Developed by Nokia, Here.com features a traffic view section that allows users to check the latest road conditions. The app uses road sign icons to indicate road closures or construction on various interstate highways, indicating heavy traffic spots by laying in red and yellow markers. Here.com also allows offline navigation by providing downloadable maps of specific cities and states.

The state of California features a dedicated QuickMap Web page and mobile app to present real-time traffic information. Unlike Here.com, which uses a personal map, Caltrans QuickMap uses layers on a Google Map, allowing for easy interface navigation for people familiar with Google's mapping platform. The Web page and app use real-time information from the California Highway Patrol and include active feeds and messages.

Like the Caltrans QuickMap, SigAlert presents detailed and up-to-date traffic information. It shows a color-coded map indicating a slow, medium or heavy traffic buildup along highways and avenues. The camera icons show still images on various locations across the selected city. Unlike QuickMap, SigAlert has limited zooming in and panning around options and may be more effective when used as a quick reference for longer routes.
