Abstract:

Traffic calming measures are nowadays extensively used throughout many countries as a tool to harmonize speeds between different types of road users. They have therefore an important role in assuring the safety of the most vulnerable users of urban spaces such as pedestrians and cyclists. Among the variety of measures and strategies that can be used speed humps are usually one of the most widely applied measures. This is due to several reasons such as the ease of construction/installation and their efficiency in reducing vehicles speeds. Several research studies have been done in many countries on this subject. Although these previous approaches give a reasonably good idea of the speed reduction according to the geometrical characteristics of the speed hump they, generally, provide less information regarding the speed profile on the approach and exit of the speed hump. This insight can be useful providing valuable information for local planning purposes. The results achieved were interesting and enabled the development of a practical design tool that can be easily used in real situations. Therefore in this context the main goal of this study is the development of a speed profile model, using a real database and hierarchical multiple linear regression techniques, which can provide easy to use and reliable information regarding the speeds on the approach and exit of isolated speed humps.
