| Summary: | and accident potential. Therefore, identifying relationships and the roadway characteristics for tangents and horizontal associated with elements of the highway. Previous research between speed distribution measures of free-flowing passenger criteria, and speed data were collected at the midpoint of curve. The speed reduction from the tangent to the curves. The study also analyzed the speed difference between distinguish consistent and inconsistent roadway features. drivers ample opportunity to reach their desired speeds. geographic regions were identified based on selected greater than 150 meters to ensure speed differences between has identified a direct relationship between speed variance horizontal curve was a function of the curve radius. The identified a relationship between mean speed, speed variance, Incorporating the 10 km/h speed differential between features lengths greater than 250 meters, the radius should be on rural two-lane highways is needed to address driver error reduction based on the curve radius. Mean speed and speed research documents that tangents greater than 250 meters give roadway characteristics. Horizontal curves from four roadway, the length of the tangent, and the radius of the Specifically, the focus of this study was on understanding standard deviation were related to the posted speed of the successive horizontal features and found an average speed suggested by Lamm, a minimum radius following long tangents the preceding tangent and the curve midpoint. The results the relationship between mean speed, speed variance, and the tangent and horizontal curve are less than IO km/h. Understanding the behavior of speed population distributions vehicles and roadway characteristics could be used to was recommended. For horizontal curves following tangent |
