“GetLaneInfoByS: No connecting lane” issue with pedestrian models

[Abhiram-R]

Hi,
I’m using the map “fabriksgatan.xodr”. I simply added a pedestrian using lanePosition in road 2, lane -3 and s 295. (default orientation) and ran the xosc file.

The pedestrian follows the road in the order 2->16->3. But the simulator does not seem to find the connecting lane properly. Therefore the pedestrian instantly gets positioned into the nearest “driving” lane. How can I fix this?

Last default value of function parameter int laneTypeMask = Lane::LaneType::LANE_TYPE_ANY_DRIVING
Try to solve the problem？
laneTypeMask =Lane::LaneType::LANE_TYPE_ANY

Hi. Based on what I understood, I changed the laneTypeMask = Lane::LaneType::LANE_TYPE_ANY_DRIVING in RoadManager.hpp to laneTypeMask =Lane::LaneType::LANE_TYPE_ANY and rebuilt the package (xcode). However, the issue is still present. Is this the right way to do this or have I missed anything before build?

The default parameters of the repair header file are useless
You need to call the SetSnapLaneTypes function before calling the GetLaneInfoByS function
If the problem has not been solved, you need to share a simple XODR file for the author to analyze the problem

I have made changes to SetSnapLaneTypes to consider LANE_TYPE_ANY only when the object type is a pedestrian, else take it as LANE_TYPE_ANY_DRIVING. It seems to be working now.

Thanks for reporting this limitation. I see you found a way.

I think this is an important use case so I've changed the behavior so that pedestrians will by default snap to sidewalks as well.

In addition I made road sensors active and visible for pedestrians as well.

Please pull latest from master and try out.

You can try attached scenario file: walk.xosc.txt
Control pedestrian with keyboard (arrow keys)

Run as: ./bin/esmini --window 60 60 800 400 --osc ./resources/tmp/walk.xosc --road_features on

Yes, it is working fine now. Thank you for fixing this.
