Answer to Problem 1P

30 mi/h

Explanation of Solution

Given information:

In mountains terrain is designed to carry volume of 800 veh/day.

  Traffic and Highway Engineering - With Mindtap, Chapter 15, Problem 1P , additional homework tip  1

For a rural collector highway located in mountains terrain is designed to carry a design volume 800 veh/day is given Table 15.1 from the textbook.

From the table the design speed for 800 veh/day is 30 mi/h.

To determine

(b)

Lane and usable shoulder lengths for the rural collector highway.

Expert Solution

Answer to Problem 1P

Lane= 12ft

Shoulder = 5ft.

Explanation of Solution

Given information:

In mountains terrain is designed to carry volume of 800 veh/day.

For a rural collector highway located in mountains terrain is designed to carry a design volume 800 veh/day is given figure 15.5 from the textbook.

  Traffic and Highway Engineering - With Mindtap, Chapter 15, Problem 1P , additional homework tip  2

From the figure 15.5 the width of lane is 12ft.

Width of shoulder is total 10 ft on each side of road is 5ft.

To determine

(c)

Maximum desirable grade for the rural collector highway.

Expert Solution

A rural collector highway located in a mountainous terrain is designed to carry a design volume of 800 veh/day. Determine the following: (a) a suitable design speed, (b) lane and usable shoulder widths, (c) maximum desirable grade. Repeat Problem 1 for an urban freeway in rolling terrain.
A two-lane rural highway carries a peak hour volume of 465 (vph) and has the following characteristics:   Roadway: 60mph design; 11 foot lanes, 2 foot shoulders; rolling terrain; 60% no-passing zones; length = 3 miles.   Traffic: 70/30 directional split; 4% trucks; 2 percent recreational vehicles; 1 percent buses; PHF = 0.95   a) What Level of Service will the highway operate under during peak periods?   b) What is the capacity of the highway? Explain why this is less than 2,800 (vph)?
