Data collected from an annual street condition survey is used to classify the street condition where the streets rated fair to excellent are considered satisfactory (and everything below fair is unsatisfactory).
The measure's outcome reflects the ratio of satisfactory lane miles in the City's street inventory to the total number of lane miles in the City's street inventory. This measure is also a Key Performance Indicator for the Austin Transportation and Public Works Department (TPW), which means that it helps TPW gauge the quality of City's street network, identify priority areas that need work, and take data-informed decisions on keeping the street network in serviceable conditions.
This dataset is collected and compiled by the Street and Bridge Operations division under the Austin Transportation and Public Works Department. The measure time period is on an annual fiscal year basis.
Calculation: Ratio of satisfactory (fair to excellent) lane miles in the City's street inventory to the total number of lane miles in the City's street inventory.
