- What are the possible Existing Traffic Variation?arrow_forwardThe 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…arrow_forwardWhat are the parameters in designing highway facilities and safety?Enumerate at least five safety features that you see on the road, then briefly describe each.arrow_forward

Choose any area of the Philippines where you believe a road infrastructure would be necessary to enhance the city's or province's current transportation system and stimulate the local economy.

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)arrow_forward
