This fall I am taking Urban Transportation Systems instead of my originally-scheduled Engineering Accounting.
This course is a special topics survey course that will cover the math of transportation planning, such as roadway capacity, and the practicalities of managing traffic control, such as timing of traffic signals and appropriate speed limits.
I have been assigned an adviser in the Doctor of Engineering in Engineering Management program. He says that I am probably accepted into the program. It sounds like all that remains are procedural issues, mostly paperwork.
