Upgrading a highway A highway must be constructed to con- nect Village A with Village B. There is a rudimentary roadway that can be upgraded 50 mi south of the line connecting the two villages. The cost of upgrading the existing roadway is $300,000 per mile, whereas the cost of constructing a new highway is $500,000 per mile. Find the combination of upgrading and new construction that minimizes the cost of connecting the two vil- lages. Clearly define the location of the proposed highway. –150 mi- A B 50 mi 50'mi Old road

What are the negative impacts of constructing highway through an existing farmland to the community?
Principal criteria in designing highway. Explain each criteria.
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.
4. TXDOT is working on the design of I-69 north of Victoria. They project a demand volume of 52,000 vehicles per day with a K factor of 0.12 and a directional distribution of 56/44 in level terrain with a target LOS of B and 17% trucks and buses. They plan to have roughly one diamond interchange every 2 miles. What number of lanes is required to achieve these design requirements? What LOS would occur for a typical 4-lane rural interstate design? DHV = AADT * K * D DHV – design hourly volume AADT - average annual daily traffic K- peak hour adjustment factor D- directional distribution (make design conservative)
3. What factors influence the choice of a route for a new highway?
A direct factor that directly affects the required right of way necessary to construct the road.
a) What is traffic capacity of a highway link? 5) What factors affect the handling capacity of a highway?
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.
What are the positive impact of onstructing highway through existing farmland to the community?
The 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…
