ASSESSMENT OF THE EFFECT OF PAVEMENT ROUGHNESS ON TRAFFIC SPEED
Keywords:
assessment, IRI, pavement roughness, road surface conditions, Roughometer, traffic flow, traffic safety, traffic speed, urban streetsAbstract
Traffic safety is one of the main concerns of the highway engineers of any country. The main goal of traffic safety is to reduce the frequency and severity of road accidents. The design and construction of quality roads plays an important role in improving road safety. This article assessed the effect of pavement roughness on traffic speed by conducting experiments on the streets of Tashkent. The result shows that pavement roughness, measured by the International Roughness Index (hereinafter IRI), is indirectly proportional to traffic speed.
