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.

This is a three-part problem. Two sets of students are collecting traffic data at two roadway stations, station 130 + 00 and station 145 +00. Observations at station 130 + 00 show that five vehicles passed that section at intervals of 0, 3, 4, 3, and 5 sec, respectively. If the speeds of the vehicles were 50, 45, 40, 45, and 50 mph respectively. Note: Stationing is fundamental to highway plans. A station is the horizontal measurement along the Construction Survey Line of a project. Distances are measured and points are identified on plans with reference to station numbers. One hundred feet is equivalent to one station. Highway stationing might be compared with a rope having knots at 100-foot intervals. The beginning end of the rope would be 0, the first knot at 100 feet would be Station Number 1 and would be written as 1+00. The second station number would be 2 (which is 200 feet from the beginning) and would be written as 2+00, and so on. Part A. Determine the time mean speed, in mph.…
