- Answers 0: It is a map of all the TT probe points gathered for a particular area with a Tele Atlas map underneath 1: The Tele Atlas Ghent Office area 2: It indicates the nr of community probe points (density) gathered for that spot by the TT devices. (blue: 1 tag, white, 2 or more …. Red : a lot of tags) 3: That’s the location of the TA Ghent office where all employees are using a TT devices ;o) 4: It maybe a boat 5: Just a person activating his TT over there for a short period, it could also be a disrupted signal resulting in scattered points 6: Because people are slowing down there for the roundabout, as such the devices will create more probe points at that spot 7: It also indicates the accuracy of the probe points 8: There is a traffic light there, so people stop a lot at that location 9: The probe points are also attributed with height information, so we can derive Z-level info from them 10: A TT device continues to route in a tunnel with the help of gyro’s & speed estimation so it can also continue create probe points 11: We can determine speed out of probe this combined with travel behavior, used road types and other meta data (if needed), we can figure out a range of vehicle types and enrich our maps 12: The probe points are attributed to which sequence they belong (a probe trace), they also contain an accuracy indication. The probe traces with acceptable accurate probe points are filtered out, then the average trace is calculated out of the resulting bundle of probe traces enabling us to form a nice network.
