Determination of safe operating speed of cars running on circular curves in Vietnam conditons

Abstract

One of the most important goals in road construction is to provide safe driving at high speeds in order to reduce trip time and increase investment efficiency. However, when a car run on a circular curve, it will be affected by centrifugal force, causing the vehicle to be in danger of overturning and sliding on the road surface, causing traffic insecurity. Therefore, it is necessary to study and determine the operating speed when cars run on a circular curve to ensure traffic safety. Based on analyzing the relationship between the speed and radius of the circular curve to the stability condition of the car, the articlehas researched and recommended the operating speed to ensure safety when cars run on circular curves with minimum radius and normal radius. The research results of the article are the basis for the management agency to determine the reasonable operating speed of the route.
