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
Typical Current State at Roads and Highways Agency Multiple Linear Referencing Systems (LRS) Challenges Business information remains in silo Data not easily accessed by other systems Latency in propagation of updates Other Systems Traffic Bridge Many business systems, each w/ unique LRS Road Inventory Challenging or expensive integration Safety GIS not well integrated leading to limited spatial capabilities across enterprise Pavement Enterprise GIS
Target State Unified Linear Referencing Platform Benefits Common, consistent location reference across all business systems HPMS Capital Planning Business Intelligence Maintenance Desktop Web Mobile Bi-directional data flow Data can be consumed by different systems Integration simplified Standards for system design & procurement Esri Roads and Highways Esri LRS environment supporting Ref Mkr., MilePoint, and all other LRMs GIS can serve many systems and functions Expanded spatial capabilities across enterprise ArcGIS System Other Pavement Bridge Safety Traffic Roadway Inventory Misc. Business Systems
Esri LRS Solution History
Esri Roads and Highways Drivers 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
Common Implementation Challenges Reported by agencies attempting to implement LRS Solutions during last 10 years* 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 *Includes non-esri implementations
Why Advanced LRS? Esri customers asked for it 42 State DOT s, 1,000 s of Cities/Counties use Esri Solutions
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
Traditional approaches to multiple LRMs LRM 1 LRM 2 LRM 3 Multiple Route Geometries LRS Transformed Measures in Event Tables LRS 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 Line events may be split Before Realignment After Realignment
Move Preserves Location M doesn t change XY may change Line events are never split Before Realignment After Realignment
Retire Preserves Location and Position M and XY don t change Line events are never split Event goes away Before Realignment After Realignment
Snap Preserves Proportion M, XY and route may change Line events are not split Event self-adjusts to new alignment Before Realignment Stay Put Move Snap
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
Configuring the ALRS Demo
Managing Workflow
What is a Workflow? Projects Activities Web Tasks Mobile Desktop
Esri Roads and Highways Workflow Create a Project Add a Redline Update Network Verify Results Publish Data Road Inventory User Road Inventory User Linear Network Maintainer QA/QC Staff GIS Supervisor
Esri Roads and Highways Solution Workflows Out-of-the-box Workflows: Add Planned Route Calibrate Route Cartographic Realignment Create New Road Lengthen Route Merge Routes Realign Gap Route Realign Overlapping Route Realign Route Reassign Route Retire Route Reverse Route Widen Route Workflows will need to be configured according to DOT needs
