About the network dataset

The HERE GIS Data Suite network dataset uses ArcGIS Network Analyst® technology and incorporates turn restrictions, one-way restrictions, relative elevation data, access restrictions for different vehicle types, and time and length cost attributes. A modified time cost attribute is also supplied that reflects the generally slower traffic conditions in urban areas. Directions configured for the network dataset include alternate street names and signpost directions.

The network dataset includes height, weight, length, and width parameterized restrictions where available from HERE. Additional turn restrictions, transport preferred routes, and truck speed limits are available for transport vehicles and built into network dataset attributes.

The network dataset contains HERE historical traffic patterns and allows analyses to run for a specified time and day of the week. Free-flow and average travel times are derived from traffic data. This edition of the network dataset also includes travel times based on speed limits. For information about historical traffic in ArcGIS Pro®, see Historical traffic.

The network dataset in the HERE GIS Data Suite FGDB is NETWORK_ND, found in the NETWORK feature dataset. The feature classes Routing_Streets, Signposts, and Network_Turns define network dataset elements and are part of the NETWORK feature dataset. A number of tables supports the network dataset, including Signpost_Streets, TimeZones, and for traffic products, Streets_DailyProfiles, DailyProfiles, and Streets_TMC.

You can run network dataset analyses through ArcGIS Network Analyst®. The Time Slider toolbar can display time slices of historical traffic data.
