Abstract: Research of human factors in highway engineering may be seen to include two main areas: the effect of geometric design on driver behavior, and the consideration of driver behavior variability. A critical review of pertinent ...

Abstract: The procedure of road safety audit (RSA), which originated in Great Britain and is now being spread in several countries around the world, can be incorporated in the framework of designing, constructing, and operating road ...

Abstract: Preparing the grading plan of the side slopes on a highway section is an effective way to obtain an overall three-dimensional view of the entire design area, and a design fitting the roadside topography. Flattening the ...

Abstract: Required stopping sight distance (SSD), used to calculate the minimum rate of vertical curvature or the minimum length of a crest vertical curve (CVC), is usually calculated on the assumption that the grade of the braking ...

Abstract: Cantilever retaining walls are required to retain earth at a change in ground elevation. As the nonseismic design of cantilever retaining walls is well discussed elsewhere, this paper deals mainly with seismic considerations. ...
