A two-lane minor road intersects a two-lane 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 40 ft from the minor road. If the speed limit were 45 mi/h on the major road and 25 mi/h on the minor road, determine the minimum distance that the building can be located from the centerline of the outside lane of the major street.

At a three leg (T) intersection, the two-way peak hour volume on
the minor road is 450 veh/hr and that on the major road is 650
veh/hr. As a Traffic Engineer, what type of intersection control
will you propose? What is the basis of your proposal?

A major road with a design speed of 90km/h intersects a minor
road whose design speed is 50km/h. If the right of way of the main
road is 20m while that of the minor road is 10m and that the two
roads are perpendicular to each other, calculate the size of the
sight triangle.
NOTE: The right of way is measured from the centre of the road.

A two-lane rural highway, four-leg intersection will have its
stop control replaced by a signal control. Compute the expected
average total crash frequency (all types, all severities) after the
change for the following conditions:
Expected average crash frequency before change: 23 total
crashes/yr
AADT on minor road: 1500 veh/day
AADT on major road: 5000 veh/day

Assume that a two-lane small road crosses a two-lane main road
at a right angle making a four-leg intersection where the traffic
on the small road controlled by a yield sign. A shopping mall is
located 108.24 ft from the centerline of the outside lane of the
main road and 12 m from the centerline of the nearest lane of the
minor road. Determine the maximum velocity (in km/h) that can be
allowed on the small road if the speed...

A traffic signal on the four-leg signalized intersection is
designed based on the information below. Please answer the
following questions. The startup lost time per phase is 2.0
seconds, and the clearance lost time per phase is 1.5 seconds. The
deceleration rate of the vehicles is 3.4 m/s2, and the
average length of the vehicles is 6.0 m. The lane width of normal
lane is 3.3 m, and the turn bay width is 2.8 m. Please ignore the
median width...

The road becomes a class-III two-lane highway after reaching a
long bend in the road. The speeds don’t typically change off-peak
at the transition, and width/clearance/access are consistent after
the transition too. There are 50% no passing zones. What is the LOS
of the two-lane highway?

A 6-lane two-way arterial road has a maximum flow of
6,000 vehicles per hour on one
direction. It is operating at 3,600 vehicles per hour at time, t=0.
A collision occurs,
blocking the two lanes, and restricting the flow of the third lane
to 1,800 vehicles per
hour. After 45 minutes, the MMDA and police have cleared the
incident and traffic returns
to normal as soon as the queue has already dissipated.
