National Highway Planning Network (NHPN)
The NHPN is a 1:100,000 scale network database that contains line features representing just over 450,000 miles of current and planned highways in the US, consisting of interstates, principal arterials, and rural minor arterials, by State.
Oak Ridge National Highway Network
The ORNHN is a database of major highways in the US that is based on the NHPN, and is designed primarily to address vehicle routing and scheduling problems, but may be used in other studies that require an analytic or geographically-based national highway network. The database has been enhanced by the addition of more roads and attribute detail and adjusting topology to produce a true analytic network.
Oak Ridge National Laboratory Rail Network
The Center for Transportation Analysis (CTA) Railroad Network contains every railroad route in the US, Canada, and Mexico that has been active since 1993. Geographic accuracy is generally 100 m on active lines. Supporting data on interlines and corporate ancestry allows the construction of routable networks for a specific target date. The network is an extension of the Federal Railroad Administration's strategic network.
