A grade of B or better must be achieved for the dissertation.
3. Completion of two minor areas of study, each consisting of between 9 and 12 units of graduate work. At least one minor area must be outside the transportation area.
4. Residency requirements for the Ph.D. (Transportation Planning and Engineering) include the 30-unit dissertation plus a minimum of 12 units of applicable graduate course work taken at the Polytechnic.
5. In satisfying the 60-unit course requirement, the student must satisfy all requirements for the major and minor areas selected, or their equivalent.

1. 48 units of appropriate graduate course work, not including individual guided studies (readings, projects, theses, etc.) beyond the bachelor’s degree, with an average grade of B or better (cumulative average of 3.0 or better on a 0-4 scale).
2. 24 units of appropriate graduate course work, not including individual guided studies (readings, projects, theses, etc.) beyond the master’s degree, with an average grade of B or better (cumulative average of 3.0 or better on a 0-4 scale).

Satisfying condition 2 requires that the department accept the student’s M.S. degree in toto without regard to its specific content. This requires a recommendation from the department’s Graduate Committee, and the approval of the department head.
