If G₁=2 % and G₂=-4%, the required vertical curve is a crest curve. O True False QUESTION 5 A vertical curve is needed to join to tangents; G₁-2% and G₂-5%. Assuming the worst case scenario for braking, and the AASHTO recommended values for deceleration and perception-reaction time, calculate the minimum length of curve (ft) needed to satisfy the comfort criteria. The design speed is 50 mph.

Highway Surveys and Location

Surveying is an operation in the civil engineering domain that requires collecting and identifying data regarding an area of land and topography. The data that is collected can be helped to plan and undertake the construction process. Civil engineers perform surveys to gather three-dimensional information regarding a particular area. Engineers specify several points on the surface of the earth and relationship between points, and the distance and angles between the points are evaluated. The data from this evaluation guides in drawing plans regarding buildings and structures.
