ArcGIS Roads and Highways Server

With ArcGIS Roads and Highways Server, you can do the following:

Publish networks and event layers as a map service

Using ArcGIS Roads and Highways Server, you can publish your LRS Networks and registered event layers as a map service. As a map service, your linear referenced data can be shared to the enterprise and published to your organizational account at ArcGIS Online. Networks and events can be consumed by any client app that can consume an ArcGIS Server map service, including existing ArcGIS Desktop web and mobile clients. In addition, web developers can use the ArcGIS Server Web APIs to develop web and connected mobile apps against your linear referenced data.

Compatibility with desktop solutions

Use the following details to install and maintain desktop clients that are compatible with your Roads and Highways Server installation.

Compatibility with ArcMap

ArcMap, including the ArcGIS Roads and Highways Desktop extension, and ArcGIS Enterprise, including the Roads and Highways Server extension, must be the same version to be compatible. For instance, if the desktop version is at 10.8.1, then enterprise must also be version 10.8.1.

Compatibility with ArcGIS Pro

The Roads and Highways functionality in ArcGIS Pro requires Location Referencing services available from ArcGIS Enterprise. ArcGIS Pro and ArcGIS Enterprise must be installed to compatible versions.


The Roads and Highways functionality is included in ArcGIS Pro and does not require a separate installation but requires the Location Referencing license feature.

Use the following matrix as a guideline:

Add the Linear Referencing capability to map services

Linear Referencing capability

Roads and Highways Server extends the existing ArcGIS Server map service with an additional REST service capability for linear referencing. These additional REST services, provided by Roads and Highways Server, support the following capabilities:

  • Provide LRS-based network and event layer information
  • Translate coordinate locations to routes and measures
  • Translate (Locate) routes and measures to coordinates or polylines
  • Validate route and measure values
  • Convert measures from one LRM to another
  • Multilayer, transactional event editing, with support for overlap retirement and coincident event merging

Roads and Highways provides online developer help for the Roads and Highways REST services exposed by the Linear Referencing capability.

Provides JavaScript web developer samples

Roads and Highways sample web apps

To demonstrate the pattern of use of the REST services exposed by Roads and Highways Server, the server product comes packaged with JavaScript developer samples. These developer samples demonstrate how a web or connected mobile developer would do the following:

  • Visualize networks on a map
  • Visualize events on a map
  • Locate measures on a route
  • Perform spatial and attribute queries for routes
  • Perform spatial, measure, and attribute queries for events
  • Convert routes and measures to coordinates
  • Convert coordinates to routes and measures
  • Convert measures between linear referencing methods (LRMs)

Roads and Highways provides online hosted versions of these developer samples.
