Utah Data Advancements Electronic delivery of all crash records Assign geo-location for all crashes since 2010 Collection of roadway assets via LiDAR inventory Develop Safety Index for comparing safety on public roads Develop two HSM-based Bayesian models with BYU for network screening Implement usRAP model for conditions-based risk assessment

The Problem Scattered data; we had the parts, just needed to put it all together for fast, easy, effective consumption.

Crash Query Data exploration Query creation Countermeasure identification Intersection analysis Reporting Hot Spot identification

Countermeasure Identification Automation of Countermeasure Suggestion Consistency in statewide analysis Provide ideas to new analysts/designers Simplify query process

Algorithm Examples Dilemma Zone Detection Curve Delineation Shoulder Rumble Strips Occurred at Intersection AND 2+ Vehicles Involved AND Angle, Head-On, or Rear-End AND Vehicle 1 Maneuver is Straight AND Posted Speed >= 45 mph Did NOT Occur at Intersection AND Alignment = Curve AND Head-On or Sideswipe Opposite OR Roadway Departure Did NOT Occur at Intersection AND Roadway Departure AND Single Vehicle

Network Screening Network screening Corridor safety analysis Statewide ranking Statewide comparison

Safety Analysis Project-specific analysis Crash distribution analysis Route safety comparison Countermeasure selection Benefit-cost calculation

Inform Enable users to understand and analyze crash data Example 1: Maintenance Staff Identify Black Ice Trouble Spots Example 2: Engineers Using Crash Data During Design

Educate Educate regarding the use and interpretation of data Example 1: Highway Patrol Using Data to Target Enforcement Example 2: Officers Begin to “Own” the Data

Support Decision Making Empower instantaneous data-driven decision making Example 1: Providing Instant Answers to Legislature Example 2: MPO and Local Government Decision Making
