Traffic Heatmap Service

Our Heatmap application aggregates GPS signals send by taxi cabs in the city of Dresden in a rectagular grid. The user can choose between displaying an aggregation of the number of signals and the average speed with different at different scale. The application should help drivers and companies to plan their daily trips by providing an interactive web map visualization which is easy to read and to use. Within the ExCELL project we will extend this solution to a web service where a user can create his own heatmaps selecting different data sources, hot spot analysis methods and display forms. Computation is done by Apache Spark and Apache Impala.


Route Blocker

Dresden Route Blocker is a web map application to demonstrate which alternative routes taxi cabs would take in case of sudden block events on certain streets. The data represents historic Floating Car Data (FCD) from a taxi company of Dresden. The origin and destination of single trips were used to feed a routing engine (Graphhopper). The retrieved track is animated using the D3.js library. If a user clicks into the map a route blocking service from the ExCELL plattform is called which also triggers a rerouting of all currently running trips. If a road intersects a route of a taxi, the user will see, that the car will take another way to drive around the blocked network element.

With this interactive component the user understands, how the ExCELL plattform enables for smart mobility and transportation management in real-time.
