Hi,
Please refer to the following code to create a junction in RoadRunner HDMaP using MATLAB:
% Create a new junction
junction1 = roadrunner.hdmap.Junction;
% Define the connections for the junction
connection1 = roadrunner.hdmap.Connection('RoadSegment1', 'End', 'RoadSegment2', 'Start');
connection2 = roadrunner.hdmap.Connection('RoadSegment2', 'End', 'RoadSegment3', 'Start');
% Add the connections to the junction
addConnection(junction1, connection1);
addConnection(junction1, connection2);
% Add the junction to the HDMap
hdMap = roadrunner.hdmap.HDMap;
addJunction(hdMap, junction1);
In this example, we first create a new junction object using the ‘roadrunner.hdmap.Junctionconstructor. We then define two connections that connect three road segments (‘RoadSegment1’, ‘RoadSegment2’, and ‘RoadSegment3’). We add these connections to the junction using the ‘addConnection method. Finally, we add the junction to the HDMap using the ‘addJunction method.
You can refer to the following documentation:

Thank you for your answer, but there is something wrong when I run these...
% Create a new junction
junction1 = roadrunner.hdmap.Junction;
% Define the connections for the junction
connection1 = roadrunner.hdmap.Connection('RoadSegment1', 'End', 'RoadSegment2', 'Start');
The class roadrunner has no Constant property or Static method named 'hdmap'.
It says The class roadrunner has no Constant property or Static method named 'hdmap'.
And I also can't find the document of 'roadrunner.hdmap.Connection'. Is there really exists Connection objects?
