The proposed text combines the proposed changes in GRVA/2020/8 (proposal for a maximum time of 15 seconds for a lane change) with the adopted changes in GRVA/2019/24.

Proposal combining the proposed changes of GRVA/2020/9 with the previously adopted changes in GRVA/2019/24.

Amendments to refine the proposal to increase maximum lateral acceleration limit values up to 4 m/s² for speeds up to 80 km/h for M1/[N1] category vehicles, provided there is no heavy rain and ambient air temperatures are above 4°C. The proposal sets the speed at 60 kph while specifying a linear reduction of lateral acceleration to a maximum 3 m/s² at 80 kph.

Proposal to clarify conditions for automatic deactivation of the direction indicator pursuant to a lane change maneuver.

This proposal intends to allow the system to have a grace time in order to deal with unexpected changes in the radius of the curvature of the bend, by allowing the system to exceed the imposed ayxsmax limit of 3 m/s² by a maximum of 40% for up to 2 seconds.

This proposal revises the changes proposed in document GRVA/2020/7 based on stakeholder feedback. The proposal introduces provisions for M₁ vehicle to allow for lateral accelerations up to 40% greater than the 3 m/s² limitation for a period up to two seconds in order to in order navigate unexpected changes in the radius of the curvature of a bend and avoid driving behaviour that may be unexpected and/or confusing to the operator and following vehicles.

Proposal for amendments to document GRVA/2020/22.

Proposal to allow a grace time in order to deal with unexpected changes in the radius of the curvature of a bend by permitting the system to exceed the ay_smax limit of 3 m/s² by a maximum of 40 per cent for up to two seconds.

Proposal to allow up to seven seconds to start and perform a lane change.
