Course Philosophy and Structure: Course Objectives: During each session (week) I will assign work to be done. I strongly believe that one learns more from reading and discussing with your colleagues than from listening. The work may take the form of problem sets, readings, or small projects. Class participation is essential for course. In addition, I will ask each student to prepare a term paper on a specific topic in traffic safety. The paper will deal with a specific problem statement in traffic safety. At the end of the course, each student will present the results of their research/term paper. Additional information will be provided at the beginning of the class.

Students are expected to understand and abide by the Aggie Honor Code presented on the web at: No form of scholastic misconduct will be tolerated. Academic misconduct includes cheating, fabrication, falsification, multiple submissions, plagiarism, complicity, etc. These are more fully defined in the above web site. Violations will be handled in

7 accordance with the Aggie Honor System Process described on the web site. Exam Policy: Communication via (questions on homework, exams, class examples, etc.) is encouraged. As much as possible, questions submitted via will be answered to the sender as soon as possible. The instructor will use the system to make any relevant notifications. s may also be used to distribute clarifications on class lectures, homework, exams and problem solutions. Use of is strictly voluntary. If you would like to receive course-related , send the instructor an message, indicating your name, the course, the section, and your e- mail address. Per student rules, if you have 3 scheduled final exams on the same day you may request that one of your exams be moved. You can find the procedure information here: Departmental policy is that when the middle exam is for a civil engineering course, that exam will be moved to a time agreed upon with the course instructor. If that middle exam is for this course, please let me know as soon as possible. Note that you must complete the process in the link above, including getting the form signed by the dean s office, no later than 10 working days prior to the start of final exams. ADA Policy: The Americans with Disabilities Act (ADA) is a federal antidiscrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact the Department of student Life, Services for Students with Disabilities in Room B118 of the Cain Hall Building, or call Prepared by: Dominique Lord Date of Preparation: Aug. 20, 2018
