Benefits Assessment of Automatic Brake on Real Pedestrian Collisions

Abstract

This paper describes the main findings of a coordinated study performed by INSIA-UPM aimed to assess the potential influence of several autonomous emergency braking systems (AEB) in vehicle-pedestrian collisions through reconstruction of real-world accidents occurred in the city of Madrid (Spain). A total number of 43 vehicle-pedestrian collisions have been in-depth investigated following a common methodology, including on the spot data collection, analysis and reconstruction to estimate the collision speed and the pedestrian kinematics. Every single case has been virtual simulated six times using PC-Crash® software: the first is a reconstruction of the real accident and the following times are simulations in which the operation of AEB systems are emulated. The AEB systems emulated in this paper through computer simulations are based on commercial solutions.
