Some question about frenet optimal plan #15

Closed AntaiXie closed 5 months ago

AntaiXie commented 7 months ago

Hello, if the USE.DECISION-MAKER in the config file is False, the generated trajectory will not change lanes? Because I found that if the vehicle behavior is not changed, it is always KL, so the trajectory for keeping the lane will be generated by "def lanekeeping_trajectory_generator"

The parameter USE_DECISION_MAKER specifies whether or not to use the decision module in the simulation. When USE_DECISION_MAKER is False, vehicles can still change lanes.

Vehicle's behavior is maintained through a state machine. In line 136 of the file trafficManager/traffic_manager.py, the vehicle state machine can be updated by the function vehicle.update_behaviour(roadgraph, KEY_INPUT), which ensures that the vehicle follows the given route.

If you need to get more information about the decision module, you can check out Decision-making in Part B of Section IV in the paper.
