I would be sure to keep treats in my pocket and when you see someone coming down the street get her attention and start distracting and treating her. If she's normally good with other dogs it shouldn't be hard to eventually get her to let the neighbors walk by without mass chaos.
If she's a normal 8 month old it should go something like this when you first start.
Distract, treat, distract, treat...distract...opps...lunge...distract, treat.
