It works on a sensor and an infra red emtting signal device in the vehicles that have access to that road/path. If your car has one in it and you apparoach the barrier then it will lower. Other systems have a simple key pad to punch in an access code to drop the bollards

It's a common thing in the UK, they're automatic. Only buses and taxis get through, once they pass the barrier raises back up. Easy enough for motorcyclists like myself to go round but for car drivers... well just watch the gif again.
