According to Donn Fichter,18 PRT is a system of small public automated transport vehicles (designed to carry three to six passengers per vehicle) operating on a specially designed transportation network for cost-effective and faster services. It caters to optimizing an individual’s transportation needs for low and medium density living areas without owning a vehicle – a modern trend of the millennial. Figure 3.4 shows such a vehicle displayed in an auto show. Several PRT systems have been designed but many have not yet been delivered due to constant changes in technological paradigms. Politico-economic agreements at the local and state government level are important.19 Key parameters of PRT, also called automated guideway transit (AGT), are optimum location of transit hubs away from large transportation systems such as seaports/airports, railway/subway stations, etc. The hubs, away from population concentration (urban and suburban) centers, also called last mile, are optimally located for efficient frequency of operation (office hours as well as out of hours). The PRT system is similar to other concepts, such as short transportation from the busy city center (BCC) to the so-called suburban parking district (SPD) or the transportation hub.

Personal Rapid Transit (PRT) is a public transportation mode featuring small automated vehicles operating on a network of specially-built guide ways. PRT is a type of automated guide way transit (AGT), a class of system which also includes larger vehicles all the way to small driverless subway systems. In PRT designs, vehicles are sized for individual or small group travel, typically carrying no more than 3 to 4 passengers per vehicle. The guide ways are arranged in a network topology, with all the stations located on sidings, and with frequent merge/diverge points. This approach allows for nonstop, point-to-point travel, bypassing all intermediate stations. The point-to-point service has been compared to a taxi (transportation idea, which means picking up passengers from the place where they stay at the beginning of the journey and taking them directly to the destination point).
Automated vehicles

PRT vehicles are types of automated vehicles that travel on a separate and new infrastructure. Typical PRT vehicles (sometimes called pods) under development are golf cart–sized, motorized enclosures that normally hold up to four people and bicycles or luggage. There are a number of schemes that utilize a guideway from which the pods get their power. Figure 11.3 illustrates one such concept [15]. Guideways can be miniature rails, monorails, or paved surfaces with buried wires for tracking. Generally, the vehicles run on rubber tires. Some have sliding power connections below the surface that the wheels ride upon or alongside the guideway.

The PRT system is an automated public urban transportation service with small-sized vehicles that seat one to six passengers and operate under computer control without drivers. These vehicles run on a dedicated network of guideways and transport the travellers from their originating station to the desired destination with no intermediate stops. In fact, passengers get on and off the PRT vehicles at only stations and can usually depart within few seconds after arriving at the PRT station using vehicles that await them (Mueller and Sgouridis 2011).
