Solved in 2 steps
- A minor 2-lane roadway with design speed of 45 mph crosses a major 2-lane roadway with design speed of 50 mph at 90 degree angle at an at-grade T-intersection. All lanes are 12 ft wide. If a stop sign is installed on the minor road, determine the dimensions ofallrequired clear sight triangles at this intersection for passenger cars(Case B, stop sign control on the minor road).The main reason why there are a lot of accidents happening on an intersection is THE LACK OF TRAFFIC SIGNALS. Choices: A. True B. FalseA signaled intersection can improve the traffic density of a certain road segment. Choices: A. True B. False
- State the principal difference between interchange and other forms of intersection.Give way sign is an effective control technique at the intersection of two arterial roads with similar flows.A two-lane minor road intersects a four-lane undivided major road at 90 degrees,forming a four-leg intersection with traffic on the minor road controlled by a stop sign. The designspeed on the major road is 80 km/h. The approach grade on the minor road is 5%. A single unit truckon the minor road would like to make a left turn onto the major road. Using the AASHTO procedure,determine the minimum sight distance required on the major road for the truck to make a left turnonto the major road.
- A road with a design speed of 55 mph has a utility pole located 27 ft from the edge of travel lane. If the ADT for the road is 1,850 vpd and the sideslope slopes down at a 1V:4H grade, is the utility pole located within the clear zone?Determine the PTSF in each direction for a 4.5 mi (7.2 km) two-lane highway segmentin level terrain. Traffic volumes (two-way) are 1100 veh/h. Trucks: 10%; RVs: 7%; PHF:0.97; directional split: 60/40; no passing zones: 40%.Two adjacent signalized intersections along a major arterial are 650 ft apart (stop line to stop line distance). If the space mean speed between these two intersections is 22 mph, what should be the signal offset of the downstream intersection relative to the upstream intersection? Group of answer choices 20.0 sec 13.5 sec 40.0 sec 29.5 sec
- b) Figure 2 indicates the layout of the unsignalised intersection between a major road and a minor road. If the stopping sight distance of vehicle ‘A’ on the minor road is 60m at a speed of 50km/h and that of vehicle ‘B’ on the major road is 80m at a speed of 60km/h, determine the adequacy of the intersection sight distance provided that will ensure that vehicle ‘A’ safely crosses the major road without colliding with vehicle ‘B’. The distance of vehicle ‘A’ to the building is 15m represented by ‘x’ in the figure.A rural collector is to be constructed in an area of rolling terrain where the ADT is 650 veh/day. For this situation, determine the following design values. (a) Minimum design speed (b) Recommended lane width (c) Preferable shoulder width (d) Maximum gradeA 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
