ABSTRACT

Driving speed is one of the most important factors in road safety, and speed not only affects the severity of a but is also related to the risk of being involved in a crash. Inappropriate speed is responsible for more than a third of all fatal accidents occurring on the roads. In Poland, the problem of speeding drivers is widely common. Hence, effective speed management and enforcement of speed limits on the existing road an important role. Possible solutions for rural roads are very limited and have focused mainly on administrative speed limitations and speed cameras enforcement. However, due to their limited effectiveness, new solutions are still being sought. High expectations are associated with the latest introduction of sectional speed system in Poland. The aim of this paper is to examine the efficiency of the sectional speed control system implemented on chosen sections of national roads in Podlaskie province. For this purpose, speed surveys included road segments where the system for sectional speed control had been already implemented, as well as in order to evaluate its effectiveness, speed measurements were conducted on other national roads with no further specific restrictions. In addition, to evaluate the possible influence of the sections monitored by the system on driver’s on adjacent segments, the relevant speed data was collected on adherent sectors. On the basis of the conducted measurements, high effectiveness of sectional speed control system was stated together with its impact on adjoining segments, but also some deficiency in terms of speed homogeneity has been revealed.
