Understanding Real-Time Trajectory

We've added a real-time trajectory tool to Compass Road Intelligence. Select any long arterial section of road to get real-time trip data.

We've added a real-time trajectory tool to Compass Road Intelligence. You can find Real-Time Trajectory data under the new Trajectory Tool. The tool works best for long selections on divided and/or large arterial roads.

As vehicles travel down the selected path, they leave traces in real-time, represented by the solid lines. Historical trajectory data is also presented on the graph, in the form of dotted lines. These help identify historical traffic conditions for the selection based on data from one week before the date you view. This is labelled 'Control Data' in the left-hand corner of the results panel; this date cannot be changed in the first release. 

The black vertical line is the actual time of day that the user is viewing the data. This line will move and trips will appear as real-time data renders on the graph. 

Below is an example of historical data (faded dotted lines representing data from the week prior) and real-time data (solid lines). Sometimes, a gap will appear between the real-time trip lines and the black line indicating the current time. This indicates the delay in real-time data updating on the front end.

By default, the platform selects the posted speed limit as 100km/h. You can adjust this based on the road you have selected as vehicle speed is colour-coded relative to the speed limit. Red and orange are when vehicles are going slower and where queues are likely to be forming. 

Real-time can only support one path selection at a time.
