Public Transport Information and Priority System

Last updated

The Public Transport Information and Priority System, abbreviated PTIPS, is a computer-based system used in New South Wales, Australia, that brings together information about public transport entities, such as buses. Where applicable, PTIPS can also provide transport vehicles with priority at traffic signals.

Contents

PTIPS consists of a number of hardware and software components installed on-board buses which wirelessly communicate with a central set of servers. PTIPS also relies on an interface with Sydney Coordinated Adaptive Traffic System (SCATS) - to provide the priority feature) and bus/route/timetable data provided by bus organisations and government authorities.

PTIPS provides:

How PTIPS works

PTIPS works by combining, on the one hand, schedule and route path information for buses performing timetabled services (as opposed to, say, charter trips), and on the other hand, live location data transmitted by the buses to PTIPS.

PTIPS receives XML data files from the bus operators, which contain information relating to planned trips (for example, route paths, trips & schedules, bus stops etc.)

Each bus that PTIPS tracks is equipped with a hardware device that records its location via GPS, and transmits it to the central PTIPS servers via the cellular radio communications network. Buses transmit these messages at certain intervals (which are configurable, and which vary depending on what the bus is doing), and also when they pass certain points along their intended route. Apart from GPS location, the transmitted messages also include information about the vehicle and which trip it is doing.

With the above information, PTIPS can compare the location of a bus performing a certain trip, at a certain point in time, with where it should be, based on the planned route and timetable data.

Real time apps

Transport for NSW worked with several developers in late 2012 to create, and release smartphone applications with access to the real-time bus data provided from PTIPS. Released in December, several iOS and Android apps went live on their respective App stores, allowing customers to track where their buses were in real-time, as well as any delays or timetable changes as they occur. It was initially trialled on Sydney Buses' route 400. [1] [2]

In 2013, this real-time data was further expanded to provide live information from Sydney Trains, and private bus operators Hillsbus and Busways Blacktown, and was eventually rolled out across bus operators in Greater Sydney.

In 2020, Transport for NSW started working with bus operators to introduce real-time tracking to regional bus services. [3] As of March 2022, PTIPS-assisted real-time tracking was available for the regional centres of Albury, Armidale, Bathurst, Bega, Coffs Harbour, Dubbo, Forbes, Grafton, Nowra, Parkes, Port Macquarie, Queanbeyan, Tamworth, Tweed Heads and Wagga Wagga.

CountryLink was a passenger rail and road service brand that operated in regional areas of New South Wales, and to and from Canberra, Brisbane and Melbourne. Originally created as a business unit of the State Rail Authority of New South Wales, it later became a subsidiary of RailCorp. CountryLink operated rail services using XPT and Xplorer rolling stock, with connecting coach services operated under contract by private operators.

Traffic signal preemption is a system that allows an operator to override the normal operation of traffic lights. The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety. Signal preemption can also be used on tram, light-rail and bus rapid transit systems, to allow public transportation priority access through intersections, and by railroad systems at crossings to prevent collisions.

The Sydney Coordinated Adaptive Traffic System, abbreviated SCATS, is an intelligent transportation system that manages the dynamic timing of signal phases at traffic signals, meaning that it tries to find the best phasing for a traffic situation. SCATS is based on the automatic plan selection from a library in response to the data derived from loop detectors or other road traffic sensors.

NightRide is a network of bus routes in operation between midnight and 4.30am in Sydney, Australia. The sixteen routes are run by bus operators as listed below and allow for a nightly shutdown of the Sydney Trains commuter rail network. The NightRide network was established in mid-1989 as low-patronage late-night train services were progressively withdrawn. Services follow major roads, and some stops are some distance from the railway stations they replace. In addition, some routes serve stations on multiple railway lines. In the city, most services depart from George Street, above Town Hall station.

Albury Airport is a regional airport located 2 nautical miles northeast of Albury, New South Wales, Australia. The airport, which also serves Albury's adjacent twin city of Wodonga, Victoria, was the fifth busiest in New South Wales as of 2016–17, handling 257,769 passengers. However, like most Australian airports, the impacts of travel restrictions and state border closures in response to the COVID-19 pandemic resulted in a significant reduction in revenue passengers. ABX handled 107,934 passengers in the 2021–22 financial year and was the 32nd busiest airport in Australia. In addition to regular public transport flights, Albury airport handles a relatively large number of charter, freight, agricultural, and general aviation aircraft movements and hosts the official weather station for Albury–Wodonga.

A passenger information system, or passenger information display system, is an automated system for supplying users of public transport with information about the nature and the state of a public transport service through visual, voice or other media. It is also known as a customer information system or an operational information system. Among the information provided by such systems, a distinction can be drawn between:

<span class="mw-page-title-main">Journey planner</span>

A journey planner, trip planner, or route planner is a specialized search engine used to find an optimal means of travelling between two or more given locations, sometimes using more than one transport mode. Searches may be optimized on different criteria, for example fastest, shortest, fewest changes, cheapest. They may be constrained, for example, to leave or arrive at a certain time, to avoid certain waypoints, etc. A single journey may use a sequence of several modes of transport, meaning the system may know about public transport services as well as transport networks for private transportation. Trip planning or journey planning is sometimes distinguished from route planning, which is typically thought of as using private modes of transportation such as cycling, driving, or walking, normally using a single mode at a time. Trip or journey planning, in contrast, would make use of at least one public transport mode which operates according to published schedules; given that public transport services only depart at specific times, an algorithm must therefore not only find a path to a destination, but seek to optimize it so as to minimize the waiting time incurred for each leg. In European Standards such as Transmodel, trip planning is used specifically to describe the planning of a route for a passenger, to avoid confusion with the completely separate process of planning the operational journeys to be made by public transport vehicles on which such trips are made.

The Sydney–Melbourne rail corridor is an approximately 953-kilometre (592 mi) standard gauge railway corridor that runs between Melbourne (Victoria) and Sydney, the two largest cities in Australia. Freight and passenger services operate along the route, such as the NSW TrainLink XPT passenger service. The XPT offers a day and night service in each direction.

BRIDJ is a SaaS platform designed to support ‘demand responsive’ or ‘on demand’ public transport providers. The platform allows a user to optimise an on-road service and digitise work processes, and includes an optimisation engine, traveller app, driver app and client portal. The traveller app allows passengers to book, pay and track a service between two locations within a service area. The optimisation engine consumes pre-planned and real-time bookings and then allocates passengers to the available vehicles to create the optimal trips for the given service objectives. The optimisation engine is designed to handle large numbers of passengers and vehicles of both small capacities and high capacity (6-50+). BRIDJ technology is currently deployed on public transport services in both Sydney and Adelaide, Australia and for transfer services Singapore.
