What is PD CEN/TS 13149-7 about?
PD CEN/TS 13149 series discusses standards for road vehicle scheduling and control systems of public transport vehicles. PD CEN/TS 13149-7 specifies the general rules for an on-board data communication system between the different systems that may be used within public transport vehicles, based on the Internet Protocol (IPv4, [3] and IPv6, [4]). This includes operational support systems, passenger information systems, fare collection systems.
PD CEN/TS 13149-7 is designed for vehicles with a fixed primary structure, where networks can be installed on a permanent basis and the system configuration task consists largely of the integration, adjustment or removal of the functional end systems that produce and/or consume data.
This document describes:
- The requirements for an on-board IP network
- The overview architecture and components for an IP based on-board network
- The modular structure of the network architecture
- The Service Oriented Architecture (SOA) approach, and approach to defining services
Who is PD CEN/TS 13149-7 for?
PD CEN/TS 13149-7 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 13149-7?
Public transport (PT) vehicles have information and communications facility, 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 13149-7 provides you with the Network and System Architecture for on-board equipment. It describes basic principles of communications including a general description of the network topology, addresses schematics, basic network services, system overview, and basic module architecture.
PD CEN/TS 13149-7 provides you with the design principles adopted in the development of IP-based services. Design goals consist of enabling communications, interoperability, quality of monitoring, maintainability, and migration of on-board systems.
PD CEN/TS 13149-7 describes the on-board IP network and the technical mechanisms to be used to connect modules to it. It covers IP addressing, name registration and resolution, communication protocols and communication methods.
