Book excerpt: The objective of this Texas Department of Transportation (TxDOT) research project was to develop guidance materials on intermediate access to a buffer-separated toll lane. To develop the material, researchers gathered other state guidelines, reviewed the literature, and recorded operations at five intermediate access sites. From videotapes of the sites, characteristics of approximately 8400 vehicles that moved into or out of the managed lane were recorded. Examples of the characteristics measured included where the vehicle entered or left the lane (early, within the opening, or late) and the lane of origin for the vehicle. Volume counts for 5-minute periods were associated with each maneuver.
