Pedestrian Behavior Prediction Using Machine Learning Methods
Doktorsavhandling, 2024
Background: Accurate pedestrian behavior prediction is essential for reducing fatalities from pedestrian-vehicle collisions. Machine learning can support automated vehicles to better understand pedestrian behavior in complex scenarios.
Objectives: This thesis aims to predict pedestrian behavior using machine learning, focusing on trajectory prediction, crossing intention prediction, and model transferability.
Methods: We identified research gaps by reviewing the literature on pedestrian behavior prediction. To address these gaps, we proposed deep learning models for pedestrian trajectory prediction using real-world data, considering social and pedestrian-vehicle interactions. We integrated spectral features to improve model transferability. Additionally, we developed machine learning models to predict pedestrian crossing intentions using simulator data, analyzing interactions in both single and multi-vehicle scenarios. We also investigated cross-country behavioral differences and model transferability through a comparative study between Japan and Germany.
Results: For trajectory prediction, incorporating social and pedestrian-vehicle interactions into deep learning models improved accuracy and inference speed. Integrating spectral features using discrete Fourier transform improved motion pattern capture and model transferability. For crossing intention prediction, neural networks outperformed other machine learning methods. Key factors that influence pedestrian crossing behavior included the presence of zebra crossings, time to arrival, pedestrian waiting time, walking speed, and missed gaps. The cross-country study revealed both similarities and differences in pedestrian behavior between Japan and Germany, providing insights into model transferability.
Conclusions: This thesis advances pedestrian behavior prediction and the understanding of pedestrian-vehicle interactions. It contributes to the development of smarter and safer automated driving systems.

Pedestrian safety is a critical global concern, with an urgent need to reduce fatalities caused by pedestrian-vehicle collisions. Machine learning offers a powerful tool for reducing these collisions by improving the prediction of pedestrian behavior. This thesis focuses on predicting and analyzing pedestrian behavior in complex traffic scenarios using machine learning methods.
After reviewing existing studies, we propose deep learning models to improve pedestrian trajectory prediction. These models consider social interactions between pedestrians and their interactions with vehicles, enhancing both accuracy and inference speed. Additionally, we improve model transferability by including spectral features.
We also investigate pedestrian crossing intentions when interacting with vehicles using machine learning methods. Key factors such as the presence of zebra crossings, waiting time, walking speed, and missed crossing chances strongly influence pedestrian behavior. A cross-country comparison between Japan and Germany reveals both similarities and differences in pedestrian behavior, providing valuable insights into model transferability.
Overall, this research advances the prediction of pedestrian behavior, providing insights for safer pedestrian-vehicle interactions in complex scenarios. These findings can guide the development of smarter, safer automated driving systems.
