1. UDOT SafeMap hosted by Numetric

2. 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

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

4. Demo

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

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

27. 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

28. Network Screening Network screening Corridor safety analysis
Statewide ranking
Statewide comparison

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