I am not sure if this answer will be helpful or not.
In Texas, there are a number of research efforts underway to understand how autonomous vehicles will change the way in which highway transportation systems will function in the future. This includes how vehicles will communicate with each other; how vehicles will communicate with transportation infrastructure and what steps transportation engineers should be taking now and how they should be preparing for a future in which vehicles will drive themselves.
Several US states are studying this issue from a legal and engineering perspective and transportation engineers are required to expand their expertise into new technical areas that will be integrated in future transportation networks.
As a start, perhaps you can search the University of Texas at Austin - Center for Transportation Research (CTR) online library - we maintain this library for the Texas Department of Transportation and for use by the research community.
i would suggest typing 'autonomous vehicle' in the key word search field and you will find several studies and white papers that are just now publishing what we think the impacts of autonomous vehicles will be in terms of future engineering technical training, ability to communicate with experts in several new fields, development of new technologies etc etc.
As an example, I recently viewed a presentation at a symposium held at the University of Texas which showed a simulation of a future highway intersection which had no traffic signals. Each vehicle communicated with every other vehicle to determine speed, location and distance such that adequate gaps were allowed for continuous flow of vehicles through the intersection thus improving operations. However, how will pedestrians cross such an intersection? There are also many questions about security related to these future technologies.........
