2.12 Design Hourly Volume on a 2-lane urban radial road. The road has a 2-way ADT of 6915 vehicles per day. Transportation planners forecast that this road will carry 22.000 vpd ten years from now. What will be the road's DHV ten years from now? Will more lanes need to be added by that future year? Assume that an urban radial road has a capacity of 2000 veh/hr/lane. A rural highway is to be designed as a passenger-car-only facility for an AADT of 35,000 vehicles per day. The lane capacity is (1800 P.c/hr/lane), with 60% of the peak-hour traffic traveling in the peak direction. Determine the number of lanes required.

A proposed improvement will widen a two-lane rural highway from 9-ft-wide (per lane) to 11-ft-wide (per lane) if the highway has an AADT of 2100 veh/day. If there are an average of 25 crashes per year on the segment proposed for improvement, and 67% of the crashes are of the type targeted by the improvement, estimate the expected number of crashes (per year) after the improvement is constructed.
A new 50 km freeway was required to constructed between two cities with design speed 70 mph, the expected 20 year DHV was 12000 vph on a regular weekday, rolling terrain, PHF pf 0.95, directional split of 65%, a heavy vehicle adjustment factor of 0.85 and the suggested L.O.S to reach end design period is B (v/c=0.54), if the one lane cost per kilometer was 25000$. What will be the saving of money if the operating L.O.S at the end of design period change to be L.O.S C (c/v=0.77)?Assume: the lane and shoulder width are ideal, lane capacity * 2000 pc/hr

a/ There was a need to know the volumes traffic for a rural project where 24 hrs. flows were counted on Thursday, Friday and Saturday in December as follow, Thursday = 8000, Friday = 8000 and Saturday = 10000. Q2 /b/ Design data is required for improvement of two – lane of two – way highway with central reserve. The current traffic in 2016 expressed by AADT is 3000 vehicles. The improved road with a design life of 20 years will opened to traffic in 2021, the estimated annual growth rate of traffic is 8%, K-factor is 12% of AADT and D (Directional distribution) is 55% of total traffic.

A 6-lane urban freeway is suggested to be designed with the following data: F.ADT = 45000 vpd, design hour factor= 0.12 and directional split = 65%. Rolling terrain, 10% trucks, 5% buses, 6% Rvs, PHF is 0.91 and all traffic are commuters. Then based on the HCM 2000 procedure, the equivalent passenger- car hourly flow rate is about

Consider the problem of traffic flow on a three-lane (one direction) freeway which can be described by the Greenshields model. One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take several hours. It is estimated that the capacity at the work zone will be reduced by 30 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 60 mi/h and the jam density is 130 veh/mi/ln. It is estimated that the demand flow on the highway during the emergency repairs is 86 percent of the capacity. Using the deterministic approach, determine the following for the expected repair periods of 1 h, 1.5 h, 2.5 h, 2.75 h, and 3 h.

QUESTION 10 A two-lane, one-way, rural freeway segment is being designed to service a demand volume of 4,000 vehicles per hour. The PHF is expected to be 0.95. If the combination of trucks, buses, and recreational vehicles is represented by a heavy vehicle adjustment of 0.85, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.
