ArcGIS Network Analyst

ArcGIS Network Analyst is a powerful extension that provides network-based spatial analysis including routing, travel directions, closest facility, and service area analysis. ArcGIS Network Analyst enables users to dynamically model realistic network conditions, including turn restrictions, speed limits, height restrictions, and traffic conditions, at different times of the day.

ArcGIS Network Analyst uses an advanced Network Data Model that allows for the use of realistic datasets encompassing multiple attributes such as cost, restriction, and hierarchy. You can define various cost attributes, such as distance, time, and visibility, according to their analysis requirements.

Features of the Network Data Model include

• Complex, multipart turns
• Dynamic impedance
• Global weights
• Exact and hierarchical routing
• Network barrier support
  

With ArcGIS Network Analyst, you can conduct Drive-time analysis Point-to-point routing Route directions Service area definition Shortest path Optimum route Closest facility Origin-destination analysis ArcGIS Network Analyst provides a rich environment with easy-to-use menus and tools as well as the robust functionality available in the geoprocessing environment for modeling and scripting. All software users who need high-quality, GIS-based routing and network analysis can leverage ArcGIS Network Analyst. Industries that benefit from ArcGIS Network Analyst include transportation, logistics, health care, public safety, education, utilities, local government, business, and many more. See examples.
