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.

7.12 The saturation flow rate of an approach to a pretimed signal is 6000 veh/h. The signal has a 60-second cycle with 20 seconds of effective red allocated to the approach. At the beginning of an effective red (with no vehicles remaining in the queue from a previous cycle), vehicles start arriving at a rate v(t) = 0.4 +0.01t + 0.00057+² (where v(t)) is in vehicles per second and t is the number of seconds from the beginning of the cycle). 30 seconds into the cycle the arrival rate remains constant at its 30-second level and stays at that rate until the end of the cycle. What is the total vehicle delay over the cycle (in vehicle- seconds), assuming D/D/1 queuing?
Plz, solve this problem. Transportation Engineering-2 A four-lane highway (2 lanes in each direction) with 3.65m lanes has a horizontal curve designed for a 380 m centerline radius, and a 110 km/hr design speed. The grade is level. Use a driver perception reaction time of 2.5 sec and a vehicle deceleration rate of 3.4 m/sec2. Determine the closest distance any roadside object may be placed to the centerline of the inside lane of the roadway.(note: Do not round any value. Use calculated values).
A rail transit system has prescribed the following factors:1. Peak hour demand = 30000 passengers/hr2. Minimum required speed = 55 ft/sec3. Deceleration = 3 ft/sec24. Safety factor = 1.455. Vehicle length = 80 ft6. Allowable vehicle capacity = 150 pass/veh7. Guideway utilization factor = 0.838. Minimum headway = 110 secHow many cars should the train consist of to provide adequate passenger capacity?
