Highway Radar is an application to help drivers be aware of road hazards, cameras, and speed traps. It collects traffic-related information from multiple sources and provides notices on potential risks on the road. Crowd-sourced alerts: Highway Radar can connect to a sever aggregating crowd-sourced alerts and show them on the map. It also issues audible voice warnings and optionally a beeper to grab the attention. Currently, the application supports alerting on speed traps and road hazards reports. Aircraft alerts: In some countries, aircraft traffic enforcement is in use. Highway Radar collects information about air traffic around though various ADS-B exchange sites (ADSBx, OpenSky). Then it matches every aircraft to multiple registration databases and alerts drivers only on those which can potentially do traffic enforcement. Historical data analysis: Highway Radar aggregates data about past police and speed trap reports and estimates the risk of a given area being heavily patrolled. The app also features a heat map that shows places with especially frequent speed trap reports. Speed and red-light cameras: Highway Radar can warn the driver when approaching a traffic camera. This feature is available in the USA and Canada only. Extra features: Highway Radar can also show you traffic jams on nearby streets and a weather radar information around you.
