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 AgencyMultiple 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

Benefits
Target StateUnified Linear Referencing ‘Platform’
• Common, consistent location reference across all business systems
• Bi-directional data flow
• Data can be consumed by different systems
• Integration simplified
• Standards for system design & procurement
• GIS can serve many systems and functions
• Expanded 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 GISo Is configurable for DOT specific workflowso 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

LRS
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
Roads and Highways Data Model
Data Model
• Based on Esri Roads & Highways model• Supports Advanced Linear Referencing
- Multiple LRMs- Dynamic Features- Location Management- History
• Extends to client data requirements• Loosely coupled with business data

Add a Redline
• Out-of-the-box Workflows:• Add Planned Route• Calibrate Route• Cartographic Realignment• Create New Road• Lengthen Route• Merge Routes• Realign Gap Route
• Workflows will need to be configured according to DOT needs
• Realign Overlapping Route• Realign Route• Reassign Route• Retire Route• Reverse Route• Widen Route
