Ballbank is a meticulously designed digital inclinometer that aims to improve roadway safety by providing accurate advisory speeds for horizontal roadway curves. Developed by Christopher Dry, this utility tool is available for free on the iPhone platform.

With Ballbank, determining advisory speeds becomes a breeze. By measuring the combined effect of superelevation, vehicle roll, and lateral acceleration in degrees, this app allows engineers to assess driver discomfort and set appropriate advisory speeds.

Setting up Ballbank is simple. Just place your phone on the dashboard like a traditional ball bank device and press Start. The app records all the necessary data, saving it as a video directly to the Photos app. Additionally, a text file containing all the curve data results can be exported and emailed.

One of the standout features of Ballbank is its ability to provide comprehensive insights. In addition to displaying continuous angle readings and speed, the app calculates the maximum smooth angle, average speed, and lateral g force for every curve. It also records linear distance, latitude/longitude, altitude, date, and time, making it easy to analyze and visualize the collected data on a map.

Furthermore, Ballbank allows you to evaluate driver performance, document existing signs, assess site safety, and verify pavement conditions. By recording the video of your drive, you can thoroughly analyze various factors that may impact testing results.

Whether you prefer Imperial or Metric units, Ballbank has got you covered. It supports both unit systems, ensuring compatibility with engineers worldwide.

With its precision, ease of use, and beautiful design, Ballbank is an invaluable tool for engineers and professionals involved in roadway safety. By providing accurate advisory speeds, it helps enhance driver comfort and ultimately contributes to safer roadways.
