Paper Abstract
"For modern automated driving systems, interaction with pedestrians in the mixed traffic conditions is one of the most challenging problems. Potential conflict cases have been widely used to study vehicle-pedestrian encountering scenarios in natural road environment. However, these relatively dangerous cases between human drivers and pedestrians are not necessarily the dangerous cases for automated driving systems, especially when trained artificial intelligence systems can predict the potential risks and prepare in advance. In this study, we investigate the performance of machine learning algorithms in detecting potential conflicts between vehicle and pedestrians, as well as prioritizing passing sequences during the conflicts. A total of five commonly-used machine learning algorithms are tested. The results show that Deep Neural Network can predict the potential risk and passing priority very accurately (93% and 96% respectively) solely based on descriptive scenario variables. A set of wrongly classified cases (False Negative) are also collected for further study which represent unpredictable risks for automated driving systems."
