Evaluate common highway faults and highlight effective maintenance regimes as preventative measures
Step by step
Solved in 3 steps
- a) What is traffic capacity of a highway link? b) What factors affect the handling capacity of a highway?What are the possible Existing Traffic Variation?What are the two measures used to describe service quality for a two-lane highway? Which of the measures is used to determine LOS for Class I and Class II highways?
- A proposed highway is to be designed with adequate shoulder and clearance ina level terrain with the following: AADT = 25,000 pcu/day D% = 65% K = 9% Estimatethe number of lanes that will provide LOS C. SHOW COMPLETE SOLUTIONThe City of Gainesville and FDOT, in an attempt to proactively address the growing need for capacity in the western area of Gainesville, has identified a potential alignment for a new freeway to UF campus. The FDOT district has contracted you to design this new freeway and identify any additional concerns with this potential freeway. Note that this is an open question, and you may need to make the following assumptions during your work: Lane width (e.g., 12 ft. or 11 ft) Shoulder width (e.g., 6 ft.) Interchange density (e.g., 1 interchange/2 miles) Number of lanes (e.g., 3 or 2 lanes each direction) Hourly volume V= * D*AADT (e.g., =10%, directional distribution D=50%) A design structural number (e.g., SN= 5.0) The following traffic characteristics are expected on this freeway: AADT=30,000 veh PHF=0.95 85% passenger cars Two 2-kip single axles 7% RVs One 10-kip single axle One 24-kip tandem axle 5% single-unit trucks One 12-kip single axle Two 32-kip tandem axles 3% tractor-trailer…a highway that has a superelevation. Provide the location (international or local) and if possible include the specifications of the said highway. Provide at least 3 examples.
- The improper alignment of road will not result in A. Increase of construction cost B. Increase of maintenance cost OC. Increase of population D. Increase of accidentsb) The vertical alignments of two roads A and B are to be designed with speeds 60km/hr and 80km/r, respectively. Differentiate between the two roads in terms of the level of applicable design standards and the expected cost of implementation.Look or research for a highway that has a superelevation. Provide the location(International or local) and if possible include the specifications of the said highway. Provide at least 3 examples.
