The suitability and effectiveness of humps for alerting drivers and controlling vehicle speeds have been investigated. Seven vehicles including private cars, goods vehicles, a moped and a bus were used in the tests and six subjects made estimates of the noticeability and discomfort of the different humps at various crossing speeds. Two main classes of hump have been studied, short humps which could be straddled by the wheels of most vehicles and long humps which could be straddled only by some large vehicles. The humps ranged from 2 in to 12 ft in length and from 0.5 in to 6 in in height. (Modified author abstract)
