The 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.

The Intersection design: a. Describe the various principles involved in the design of at-grade intersections and the different types of at-grade intersections. Also, give an example of an appropriate location for the use of each type.
It is defined as an at-grade crossing of two or more roadways. Choices: A. Intersection B. Block C. Street D. Highway
State the principal difference between interchange and other forms of intersection.
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).
