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).
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 islocated 185ft from the center line of the outside lane of the major road. The design speed on themajor road is 60 mi/h and the design speed on the minor is 35 mi/h. The approach grade on the minorroad is 3%. A passenger car on the minor road would like to cross the major road. Using theAASHTO procedure, determine the minimum distance required that the building must be from thenearest lane on the minor road
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 two-lane minor road intersects with a four-lane major street at 90 deg, forming a 4-leg intersection with traffic on the minor road controlled by a stop sign. The speed limits were 45 mph on the major road, and 25 mph on the minor road. Determine the intersection sight distance (ISD) when a passenger car wants to make a left turn onto the major street.

It is operating in LOS B with a traffic density of 15.6 pc/mi/ln and a peak-hour factor of 0.85. The freeway is on level terrain with 15% heavy vehicles, and currently has no on- or off- ramps within a distance of three miles upstream and downstream of the mid-point of the analysis section. New interchanges are to be constructed that would result in 6 on- and off-ramps within the distance of three miles upstream and downstream of the mid- point of the analysis section and total traffic volume is projected to double, with the same percentage of heavy vehicles, and the peak-hour factor going to 0.95.
