What is ISO/TR 21724-1 about?
ISO/TR 21724 is a series of intelligent transport systems focuses on Common Transport Service Account (CTSA) concept. ISO/TR 21724-1 describes the characteristics of a Common Transport Service Account System (CTSA). It presents the common transport service account framework and associated use cases.
The CTSA role model covers relevant transport services, the payment methods, the account types where the user of the service is charged for the service and that requires a more overall role and responsibilities model.
The model also defines external stakeholders that impact and border the model, that is, the general financial (banking) system. The framework assumes an account-based system where charges for services are calculated and charged in the account system.
Who is ISO/TR 21724-1 for?
ISO/TR 21724-1 on common transport service account systems is useful for:
- Public transport authorities
- Toll authorities
- Public and private parking providers
- Transportation industries
Why should you use ISO/TR 21724-1?
Many transportation services (public transport, tolled roads, parking, city bike rental etc.) require payment systems.. Automated fare collection has progressed from use of magnetic technology to contactless smart cards, and recently to open financial payments and mobile payment applications. ISO/TR 21724-1 covers convergence of toll fee collection and payment and public transport fare collection and payment through the integration of the systems’ accounts rather than their fee/fare payment media.
ISO/TR 21724-1 examines the concept, functional requirements, and benefits of converging payment systems for tolling, public transport and other transport services through a central account linkage.
ISO/TR 21724-1 presents the Common Transport Services Account System framework and architecture including the definition, requirements, role model and role descriptions, modes, and flows of the system. This CTSA framework described in ISO/TR 21724 assumes a technology-agnostic front end with respect to the payment media and reading equipment. The focus of this framework is the back-office/account management system as a vehicle to integrate multiple transport services and managers.
The main idea behind the CTSA framework is to provide a transport service user with the benefit of seamless acquisition of access rights to multiple transport services by multiple service/operator managers through a common transport account.
