In transportation infrastructure, a bidirectional traffic system divides travellers into two streams of traffic that flow in opposite directions.
Bus rapid transit (BRT), also called a busway or transitway, is a bus-based public transport system designed to have better capacity and reliability than a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or paying fares. BRT aims to combine the capacity and speed of a metro with the flexibility, lower cost and simplicity of a bus system.

Dual mode transit describes transportation systems in which dual-mode vehicles operate on both public roads and on a guideway; thus using two modes of transport.

A mobile lounge is a system for boarding and disembarking from aircraft using a bus-like vehicle.

The Oregon City Municipal Elevator is a 130-foot (40 m) elevator which connects two neighborhoods in Oregon City in the U.S. state of Oregon. It is the only outdoor municipal elevator in the U.S. and one of at least 8 in the world. The upper portion contains an observation deck which accounts for its flying saucer appearance.
A people mover or automated people mover (APM) is a type of small scale automated guideway transit system. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks.

A share taxi is a mode of transport which falls between a taxicab and a bus. These vehicles for hire are typically smaller than buses and usually take passengers on a fixed or semi-fixed route without timetables, but instead departing when all seats are filled. They may stop anywhere to pick up or drop off their passengers. Often found in developing countries, the vehicles used as share taxis range from four-seat cars to minibuses. They are often owner-operated.
A trackless train — or tram, road train, land train, parking lot train, Wattman trains, Deltrain, Dotto train or Choo-Choo train — is a road-going articulated vehicle used for the transport of passengers, comprising a driving vehicle pulling one or more carriages connected by drawbar couplings, in the manner of a road-going railway train. Similar vehicles may be used for transport of freight or baggage for short distances, such as at a factory or airport.

The Transit Elevated Bus (TEB) was a proposed new bus concept where a guided bus straddles above road traffic, giving it the alternative names such as straddling bus, straddle bus, land airbus, or tunnel bus by international media.
Trekschuit is an old style of sail- and horse-drawn boat specific to the Netherlands, where it was used for centuries as a means of passenger traffic between cities along trekvaarten, or tow-canals.
