A woman I know unnecessarily avoids me

A woman who was in my dance class for two years sits in the same commuter train car that I do. When the train arrives, she does everything she can possibly do to avoid greeting me (looks down in her lap, looks out the window, waits to get up until I have left the train). It's obvious that the is avoiding me; she works in the office building next to mine, and a few times over the past years we've walked from the station to our office buildings together.... I guess a few too many times for her!

I don't want a daily walking buddy, and I enjoy the morning walk alone as well. It makes me uncomfortable that she's obviously avoiding me. What can I say to her to let her know it's OK, that she needn't avoid me and that I get the hint?
