Python怎么用traci获得Sumo 一辆车什么时候进入和离开路网

Python可以使用traci库的函数来获得Sumo中一辆车什么时候进入和离开路网。具体来说，可以使用以下代码：

import traci

# Connect to SUMO
traci.start(['sumo', '-c', 'path/to/your/sumo/config/file'])

# Get the list of vehicles
vehicles = traci.vehicle.getIDList()

# Get the entry and exit times for each vehicle
for vehicle in vehicles:
    # Get the entry time
    entry_time = traci.vehicle.getSubscriptionResults(vehicle)[traci.constants.VAR_ENTRY_TIME]
    # Get the exit time
    exit_time = traci.vehicle.getSubscriptionResults(vehicle)[traci.constants.VAR_LEAVE_TIME]
    print(f"{vehicle} entered at {entry_time} and left at {exit_time}")

# Disconnect from SUMO
traci.close()

此代码可以列出Sumo中每个车辆的进入和离开时间。请注意，在使用这个代码之前，需要先安装Sumo和traci库。
