QUESTION 3 What is the intersection sight distance (ft) needed at a yield controlled intersection for a passenger car to turn left onto a 2- way, 2-lane road with a design speed of 50 mph? [round to the nearest foot]
Lane groups are used during signal design to allocate green time among traffic movements at an intersection. What lane group(s) should be defined for the north-bound approach? Intersection layout is shown in the figure below. All approaches have an exclusive left-turning lane. The right lane is shared between through and right turns. a. 60 ft. C. 48 ft. North-bound G=+3% There should be two lane groups. The left turn lane is its own lane group (Lane Group #1). The rest lanes belong to Lane Group #2. O b. There should be two lane groups. The right-side lane is its own lane group (Lane Group #1). The rest lanes belong to Lane Group #2. There should be just one lane group, which contains all the lanes from that approach. O d. Any of the above. ause it's shared

Problem-Traffic Engg. A two-phase signalized intersection is designed with a cycle time of 120 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)
answer no.2 only
A two-phase signalized intersection is designed with a cycle time of 100 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)
Determine whether the criteria for installation of multi-way stop control are satisfied for an intersection with a total entering volume of 365 veh/h on the major street approaches, 355 veh/h on the minor street approaches, and 8 crashes within the last 12 months that could be avoided had multi-way stop control been in place. Criterion for major road traffic volume: Yes, this criterion is satisfied. No, this criterion is not satisfied. Criterion for minor road traffic volume: ○ Yes, this criterion is satisfied. No, this criterion is not satisfied. Criterion for crashes: Yes, this criterion is satisfied. No, this criterion is not satisfied.
