scope:

This CEN/TS defines the specific interfaces and functionality of traffic telematics (TT) services based on the use of cellular networks. Device manufacturers are enabled to develop terminal equipment compatible to services based on this CEN/TS. This will allow for interoperability of different terminal equipment and service providers which allows competition between service providers and terminal manufacturers. Furthermore it sets the scene for international availability of these services. This CEN/TS specifies - TT-specific interfaces between terminal and service centre. This especially incorporates the message sets of the application data protocols and the service-independent communication handling (including conditional access and transport protocols). - Functionality, procedures and requirements of basic terminal components as well as their interaction with the service centre. This especially comprises conditional access and security mechanisms. - Service Specifications, which are essential to ensure consistent behaviour of terminal and service centre. The services incorporated within this issue comprise: - breakdown and emergency services - interactive traffic information services - broadcast traffic information services - navigation services (route assistance, route advice, homing) - operator services - general information services - floating car data collection It is envisaged that future research and development will lead to improvements on the services listed above as well as to the creation of new services. Nevertheless this CEN/TS provides the framework for seamless integration of new features and services into the existing architecture.switches and crossings and for check rails connected to running rails (not independently fixed to to the bearers) on wood, concrete and steel bearers in ballasted track and on slab track. It applies to switches and crossings as follows:;in main lines having a radius of curvature in divergent track greater than 150 m and subject to a maximum axle load of 260 kN;;in light rail systems having a radius of curvature in divergent track greater than 80 m and subject to a maximum axle load of 130 kN. The requirements apply to fastening systems which incorporate a resilient element and are intended for use with stock rail sections in prEN 13674-1. This European Standard is not applicable to rigid fastening systems. This European Standard is for type approval of a complete fastening assembly only. Requirements for quality control are included in standards applicable to individual components.
