If you make eye contact multiple times and he looks away quickly, he is most likely checking you out, but is shy about it. Therefore, he probably won't approach you, as some of us are just as shy as you. You'll have to make the move if you want to meet him.
Smile a little bit and see if he smiles back! If he's shy, he might look away when you do this initially, but if he makes an effort to make look back again and smile at you, there's a fair chance he likes you.
