The Office of Road and Rail has put out a Consultation on ‘Principles for managing level crossing safety’. See https://www.orr.gov.uk/sites/default/files/2021-01/consultation-on-principles-for-managing-level-crossing-safety-guidance.pdf
I became aware of this when checking out the reason why a stupid 'Cyclists Dismount' sign has appears at one of the Queen Adelaide level crossings. Dismounting on this narrow road that has lots of agricultural vehicle and heavy goods vehicles on it is unwise. On the other hand, the angle at which the rail track crosses the road eats up cycle front wheels regularly. But changing the nature of the hazard is not a sensible way forward.
