Description: The Arizona Transportation Information System (ATIS), also referred to as the All Roads Network, is a spatial file that represents the centerlines of all roads in Arizona. All roads open to public travel are included but the file may also include administrative (i.e. service) roads, private roads, and other roads restricted from the public. This layer is submitted in the annual Highway Performance Monitoring System (HPMS) federal report in the All Roads Network of Linear Data (ARNOLD) spatial dataset.
All event layers describing road designations and attributes, such as functional system and speed limit, refer to ATIS to identify the route ID and measure locations for the features on the road network.
