Nokia seem to be getting into navigation in a serious way these days. First they bought the software company Gate5 and produced Nokia Maps, then last year they bought their own mapping company: Navteq, now they are moving into the traffic business...
Nokia Community Enhanced Traffic is not a term we were familiar with before we arrived on the Nokia booth at CES this year. We approached Quinn Jacobson a research leader at the Nokia Research Center for an explanation. Basically Nokia use the phone as a probe and aggregate the information the users pass to the server with other traffic information (specifically Navteq) to provide an enhanced view of traffic that can then be displayed on the user's device. Although this mechanism can collate masses of data there are a number of pitfalls to community based collection we put some of these to Quinn to find out how Nokia overcome them.
