CEE 3604: Introduction to Transportation Engineering Fall 2011 Assignment 1: Matlab and Basic Computations Date Due: August 31, 2011 Instructor: Trani Problem 1 One of the basic problems in transportation engineering is determining the performance of vehicles traveling between two points. The flight profiles of three domestic flights in the United States are provided as text files in this assignment. A sample file is shown in Figure 1 for a flight between Dallas and New York. Figure 1. Sample flight profile from Dallas, Texas to New York (Kennedy) airports. Source: www.flightaware.com . a) Import the data (all three flights) using Matlab’s import wizard or sing the Matlab “load” command. b) Create a new Matlab script to do the following: b.1) Create five vectors and label them: time, latitude, longitude, speed and altitude (all 5 columns of the file). These five vectors contain the column data in each file. b.2) Plot time traveled (in x-axis) vs speed (y-axis). Label axes as needed (include units) and change default font sizes to size 16 for both x and y labels. Change the color of the line to solid blue. Comment on the shape of the profile observed. b.5) Plot time traveled (in x-axis) vs altitude (y-axis). Label axes and change default font sizes to size 16 for both x and y labels. Change the color of the line to red. Comment on the shape of the profile observed.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
