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 crasheswithin 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.Determine whether the installation of a multi-way stop control is justified.○ Yes, a multi-way stop control should be installed.O No, a multi-way stop control should not be installed.

ramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.9. If the road is expanded to four 11-foot lanes with a 2-foot right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and peak-hour factor, what is the new LOS and estimated density? P-22 Chapter 6 Problems hour. What would be the LOS before and after the heavy vehicles are allowed on the upgrade (assuming 50% SUTs and 50% TTs.)? 6.21 A multilane highway has four lanes (two lanes in each direction) and a measured FFS of 55 mi/h. The directional peak-hour volume is 1900 vehicles (the peak-hour factor is 0.80). One upgrade is 5% and is 0.62 mi long. Currently, heavy vehicles are not permitted on the highway, but local authorities are considering allowing heavy vehicles on this upgrade. If this is done, they estimate that 150 heavy vehicles will use…
Q3c. At a three leg (T) intersection, the two-way peak hour volume on the minor road is 500 veh/hr and that on the major road is 600 veh/hr. As a Traffic Engineer, what type of intersection control will you propose? What is the basis of your proposal?
Need type answer The T-intersection has 2,400 collision incidents over the last three years. The annual daily traffic is shown in the figure below Determine the accident rate of the intersection.
The details of a 12-hour volume study for a 4- leg road junction are tabulated below. The N-S major road has two through lanes on each approach while the E-W minor road has one through lane on each approach.

Answer True/False to the following: 1) A strong degree of uniformity in the design of traffic facilities guarantees uniform reactions from drivers. 2) The traffic signal warrant that several agencies do not recommend using is the Peak Hour Traffic Volume warrant. 3) It is reasonable to use a higher unit extension time value on an actuated signal approaches with higher speeds. 4) According to the Roundabout Design Guide volume-to-capacity ratio of 0.85 must be the threshold for acceptable operation at a roundabout entry.

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

Traffic volume is 2578 veh/hr with 687 vehicles arriving in peak 15 minutes.There are tow lanes, 12 percent trucks(30/70 split for SUT/TT), the length of the road is 1.8 miles long with a 3.5 percent grade. calculate the analysis flow rate?
A T-intersection is the meeting point of a two-lane minor road (one lane in each direction) with a two-lane undivided highway (one lane in each direction). The vehicles approaching from the minor road must stop, but the vehicles along the highway do not need to stop. Draw all the traffic movements and count the number of conflict points (i.e., major and minor).
QUESTION 1 How many merging conflicts are present at a 4-leg intersection where each leg is a single lane approach, as shown above?
