For the first trip to school, send her by plane. That way she won’t be juggling her baggage from one means of transport to another. The airline will handle everything except her carry-on(s).
When she’s settled at her university, she’ll be able to learn about other transportation options that are workable. For example, depending on where she needs to get in NY State, she might be able to cobble together cheap travel on Megabus http://us.megabus.com/
