Road signs and traffic lights at junctions and busy crossing points may be removed in order to improve road safety. The idea may seem contradictory and goes against the decades-long trend of separating and controlling traffic and pedestrians. The idea is to create anxiety, principally in the mind of the driver, so that he or she slows down and pays greater attention. Current demarcations between pavement and road will be made indistinct by removing railings and kerbs, resurfacing both in the same material, and re-laying them so that they are on the same level. Neither drivers nor pedestrians will then feel they have right of way and both, as a consequence, will behave more cautiously. When a driver reaches a junction at which there are no traffic lights he or she must take responsibility for deciding when it is safe to cross. Previously the driver relied on the traffic lights to decide his or her action and this created a dangerous state of denial of account- ability. Incredibly, the initiative is claimed to not only make the streets safer but also to reduce congestion.
