您应该注意有关Google Maps API的某些限制. 服务条款，第10.4 c段说:

You should be aware about certain restrictions regarding Google Maps APIs. The Terms of service, paragraph 10.4 c says:

无导航.您不会将服务"或内容"用于(a)实时导航或路线指南；或(b)自动或自主车辆控制.

No navigation. You will not use the Service or Content for or in connection with (a) real-time navigation or route guidance; or (b) automatic or autonomous vehicle control.

因此，您不能将Maps API用于实时应用程序.

So, you cannot use Maps API for real-time applications.
