Safety Evaluation for the Highway Alignment with 3D Visual Simulation

Abstract:

In the current highway design, poor coordinate of the alignment has a great effect on the sight distance which would increase the danger and difficulty of driving. For this reason, safety checking for highway alignment is required by the current standard. In this paper, 3D simulation technique was used to model the real scene of driving. Based on the concept of the preview sight distance (PVSD), two typical coordinates of alignment in practice were discussed. Although the current standard requirement is met, it is demonstrated that the alignment in the location of a minor horizontal curve and combination of a tangent with a circular curve could still provide driver confusing information. Some recommendations were suggested so as to improve the highway alignment design.
