We are looking for an icon collection for a traffic reporting application. Special situations or occurances should be visualized with an icon. Most of these icons go along with text, the simpler ones have to stand on their own. There are no graphical constraints, the icons should be understandable on first sight, they should adhere to the "form follows function" principle. Color should be used for differentiation and to clarify as necessary. We need 35 different icons, see list URL at bottom.
The icons are used by the application in 24bit PNG file format. The icons are used on white, blue and dark grey background color. Transparency should be used for smooth edges.
The icons appear in the application in two sizes: 28*28px and 40*40px. Be prepared to submit original files in bigger sizes to be able to render the icons to other sizes as well.
For submission you may arrange the icons in 28px and 40px size on one background to show all of them at once.
LIST OF ICONS NEEDED
HOW TO SUBMIT
The collection of icons should be prepared to be sent in as a ZIP file composed of three files per icon. The names of the files should comply to this naming rule: icon_name_28.png for 28px size, icon_name_40.png for 40px size and icon_name_source.psd or icon_name_source.ai for the source file. Please do not use any stock images or clip art.
