CE592 Homework Assignment One Please complete the following and submit your solution at the start of class on the due date. You may submit a hard copy in class or a digital copy (in Blackboard). Part A: Critical Movement Analysis 1. For the following intersection, assume a two phase operation (N-S is one phase and E-W is a second phase) and use the saturation flows from class. The sketch shows volumes for the peak hour. What is the critical v/s for each movement. 2. Which v/s values are critical for each phase? 753 1251 11 526 1489 Part B: Turn Lanes Review the DOT Bureau of Local Roads and Streets regarding the design of an intersection turn lane. Assume the left turn movement is provided 12 seconds of green time for a DHV of 210 vehicles per hour, in one turn lane. The overaill intersection has a 90 second cycle length, 3% trucks, level grade, and no offset of the centerline 1. What storage length do you recommend for the left turn lane? 2. What taper length do you recommend for the left turn lane? Part C: Terminology This semester, you will learn many new terms. Reinforce your learning of the common signal terms by creating a puzzle or game that uses 10 of the terms from class. For example, you could create a crossword puzzle or word search. Be creative and have fun. CE592 Homework Assignment One Please complete the following and submit your solution at the start of class on the due date.
