A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
Determine the practical stopping distance (m) for a road with speed limit of 49kph and grade of 0%
55 mph roadway with two northbound through lanes (both are 11 feet in width) through an intersection. Beyond the intersection, the lanes merge into one lane. Please calculate the merge taper AND the distance the sign must be place AHEAD or upstream of the beginning of the merge.

- Problem Determine the level of service? for six lanes undivided level highway. The width of lane, shoulder on the right side, and shoulder on the left side are 10 ft, 2 ft, and 2 ft respectively. The directional hour volume is 3500 Veh/h. The traffic composition includes 15% trucks and 1% RVs. The peak hour factor is 0.80. Unfamiliar drivers use the road that has 10 access points per mile. The design speed is 55 mi/h. Discuss possible modifications to upgrade the level of service? (Verify your answer)arrow_forwardQ3: A four-leg intersection with no traffic control is formed by two-lane roads with the speed limits on the minor and major roads being 15 and 25 mi/h, respectively. If the roads cross at 90° and a building is to be located at a distance of 45 ft from the centerline of the outside lane of the major road, determine the minimum distance at which the building should be located from the centerline of the nearest lane on the minor road so that adequate sight distances are provided.arrow_forwardComplete answerarrow_forward
- select all correct options.arrow_forwardA 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 = 0.3048marrow_forwardA developer has requested permission to build a large retail store at a location adjacent to the intersection of an undivided four-lane major road and a two-lane minor road. Traffic on the minor road is controlled by a stop sign. The design speeds are 60 and 80 km/h on the minor and major roads, respectively. The building is to be at a distance of 20 m from the centerline of the near lane of one of the approaches of the minor road. Determine where the building should be located relative to the centerline of the outside lane of the major road in order to provide adequate sight distance for a medium single-unit truck on the minor road to proceed safely across the intersection after stopping at the stop line. Assume a 3.6-m lane width and a 3-m distance from the stop line to the near edge of the major road.arrow_forward
