How to solve the "last mile" problem in traffic

I am currently working on an innovation research project on how to solve the so called "last mile" issue in traffic at the Vienna University of Business and Economics. The "last mile" issue is the fact that it's often difficult and inconvenient to get from the public transport station to your home or office without using a private car.

I'd really like to hear your opinion about the topic. What could be a good solution? Do you know a person who is very active in that field and maybe has already developed some technical solutions or interesting concepts?

I'm looking forward to your replies.

Thanks and best wishes from Vienna!
