Highway Radar

About this app

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.

NOTE: This application can use accessibility service to launch other application on service start, including activating split-screen mode or preloading the application. The accessibility service isn't used for anything else but launching other applications upon service start, and only if Highway Radar is configured to do so. No data is accessed, collected, or shared in any way though the accessibility service.

Ratings and reviews

It worked great on my drive from SC to Florida. I was able to get advanced warnings of police the whole time. I would get an alert when the police were 3.5 miles away. Using it for normal driving at home doesn't work because it alerts for police in the vicinity, but no where I'm going. Overall, it works great for the highway. Please read the instructions before giving up. I followed the instructions and it worked great.

The Gold Standard in App development. I have used this for a while, but using it on a road trip now, I've had time to think and appreciate this app for what it is. It's exactly what you want, exactly when you need it, all the features you need, VERY well executed controls, which is very important for an app that might get used while driving. More specifically, it's got traffic density, cop density, weather, speed limits, *aircraft, helpful audio alerts, and all the settings you could ever want.

The app is pretty great, I don't think I've drove without it in the past year. Even if you're not using it to avoid speed traps, being alerted about cars on the side of the road, potholes, roadkill, etc is very useful and has allowed me to prepare so I didn't have to take emergency action to avoid hitting obstacles a number of times. My only complaint is how the app really wants to rotate to portrait mode more than any other app I have, I have yet to figure out why this happens.

What's new

Reduced internet traffic usage for aircraft alerts by 30-40%.
