ET3 Global Alliance is an American open consortium of licensees dedicated to global implementation of Evacuated Tube Transport Technologies (ET3). It was founded by Daryl Oster in 1997 with the goal of establishing a global transportation system utilizing car-sized cargo and passenger capsules traveling in 1.5m diameter tubes via frictionless superconductive maglev.

The expressways of Japan make up a large network of controlled-access toll expressways.

The Autobahn is the federal controlled-access highway system in Germany. The official German term is Bundesautobahn, which translates as "federal motorway". The literal meaning of the word Bundesautobahn is "Federal Auto(mobile) Track".

The Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. Hyperloop is described as a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could potentially convey people or objects at airline or hypersonic speeds while being energy efficient compared with existing high-speed rail systems. This, if implemented, may reduce travel times compared to train and airplane travel over distances of under approximately 1,500 kilometres.

The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. Construction of the system was authorized by the Federal Aid Highway Act of 1956. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico.

A modal share is the percentage of travelers using a particular type of transportation or number of trips using said type. In freight transportation, this may be measured in mass.

A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft.

Japan has a nationwide system of national highways distinct from the expressways. The Ministry of Land, Infrastructure, Transport and Tourism and other government agencies administer the national highways. Beginning in 1952, Japan classified these as Class 1 or Class 2. Class 1 highways had one- or two-digit numbers, while Class 2 highways had three-digit numbers. For example, routes 1 and 57 were Class 1 highways while 507 was a Class 2 highway.

A transport network, or transportation network is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. Examples include but are not limited to road networks, railways, air routes, pipelines, aqueducts, and power lines. The digital representation of these networks, and the methods for their analysis, is a core part of spatial analysis, geographic information systems, public utilities, and transport engineering. Network analysis is an application of the theories and algorithms of Graph theory and is a form of proximity analysis.

The railway network of Sardinia includes lines that develop for a total of about 1,038 km in length, of which 430 km with an ordinary gauge and about 608 km narrow gauge, with an average density of 43 m of rail per km2, a figure that drops to 25 m/km2 considering only public transport lines.

Transmetro, officially, Sistema Integrado de Transporte Masivo de Barranquilla y su Área Metropolitana, is a mass transit system that has operated in the city of Barranquilla, Colombia since April 7, 2010.
