4Warning is a location-based app service that allows anyone who has downloaded this application to alert other members within a 1/2 mile radius of live hazards or disruptions when commuting around our cities and roads For example, if a 4Warning member(John Smith for example) observes a road accident that is causing built-up traffic he simply open the app and selects the road accident icon, and press enter. 4Warning then simply alerts all other members within 1/2mile of John’s position with a live map showing the road accident icon and additional information (text, video, photo, or voice message). This allows members the opportunity to avoid the area and delays. Drivers in the UK spend on average 115 hours per year in traffic jams. 4Warning was developed to help drivers avoiding unnecessary delays and costly disruptions to their daily commute.
