PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

Driver behavior is key:• Primary factor in two-thirds of crashes• Contributing factor in more than 90% of

crashes• Hardest to study; the thing we know the

least aboutOpportunity - Naturalistic Driving Study (NDS):• Miniaturized sensor technologies and

increased computing capacity: can observe real-world driving

• Crash, pre-crash, near-crash, and “normal” driving data

Safety: Strategic Rationale

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

SAFETY: Naturalistic Driving Study & Roadway Information Databases

NDS Data

RID (GIS)

Data from 3,542 volunteer drivers and their vehicles in six sites using passenger cars, vans, SUVs, pickups

New data collected 12,500 centerline miles consistent

across six sites. Acquired data (DOTs, others) on 200,000 centerline

miles with varying conditions: roadway, weather, traffic ..

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

What is in the NDS Data Set?

• Demographic Questionnaire• Driving History• Driving Knowledge• Medical Conditions and Meds• ADHD Screening• Risk Perception• Frequency of Risky Behavior• Sensation Seeking Behavior• Sleep Habits• Visual, Physical, and Cognitive Test

Results• Exit Interview

Participant Assessments

• Make, Model, Year, Body Style• Vehicle Condition• Safety and Entertainment Systems

Vehicle Information

• Face, Forward, Rear, and Instrument Panel Video

• Vehicle Network Data• Accelerometers/Gyros, Forward

RADAR, GPS• Additional Sensor Data

Continuous Data

• Characterization of Trip Content• Start Time and Duration of Trip• Min, Max, Mean Sensor Data• Time and Distance Driven at Various

Speeds, Headways• Vehicle Systems Usage

Trip Summary Data

• Crashes, Near Crashes, Baselines• 30s Events With Classifications• Post-Crash Interviews• Other Crash Data

Event Data

• Subset of participant drivers• Call time and duration• Call type (text, call, pic, etc)

Cell Phone Records

• Matching trip GPS to roadway database

• Roadway classifications• Other roadway data

Roadway Data

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Four data sources:– Newly-collected mobile van data– ESRI GIS information– State roadway inventory data– Supplemental data: weather,

work zones, safety campaigns, FRA at-grade railway crossings

• Will allow for driver behavior to be associated with physical environment on 12,000 centerline miles

Roadway Information Database (RID)

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Formal advisory committee• Chaired by Joe Schofer, Northwestern U.• Main recommendations:– Take a phased approach– First phase of 4-5 years as experimental

period– Develop user communities– Look at potential long-term, sustainable

technical and institutional structures

• Agreement among primary partners that TRB should manage Phase 1

Long Term Stewardship Committee

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• MOU among FHWA, AASHTO, NHTSA, TRB

• 5-year Cooperative Agreement between FHWA and TRB

• It is an experimental, proof of concept phase to work out data access procedures, value of the data, and to determine a long-term operations and data access plan.

Phase I Implementation Program

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Safety Data Oversight Committee: establishes policies

• Expert Task Groups– Data Access: data availability and technical

issues – User Community Development: communication

and the needs of the user community

• TRB staff: manage committees and contracts; conduct studies and background research

• National Academies of Sciences Institutional Review Board: Oversight of human subjects protection procedures

Phase I Oversight and Governance

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Virginia Tech Transportation Institute– Houses and manages the NDS data base– Makes NDS data available through Data Use

Licenses, contracts with data users, and data set preparation

– Manages InSight Web site– Manages a secure data enclave for viewing of

personally identifiable information

• INTRANS at Iowa State University– Houses and manages the RID data base– Makes the RID data base available to users

• TBD: – Confidentiality disclosure risk assessment– Identification of low-risk public use data sets

Phase I Contractor Roles

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• FHWA– Funds 11 test users under the Implementation

Assistance Program (IAP) – Establishing the Safety Training and Analysis

Center (STAC) • To train and assist selected users • Pilot site for a second secure data enclave

• AASHTO Safety Task Force– Monitors the IAP tests– Provides feedback to TRB and FHWA on the

Safety data program

Phase I Partner Roles

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Types of data available :– 5.41M trip summaries – 4,250 crash/near crash events– 32,500 baseline events– Processed variables for radar, alcohol sensor,

etc.– Roadway database linking variables

• ~1000 registered users of InSight web portal– 80% from US internet domains – 10% from European countries– 10% from the rest of the world – 50%+ from academia

InSight Web Portal

PHASE 1 OF SHRP 2 DATA IMPLEMENTATION & OVERSIGHT

• Behavior on curves• Rural intersections• Speed limits, roadway

geometry, and driver behavior

• Closely-spaced freeway interchange ramps

• Roadway departure• Animal/vehicle collisions• Behavior in work zones• Behavior in inclement

weather• Driver

distraction/inattention• Speeding; Road rage; Driver

fatigue; Seatbelt use• Autonomous vehicle safety

systems• Vehicle safety defects• Crash risk and driver health• Fuel economy and vehicle

operating costs• …

• FHWA, NHTSA• State DOTs• Universities: professors,

graduate students• Auto manufacturers• Insurance company• Hospital• National Institutes of Health• …
