Big data is everywhere. But how can it be used in urban traffic management? Or in traffic information services that can help manage the traffic in a city? This is a rather generic research question that cab be easily divided into smaller questions, such as:
- What kind of big data are we talking about? What would be useful if you want to manage traffic?
- How can big data help us understand and predict when and where traffic management is needed (oversaturated intersections, events, bad weather, severe incidents)?
- What data are available (“open data”) to road authorities, service providers and/or application developers? What data would they have to purchase (and would that be cost effective)?
- What kind of applications/services could be built that offer more than existing applications/services? Or: How could existing applications/services be enhanced with big data?
