Symbolize multiple attributes on lines
Posted 10 February 2006 - 05:10 PM
It is a supporting figure in a long term road construction plan. For each road, I need to show:
- Surface type (6 different types)
- Traffic volumes counted (4 categories)
- Project priority (2 categories)
I haven't really put a lot of thought into it yet, so far I've tried something like this:
- Roads are symbolized as solid lines determining surface type:
- Traffic volumes shown as a highlight color behind the road, something like:
where the black lines would be the colour indicating surface type.
- Project priority shown as a dashed overlay. Non-priority lines get nothing. Something like:
where the black line would be the colour indication surface type.
It's seems a little busy/confusing. Any suggestions or examples about how to better symbolize something like this?

Martin's system works well, and his last comment about casign colors shouldn't be an issue since you only have 2 priority classes. You should be able to select 2 colors that work with the fill colors and the background.
I think you only need one color for priority. It's binary, so casing = priority is yes, no casing = priorty is no.
