Unformatted text preview: 2/13/2019 NUMBER OF LANES SAMPLE PROBLEM/S: The basic task in designing highways is the determination of the number of lanes needed to 1. A proposed highway is to be designed with meet the given design volume under a specified adequate shoulder clearance in a level of terrain LOS. with the following: AADT= 40 000 pcu/day The procedure may follow trial and error. Thus, the D = 65% anumber of lanes is initially assumed. (validate K= 98 &quot;assumption from the corresponding capacity Estimate the number of lanes that will obtained from the table of values.) provide LOS B. 2. Five vehicles were traversing a 2- km highway and the following data were take: TIME (min) 1. 8 1.4 1 . 6 1. 5 1 . 3 #) Find the density of traffic in veh/km. Find the space mean speed in kph. Compute the time mean speed in kph....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
