Sometimes adding colour can improve the understanding of technical information. Here are three examples:
The city council’s website (here) gives details of the improvement of the Friedrich Ebert Strasse. The details include a cross-section (image below) as well as contact details, background information on the project, and some “artists impressions” of what it will look like when completed.
Ottawa city council publishes its design and planning guidelines online (see here). The guidelines are worth a visit in themselves. The section on community streetscape guidelines (here) includes an image which combines a cross-section and a plan view, both illustrative and both in colour.

This detailed guideline (it has some 236 pages) includes some innovative quasi 3D graphics such as the one below. I find them particularly good at helping me understand what the guideline is suggesting.
Highway design can be quite a complex technical subject. This can be as true for cross-section information as it can be for longitudinal information. Images can help engineers understand what a designer or a guideline is proposing. And better understanding contributes to better decision-making.
