What is PD CEN/TS 13149-9 about?
PD CEN/TS 13149 series of products concerns on-board data communication systems on public transport vehicles. This series provides for data services that enable open and managed to share of relevant information.
PD CEN/TS 13149-9 specifies a time publication, enabling all on-vehicle services to share a common understanding of current time, based on a suitable agreed master network clock.
PD CEN/TS 13149-9 covers:
- The functional scope, i.e., which data the service provides, why, when and how often
- The transport protocol, i.e., how the data are transmitted
- The service publication, i.e., how the service can be found by other modules or applications
- The structure of the data, i.e., how the data are structured and how the data elements are named
Who is PD CEN/TS 13149-9 for?
PD CEN/TS 13149-9 on road vehicle scheduling and control systems is useful for:
- Public transport operators
- Public transport service providers
- Organizations involved in public transport operations
- Transport information systems
- Network engineers
Why should you use PD CEN/TS 13149-9?
Public transport (PT) vehicles have information and communications facilities, including ticket machines, Automated Vehicle Location (AVL) systems, destination displays, passenger announcement systems, vehicle monitoring systems to enable voice and data to be exchanged with the control center, other PT vehicles, PT infrastructure and roadside devices.
PD CEN/TS 13149-9 provides you with the structure to be used by a time service providing time data to the on-bus network.
PD CEN/TS 13149-9 provides you with the functional scope of time service which enhances mechanisms for the synchronization of server clients based on a server time. For time synchronization the Simple Network Time Protocol (SNTP) shall be used.
Following guidelines provided in PD CEN/TS 13149-9, you will be able to develop efficient public transport components, Also, you will be able to seamlessly maintain the onboard public transport equipment. Additionally, you can achieve high-quality intermodal passenger services based on intermodal public transport information, and integration of new public transport services.
