RCV app

Updating interface for app that controls road signs.

Day mode

Night mode


Because the app is used at the side of motorways in all weathers it needed to be usable in all visibilities.


The app needed to be easy to use and simple to access whilst roadside.


The app fits in with Costain’s branding.


This app was designed to take advantage of colour contrast, to improve its accessibility.

The day/night mode switch at the top is a nice touch to improve usability.
