Already 1982 the Swedish Road Safety Office presented guidelines on speed reducing devices including proposed design for roads with bus traffic and other heavy vehicle traffic. However up to now a fully acceptable design of humps on streets with regularly bus traffic does not seem to be available. The effects on bus drivers’ comfort and health when driving over three different types of humps was studied in the Stockholm area, an ergo hump, a hump with level upper surface and a bus cushion. Neither of them fulfilled the requirements set by the Swedish Work Environment Authority. Also pedestrians’ and bicyclists’ behaviour and safety, when crossing the street and interactions with motor vehicle traffic was studied at the three locations. Suggestion for future research on the topic is given in the paper. (Author/publisher) This publication may be accessed by Internet users at: http://www.ictct.org/workshop.php?workshop_nr=25
