What is the capacity of a freeway with 2-lanes in one direction, 10 ft lanes, 1 ft shoulders and 4 ramps within a six-mile stretch? Show Work Correct Answer: 2335
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…

Three designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative. Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15%. Show that the result is the same using the present worth, equivalent annual cost, benefit–cost ratio, and rate-of-return methods.
