Example of Raw Data:
Algorithm Slideshow:
1. Initialize Lanes
The Lanes are accessed from the Database.
2. Create a Geofence
3. Geofence GPS-Points
Points used for Geofence creation.
4. Create GPS-Trajectories from Points
5. Lane End Points
Find the points of the lanes, which intersect with the geofence.
6. Lane End Point Buffer
Create a Buffer around each Lane end point.
7. Exit/Entry
Classify the Lane End points in Exit or Entry Point.
Lane Buffer Methods Slideshow:
1. Fixed Buffer Method
4 different Buffer Radii are taken, depending on the amount of neighbouring points.
2. Variable Buffer Method
The Buffer Radius is calculated for every lane end point. The 'Odd Number' variable defines the distance, where an odd amount of link points is found. If the distance exceeds the 'Maximum Point Distance', the algorithm fails.
3. Long Buffer Method
The Buffer is longitudinal, whereas the buffersize variable defines half the length of the buffer. The width of the buffers is set to the minimum distance of all lane endpoints to each other.
