I found that in SUMO, once traci.vehicle.changeLane(“self_car”, “{}”.format(0), 5) be started, it will not accept new action during the 5 steps, For example, if I want to abort the lane change in this whole duration, what should i do? Here’s my code, since it’s no use:

def abort_lane_change(egoID, original_lane_index):
    traci.vehicle.changeLane(egoID, original_lane_index, 0) 
    print(f"Vehicle {egoID} aborting lane change and returning to lane {original_lane_index}")


for step in range(duration):
    time.sleep(0.5)
    traci.vehicle.setLaneChangeMode("self_car", 0b000000000000)
    traci.vehicle.setLaneChangeMode("vehicle1", 0b000000000000)
    traci.vehicle.setSpeedMode("self_car", 0)
    traci.vehicle.setSpeedMode("vehicle1", 0)
    traci.simulationStep()

    if step == 10:  # 假设在第10步开始换道
        traci.vehicle.changeLane(egoID, 1, 5)  # 换到车道1，用时5秒

    if 10 < step < 15:  # 在10到15步之间尝试中止换道
        current_lane_index = traci.vehicle.getLaneIndex(egoID)
        print(f"Step {step}: Current lane index of {egoID} is {current_lane_index}")
        if current_lane_index != original_lane_index:
            abort_lane_change(egoID, original_lane_index)

I will really be appreciated if any one can help me with this problem.
