Relationship Among Traffic Intensity, Intersection Geometry, And Users' Behavior

Abstract

Even though the parts of a road traffic system are interrelated and influence each other, the problems of road safety are directly associated with the geometry and the equipment of streets, particularly in sites where conflicting movements exist, as at intersections. Principles and measures are discussed aiming to decrease the intensity of conflicts in intersections. The examination of accident causes has to be performed in homogeneous parts from various options (geometry of the alignment, pavement condition, traffic conditions, road’s equipment and environment, presence of grade intersections and entries in settlements) and not at individual sites. In the city of Xanthi, Northern Greece the number of accidents with victims is not high, due mainly to the behavior of road users, who does not raise the private car in a role of protagonist. The geometry of road network is susceptible to improvements in relatively few intersections; however interventions could be made for the control of its operation with careful signing and recantation of unfavorable impacts from forced signaling choices.
