Slide 1:
SafeStat

Slide 2:
What is SafeStat?
SafeStat is a data-driven analysis system that determines the current relative safety status of individual motor carriers 

SafeStat was developed at the Volpe Center for the Federal Motor Carrier Safety Administration (FMCSA)

Data used are maintained and managed at the Federal level by the FMCSA

Slide 3:
What Does SafeStat Do?
Evaluates and Scores Individual Motor Carriers in Four Safety Evaluation Areas (SEAs):
1. Accident
2. Driver
3. Vehicle
4. Safety Management

Slide 4:
SafeStat Design
Event and exposure data are used to calculate normalized measures for each carrier
Measures are ranked and assigned percentile values (Indicators) from 0-100-with 100 being highest or worst
Indicators are combined into SEA values
SEA values are weighted and summed to derive the SafeStat score

Slide 5:
SafeStat Hierarchy and Features
Carrier Safety Status (Overall & by SEA)
Normalized Measures
Severity-Weighting
Time-Weighting
Percentile Ranking
Data Sufficiency Tests
 
Top of Pyramid: SafeStat Score
SEA Values
Indicators
Safety Measures
Safety Event Data
Bottom of Pyramid: Carrier Descriptive Data

Slide 6: SafeStat Overview
MOTOR CARRIER SAFESTAT SCORE =
Data Sources by Carrrier + Measures and Indicators + Accident SEA results, Driver SEA results, Vehicle SEA Results, and Safety Management SEA results.

Slide 7:
How are SafeStat Scores Calculated
1. Motor Carrier Safety Data
2. Algorithm Calculates Safety Status of Carrier
3. Access SafeStat results for individual carriers via A&I Online. 

Slide 8:
FMCSA Compliance Reviews (CRs): 
Semiannually identifies and prioritizes carriers for on-site
  FMCSA compliance reviews 

PRISM Program:  
Identifies and monitors poorly performing carriers for the
  PRISM Federal/State safety improvement process (MCSIP)

Inspection Selection System (ISS):
Supports recommendations of evaluated carriers’ 
  drivers and vehicles for roadside inspections

A&I Online (www.ai.volpe.dot.gov)
Makes SafeStat results available via the internet to industry and the public to promote safety awareness and self-improvement

Slide 9: 
SafeStat Data
At the foundation of SafeStat are safety event data and exposure data
- Carrier specific safety event data reflect the carrier’s safety compliance and performance and include:
	- State Reported Crashes (last 30 mos.)
	- Recordable Crashes from CRs (last 12 mos. CRs) 
	- Roadside Inspection Violations (last 30 mos.)
	- Moving Violations (last 30 mos.) 
	- Compliance Review Violations (last 18 mos. CRs)
	- Closed Enforcement Cases (last 6 years)
- Exposure data normalize a carrier’s safety event data:
	- Number of drivers/vehicles and VMT 
	- Number of inspections

Slide 10:
SafeStat Categories for Scored Carriers

SafeStat evaluated carriers are assigned to Categories (A-G) based on their SafeStat Scores and SEA Values

SafeStat Categories for Scored Carriers
Category: A 
SafeStat Score Range: 350-550 >350 to <550
Includes SEA Values of 75 or Higher: All 4 SEAs, 3 SEAs that result in weighted score of 350 or more.

Category: B
SafeStat Score Range: 225-350 >225 to <350
Includes SEA Values of 75 or Higher: 3 SEAs that result in weighted score of less than 350. 2 SEAs that result in weighted score of 225 or more.

Category: C
SafeStat Score Range: >150 to <225	 
Includes SEA Values of 75 or Higher: 2 SEAs that result in weighted score less than 225.

Slide 11: Single-SEA SafeStat Categories 
Categories of carriers deficient in one SEA (SEA Value of 75 or higher)

SafeStat Categories for Carriers with One SEA Value
		
Single SEA Category: D	Specific SEA: Accident		SEA Value: 75-100
Single SEA Category: E	Specific SEA: Driver		SEA Value: 75-100
Single SEA Category: F	Specific SEA: Vehicle		SEA Value: 75-100
Single SEA Category: G	Specific SEA: Safety Management	SEA Value: 75-100

Slide 12: SafeStat Effectiveness Study
A study was conducted to confirm SafeStat effectiveness by comparing post-run crash rates for scored vs. unscored carriers:

(1) SafeStat was run 18 months in the past with data available at that time to identify and score carriers 
(2) Carriers with sufficient data were assigned to 3 groups based on the SafeStat run results: At-Risk (Categories A&B), Other Scored (Category C) and unscored
(3) Post-run crash rates for each group were observed and compared

Slide 13: Effectiveness Study Results
Carriers identified by SafeStat have higher crash rates than carriers not identified by SafeStat

Category A&B, At-risk, 52.0%
Category C: Other Identified, 29.4%
Not Identified: 24.6%
