One of the most important and obvious stock and flow is people. everyday people come to the city center and other parts to work, and they leave for home in the evening, which is usually in nearby cities. similar to people, cars can also be modeled in stocks and flows. cars move in and out of the city all the time. another important stock and flow is the water system. every time it rains, the water would be stored in the reservoirs and then gradually extracted for drinking and other purposes. for the flow of people. if it is downtown Los Angeles. it doesn't really have much stock at night since not many people actually live in the city center, but in the morning rush hour, it would have a large flow coming in and it would have a high stock through the day time, but in the evening, people would leave and go home and it would experience a large flow going out. the flow of cars are very similar to that of the people. large number of cars flow into the city center in the morning and park in places so the city center would have high stock during the day, but after the cars quickly flow back in the evening, the city center would have very low stock. in terms of water. whenever there is a rain, there would be a large flow in to the system. and the stock would increase. but when people are extracting water, the stock would gradually go down because of the output. I think in the future, of the pattern of car "stocks and flows" pattern could change, it would change the traffic situation in Los Angeles. Right now, the flow going in to the city in the morning and the flow going out of the city in the evening are too large and too concentrated. in order to reduce the number, the government should think about investing more on public transit. And in order for it to be less concentrated. some companies could maybe slightly adjust their work schedule, so not all the cars and people would rush in and out of the city center at the same time. and I think with both that measures, the traffic problem in Los Angeles could be somewhat alleviated.
