Evaluation of Traffic Measurements for Speed Reduction

Abstract

This paper evaluates the effect of road humps to reduce through traffic and motor-vehicle speeds in residential streets. An experimental scheme to install 22 humps was carried out in Nitshin area in Saga city. These road humps were not useful to reduce through traffic but achieved slower speeds. School children and inhabitants in this area felt that the traffic condition on these reads was safer and agreed with existing of these humps. As a result, 14 humps were removed because of the opposite of people living these streets.
