The systems behind bus operations

Public transport networks rely on ITS, onboard bus systems, control centres and passenger information platforms to manage daily operations. From vehicle tracking to passenger information, service monitoring depends on close coordination between buses and control centres. Trapeze uses open standards to integrate these systems, making it easier to introduce new technology or change systems over time. Revised first paragraph for readability and plain English

Systems don’t easily fit together

Public transport networks rely on a mix of systems, from fleet management and passenger information to ticketing and traffic. Many were introduced over time and built by different vendors, often using proprietary technology. Integration and data sharing takes time and effort. Without open standards, this leads to:

  • Slower rollout of new technology
  • More effort to coordinate services between agencies
  • Inconsistent passenger information across the network.

Where operators, fares and data collide

Bus networks rarely run in isolation. That means journeys can involve multiple operators, different fare types and high ticket volumes across channels. While integrated ticketing makes travel easier for passengers, it makes revenue harder to manage. Authorities need to deal with complex fares, meet transparency requirements, and avoid disputes, often working with data spread across different systems. There isn’t always a clear way to bring it together.

ITS built on open standards

Trapeze gives transport authorities an ITS AVL platform built on internationally recognised open standards. Systems used in control centres, on buses and partner platforms can exchange data without complex custom integration.

Data exchange across systems

Supports standards such as SIRI, VDV, and GTFS so operational and passenger information can be shared across control centres, agencies, and external platforms.

Control centre integration

Open interfaces allow vehicle monitoring, service data, and passenger information to be shared with traffic systems, transport management platforms, and third-party applications.

Onboard system interoperability

An ITxPT-compliant onboard architecture allows passenger displays, ticketing systems, and sensors to operate together through a common network.

Flexibility over time

Open standards make it easier to introduce new technology, work with different vendors and evolve systems over time. New technology can be introduced more affordably and with less disruption.

No system works in isolation

Each system holds only part of the picture. Real visibility depends on data moving between them in real time. Open standards make that possible without custom developments or vendor lock-in.

Poor inputs lead to bad splits

In many bus networks, revenue is still calculated using incomplete or operator-reported data. That makes it hard to reflect how passengers actually travel—and harder to stand behind the results. As networks become more integrated, these gaps become more visible, increasing pressure on authorities to produce allocations that are accurate, defensible, and not open to manipulation.

Run your entire network on
one system

With Trapeze, you can run services across control centres, buses and platforms as one network.

For transport authorities

Open standards make it easier to work with different technology providers and avoid being locked into one system.

Phased upgrades allow new systems to be introduced without disrupting day-to-day operations.

For transport operators

Operational data flows between control centres, onboard systems, and external platforms without complex integration.

New systems and services can be added without reworking existing integrations or disrupting operations.

For passengers

Real-time data shared across systems improves the accuracy and reliability of passenger information.

Integration with journey planners and mobility platforms supports smoother travel across routes and modes.

Bus network integration in action

Trapeze ITS uses open standards to connect control centres, buses and partner systems.

Supports standards such as SIRI, VDV, and GTFS. Operational and passenger data can be shared reliably between systems.

Open interfaces connect control centres with traffic systems, transport platforms and third-party applications.

Onboard systems operate through a common IP-based network. Passenger displays, ticketing systems, sensors and communication devices then work together.

Vehicle location and service data can be shared between AVL and AVM platforms. Buses can then be tracked and managed in more than one system.

Supports phased migration between systems. Old and new platforms can run in parallel, reducing risk during upgrades or replacement.

Connects with journey planners, MaaS platforms, traffic systems and smart city infrastructure for coordinated, multimodal services.
