junction

简述：地图场景为交叉口。lead_vehicle和主车Ego一前一后分别以LeadVehicle_TargetSpeed_Ve0和Ego_TargetSpeed_Ve0的初始速度向交叉口行驶，Ego设定了目标在右转车道上的目标点Target_position，仿真开始后激活Ego控制器（控制器会影响Ego去往Target_position的寻路算法，但目前仿真器B尚不支持寻路动作acquire_position）。另一路段上有一辆车vehicle1，也以LeadVehicle_TargetSpeed_Ve0的速度朝交叉口行驶。控制器有时会根据环境车的位置更改主车Ego的速度。
