Systematic Mapping Study on Autonomous Vehicles

• Collaboration with Hang Yin

• First step of extracting publications containing “autonomous” AND “vehicles” as well as synonyms

• Found > 18.000 publications

• Current: – Filtering for relevant papers– Extract topics, research methods, and approaches– Present the “research map” on autonomous vehicles

16

Next Steps

• Focus groups with industrial (project) partners

• Systematic mapping study on the state-of-the-art in science

• Interviews/survey with international collaborators– 1 hour (Skype) interview
