- QUESTION 1 How many merging conflicts are present at a 4-leg intersection where each leg is a single lane approach, as shown above?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. Examine the fulfilment of traffic signal Warrants 1 (Condition B) using the MUTCD 2009 standards. Minor Rd. (Higher Major Rd.

W1B is metThe following diagram illustrates the number of conflicting points at a 4-approach unsignalized intersection with one lane for each approach. The conflicting points are classified as points for merging, diverging, and crossing. How many conflict points will there be if the intersection geometry is changed to two off-set “T” intersections? Scratch your solution and label all conflicting points by classification.
- Briefly describe the traffic characteristics associated with each of the levels of service for basic freeway sections.An undivided multilane highway segment has the following characteristics: • Six lanes (three lanes in each direction); Lane width of 11 ft; • Speed limit of 45 mph; Right shoulders is 4 ft wide; • There are approximately 25 access points over a 2-mile section of this roadway, in each direction. Calculate the FFS at this highway section and then determine the level of service (LOS) when the flow rate is 1100 pc/h/In. (Write the answer for the LOS in the box below).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
- 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 secQ1 (A): Name and draw an interchange that contains one-way diagonal ramps in each quadrant and with two at-grade intersections provided on the minor road. (B): Speak briefly about the six warrants that according to the AASHTO should be considered when determining if an interchange is justified at a particular site. 2 log signalizedA six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The traffic stream consists of mostly commuters with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service? (Write the letter only)

Response Feedback: NBTH with NBLT, NBTH with NBRT EBTH with EBLT, EBTH with EBRT SBTH with SBLT, SBTH with SBRT WBTH with WBLT, WBTH with WBRTWhich of the following is/are interchanges? Please check all that apply. O Partial Cloverleaf O At -Grade lInterchange O Single Point Urban Interchange (SPUI) All Directional Four Leg O Full Cloverleaf1- You are assigned to evaluate the level of service for a section of a six-lane rural highway that stretches along a level terrain with shoulder width of eight ft and lane width of twelve ft. The average annual daily traffic is fifty-five thousand vehicles per day with ten percent trucks, five percent buses, and three percent recreational vehicles. The peak hour factor is 0.80 and the directional split is fifty-fifty. The distance between consequent interchanges is two miles. Calculate the level of service for this highway section and show your calculation steps.
