A large billboard is to be constructed by the side of a two-lane road, on the inside of a horizontal curve, 27 feet from the edge of the innermost lane. If the road is located in a retirement community (where the design speed is 45 mph, the maximum superelevation is 4%, lanes are 12 feet wide, and the expected perception-reaction time is 3.5 seconds), is the billboard location acceptabl

The through movement passenger car equivalents (pcphpl) for each approach of Vine and Maple Streetsintersections obtained from a traffic survey as shown in the following diagram. Vine Street for NSmovements 1s 48 ft wide and Maple Street for EW movements is 60 ft wide. There are two throughmovement lanes and one left-tum lane in each approach. The yellow times for Vine Street and MapleStreet through movement and left-tum phases are 4 second and 3 seconds per g_hase, respectively. TheAll-red for each phase is 2.0 seconds and the ost time is 5 seconds per phase. Pedestrian walkmgspeed is 3.5 ft/sec. Assuming equal distribution of traffic on the two through-movement lanes in eachapproach and a saturation flow rate of 1,900 pcphpl. A 3-phase fixed timing signal plan (namely, aprotected left-turn phase, a NS phase, and an EW phase) is suggested.I) In the diagram, the through movement volume is for 2 lanes and left tum volume is for one-lane.2) Determine one N-S or E-W left tum phase on the…

4. Using the method learned in class, what is the LOS for a weaving section with the lane configuration and design volumes shown, given a section length of 1800 ft, peak hour factor of 0.9, and heavy vehicle adjustment factor (fHV) of 0.94? Directional design volumes (veh/hr): 3700 10 520 180

A class IIl two lane highway in rolling terrain services a small built-up area. It has a base free flow speed of 50 mph., the highway has 11 foot lanes and 4 foot clear shoulders on both sides. There are 12 access points/mile, and 85% no passing zones. Current traffic is 525 vehicles per hour, with 12% trucks, 3% RVs, and a PHF of 0.89. The directional distribution is 60-40. What LOS is expected on this facility?
