This schematic shows the speed zones on the rail network, which infrastructure workers need to access the rail network safely. Since most of the work is done outside peak hours, the schematic must be readable under low light conditions.
The original speed zone map was out-of-date. Infrastructure workers couldn't legally access the train network without accurate, up-to-date information. In the original speed zone map, there were more than 12 colours, which is beyond the ability of most people to distinguish. There was also no easy way to update the artwork files.
We designed a visual language that would work in low light conditions and be readable by people with any degree of colour blindness.
And we ensured that Metro Trains Melbourne could maintain the files themselves using AutoCAD by constructing the file so it could be translated into AutoCAD from Illustrator and back out again.
Our technical solution was to construct the artwork files so that they could move between Illustrator and AutoCAD without any degradation of line formats or file structure.
In addition, the schematic had to be split into line sections and maintain the same information, both visually and encoded in the artwork files.
Expert knowledge of Illustrator, file formats and AutoCAD was required.
