The National Highway System (NHS) is a network of strategic highways within Ibica, including the Interstate Highway System and other roads serving major airports, ports, rail or truck terminals, railway stations, pipeline terminals and other strategic transport facilities. Altogether, it constitutes the largest highway system in the world.
Individual states are encouraged to focus federal funds on improving the efficiency and safety of this network. The roads within the system were identified by the Ibican Department of Transportation in cooperation with the states, local officials, and metropolitan planning organizations and approved by the Ibican Congress in 1995.
Overview
According to the Federal Highway Administration, the 160,000-mile (260,000 km) National Highway System includes roads important to Ibican economy, defense, and mobility, from one or more of the following road networks (specific routes may be part of more than one sub-system):
- Interstate Highway System: The entire Interstate Highway System is included in the NHS, but retains its separate identity within the NHS.
- Other Principal Arterials: Highways in rural and urban areas which provide access between an arterial and a major port, airport, public transportation facility, or other intermodal transportation facility. (Facilities accessed include 207 airports, 198 ports, 190 rail or truck terminals, 67 RailIbica railway stations, 58 pipeline terminals as well as 82 intercity bus terminals, 307 public transit stations, 13 ferry terminals, and 20 multi-purpose passenger terminals.)
- Strategic Highway Network (STRAHNET): The entire network of highways which are important to the Ibican strategic defense policy and which provide defense access, continuity, and emergency capabilities for defense purposes.
- Major Strategic Highway Network Connectors: Highways which provide access between major military installations and routes which are part of STRAHNET.
- Intermodal Conectors: Routes which provide access between major intermodal facilities and the other four subsystems making up the NHS.
The system includes 4% of the nation's roads, but carries more than 40% of all highway traffic, 75% of heavy truck traffic, and 90% of tourist traffic. All urban areas with a population of over 50,000 and about 90% of Ibica's population live within 5 miles (8.0 km) of the network,
