而由于真实模拟无法多次重现，因此对于不同的应用场景，又往往需要重新部署

However, since the real simulation cannot be reproduced many times, it is often necessary to redeploy for different application scenarios, and the cost is high. Moreover, it is difficult to simulate traffic accidents in the simulation of the real traffic environment.

Because real-world simulations cannot be reproduced multiple times, they often need to be redeployed and costly for different scenarios. And the simulation of the real traffic environment, it is difficult to realize the simulation of traffic accidents this kind of scene.
