Intelligent transport systems - eSafety - Part 3: eCall for Coaches and buses

In respect of 112-eCall (operating requirements defined in EN 16072), this document defines additional specifications for the provision of eCall for coaches and buses.
As with the existing provisions for eCall for Category M1/N1 vehicles, these are specified within the paradigm of being OEM fit equipment supplied with new vehicles.
NOTE 1   The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of other work, and in respect of the operational requirements for any such aftermarket solutions for coaches and buses, will use the specifications of this document as a reference point.
NOTE 2   The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third party service provision by comparison, involves the support of an intermediary third party service provider before the call is forwarded to the PSAP.) The specifications herein relate only to the provision of 112-eCall or IMS-112-eCall, and do not provide specifications for third party service provision of eCall, although in the case of 112-eCall or IMS-112-eCall for coaches, links to third party provision of service aspects (such as passenger lists) may be required.

Intelligente Verkehrssysteme - ESicherheit - Teil 3: ECall für Reisebusse und Busse

Im Hinblick auf 112-eCall (betriebliche Anforderungen entsprechend EN 16072) legt diese Zielvorgabe Europäischer Normen zusätzliche Spezifikationen für die Bereitstellung von eCall für Reise- und Stadtbusse fest.
Wie bei den bereits bestehenden Bestimmungen zu eCall für Fahrzeuge der Kategorie M1/N1 werden diese innerhalb des Paradigmas spezifiziert, dass es sich um eine Ausrüstung handelt, die vom Originalgerätehersteller in Neufahrzeuge eingebaut wird.
ANMERKUNG 1   Die Bereitstellung von eCall für Fahrzeuge über den Nachrüstmarkt (nach Verkauf und Zulassung) wird den Gegenstand einer anderen Arbeit bilden, die im Hinblick auf die betrieblichen Anforderungen für derartige Nachrüstlösungen für Reise- und Stadtbusse diese Technische Spezifikation als Anhaltspunkt verwenden wird.
ANMERKUNG 2   Das 112-eCall-Paradigma beinhaltet einen Direktanruf vom Fahrzeug bei der zuständigen Notrufzentrale (en: Public Safety Answering Point, PSAP). (Zum Vergleich: Die Diensterbringung durch Dritte beinhaltet die Unterstützung eines zwischengeschalteten externen Dienstleisters, bevor der Anruf an die PSAP weitergeleitet wird.) Die hierin enthaltenen Spezifikationen beziehen sich nur auf die Bereitstellung von 112-eCall oder IMS-112-eCall und bieten keine Spezifikationen für die Erbringung von eCall-Dienstleistungen durch Dritte, obwohl im Fall von 112-eCall oder IMS-112-eCallfür Reisebusse die Verknüpfung mit der Bereitstellung von Dienstleistungsaspekten (wie z. B. Passagierlisten) durch Dritte erforderlich sein kann.

Inteligentni transportni sistemi - e-Varnost - 3. del: e-Klic za medkrajevne in mestne avtobuse

V zvezi s storitvijo e-Klic 112 (zahteve za delovanje so določene v standardu EN 16072) ta dokument določa dodatne specifikacije za zagotavljanje e-Klica za potniške vagone in avtobuse.
Tako kot obstoječe določbe za e-Klic za vozila kategorije M1/N1 so tudi te določbe opredeljene v okviru paradigme, da gre za originalno nameščeno opremo (OEM), ki je dobavljena z novimi vozili.
OPOMBA 1: Zagotavljanje e-Klica za vozila po naknadni vgradnji (po prodaji in registraciji) bo predmet drugih dokumentov. V okviru zahtev za delovanje za katere koli take naknadne rešitve za potniške vagone in avtobuse bodo specifikacije tega dokumenta uporabljene kot glavna referenčna točka.
OPOMBA 2: Primer e-Klica 112 je neposredni klic iz vozila do najustreznejšega centra za usklajevanje reševanja. (Zagotavljanje storitev tretjih ponudnikov – za primerjavo – vključuje podporo posredniškega tretjega ponudnika storitev, preden je klic posredovan centru za usklajevanje reševanja.) V tem dokumentu navedene specifikacije se nanašajo samo na zagotavljanje e-Klica 112 ali e-Klica 112 IMS in ne zagotavljajo specifikacij za zagotavljanje storitve e-Klic tretjega ponudnika, čeprav bodo v primeru e-Klica 112 ali e-Klica 112 IMS za potniške vagone morda potrebne povezave do zagotavljanja storitev (npr. seznami potnikov) tretjih ponudnikov.

Introduction

As a result of European Regulation, from 2018, all new model Category M1/N1 vehicles will be equipped

with112- eCall. Other model Category M1/N1 vehicles may be voluntarily equipped with 112-eCall.

The current eCall Regulation covers only M1 and N1 Category vehicles (cars and vans). The European

Commission’s “ICT Rolling Plan (2017) states the objective “Action 1 Develop technical

specification/standards for the implementation of eCall in vehicles of categories other than M1 and N1 and

for other user types, taking into account requirements included within type approval regulation as well as

ongoing activities in this area (pilots, CEF,…).” And goes on to explain “…for the extension to other vehicles

types and services, such as Heavy Duty Vehicles, Power Two Wheelers or Hazardous Goods tracking, and

other classes of vulnerable road users”.
See CEN/TR 17249-1 for context.

The EC CEF project I_HeERO has also addressed the issues relating to eCall for HGVs, coaches and buses

and vehicle centric solutions for powered two wheel vehicles (P2W) and have passed these results to

CEN/TC 278 PT1507 who are charged to provide specifications for the provision of eCall for Heavy Goods

Vehicles, coaches and buses, agricultural tractors, and powered two-wheel vehicles.

Coaches and buses present two different challenges for eCall, and, despite the fact that the same vehicle

model could be used either as a coach or a bus, require different information. In the case of long distance

coaches, European regulations require that passengers use seat belts, so it is possible to establish the

number of seats in use, which will approximate to the number of passengers on board. Coach trips are

usually booked in advance, and the coach operator therefore also has a passenger list with information

that could be very valuable to the emergency responders, especially for coaches operating abroad, but

must respect privacy regulations. Bus trips, by comparison, involve semi-random unplanned Hop-on/hop-

off characteristics, with little or no use of seat belts.

This document provides determination for the provision of eCall to coaches and buses. As with the existing

provisions for eCall for Category M1/N1 vehicles, these are specified within the paradigm of being OEM

fit equipment supplied with new vehicles.

The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of

other work, and in respect of the operational requirements for any such aftermarket solutions for coaches

and buses, will use the specifications of this document as a principle reference point.

1 Scope

In respect of 112-eCall (operating requirements defined in EN 16072), this document defines additional

specifications for the provision of eCall for coaches and buses.

As with the existing provisions for eCall for Category M1/N1 vehicles, these are specified within the

paradigm of being OEM fit equipment supplied with new vehicles.

NOTE 1 The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of

other work, and in respect of the operational requirements for any such aftermarket solutions for coaches and buses,

will use the specifications of this document as a reference point.

NOTE 2 The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third party

service provision by comparison, involves the support of an intermediary third party service provider before the

call is forwarded to the PSAP.) The specifications herein relate only to the provision of 112-eCall or IMS-112-eCall,

and do not provide specifications for third party service provision of eCall, although in the case of 112-eCall or IMS-

112-eCall for coaches, links to third party provision of service aspects (such as passenger lists) may be required.

6 General overview of the eCall session for 112-European eCall for coaches and
buses
6.1 Context

This document is based on the definition of an eCall session as defined in EN 16072, providing data as

determined in EN 15722.

This document provides specifications to extend the scope of eCall to benefit incidents involving UNECE

Category M vehicles, and is determined within the general context of the paradigm of eCall for coaches

and buses described in CEN/TR 17249-1:2018 in its general provisions, and particularly in Clause 11,

which is specific to coaches and buses.

This specification provides parameters and protocols to enable the provision of eCall to coaches and buses

6.2 Categories of vehicles

See CEN/TR 17249-1:2018, 6.3 for greater detail and sub-classifications and Clause 11 of that document

for coach and bus specific considerations of vehicle type data and accident related data.

This specification is directed at two principle categories of coaches and buses:

– Category M2 Vehicles used for the carriage of passengers, comprising more than eight seats in

addition to the driver's seat, and having a maximum mass not exceeding 5 t.

NOTE 1 This category of vehicles is more commonly described as “small coach” or “people carrier”, but also

described as “bus” in some use cases.

– Category M3 Vehicles used for the carriage of passengers, comprising more than eight seats in

addition to the driver's seat, and having a maximum mass exceeding 5 t.

NOTE 2 This category of vehicles is more commonly described as “large coach”, but also described as “bus”

in some use cases.

The basic requirement of eCall for coaches and buses in the event of an incident, is the transmission of an

MSD (as specified in EN 15722), to the most appropriate PSAP and the opening of a voice channel between

that PSAP and the occupants of the vehicle remain – basically - the same for coaches and buses as for

private vehicles, however, there are some differences:

a) there may be additional information that would be of use to the PSAP in assessing the situation

(see Clauses 7 and 8 below);
b) the PSAP may or may not wish to talk to the passengers as well as the driver.

NOTE 3 Coach designers may wish to provide a facility for the PSAP to speak to passengers via the vehicles PA

system. But this is considered, at this stage, to be a feature of OEM design and not a requirement.

7 General Requirements
7.1 Automatic or manual

An eCall from a Category M2 or Category M3 vehicle may be automatically or manually triggered as

specified in EN 16072.
7.2 Triggering conditions

The conditions for triggering of eCall, as described in EN 16072:2015, 7.10, shall also apply to eCall for

coaches and buses UNECE Category M.
---------------------- Page: 12 ----------------------
SIST-TS CEN/TS 17249-3:2019
CEN/TS 17249-3:2018 (E)

Instigation of triggering and the technical means of triggering, in this OEM provided paradigm, shall be

determined by the designer of the system, however such provisions shall trigger an eCall in the event of:

• Significant collision;
• Fire;
• Rollover;
• Other conditions considered appropriate by the system designer;
• Manual instigation.

“Significant collision” in this paradigm are the conditions that the system designer determines should

generate an eCall.
7.3 Specification of the use case OAD

See CEN/TR 17249-1:2018, Clause 11 for explanation of the process followed in reaching this

specification.

All data included in the minimum set of data defined in EN 15722 are valid and necessary for M category

vehicles.

Additional data, if available, may assist the PSAP to determine what type and number of rescue resources

are sent to the scene of the incident, and, if available, may provide more information about the type and

condition of the vehicle, and consequences of the accident to passengers and the driver. The ‘Optional

Additional Data‘ concept (OAD) titled ‘Coach and bus 1’ and named CB1 for brevity serves this purpose.

Some data needs to be stored or calculated by the equipment installed inside the vehicle. In the case of a

coach or bus this implies more data than the standardized predefined fields specified in EN 15722. These

additional fields therefore need to be defined and provided in an optional additional data field presented

within the MSD, and are specified below.

The operator may provide a contact number where the PSAP may obtain further information regarding

the vehicle and in some cases, passenger lists, etc.
Classification and contents of data elements are given in the following clauses.
7.4 Data requirements
7.4.1 MSD Data Requirements

Data defined in EN 15722 MSD core data requirements shall be reported in accordance with EN 15722.

Table 1 provides a summary of the semantic contents of the MSD, for a full description please refer to

EN 15722.
