How to find a closest street

Question

Hi,

I'm reading through Google Maps API documentation and I wonder if such a think is possible:

1. I specify the point (by coords)
2. I search for all roads, and junctions around the node (say in 1km radius)
3. I get parameters for the streets around (polyline coords)

Is it reachable, or google do not share that data?

Thanks in advance Rafal
