Hi

I am in need of some assistance. I have a traffic link network,
composed of a polylines.

I want to identify all the links within 200m of a location. I then
need to know, for each identified link, if it is connected to any of
the other links identified. Ideally, i need this to be automated
because i need to repeat the process for many thousands of locations,
and the output added to a field(s) associated with each location.

For example, in the diagram below assuming all these links are within
200m i need a list which shows that:

1 is connected to 2 & 3
2 is connected to 1, 3 & 4
3 is connected to 2 & 4
4 is connected to 2 & 3
5 is connected to 1 & 2

3/

----------/ \4

\5

All help much appreciated!

Thanks

I have noticed an error in the diagram it should be:
>
> 1 is connected to 2 & 5
> 2 is connected to 1, 3 & 5
