The reaction time used for road safety design is:

The purpose of installing edges lines is generally based on the following I. To discourage travel on road shoulders. II.To make driving safer and more assured particularly at night and during inclement weather conditions. IlI.To act as a guide past object which are close to the edge of the pavement and which constitute a hazard. IV.To prevent parking at or near intersections.

Minimum K value vertical curves should be selected on the basis of three controlling factors: I. Sight distance is a requirement in all situations for driver safety. II.Appearance is generally required in low fill and flat topography situations. III.Riding comfort is a general requirement with specific need on approaches to a floodway where the length of depression needs to be minimized. IV.Vertical alignment should fit into the natural terrain earthwork balances.

The safety of an intersection can be improved by he provision of right and left auxilliary turning lanes. Turning lanes also improve intersection capacity and traffic flow.They are particularly important the volume of trafic making these moves is high or the through or oncoming traffic flows are high. Provision for turning lanes an generally be provided in the following ways I. Shared turning and through lane II. Flaring and tape III. Separate lane for deceleration and storage IV. Establishment of a trafic Island
