Safety Audit for Weaving Maneuver: A Driver Simulation Safety Analysis

It is well known that the weaving maneuver is one of the most difficult operation to analyze in terms of road safety. The need for research directed towards a functional analysis of roundabouts characterized by the weaving lane, comes from the necessity to ensure high safety standards through appropriate design procedures and safety audit; particularly when European Community Countries were required to transpose the Directive 2008/96/CE, which imposes a significant reduction in the road accident rate. Mainly in Italy, there aren’t documents about road geometrical design that provide detailed methods to plan weaving areas, but the ones that exist only suggest using probabilistic methods, leaving designers free to choose the statistical distribution. This study proposes an analysis of driver behavior on different weaving lanes in various traffic conditions performed on an interactive driving simulator. Four different lengths of weaving lane combined with four different traffic flow conditions were simulated and the different drivers’ performance have been analyzed. Moreover a hazard analysis has been conducted. It has been observed that increasing length of the weaving lanes is effective only when the traffic flow conditions exceed a certain threshold. The general results highlighting the advanced method of driving simulator can ensure the reliability of measures and, also, it can show the relationships between road geometrical characteristics and drivers' behavior.
