## SafeStat

## 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

## 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**

## 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**

## SafeStat Overview

**SafeStat Overview**

**MOTOR CARRIER SAFESTAT SCORE**

**Data Sources by Carrier**

## How are SafeStat scores calculated?

**How are SafeStat scores calculated?**

**1. Motor Carrier Safety Data**

- Carrier Registration

- Crashes

- Compliance Reviews

- Roadside Inspections

- Closed Enforcement Cases

- Moving Violations

**2. Algorithm Calculates**
**    ****Safety Status of Carrier**

**3. Access SafeStat**
**    ****results for **
**    ****individual carriers**
**    ****via A&I Online.**

## Uses of SafeStat

- 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

-  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

## 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

## SafeStat Categoriesfor Scored Carriers

**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**_

- Categories of carriers deficient in one SEA (SEA Value of 75 or higher)

_**SafeStat Categories for Carriers with One SEA Value**_

**Single-SEA ****SafeStat Categories**** **

## SafeStat Effectiveness Study

**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

## Effectiveness Study Results

- Carriers identified by SafeStat have higher crash rates than carriers not identified by SafeStat
