Fragmented connections for SIDEWALK and BIKING lanes #33

Closed CodeMazeSolver closed 1 year ago

CodeMazeSolver commented 1 year ago

Currently, the output CityGML files are missing some successor and predecessor connections. As for the car lanes, the successor and predecessor connections seem to be working fine. However, the lane types SIDEWALK and BIKING suffer from some unset successor and predecessor connections which leads to fragmented networks of those lane types. This is especially significant in intersection areas where many TrafficArea and TrafficSpace objects exist to model the curved street. This can be seen in the following image, showing the TrafficAreas and their TrafficSpace (red) elements.

There might be a way to set the right connections during the converting process. Otherwise, generating the missing connections using only the CityGML data is a tedious task.

Thanks for reporting. The question is whether the original OpenDRIVE dataset contains this connection information or not. Can you provide me with the OpenDRIVE file and another enlarged screenshot to find this exact location? You can send it to me via benedikt.schwab@tum.de.

Thanks for providing the screenshot, @CodeMazeSolver. I double-checked and the TrafficSpaces shown in your image are missing a predecessor or successor relation because they are not connected in the OpenDRIVE dataset.
