What new technologies will dramatically transform your world? We’ll present an exclusive preview of the stunning breakthroughs emerging from the world’s leading research labs. 

The ultimate goal when developing software for Level Five autonomous automobiles is to ensure that they will not cause accidents. New software developed at the Technical University of Munich prevents accidents by predicting different variants of a traffic situation every millisecond.

A car approaches an intersection. Another vehicle pulls out of the cross street, but it is not yet clear whether it will turn right or left. At the same time, a pedestrian step into the lane directly in front of the car, and there is a cyclist on the other side of the street. In these situations, humans with road traffic experience can generally assess the movements of other traffic participants correctly.

However, these kinds of situations present an enormous challenge for autonomous vehicles controlled by computer programs. 

According to the journal Nature Machine Intelligence, researchers at the Technical University of Munich have now developed a software module that continuously analyzes and predicts events while driving. To do so, vehicle sensor data are recorded and evaluated every millisecond. The software can calculate all possible movements for every traffic participant — provided they adhere to the road traffic regulations; this allows the system to look three to six seconds into the future.

Based on these future scenarios, the system determines a variety of movement options for the vehicle. At the same time, the program calculates potential emergency maneuvers in which the vehicle can be moved out of harm’s way by accelerating or braking without endangering others. The autonomous vehicle may only follow routes that are free of foreseeable collisions and for which an emergency maneuver option has been identified.

This kind of detailed traffic situation forecasting was previously considered too time-consuming and thus impractical. But now, the Munich research team has shown not only the theoretical viability of real-time data analysis with simultaneous simulation of future traffic events; they have also demonstrated that it...
