data.Leverage limited resources.
FHWA Office of Safety Data ProgramsRoadway Safety Data Program (RSDP): CapabilitiesAssessmentsModel Inventory Roadway ElementsValue of Investment in Data
Model Inventory Roadway Elements(MIRE)andMIRE Management Information Systems (MIRE-MIS)
MIRE: What and Why? Listing of roadway and traffic elements critical tosafety management Provides data dictionary – definition, attributes,etc. Enable user to merge roadway and traffic datawith crash data to enhance data analysiscapabilities.www.mireinfo.org
Data Element Example129. Intersecting AngleDefinition: The measurement indegrees of the smallest anglebetween any two legs of theintersection. This value willalways be within a range of 0 to90 degrees.Attributes: DegreesPriority: CriticalHPMS/Tool Requirements:HSM/IHSDM (Required)
Supplemental Data Sets Roadside fixed objectsSignsSpeed dataAutomated enforcement devicesLand use elements related to safetyBridge descriptorsRailroad grade-crossing descriptorsSafety improvements
