Evaluation of Transportation Projects

Civil engineers undertake a variety of projects related to construction. Building construction projects, structural projects, highway, road construction projects, transportation projects, etc. Transportation projects are related to public constructions that focus to build new connectivity in public transportation. To improve and maintain existing transport facilities also falls under the domain of transportation projects. Some of its objectives include planning, evaluation, designing, development, finance, construction, reconstruction, demolition, rehabilitation, improvement, acquisition, operation, and maintenance. As per the law, all transport projects are authorized to the construction firm that permits them to change the land area meant for public use.

A delivery truck passes thru the expressway exit ramps at a design velocity of 50 kph. connects with a local road to allow ram traffic to turn right without stopping at an acceleration of 1.57 m/sq.s. The turning roadway has stabilized shoulders on both sides and provides for a one-lane one-way operation with no provisions for a passing stalled vehicle. Super elevation on the turning roadway is 0.08. Determine the minimum radius of curvature for the ramp in meters.

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?
(b) While aligning a high way in a built up area, it was necessary to provide a horizontal circular curve of radius 325 metre. The design speed is 65 kmph, length of wheel base of largest truck = 6.0 m and width of pavement is 10.5 m. Design the following geometric features: (i) Superelevation (ii) Extra widening of pavement (ii) Length of transition curve.
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.)
