It seems like ISPs prefer their own or their customer route (which is our transit provider) and there is almost no "short/local route" effect.Correct. That's why you need to use the same transit providers at each location.
It could be a nightmare to try to balance the traffic when you are using different providers. You can go ahead and try using path prepending but you will always find some strangeness going on regardless. As Bill mentioned using the same transit will help, especially if you use a transit provider that has some communities pre-defined which will allow you to automatically advertise or not (even geographically) , and path prepend by simply sending communities out , you will save lots of time.
