使用队列来模拟停车场和便道上的车辆，每一次进出车辆都需要对队列进行操作。

好的，以下是一个基本的停车场和便道队列模拟程序：

class ParkingLot:
    def __init__(self, capacity):
        self.capacity = capacity
        self.parking_lot = []
        self.waiting_queue = []

    def park(self, car):
        if len(self.parking_lot) < self.capacity:
            self.parking_lot.append(car)
            print(f"{car} has parked in the parking lot.")
        else:
            self.waiting_queue.append(car)
            print(f"{car} is waiting in the queue.")

    def leave(self, car):
        if car in self.parking_lot:
            self.parking_lot.remove(car)
            print(f"{car} has left the parking lot.")
        elif car in self.waiting_queue:
            self.waiting_queue.remove(car)
            print(f"{car} has left the waiting queue.")
        else:
            print(f"{car} is not found in the parking lot or the waiting queue.")

    def status(self):
        print(f"Parking lot capacity: {self.capacity}")
        print(f"Number of cars parked: {len(self.parking_lot)}")
        print(f"Number of cars waiting in the queue: {len(self.waiting_queue)}")

    def display(self):
        print("Cars parked in the parking lot:")
        print(self.parking_lot)
        print("Cars waiting in the queue:")
        print(self.waiting_queue)

这个程序使用了一个 `ParkingLot` 类来表示停车场，其属性包括停车场的容量、停在停车场上的车辆列表以及等待队列。类中定义了 `park`、`leave`、`status` 和 `display` 方法来模拟进出车辆、查询状态以及展示当前停车场和便道的车辆情况。

以下是一个简单的测试：

parking_lot = ParkingLot(2)
parking_lot.status()
parking_lot.park("car1")
parking_lot.park("car2")
parking_lot.park("car3")
parking_lot.status()
parking_lot.leave("car2")
parking_lot.status()
parking_lot.display()

输出：

Parking lot capacity: 2
Number of cars parked: 0
Number of cars waiting in the queue: 0
car1 has parked in the parking lot.
car2 has parked in the parking lot.
car3 is waiting in the queue.
Parking lot capacity: 2
Number of cars parked: 2
Number of cars waiting in the queue: 1
car2 has left the parking lot.
Parking lot capacity: 2
Number of cars parked: 1
Number of cars waiting in the queue: 1
Cars parked in the parking lot:
['car1']
Cars waiting in the queue:
['car3']

在这个测试中，我们首先创建了一个停车场，容量为 2。接着我们查询了停车场的状态，此时停车场为空。然后我们依次让三辆车进入停车场，其中前两辆车可以直接停在停车场上，而第三辆车需要等待在便道上。接着我们让第二辆车离开了停车场，此时停车场中只有一辆车，便道上还有一辆车。最后我们展示了当前停车场和便道上的车辆情况。
