The Hampton Roads Region
  • Located in SE Virginia with over 1.6 million
    residents
  • Region includes 10 cities, 6 counties, and 2
    transit agencies
  • Economy driven by the military, ports and tourism
  • Diverse transportation system connected with
    tunnels, bridges, and ferries

3
Regional Safety Study
  • In 2001, HRPDC initiated the task of producing a
    Regional Safety Study
  • Safety study objectives
  • Collect, organize, and create a regional crash
    database with GIS capabilities
  • Analyze and identify high-crash locations for the
    region
  • Develop and examine solutions to address safety
    problems
  • Recommend safety projects for inclusion in the
    Transportation Improvement Program
  • Few other MPOs were publicly involved with safety
    planning at that point

4
Data Collection State Level
  • General Crash Data
  • Virginia Traffic Crash Facts
  • Released yearly by Virginia DMV
  • Contains general crash data ( of crashes,
    injuries, and fatalities) for each locality in
    Virginia

5
Data Collection State Level
  • Detailed Crash Data
  • Virginia DOT maintains a database of all traffic
    crashes statewide with either a fatality, at
    least one injury or property damage of least
    1,000
  • Only records for crashes in counties and on the
    interstate system contain location information

6
Data Collection Local Level
  • Due to limitations of statewide crash data,
    detailed crash data needed to be collected from
    each city in the region
  • Each major city maintained a database of citywide
    crash data
  • Departments maintaining databases vary among
    cities from local police department to traffic
    engineering and public works

7
Regional Database
  • Created regional crash databases for all
    interstate segments and major at-grade
    intersections included in the CMS network
  • There were many difficulties developing the
    regional crash database
  • Different methodologies from city to city
  • Different database formats from city to city
  • Not every city had crash data for all three years

8
Data Analysis
  • Interstate segments and intersections were
    analyzed ranked using both crash frequency and
    Equivalent Property Damage Only (EPDO) crash
    rates
  • Used EPDO crash rate per million VMT for
    interstates
  • Used EPDO crash rate per million entering
    vehicles for intersections

9
The Report
  • The Hampton Roads Regional Safety Study is broken
    into three parts
  • Part I General Crash Data and Trends
  • Part II Interstate and Intersection Crash
    Findings
  • Part III Crash Analysis and Countermeasures
  • Report available at http//www.hrpdc.org/publicat
    ions/techreports/transportation.html

10
Rural Safety
  • HRPDC recently completed a study examining
    roadway safety in the rural areas of the region
  • Includes those areas not included in the Regional
    Safety Study
  • Jurisdictional crash data and trends
  • Crash locations and countermeasures

11
Data Issues MPO Perspective
  • Statewide crash data does not include locations
    of crashes within the non-Interstate roadways in
    the Cities.
  • Crash data is obtained in CD form, which is not
    available until many months into the following
    year
  • No GIS-related connection available

12
Data Issues VA Perspective
  • Not all downstream information is captured
    (citation info, medical results)
  • The process of collecting crash reports is
    cumbersome, with substantial manual effort
    necessary to enter and correct information
  • Data entry is handled by several departments
    within multiple agencies
  • There is a significant backlog of reports
  • Data is not directly accessible by all
    stakeholders

13
Safety Improvement Efforts
  • The Virginia Safety Management System (SMS)
    Committee was established as a result of ISTEA in
    early 1990s.
  • The purpose of this committee was to integrate
    and coordinate all transportation safety-related
    programs.
  • One goal of the SMS Committee is to create and
    maintain a high-quality, integrated data system
    for evaluation and analysis.
  • New Charter created the Surface Transportation
    Safety Executive Committee in 2005 as a result of
    SAFETEA-LU

14
Safety Improvement Efforts
  • Surface Transportation Safety Committee
    membership
  • DMV
  • VDOT
  • VSP
  • Commission of the VA Alcohol Safety Action
    Program
  • Department of Health (EMS)
  • NHTSA
  • FHWA
  • Federal Motor Carrier Safety Administration
    (FMCSA)
  • Department of Education
  • Virginia Transportation Research Council
  • Department for the Aging
  • Department of Rail and Public Transportation
  • Hampton Roads Planning District Commission (MPO)

15
Safety Improvement Efforts
  • Traffic Records Assessment conducted by NHTSA in
    July 2005
  • HRPDC and City of Norfolk participated
  • Key findings
  • Improve roadway data to capture incident location
    for all jurisdictions
  • Improve capture and input efficiency of crash
    data
  • Create full driver and vehicle history files
  • Improve EMS and trauma data systems and
    integration
  • Link citation data create a DUI tracking system
  • Strengthen the role of the Traffic Record
    Coordinating Committee (TRCC)
  • Prepare and implement a traffic records strategic
    plan

16
Safety Improvement Efforts
  • The Virginia Strategic Highway Safety Plan is a
    statewide coordinated plan to meet current safety
    challenges in the following emphasis areas
  • Driver Behavior
  • Special Users
  • Safety Conscious Planning
  • Roadway Departures
  • Intersection Safety
  • Pedestrian and Bicycle Safety
  • Work Zone Safety
  • Traffic Records
  • The five-year comprehensive, data-driven plan
    will integrate the four Es engineering,
    education, enforcement, and emergency medical
    services.

17
Safety Improvement Efforts
  • Crash Outcome Data Evaluation System (CODES)
  • Effort to link existing statewide traffic records
    with injury outcome and charge data to support
    highway safety decision-making at the local,
    regional and state levels.
  • Cooperative agreement between the Virginia
    DMV/Governors Highway Safety Office and the
    National Highway Traffic Safety Administration
    (NHTSA).

18
Safety Improvement Efforts
  • The Traffic Records Electronic Data System
    (TREDS) is being created to address a variety of
    safety data issues
  • TREDS planning and oversight is done by the
    Traffic Records Coordinating Committee, which
    includes a wide range of stakeholders
  • DMV
  • VDOT
  • FHWA
  • Medical Community
  • Funding is being provided by DMV VDOT
  • State and Local Police
  • VCU and UVA
  • HRPDC

19
TREDS Benefits
  • Streamline and simplify data collection for law
    enforcement
  • Increase the efficiency and data quality by the
    use of automated edit checks
  • Provide the ability to process police reports
    electronically including automated submission to
    DMV
  • Eliminate data entry by multiple state agencies
    of the same crash report

20
TREDS Benefits
  • Have data in a flexible architecture to address
    different analysis and report needs
  • Enable all stakeholders to easily access the data
    and crash reports via the Internet
  • Ability to link crash data with downstream data
    (e.g. medical and citation data)
  • Eliminate manual data entry backlogs

21
TREDS Timeline
  • Currently completing the functional requirements
    portion of the process
  • Solutions review will commence this month
  • TREDS is expected to be partially functional
    sometime in 2008, with full implementation in
    2009
