Question show all steps please :) The following spot speeds were measured in mi/hr at a location along a two-lane highway (for one direction only), over a period of 1 minutes. 69 54 67 69 58 62 57 61 63 58 Calculate the following traffic stream parameters a) time mean speed b) hourly flow rate c) density, if the space mean speed (assume that all vehicles were traveling at a constant speed) is 60.04 mi/hr. The following volume counts were taken on an intersection approach during the morning peak hour: Time Period 8:00 - 8:15 AM 8:15 - 8:30 AM 8:30 - 8:45 AM 8:45 - 9:00 AM Volume (vehicles) 150 155 165 160 Determine: (a) the hourly volume, (b) the peak 15-minute flow rate, and (c) the peak hour factor (PHF).
