Traffic light related stop_line are generated in incorrect positions

[meua]

Excuse me, the stop line is in the wrong place, and the generated map file is missing lane_overlap_info.start_s and lane_overlap_info.end_s
The position of the stop_line is offset as follow:

The position of the decision fence is shifted as follow:

What do you mean by the stop line error, the stop line is about 1m behind the zebra crossing. I don't understand what is the error？

I saw in the picture that the stop line ran to the sidewalk. I don’t know if I understand it correctly. as shown in the green box：

Also stop_line of some lane are missing. The following figure is Town01.xodr rendered by carla (carla 0.9.14 comes with a map)：

Thank you very much for your support. Traffic light related stop_line are generated in correct positions. This is a very nice function implementation. The stop line is still a little flawed. Some stop lines are not generated as expected, I will continue to try to locate and fix this problem, thank you very much. as shown in the green box in the following figure, :

The actual position in carla is as follows:

The example is in the area shown in the green box below in the Town01.xodr map:

Looks like only one side is missing. This is because the right side of the road is the last section, while the left side is the first, and only the right side added.

I updated the code, but I'm not sure if the traffic lights are connected correctly, at least the stop line should be displayed normally now.

OK, pretty cool. I'll run again tomorrow and have a look. Thank you so much.

@daohu527 Excuse me, the code submitted at the end seems to have some minor logic problems, I try to adjust this part normally.

[daohu527]

I know the problem, will fixed soon

Great, looking forward to seeing your fix.

Updated, but I'm not so sure about traffic lights overlaps

Okay, thank you for reminding, the current implementation is to process the traffic lights on the left and right sides separately. Is it necessary to calculate the is_merge field for lane overlap?

Updated, but I'm not so sure about traffic lights overlaps

The stop line is still flawed.
