• Abstract:
  Current design practice for horizontal curves assumes that vehicles follow the path of the highway curve with geometric exactness. To examine the adequacy of this assumption, photographic field studies were conducted of vehicle maneuvers on highway curves. Results of the field studies indicate that most vehicle paths, regardless of speed, exceed the degree of highway curve at some point on the curve. For example, on a 3-degree highway curve, 10 percent of the vehicles can be expected to exceed 4.3 degrees.
