This Technical Specification describes the Public Transport In formation (PTI) Application, which is intended to cover all modes of public (i.e. collective) transport as well as inter-urban and intra-urban travel. The application is designed to allow the efficient and language independent delivery of public transport information directly from service provider to end-users. The term "application" is used in TPEG specifications to de scribe specific applications, such as in this case the public transport information application, which comprises three information containers: the message management container, the application event container and the TPEG-location container. The first two containers are fully described herein and the TPEG-location container is described in CEN ISO/TS 18234-6. Each TPEG Application (e.g. TPEG-PTI) is assigned a unique number that is called the Application IDentification (AID). An AID is defined whenever a new application is developed. The AID is used within the TPEG-Service and Network Information Application (CEN ISO/TS 18234-3) to indicate how to process TPEG content and allows routing of data to an appropriate Application decoder. AID = 0002 (hex) is assigned to the TPEG-PTI application, described in this specification. The TPEG-PTI application aims at describing "legs" of a journey also described as "rides" by other methodologies. However, it is important to note that TPEG-P TI is not limited to describing single services, because it also allows the more general description of route, service and area-wide problems. Public (or collective) transport information is usually consumed in one of four principle ways as follows : Leader board information as used at stations or terminals; A report on the state of a network; The description of an individual service; As a news flash report. The elements needed to provide information for any one of the four end-user presentation modes are largely the same. The end-user focus of TPEG applications makes it useful to be able to mimic presentations, to which end-users are accustomed, for example a railway station indicator board. TPEG-PTI messages can therefore group data elements to present one of the following end-user presentation modes: Incident message report; Station/terminal information;
