You have two choices when you need to use a taxi. You can go outdoors in a busy city and wave down a taxi to take you where you want and need to go. Or, you can call on them from their hub.

If you want to be safe, the best thing to do is to call the taxi company directly, ask for a taxi and then wait for it.

If you do approach a taxi by just waving him down, there is no record nor is there any way to know who is actually approaching you. On the other hand, if you were to actually call the station, ask for a cab and then wait for it to come and pick you up, there is now a record of who is picking you up and when.

This may seem to be an inconvenience and a time waster. But, the element of safety is something that you do need to pay close attention to. Realize that you must take whatever precautions are necessary to protect yourself if you are to survive and avoid a negative situation! Inconvenient or not, it is the best way to protect yourself!
