Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

3. Refer to the following illustration; veh#2 is driving with the speed of 60mph, following veh#1
whose speed is 50mph. The lead car suddenly breaks to a stop within a 278 ft distance. Assume
the friction factor is unknown, but both cars operate with the same deceleration rate, and
veh#2 has a default reaction-perception time by AASHTO. If the roadway is level, estimate the
minimum distance between the two cars so the collision can be prevented.

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s?. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 15 ft/s?. Determine the minimum distance d between the cars so as to avoid a collision. -d -
Q3/A subway traveling at 40 km/hr decelerates as it reaches point A and slows down with a constant deceleration. Its reduced velocity is noted to be 30 km/hr as it passes point C.

2.30 An engineering student is driving on a level roadway and sees a construction sign 500 ft ahead in the middle of the roadway. The student strikes the sign at a speed of 25 mi/h. If the student was traveling at 55 mi/h when the sign was first spotted, what was the student's associated perception/reaction time (use practical stopping distance)?
Two drivers each have a reaction time of 2.5 seconds. One is obeying a 90 km/h speed limit, and the other is travelling illegally at 108 km/h. How much distance will each of the drivers cover while perceiving/reaction to the need to stop, and what will the total stopping distance be for each driver (using practical stopping distance and assuming roadway grade g = -2.5%). Longitudinal friction coefficient (fi) can be calculated by the equation f = 1.0371 V-0.2729 where V vehicle speed in km/h.|
