Hard braking is considered one of the most highly predictive variables for predicting future crashes. However, normally harsh braking is tied to individual drivers.
This patented composite app has two parts. The front end app is a smartphone app which monitors drivers for harsh braking. When harsh braking occurs, the location is logged. Over time clusters of harsh braking may be observed on the map display, enabling individual drivers to change behavior at those locations. The back end is an anonymous, aggregate view of harsh braking events across the drivers who choose to contribute to the city. A searchable map display of those aggregate events is available to the city traffic engineer. Again, clusters of harsh braking may be observed for their attention, with higher frequency clusters drawing attention of the traffic engineer for possible corrective action.
