It looks like aggression, but the correct terminology for your dog's behavior is "reactivity".
She is likely either frustrated, or frightened, but if she were truly aggressive, she would behave the same way off lead. This is a handler exacerbated problem - get a copy of "Scaredy Dog -Understanding and Rehabilitating Your Reactive Dog" by Ali Brown. Another good one on the subject is "Feisty Fido" by Patricia McConnell.
