Overview of Highway Data
What is Esri Roads and Highways?
• Enterprise data management
• Integrated framework for maintaining highway data
• Simplifies LRS management
• Streamlines editing workflow
• Provides tools for communicating highway changes
• Automates the synchronization with business layers
Challenges
Typical Current State at Roads and Highways Agency
Multiple Linear Referencing Systems (LRS)
• Business information remains in silo
• Data not easily accessed by other
systems
• Latency in propagation of updates
• Challenging or expensive integration
• GIS not well integrated leading to
limited spatial capabilities across
enterprise

Esri LRS Solution History
• Business Drivers:
• Support expanded adoption of Esri software within DOTs
• Provide end-to-end Linear Referencing System (LRS) Solution that:
o Supports multiple types of users – non-GIS and GIS
o Is configurable for DOT specific workflows
o Integrates well with DOT sub-systems
Esri Roads and Highways Drivers
Common Implementation Challenges
• Closed data model (Black Box)
• No open API’s
• Do not support DOT processes/workflows
• Tied to vendor-specific business systems
• Requires extensive Oracle DBA expertise in-house
• Limited vendor implementation and support resources
• Many implementations abandoned
Reported by agencies attempting to implement
LRS Solutions during last 10 years*
*Includes non-Esri implementations
Esri customers asked for it
42 State DOT’s, 1,000’s of Cities/Counties use Esri Solutions
Why Advanced LRS?
Roads and Highway Concepts
Advanced Linear Referencing
• Multiple LRMs
• Dynamic Routes
• Location Management
• Time Aware LRS
• Redlines
Multiple Linear Referencing
Methods
What is an LRM?
• Means of locating features along a route
• Consists of both a measure and a route ID
• Based on length of highway
- Susceptible to change when highway changes
- Can be managed in the ALRS
• Multiple LRMs are supported
• Can be Interpolative or Referent
Types of LRMs
• Interpolative
• Referent
Multiple Linear Referencing Methods
• Reference
Markers
• Project
Stationing
• Mile Posts
• Road Inventory
LRS
Traditional approaches to multiple LRMs
• Multiple Route Geometries
• Transformed Measures in
Event Tables
• Reference Datum

Dynamic Route Representations
Dynamic Route Representations
• Support multiple definitions of
a highway
• Routes are defined in the data
model
• Centerline features
• Route table
• Sequence Table
• Real features managed as
tabular data
• Lives only in the map
Location Management
Esri Roads and Highways manages location
• Controls priority between
location and position
• Location is a measure
along a route
• Position is an XY
coordinate on a map
Event Behavior
• Controls what happens when
network geometry changes
• Rules are configured for each
event layer
• Each layer can have different
rules based on type of edit
• Behavior rules focus on what
is preserved rather than what
has changed
Stay Put
• Preserves Position
• XY doesn’t change
• M may change
Before Realignment
After Realignment
• Line events may be
split
Move
• Preserves Location
• M doesn’t change
• XY may change
Before Realignment
After Realignment
• Line events are never
split
Retire
• Preserves Location
and Position
• M and XY don’t change
Before Realignment
After Realignment
• Line events are never
split
• Event goes away
Snap
• Preserves Proportion
• M, XY and route may
change
• Line events are not
split
• Event self-adjusts to
new alignment

Time Aware LRS
Time Aware LRS
• Present – We need to see the current
state of our highways
• Past – We need to see what our highways
looked like when incidents occurred
• Future – We need the ability to add
planned highways to our data
Before view of the highway. All events display on the current alignment.
After view of the highway. Events on the original alignment are either retired or snap to the new alignment according to their behavior rules. Events downstream have moved. When rolling backward and forward in time, events must automatically adjust to the alignment vintage according to their behavior rules.
Redlines
Communicate using Redlines
• Mark-up feature to illustrate
desired network changes
- Has measure values and route
reference
- Geometry need not be accurate
- Provides a template for making
edits
• Indicates where work has
been done
• Optional; useful but not
required
