Our Commitment

FHWA is committed to addressing these issues:

• States have difficulty combining crash, roadway, traffic and other data for the best analysis.
• States need assistance in improving the quality of their Crash and Roadway Data
• States often don't know where to start in setting Goals/Plans for Data Improvement
• We (and states) don't always know what states need in these areas

Current Products
and Tools

• Model Inventory of Roadway Elements (MIRE)
• Fundamental Data Elements Guidance (FDE)
• MIRE Management Information System (MIRE MIS)
• Crash Data Improvement Program (CDIP)
• Roadway Data Improvement Program (RDIP)
• Cost Benefit for Data Investment
• Capability Assessment

 

MIRE

• First version published in 2010
• List of over 200 roadway data elements:
  • Definition
  • Attributes to describe
  • Priority rating (critical or value-added)
• Part of analytic tool or HPMS Provides a consistent state of practice and standards for roadway data formatting

MIRE-MIS

Companion effort to MIRE to develop adoptable model of data information system

Lead Agency Program (NH & WA)

• Data Format Evaluation
• Promote expansion of MIRE data elements being collected
• Performance Measures of Characteristics

 

CDIP and RDIP

Technical Assistance Programs to assess State Crash/Roadway Data Processes and Systems

Recommendations for Data Improvement provided to the State in a Summary Matrix on the issues of data:

• Timeliness
• Accuracy
• Completeness
• Consistency
• Integration (linkages)
• Accessibility (sharing)

 

Cost Benefit of Data Investment

Planned to determine cost benefits for investing in Data Systems and Processes

Scaled Investment Benefit Methodologies

Assist decision-makers in weighting benefits of data investment against other investments

 

Capability Assessment

Develop State capability baselines Work with States to identify desired goal capability level

Assess national capability and identify national gaps Determine opportunities for national leadership & programs, Develop a National action plan.

Work with States to develop State-specific action plan frameworks Identify available resources and peer exchange in 2012-2013.

How can States get involved?

• Sign up for Capability Assessment to gauge your States level of data-driven capability
  –(where are we? what can we do with what we have now?)
• Take advantage of CDIP/RDIP Technical Assistance to evaluate your crash and roadway data collection program along critical dimensions
  – (how do we improve what we have?)

 

Summary

FHWA is committed to:

• Ensuring that States can combine crash, roadway, traffic and other data for the best analysis.
• Helping States to Improve their Roadway Data
• Helping States to Set Goals/Plans for Data Improvement
• Listening to What States' Need in these Areas
