Transportation Symbology

MaryM — Mon, 09 Apr 2012 16:09:47 GMT

I have a dataset of am and pm road links. By road links I mean lines that are individual objects with an A and B node like this road line is point a to point b, the next line is point b to point c. Then, the nodes reverse for pm and go c to b, b to a and etc... I need to have them show up offset from their locations due to at the map scale I need they show up one on top of the other. They do not have a shared attribute like road name to connect them. How can I get them to represent themselves apart from each other? I do not have a matching road layer to the location of these road lines as the road lines I am using are an output of a travel model that are off from the actual road, I have nothing connecting the actual road to the travel model. I am aware of the dissconnect issues with the travel model company and am dealing with those. I have network analyst extension available if I need that. I am looking for a simple solution because it is purely a display issue at this point.

What license level are you using? If you have ArcEditor or ArcInfo, you can look into using representations. They are a way of symbolizing data like applying a buffer or offset without actually changing the geometry of the data. Specifically, look into the Move or Offset effects.

The issue is I do not have them labeled to all be of the same line. I could use an offset but the issue is I could have all am and pm offset in the same direction or just offset the am but I am not sure which is which. I want to I guess add an attribute so that a to b and b to c all have a similar attribute. There are nodes that have an identifier which is a unique number that is what a or b or c is. I need a way to link the lines together like a is going to b line and b is going to c line have to be put together somehow. I have a series of lines with to/from but no route, I guess I need a route made.
