Strategic Highway Safety Plans (SHSPs)
Data-driven statewide plan
Vision
Innovation
•Establishes a common vision, mission and goals to save lives on all
public roads
•Identifies a State’s key transportation safety needs and guides
investment decisions
•Prioritizes strategies with the greatest potential to reduce fatalities
and serious injuries
•Developed in collaboration with a broad range of stakeholders
•Multidisciplinary addressing 4 Es of Safety
• Determines measurable performance targets

Benefits of Safety Data
• Use of integrated roadway, traffic, and crash
data in analysis can lead to more efficient
use of funds and improved safety

MAP-21 on Safety Data Systems
• States shall have in place a safety data system
sufficient to guide the Highway Safety
Improvement Program (HSIP) and Strategic
Highway Safety Plan (SHSP) processes, including:
– Safety problem identification and countermeasure
analysis
– Identification of hazardous locations
– Strategic and performance-based goal setting
– Advancing capabilities for safety data collection,
analysis and integration
7
System Requirements – Roads Coverage
• HSIP applies to all public roads
• Data to be collected from:
State owned/maintained roads
Non State owned/maintained roads
Roads on tribal lands
Public roads on Federal lands
8
System Requirements – Types of Data
• Safety data are used to identify hazardous locations,
sections and elements on all public roads by location
• Safety data to be collected for all road users includes:
– Crash data
– Roadway data
– Traffic data
– At RR grade crossings, highway and train traffic
• Diverse data sets should be able to be linked or
integrated
9
System Requirements – Geolocation of
Safety Data
• Crash, roadway and traffic data should be linkable
by geolocation to a basemap that is inclusive of all
public roads within a State.
• August 7 2012, Memorandum on Geospatial
Network for All Public Roads requires states to
update LRS networks to include all public roads by
June 15, 2014
10
Subset of Model Inventory of Roadway
Elements (MIRE) to be Collected
• MAP-21 required the establishment of a subset of
MIRE elements that are useful for roadway safety
• Subset enables jurisdictions to analyze crash
experience of roadway networks relative to the
expected average crash frequency given roadway
and traffic characteristics at specific locations
11
Subset of Model Inventory of Roadway
Elements (MIRE) to be Collected - Cont
• For roads > 400 AADT subset includes:
– Road segment elements
– Intersection elements
– Interchange/ramp elements
• For roads < 400 AADT subset includes:
– Road segment elements
– Intersection elements
12
MAP-21 Eligible Safety Data Collection,
Analysis, and Improvement Activities
• “Highway safety improvement projects are
defined as strategies, activities and projects on a
public road that are consistent with a State’s SHSP
and correct or improve a hazardous road location
or feature or address a highway safety problem.”
• Collection, analysis and improvement of safety
data is specifically identified as an eligible project
within the definition of a HSIP
13
Implications for State Safety Data
Systems
• Not collecting data for data’s sake
• Optimal safety investment decisions
• Improvement in safety programs through
improved analysis methods (e.g., HSM)
• More effective deployment of safety resources
• Follow-up rulemaking to further address safety
data requirements
