Personal public transport (PPT) is a network of private rental vehicles for users to drive, distributed at fixed locations throughout an area and available to the general public in such a way that each user has the ability to determine the route and schedule on a self-service basis (without advance prebooking). The design of a PPT system encourages utility (usually trips) over revenue.
While most public transport systems operate on specific routes with set timetables, PPT systems utilize a network of vehicles at various locations for users when they desire them, allowing those users to take any route that serves their needs and to return the vehicle to any designated point within the coverage area. The user operates or directs, in an auto-drive vehicle, the vehicle to the destination versus this being done by a driver or conductor in traditional public transport options. Similar to traditional public transport options, the system is managed by a transit authority or private transport operator but the pricing model encourages users to return the vehicle quickly. Maximizing vehicle utility over revenue means operators seek revenue from other sources such as advertising, subsidy and system sponsorship.
Personal public transport was conceptualized to explain the unique difference in service provided over traditional public transport options such as bus, rail, taxi and rapid transit as well as paratransit and personal rapid transport.
Instead of utilizing routes, in the way that traditional public transport does, a PPT system operates within a defined area, termed the coverage area. Vehicles can be found or left anywhere the law allows within that area or at specific locations within the coverage area. Examples of specific locations can be public or private demarcated areas shared with other vehicles or specific station locations.
The vehicle is designed to cater to an individual user or a small party's transport needs (not shared with strangers for the rental duration like public transport). The vehicles are intended for a single trip on public thoroughfares either shared by other modes or segregated. The user is responsible for adhering to all laws and regulations while using the vehicle and enforcement is done through existing public law enforcement mechanisms such as licensing and ticketing.
While a PPT is a general public transport service not requiring advance prebooking, it generally requires users to be registered with the system or to pay a deposit to ensure the return of the vehicle in good working condition. The tipping point of successful PPT systems has been the application of information technology systems (ITS) enabling user identification and vehicle tracking in a system. This is usually aided by Radio Frequency Identification Devices (RFID) and real-time information flow using wireless internet. GPS tracking devices are also common in vehicles to guard against theft.
PPT is financed through a variety of mechanisms similar to other public transportation projects. Capital costs are usually covered through government subsidy (exceptions do exist) and there are multiple revenue streams which strive to cover operating costs. Revenue streams vary greatly depending on the system and attributes and laws of the area it is implemented. Many times government subsidies are needed to meet the operating costs. The pricing model of PPT encourages short trips and multiple uses over revenue. This pricing model prioritizes utility at the expense of revenue and is a key differentiating factor between PPT and private vehicle hire and some other modes of public transport.
Many bicycle sharing programs globally are examples of PPT. [1] [2] Large citywide bicycle sharing programs such as Velib, Capital Bikeshare, and BIXI Montréal all have attributes of PPT. Bicycle rental enterprises are not PPTs because the bicycles have to be used and returned to a single location and the pricing model encourages users to keep the bicycles out for greater lengths of time.
A few medium to large cities have a system of Motorized scooters for individuals to ride short to medium distances.
Some car sharing systems are also examples of PPT.
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip may require the bundling of services provided by several firms, agencies and modes.
A toll road, also known as a turnpike or tollway, is a public or private road for which a fee is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance.
Parking is the act of stopping and disengaging a vehicle and usually leaving it unoccupied. Parking on one or both sides of a road is often permitted, though sometimes with restrictions. Some buildings have parking facilities for use of the buildings' users. Countries and local governments have rules for design and use of parking spaces.
Private transport is the personal or individual use of transportation which are not available for use by the general public, where in theory the user can decide freely on the time and route of transit, using vehicles such as: private car, company car, bicycle, dicycle, self-balancing scooter, motorcycle, scooter, aircraft, boat, snowmobile, carriage, horse, etc., or recreational equipment such as roller skates, inline skates, sailboat, sailplane, skateboard etc.
Utility cycling encompasses any cycling done simply as a means of transport rather than as a sport or leisure activity. It is the original and most common type of cycling in the world. Cycling mobility is one of the various types of private transport and a major part of individual mobility.
A bicycle-sharing system, bike share program, public bicycle scheme, or public bike share (PBS) scheme, is a shared transport service where bicycles are available for shared use by individuals at low cost.
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions. It usually includes issues surrounding policy and regulation, service provision and standardization.
Carsharing or car sharing or car clubs (UK) is a model of car rental where people rent cars for short periods of time, often by the hour. It differs from traditional car rental in that the owners of the cars are often private individuals themselves, and the car sharing facilitator is generally distinct from the car owner. Car sharing is part of a larger trend of shared mobility.
Intermodal passenger transport, also called mixed-mode commuting, involves using two or more modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths of various transportation options. A major goal of modern intermodal passenger transport is to reduce dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey.
In the context of European Union law, a public service obligation or PSO is an obligation imposed on an organisation by legislation or contract to provide a service of general interest within EU territories. PSOs may operate in any field of public service, but postal services, social services, energy, transport and banking are specific sectors where the concept is relevant.
A car rental, hire car or car hire agency is a company that rents automobiles for short periods of time to the public, generally ranging from a few hours to a few weeks. It is often organized with numerous local branches, and primarily located near airports or busy city areas and often complemented by a website allowing online reservations.
Vélib' Métropole is a large-scale public bicycle sharing system in Paris, France. The system encompasses more than 16,000 bikes and 1,400 stations. The name Vélib' is a portmanteau of the French words vélo ("bicycle") and liberté ("freedom").
Shared transport or shared mobility is a transportation system where travelers share a vehicle either simultaneously as a group or over time as personal rental, and in the process share the cost of the journey, thus purportedly creating a hybrid between private vehicle use and mass or public transport. It is a transportation strategy that allows users to access transportation services on an as-needed basis. Shared mobility is an umbrella term that encompasses a variety of transportation modes including carsharing, Bicycle-sharing systems, ridesharing companies, carpools, and microtransit.
Public transport is a system of transport for passengers by group travel systems available for use by the general public unlike private transport, typically managed on a schedule, operated on established routes, and that may charge a posted fee for each trip. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses, trolleybuses, trams and passenger trains, rapid transit and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world.
Santander Cycles is a public bicycle hire scheme in London in the United Kingdom. The scheme's bicycles are popularly and colloquially known as Boris Bikes, after Boris Johnson who was Mayor of London when the scheme began operating.
Capital Bikeshare is a bicycle-sharing system which serves Washington, D.C., and certain counties of the larger metropolitan area. As of January 2023, it had 700+ stations and more than 5,400 bicycles. The member jurisdictions own most of the equipment and have sourced operations to contractor Motivate International. Opened in September 2010, the system was the largest bike sharing service in the United States until New York City's Citi Bike began operations in May 2013.
Yourdrive was a New Zealand peer-to-peer carsharing company. Prior to ceasing operations it facilitated a system in which individuals could rent their privately owned vehicles on an hourly, daily or weekly basis to other registered users of the service. Owners set their rental prices and earn a 60 percent commission from the rental revenue. Prior to going out of business it operated throughout New Zealand with vehicles in Auckland, Hamilton, Palmerston North, Wellington, Christchurch, Queenstown and Dunedin.
Mobility as a service (MaaS) is a type of service that, through a joint digital channel, enables users to plan, book, and pay for multiple types of mobility services. The concept describes a shift away from personally-owned modes of transportation and towards mobility provided as a service. This is enabled by combining transportation services from public and private transportation providers through a unified gateway that creates and manages the trip, which users can pay for with a single account. Users can pay per trip or a monthly fee for a limited distance. The key concept behind MaaS is to offer travelers mobility solutions based on their travel needs.
Cycling in Penang Island refers to the use of bicycles in the city of George Town and elsewhere on Penang Island, Malaysia, either for recreational, touring or transportation purposes. While bicycles have long been in use in Penang, with rickshaws becoming a unique application of the pedal-driven vehicle in the state, the usage of bicycles has noticeably declined since the late 20th century due to the proliferation of cars as the main transportation mode.
Micromobility refers to a range of small, lightweight vehicles, driven by users personally. Micromobility devices include bicycles, e-bikes, electric scooters, electric skateboards, shared bicycle fleets, and electric pedal assisted (pedelec) bicycles.
