▪ Distresses Examined Based on Pavement Type

Data Collection Methodology

▪ Automated* ‘One Van’ Solution

• Laser Crack Measurement System (LCMS)

• Surface distresses

• Pavement imagery

• ROW Panoramic Imagery

• Mobile LiDAR

▪ Pavement Skid Testing

• Subcontracted

What is LCMS?

▪ Laser Crack Measurement System (LCMS)

• Mobile-based Automatic* Pavement Distress Detection

• Double Laser Sensor Array

• One Inventory, Many Outputs

• Pavement Management System Tool

4/12/201811

What Comes Out of LCMS

▪ One Inventory, Many Outputs

• Pavement Management

4/12/201812

• Transverse Profile • Joint Faulting

• Sealed Cracks • Alligator Cracking

• Transverse Cracks • Longitudinal Cracks

• Bleeding • Raveling

• Potholes • Macro Texture

• Rutting • International Roughness Index (IRI)

What Comes Out of LCMS

▪ One Inventory, Many Outputs

• Safety Features

• Inventory Features

4/12/201813

• Longitudinal Grade • Cross Fall

• Horizontal Curvature • Pavement Markings

• Foreign Object Debris (FOD)

• Pavement Width • Pavement Length

• Pavement Type • GPS Tagging

• Linear Referencing (DMI)

How LCMS Works▪ Sensors Detect Two Primary Attributes:

• Range: Distance between sensor and ground

• Intensity: Laser intensity (Black or White)

What Come from LCMS?

4/12/201818

▪ *Not Everything!

▪ Distress Selector Application

• Used to extract additional distresses

Why LCMS?▪ Speed

• Can operate at normal traffic speeds (up to 60 MPH)

▪ Accuracy• Millimeter level crack detection capability

▪ Repeatability• Consistent and Reliable Results

▪ Day or Nighttime Operation• Efficiency

▪ Safety• Crews not dodging cars

4/12/201819

Post Processing Workflow

▪ Defined LCMS Database Schema

▪ Existing Processing Tools & Applications

• Field Data Checker

• XML Data Loader

• LiDAR GPS Loader

• Distress Selector

▪ New Workflows

• Pub 336 Distress Export

• Merging of ROW Imagery with Pavement Data

4/12/201820

Data Conflation

▪ LCMS Data & Panoramic Conflated to LRS

• ~262K LCMS Data Points

• ~246K Image Points

4/12/201821

Uh-Oh…▪ Inconsistencies in Data

• YoY IRI Data

• Disparate Quantities

▪ Why?

LRS Calibration!Solution: Recalibration

Lessons Learned

▪ LRS Matters!

▪ Result: PTC LRS Business Process Summit

• 2-Day Meeting on LRS in January 2018

• GIS, Engineers, IT, Consultants

• Define/document workflows for LRS-GIS updates

• Define how “source of truth” data will be maintain across systems
