2The 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
3Regional 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
4Data 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
5Data 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
6Data 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
7Regional 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
8Data 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
9The 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
10Rural 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
11Data 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
12Data 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
13Safety 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
14Safety 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)
15Safety 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
16Safety 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.
17Safety 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).
18Safety 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
19TREDS 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
20TREDS 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
21TREDS 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
