Can autonomous vehicles improve the world's largest human migration?

Not many people know that the Chinese New Year is responsible for the largest annual human migration in the world. It even has its own name - Chunyun.

As city workers head out to the suburbs or rural areas, or travel across the country to their home town to spend time with family, train lines, airports and road systems see over 380 million people undertake some sort of journey in China. Thanks to a lack of affordable plane and train tickets at this time of year, these journeys are often done by car, with long drives cheaper than short flights. So could autonomous vehicles help to reduce the strain on road networks caused by Chunyun?
