The Comprehensive Transportation Network (CTN) compiles information from multiple sources and acts as the official source for roadway classifications and their defining characteristics in the full purpose city limits. The network also acts as a reference to other information, such as planned projects, transit routes, traffic volumes, accident volumes, projects in the city’s ETJ. The CTN is inclusive of all roadway classifications while keeping the geometry simple. It includes defining characteristics of the traveled way and streetside spaces.

The CTN can be used to provide a basis to map traffic volumes, perform Linear Referencing, plan and track progress for Complete Streets, identify Critical Arterials, and provide information to CAMPO for modeling.

The CTN was created by City of Austin Transportation Department Staff between 2017 and 2018 using ArcGIS software to compile information from multiple sources, including the Bicycle Master Plan, Urban Trails Master Plan, Sidewalks Master Plan, CodeNEXT, ASMP, and CapMetro's Connections 2025. The CTN is updated regularly, as update to the City's transportation infrastructure occurs.
