How can I create "buffers" or vector from values from a layer of points, where the "buffers" are "tied" to the streets?

Example: A bus station, I would like to create vectors within 100 m range with streets, from the point, regardless of the direction, following the road system.

I need to make a linear "buffer", following the system road, to identify the distance the bus station will cover on every street.

You still need to create an AFTER image. Words are not going to suffice – Vince Feb 04 '16 at 17:30
