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

Benefits

Target State

Unified 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 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

LRS

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
