• Abstract: Understanding how pedestrians adjust their movement when interacting with autonomous vehicles (AVs) is essential for improving safety in mixed traffic. This study examines micro-level pedestrian behaviour during midblock encounters in the NuScenes dataset using a hybrid discrete choice-machine learning framework based on the Residual Logit (ResLogit) model. The model incorporates temporal, spatial, kinematic, and perceptual indicators. These include relative speed, visual looming, remaining distance, and directional collision risk proximity (CRP) measures. Results suggest that some of these variables may meaningfully influence movement adjustments, although predictive performance remains moderate. Marginal effects and elasticities indicate strong directional asymmetries in risk perception, with frontal and rear CRP showing opposite influences. The remaining distance exhibits a possible mid-crossing threshold. Relative speed cues appear to have a comparatively less effect. These patterns may reflect multiple behavioural tendencies driven by both risk perception and movement efficiency.

  We introduce the GPT style next token motion prediction into motion prediction.

We propose to adopt three factorized attention modules with different neighbors for information aggregation and different position encoding styles to capture their relations.

  In traffic scenes, when encountering with oncoming people, pedestrians may make sudden turns or stop immediately. To predict such unpredictable trajectories, we can gain insights into the interaction between pedestrians. We present a novel generative method named Spatial Interaction Transformer (SIT), which learns the correlation of pedestrian trajectories through attention mechanisms.

  Traffic violation and the flexible and changeable nature of pedestrians make it more difficult to predict pedestrian behavior or intention. In combination with pedestrian motion state and other influencing factors, pedestrian intention can be predicted to avoid unnecessary accidents. This paper verifies the proposed algorithm on the JAAD public dataset, and the accuracy is improved by 11.6% compared with the existing method.
