FHWA MIRE Management Information System (MIS)
Nancy Lefler, VHB August 30, 2012
Overview • Background• Purpose• Overview of Activities– Data Collection– Structure of MIS– Performance Measures
• Results/Products • Questions
Project Team • Prime – Vanasse Hangen Brustlin, Inc. (VHB)
• Supported by – Applied Research Associates (ARA), Data-Nexus, Inc.,
UNC-Highway Safety Research Center, Dr. Forrest Council
• FHWA – Robert Pollack and Dr. Carol Tan
Background
Background – MIRE • MIRE – Model Inventory of Roadway Elements • Listing of roadway and traffic elements critical to
safety management• Data dictionary – definition, attributes, etc.
www.mireinfo.org
Next Step – MIRE MIS • Evolution of MIRE from listing to Management
Information System (MIRE MIS)
Purpose• Determine feasibility of MIRE data management
system:– Mechanisms for data collection– Process for data handling and storage– Linkage among files– Performance metrics
• Provide lessons learned/guidance for safety data improvement
Overview of Project Activities
Collection of data elements
Development and testing of MIS structure
Development/expansion of performance measures
Collection
Collection of MIRE Data Elements Research: current practices and gap analysis Lead Agency Program: pilot MIRE data collection“Collective Data” concept MIRE Data Collection Guidebook
Lead Agency Program• Pilot MIRE data collection• New Hampshire DOT and Washington State DOT • Developed an intersection inventory
Data Collection Process1. Determine what elements
to collect2. Develop detailed Work Plan3. Develop data collection tool – Model to extract and pre-
populate– User interface
4. Populate inventory5. Conduct QA/QC
Data Collection
Data Collection: Results/Products
• Intersection inventory for NHDOT and WSDOT
• Final Report: Document development of tool and lessons learned
Collective Data Concept • Assembling data or collecting
information using a large group of people (think Wikipedia)
• Agencies putting concept into practice• Explore how this concept can apply to
collecting roadway information • Result: Collective Data White Paper
MIRE Data Collection Guidebook • Guidance on collecting the MIRE elements.• Focus on elements that do not have established
collection methodologies.• Includes for each element: – Description– Accuracy parameters– Considerations– Existing resources – Methodologies– Concerns
Structure
MIS Structure
• Develop overall structure • Develop of prototype • Test prototype • Refine structure
Structure of the MIRE MIS • Decision support system to improve highway
safety• Developed using relational database model• Integrate data from disparate sources for higher
level analysis
Lessons Learned• Data quality matters! • Using MIRE as guidance - States build system
around their own data structure• GIS is an essential part of the MIRE MIS -
consistent referencing system for data points
Performance Measures
Performance Measures • Tools for measuring data quality and establishing
goals for data improvement • Six primary metrics: – Timeliness– Accuracy– Completeness– Uniformity– Integration– Accessibility
Roadway Inventory Metrics• NHTSA developed initial performance measures
for the six core traffic safety data systems• Built/expanded on those metrics• Detailed review of metrics proposed for roadway
data• Metric related business practices – how to use
metrics to improve data • Result: Performance Measures Report
Results/Products
Summary of Project Activities/Products • Collection of MIRE data elements:– Collection Mechanisms and Gap Analysis Report – MIRE Pilot Data Collection Report – Intersection inventory datasets for NHDOT & WSDOT – Collective Data White Paper – MIRE Data Collection Guidebook
• Development and testing of MIS structure:– Prototype for pilot agency – Report on structure and lessons learned
• Performance Measures:– Performance Measures Report
Summary • MIRE MIS – how to collect, integrate, manage,
and measure data for improved safety decisions • State and local agencies can realize benefits
• Products available on website: www.mireinfo.org
