Ina road-intersection near Dhaka, average 120 cars make right-hand turns in every hour. Road planner wants to put in a 3-vehicle right- hand turn lane in the intersection to avoid blocking of thru traffic. Determine if 3-vehicle right-hand turn lane satisfy the following design criteria: Red light time of right-hand traffic is 30 seconds Right-hand turn lane must be sufficient 90% of the time.

A two-lane minor road intersects a two-lane undivided major road at 90 degrees, forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 50 m from the center line of the outside lane of the major road and 14 m from the center line of the nearest lane of the minor road. A passenger car on the minor road would like to cross the major road. Using the AASHTO procedure, determine the maximum speed that can be allowed on the minor road if the design speed on the major road is 80 km/h. Assume a 3% approach grade for the minor road. Note: 1km/hr = 0.62mi/h, 1ft = 0.3048m

Q3- A minor road carrying 100 veh/h on each approach for 8 hours of an average day crosses a major road carrying 260 veh/h on each approach for the same 8 hours, forming a cross intersection. The 85th-percentile approach speed of major roads is 35 kph. In addition, the multiway stop is considered as an interim solution. Determine whether a multiway stop sign is justified at this location if the following conditions exist: 1. The pedestrian volume from the minor street for the same 8 hours traffic volume is 110 ped/h. 2. The average delay to minor-street vehicular traffic during the maximum hours is 40 sec/veh. 3. There is an average of 18 crashes for the last 3-years that may be corrected by installing a multiway stop control.
a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 3.3 meter lanes with a 1.2 meter right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 8% large trucks and buses and 2% recreational vehicles. the driver population factor has been estimated at 0.95. what will the los on this highway be on a 4% upgrade that is 2.4 kilometers long if the speed limit is 90 km/h and there are 9 access points per mile
