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.

Select the true items related to absorption capacity. Select only the four correct answers. Practical absorption capacity is usually less than theoretical absorption capacity. It is the minimum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour. Absorption capacity depends on the vehicle arrival rate at the minor approach. Practical absorption capacity is usually more than theoretical absorption capacity. Absorption capacity does not depend on the flow of the mainstream traffic. Absorption capacity depends on the flow of the mainstream traffic. Absorption capacity does not depend on the vehicle arrival rate at the minor approach. It is the maximum possible number of vehicles from the minor approach that can merge into the mainstream traffic per hour.
