Hello there

I am a university student doing a research on the network of FedEx ground hubs. I dont have experience about how hubs really work and I need some information. I ve found this forum by chance and I hope some of you can help me in my research with your experience .

1. What is operating hour in a FedEx Ground hub? In fact I need to know when the last truck will leave to the next hub.
2. Do hubs receive packages after stopping expedition (for example is it possible that a hub stops shipment at 5 pm but still receives packages till 9 pm or later?)
3. What is the maximum distance that a truck passes from a hub to another? I have limited this distance to 600 km. Is it possible that a driver starts from hub A and drives non-stop to hub B which is further than 600 km?
4. Are the trucks always full?
5. I am assuming each 30 minutes a full truck leaves a hub. Do you think this assumption is lower or above the reality?

I appreciate your help.
Have a great day
