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.

which type of urban road would have free-flow traffic characteristics? 1. Arterial 2. Local 3. Freeway 4. Collector
A new four-lane divided multilane highway (two lanes in each direction) is being planned with 12-ft lanes, 6-ft shoulders on both sides, and a 50-mi/h speed limit. One 3% downgrade is 4.5 mi long, and there will be 4 access points per mile. The peak-hour directional volume along this grade is estimated to consist of 1800 passenger cars, 140 SUTs, and 60 TTs. If the peak-hour factor is estimated to be 0.85, what level of service will this segment of highway operate under? What is the percent trucks - PT? What is the value of the passenger car equivalence factor - ET? What is the heavy vehicle factor - fHV? What is the median adjustment factor - fM?
A 3.25-mile segment of undivided, four-lane highway is primarily on level terrain. The highway segment does, however, contain one sustained grade of 2.5% that is 3,200 ft long. Other relevant information include: Base free-flow speed = 65 mph %3! 11-ft lanes • 4 ft clearance at the roadside (right side) • 20 access points/mile Peak-hour volume = 1,900 veh/h 13% trucks; 2% RVs • PHF = 0.90 • Familiar facility users At what LOS is the highway expected to operate? (Hint: Three different analyses will be needed: a) the level terrain portion of the highway, b) the 2.5% upgrade portion of the highway, and c) the 2.5% downgrade portion of the highway.)
(PLEASE USE FIGURE 14.5 TO ANSWER THE QUESTION) A consecutive upgrade consists of two sections, the first of 2 percent grade and 5000 ft long, and the second of 6 percent grade and 5000 ft long. Trucks comprise 10 percent of traffic. And recreational vehicles comprise 6 percent. Determine: the equivalent grade the PCEs
