Stopping Distance Calculator app for iPhone and iPad

The application determines the current velocity of the driving vehicle and calculates the required overall stopping distance, that is needed in a hazardous situation and full braking to slow your vehicle down to a complete stop.

The distance your vehicle needs for a full braking driving the current speed to slow down to a complete stop is called overall stopping distance. The overall stopping distance consists of the reaction pathway and brake path. The program uses predefined and rational values for the deceleration and reaction time that may not always be perfectly suitable for the concrete driving situation. Therefore always drive foresighted and with a speed adjusted to the current traffic situation.

The overall stopping distances are usually much higher than most people expect. For example driving 50 km/h the stopping distance amounts to 25-30 m, driving 100 km/h it is already 80 m. These results are valid for a dry and flat road. Downhill the stopping distance increases, uphill it decreases. Wet, snow-covered or icy roadways increase the overall stopping distance drastically. You can adjust the weather conditions in the application during measurement.

Tap the speedometer to change the display from km/h to mph. The distance and elevation data can be converted from metric to imperial unit system by tapping the letter M or the FT at the top of the screen.
