Highway Capacity and Level-of-Service Analysis

Freeways

A new segment of freeway is being built to connect two existing parallel freeway facilities, in an urban area. The following traffic and roadway characteristics are expected:

Traffic Characteristics

• AADT = 92000 veh/day

• K = 13%

• D = 50%

• PHF = 0.92

• 8% trucks and buses

• 3% RVs

• Primarily commuters

Roadway Characteristics

• Grade in peak direction: 1.42 miles, 3.25% upgrade

• Interchange density = 1.8 per mile

• Lane widths = 12 ft

• Shoulder widths = 4 ft

1. Determine the number of lanes necessary to ensure that this new freeway segment will operate at no worse than LOS D during the peak hour in the peak direction.

2. How much additional traffic, in the peak direction, can be accommodated before the freeway reaches capacity?

Multilanes

A section of a multilane highway is to be reconstructed to improve the level of service. The section being considered is on a 5.0% upgrade that is 3/4 mile long. The highway currently has 4-lanes (2 in each direction – all are 12-ft lanes) with a two-way left-turn lane in the middle and 4 foot shoulders on the right side. It is to be reconstructed into a 6-lane facility (3-lanes in each direction) undivided facility but, due to commercial development surrounding the highway, must remain in the current 72 foot right of way. There are currently 35 access points per mile and the free flow speed is determined to be 50 mi/h. It is known that the road currently operates at capacity with 420 trucks/buses (no recreational vehicles) during the peak hour, a peak hour factor of 0.95 and all-commuter traffic.

The redesign is to reduce the number of access points per mile to 10 and to reduce the grade to 4.0% for 3/4 mile. It is estimated that the new design will increase traffic by 13%.

1. Determine the lane width and shoulder width combination that will maximize capacity given that the 3 lanes (each direction) must fit within 36ft?

2. For the maximum-capacity lane/shoulder combination chosen above, determine the new design's level of service and density.

i need a research for one of the first built tombs in the world. The selected tomb should have a superstructure. Specifically, focus on the, Evidential, Historical, Aesthetic and Communal Values of the tombs. In other words, determine the specific futures of a tomb in relation to their evidential, historical, aesthetic, and communal values

also Architect, architectural features, construction year and duration, construction materials, construction type, structural features, construction purpose and the features that make it different and significant and the importance of the construction for the society should be included and explained under the headings of Evidential, Historical, Aesthetic and Communal Values in the report. You should illustrate your explanations with photographs which should be referred in your report

a maximum 350-words long

You need to submit the reference files to me as well (preferably as a PDF) and give names to the reference files with the name of the study described in the reference file

1. Sketch and explain the graphical procedures to find the soil memory, i.e., pre-consolidation pressure, , Compression Index, Cc, and Swell Index Cs using drawings and/or diagrams. Why do we introduce them in soil mechanics and engineering?

A continuous and aligned fibrous reinforced composite having a cross-sectional area of 875
mm² is subjected to an external tensile load. If the stresses sustained by the fiber and matrix
phases are 255 MPa and 8.35 MPa, respectively, the force sustained by the fiber phase is 85,800
N, and the total longitudinal composite strain is 1.65 x 10^-3, determine the following:
(20 Points)

(a) Volume fraction of fiber and matrix
(b) The force sustained by the matrix phase
(c) The modulus of elasticity of the composite material in the longitudinal direction
(d) The moduli of elasticity for fiber and matrix phases

How is soil investigation important in civil engineering and give examples.

2. Given a 28-acre watershed with the following land use mix: 8 acres of SFR (38% impervious) on HSG-B soils, 5 acres of SFR (30% impervious) on HSG-C soils, and 15 acres of open space (park and playground) in fair condition on HSG-C soils. Watershed time of concentration is 21 minutes. The design return period 24-hour rainfall depth is 5.25 inches.

d)   The runoff volume from a rainfall of 0.47 inches (watershed inches) =

Answer only if you can draw perfect drawings
Don't attempt if u don't know the answer
Don't send random answers... Only attempt if u know all the four answers perfectly.... Otherwias I will downvote

1) give the planning for 2bhk in autocad and design the model in staad
2)Show the drawing of any industrial truss with perfect drawings
3)write about magnetic water concrete and its hydration
4)give the reference drawings of circular and. Combined footing

For the following, compute and tabulate R or D, T, L, LC, E, M, PC, PT, deflection angles, and incremental chords to lay out he circular curves at full stations (100’). Develop and tabulate the curve data, deflection angles, and incremental chords needed to lay out the circular curves at full- station increments using a total station instrument set up at the PC. (Essentially, develop a table similar to Table 24.2.)

1. Highway curve with R = 1200’, I = 30o00’, and PI station = 45 + 50.00’ 2. Highway curve with T = 131.65’, R = 1200’, and PI station = 67 + 50.00’ 3. Highway curve with R = 900 m, I = 12o30’, and PI station = 4+200.600 m 4. Highway curve with R = 550 m, I = 5o00’, and PI station = 3 + 290.600 m

Design a baseplate for a W24 x 192 column carrying an axial load of P_u = 2000k and bearing on a 8′ x 8′ concrete footing with f′_c = 3ksi (not in mm show work steps by step )

If a beam is loaded in pure bending, where would you expect the maximum compressive and tensile stresses to occur
