Editorial corrections to document WP.29/2015/88 proposing to introduce fire suppression systems for buses and coaches upon detection of fire in the engine and/or heater compartment.

Discussion of the state of accident statistics and other data to support the development of coach and bus safety requirements.

Proposal to correct that apparent omission of paragraph 7.5.1.5 in Annex 3 in the formal proposal to introduce mandatory fire suppression systems in certain buses and coaches (document GRSG/2015/32).

Proposal to clarify provisions concerning the deactivation of emergency door controls to prevent doors from being opened while the vehicle is in motion. The proposal specifies the focus on interior controls and would reduce the speed threshold for deactivation from 5 km/h to 3 km/h based on reports from bus operators.

UN R107 includes a provision to prevent a folding seat used by the crew from obstructing the view of the exterior rear-view mirror. GRSG approved the Netherlands proposal (document GRSG/2015/14) to apply this restriction to rear-view camera monitors. Germany submits, however, that because the positioning of monitors inside the vehicle differs from that of exterior mirrors, direct application of these requirements may result in positioning below the line of sight and therefore proposes to clarify the requirement to ensure safe installation of rear-view monitors and mirrors.

UN R107 includes a provision to prevent a folding seat used by the crew from obstructing the view of the exterior rear-view mirror. In light of the proposed amendment to introduce camera-monitor systems into UN R46 (indirect vision), this proposal would extend the same treatment to CMS used in the place of rear view mirrors.

Proposal to clarify the requirements concerning the height of steps in vehicles which comply with Annex 8.

Proposal to redefine the measurement criteria for determining appropriate seat spacing in order to address observed cases where adequate spacing is not achieved even though the current criteria are fulfilled. The type approval authorities of the member states of the European Union (TAAM) discussed the proper interpretation of the text of the Regulation in the case of seats with a central recess (sunken area) and decided that the text of the Regulation needed to be modified in order to provide an adequate method to measure the H dimension.

The aim of this corrigendum is to correct the text of the Regulation and to restrict the mandatory application of the requirements on dedicated areas for prams and pushchairs to Class I vehicles.

Proposal to mandate fire suppression systems on vehicles of Classes I and II as a new 07 series of amendments to UN R107. It is mainly based on ECE/TRANS/WP.29/GRSG/2014/6/Rev.1, amended as reproduced in GRSG-108-51, submitted to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft Supplement 4 to the 06 series of amendments to Regulation No. 107 (ECE/TRANS/WP.29/2015/88).

Pursuant to the proposal to enable the use of autonomous compressed natural gas (CNG) heaters for the purpose of heating the engine coolant under UN R110, this proposal would require that the alarm system and fire suppression system (required through paragraph 7.5.1.5. as amended by Supplement 4 to 06 series of amendments) be activated as soon as the heater is in function and even if the engine is not operational.

Incident reports confirm that occupants of exposed seats have been thrown forward during heavy braking or vehicle impact conditions, often sustaining head injuries from contact with the vehicle floor or other hard structure. Seats particularly affected are those located immediately to the rear of an open wheelchair or buggy space. This proposal aims to reduce this risk by extending existing requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward.

Proposal to introduce mandatory requirements for fire suppression systems for Class III buses and coaches (and optional requirements for other classes) activated upon detection of fire in the engine and/or heater compartment. This proposal also extends the treatment of rear-view mirrors to any camera-monitor systems used in place of rear-view mirrors.
