Not to my knowledge, this probably refers to the sections of centre running track, where there is only a single lane, where emergency vehicles are supposed to be able to use the track in order to avoid traffic in the single through lane. Of course these sections already have barrier curbs, and despite what some claim, emergency vehicles can mount barrier curbs, there is no reason to use roll curbs for this purpose.
