What is PD CEN/TS 13149-11 about?
PD CEN/TS 13149 is a 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 13149-11 specifies a publication service for data provided by the vehicle platform, enabling all on-vehicle services to share a common understanding of the operational activity of the vehicle, based on inputs taken from chassis systems such as the J1939 CAN bus.
The Vehicle Interface Service shall publish two services, namely: a Configuration Service, based on HTTP and a Provision Service, based on UDP multicast. The provision service then provides vehicle interface data as configured by the HTTP-based configuration service,
PD CEN/TS 13149-11 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 13149-11 for?
PD CEN/TS 13149-11 on vehicle platform interface service 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 13149-11?
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 13149-11 provides you with the structure to be used by a service providing data from the vehicle platform to the on-bus network, using the Fleet Management System (FMS) for source data.
The purpose of the Vehicle Interface Service (VIS) specified in PD CEN/TS 13149-11 is to provide data from the vehicle platform to service management and information applications. It provides for the secure transmission of data from potentially safety-critical vehicle components, via a one-way publication IP-based service.
Following guidelines provided in PD CEN/TS 13149-11, you will be able to achieve more efficient development of public transport components, more efficient operation and maintenance of onboard public transport equipment, high-quality intermodal passenger services based on intermodal public transport information, integration of new public transport services.
