This study presents a dataset of scheduled intercity bus services from 72 operators in the United States. The dataset is available as a large GTFS feed as well as a simplified GeoJSON suitable for mapping. An interactive ArcGIS map of the dataset is available online. We summarize statistics by operator and state, list the 10 most frequent intercity routes, and compare our dataset to the Intercity Bus Atlas (ICBA) provided by the Bureau of Transportation Statistics (BTS). Important methodological decisions and limitations of the dataset are discussed.
