Post-construction surveys conclusions on the use of speed tables in traffic calming

Abstract

One of the key issues in managing street traffic of vehicles is traffic calming in built-up areas. It consists in introducing 30 km/h zones or home zones in exclusively residential areas. In Poland, the most frequently applied measures are vertical traffic calming measures due to lower construction costs and occupancy area compared to horizontal traffic calming measures. Available literature proposes different models of determining speed after the speed table (ST) or speed reduction a given ST element can trigger. In most cases, however, these are results of studies conducted in transport research laboratories or in driving simulators. This article presents results of vehicle speed measurements conducted in three example – specially selected – study areas with diverse impact factors that traffic calming designers should take into account in ST designs. Based on the vehicle speed measurements carried out, it has been demonstrated that not only does the height of ST, but also other factors such as: horizontal and vertical deflections, street function, number of exits to properties and side roads, street landscaping surroundings and geometrical parameters of STs. The above findings may become helpful with the planned road investments, in order for STs to be efficient and favour the creation of safe urban environment for all users.
