Public transport - Service interface for real-time information relating to public transport operations - Part 1: Context and framework

1.1   Interfaces specified by this standard
1.1.1   Business context
Real-time information may be exchanged between a number of different organizations, or between different systems belonging to the same organization. Key interfaces include the following:
-   Between public transport vehicle control centres – generally, for fleet and network management.
-   Between a control centre and an information provision system – generally, to provide operational information for presentation to the public.
-   Between information provision systems – generally, sharing information to ensure that publicly available information is complete and comprehensive.
-   Between information provision systems – and data aggregation systems that collect and integrate data from many different sources and different types of data supplier and then distribute it onwards.
-   Between information provision systems and passenger information devices such as mobile phones, web browsers, etc.
Annex B describes the business context for SIRI in more detail.
SIRI is intended for wide scale, distributed deployment by a wide variety of installations. In such circumstances it is often not practical to upgrade all the systems at the same time. SIRI therefore includes a formal versioning system that allows for the concurrent operation of different levels at the same time and a disciplined upgrade process.
In this general framework, SIRI defines a specific set of concrete functional services. The services separate the communication protocols from the message content (‘functional services’). This allows the same functional content to be exchanged using different transport mechanisms, and different patterns of exchange. Figure 1 below shows this diagrammatically.
1.1.2   SIRI communications
SIRI provides a coherent set of functional services for exchanging data for different aspects of PT operation. A common data model, based on Transmodel 5.1, is used across all services.
A communication layer defines common procedures for the requesting and exchanging of data. Within SIRI, the same general communication protocols are used for all the different concrete functional interfaces, and specify a common infrastructure for message referencing, error handling, reset behaviour and so forth. The communications layer is defined in Part 2 of the SIRI document set.
To allow the most efficient use to be made of bandwidth and processing capacity, the SIRI communications architecture supports several different patterns of interaction. SIRI supports both request/response and publish/subscribe protocols between servers, allowing applications both to pull or to push data.
The SIRI publish/subscribe pattern of interaction follows the paradigm described in the W3C candidate standard ‘Publish-Subscribe Notification for Web Services (WS-PubSub)’. SIRI uses the same separation of concerns, and a similar terminology for Publish/Subscribe concepts as is used in WS-PubSub.
For the delivery of data in response to both requests and subscriptions, SIRI supports two common patterns of message exchange as realised in existent national systems:
-   one-step ‘direct’ delivery: allowing the simple rapid delivery of data;
-   two-step ‘fetched’ delivery: allowing a more optimised use of limited resources.
1.1.3   SIRI functional services
SIRI provides specific protocols for the following functional services, defined in Part 3 of the SIRI document set:
-   Production Timetable (PT) Service: to send daily information on the operational timetable and associated vehicle running information.
-   Estimated Timetable (ET) Service: to send real-time information on timetable, including changes based on the production service and on actual running conditions.
-   Stop Timetable (ST) Service: to provide a stop-centric view of timetabled vehicle arrivals and departures at a designated stop.
-   Stop Monitoring (SM) Service: to send real-time arrival & departure information relating to a specific stop.

Javni prevoz - Vmesnik za informiranje v realnem času za potrebe delovanja javnega prevoza - 1. del: Skladnost in okvir

Posodobitev standarda CEN/TS 15531 ob upoštevanju rezultatov projektov v različnih državah, ki so uporabljale specifikacijo, in ob upoštevanju novih zahtev. Obstoječi standard so začeli razvijati v okviru CEN TC278 WG3 SG7 leta 2002 in ga objavili leta 2007. Olajšuje interoperabilnost med sistemi za obdelavo informacij o izvajalcih prevoza (avtomatski nadzorni sistemi za vozila: AVMS), da se omogoči boljše upravljanje vozil kot tudi zagotavljanje informacij za končne uporabnike v realnem času.  Glavni elementi standarda so:  - komunikacijska plast, ki določa skupne postopke za povpraševanje po podatkih in njihovo izmenjavo. Komunikacijski postopki so enaki za vse storitve in s tem predstavljajo infrastrukturo vmesnika (povezovanje sporočil, obravnavanje napak, vedenje ob ponastavitvi). Ponovna uporaba infrastrukture vmesnika za razne tehnične storitve zagotavlja stroškovno učinkovito izvajanje in razširitev vmesnika.   o Zahteva/odziv   o Objava/naročnina Naročnine določajo tip in količino podatkov za izmenjavo. -   Vmesnik med kontrolnimi centri (AVMS) s funkcijami  o zaščita povezave (v povezavi s časom ali potovanjem)   o informacije o povezavi (v povezavi s časom)   o informacije o potniku v realnem času (tabela odhodov, postanki)   o splošna sporočila (storitev obveščanja o dogodkih in informacije)   o informacije o voznem redu in topologija omrežja (načrtovana izmenjava podatkov)   o aktivnost vozila (VIS)    - Vmesnik za informacije o voznem redu med kontrolnimi centri (AVMS) in informacijskimi sistemi s funkcijami o informacije o razporedu v realnem času  o storitev referenčnih podatkov za informacije o razporedu. Nova delovna postavka bo obravnavala delo - drugih podskupin pf WG3: * SG4 podatkovni model za javni prevoz (TRANSMODEL)  * SG9 omrežje in izmenjava voznega reda (NeTEx)   -   Obrazložitev nacionalnih zrcalnih odborov; od pojava aplikacije SIRI so se znatno povečale zahteve po informacijah s strani zainteresiranih javnih organov in predvsem odjemalcev javnega potniškega prevoza.  Obstoječi nacionalni in mednarodni »standardi« (zlasti TRIDENT, RTIG in VDV-453/454), ki so bili v uporabi še pred pojavom aplikacije SIRI, so dosegli visoko raven izvajanja. Zdaj pa je prišel čas za zamenjavo starih sistemov s SIRI in CEN/TS 15531 se mora prilagoditi novim zmogljivostim. Zato je treba nujno okrepiti in izboljšati SIRI, da bo ustrezala stopnji, ki jo danes dosega upravljanje podatkov v realnem času.
