LOKI: Long Term and Key Intentions for Trajectory Prediction

Recent advances in trajectory prediction have shown that explicit reasoning about agents' intent is important to accurately forecast their motion. However, the current research activities are not directly applicable to intelligent and safety critical systems. This is mainly because very few public datasets are available, and they only consider pedestrian-specific intents for a short temporal horizon from a restricted egocentric view. To this end, we propose LOKI (LOng term and Key Intentions), a novel largescale dataset that is designed to tackle joint trajectory and intention prediction for heterogeneous traffic agents (pedestrians Figure 1: We show that reasoning about long-term goals and vehicles) in an autonomous driving setting. The and short-term intents plays a significant role in trajectory LOKI dataset is created to discover several factors that may prediction. With a lack of comprehensive benchmarks for affect intention, including i) agent's own will, ii) social interactions, this purpose, we introduce a new dataset for intention and iii) environmental constraints, and iv) contextual trajectory prediction. An example use case is illustrated in information. We also propose a model that jointly performs (a) where we predict the trajectory of the target vehicle. In trajectory and intention prediction, showing that recurrently (b), long-term goals are estimated from agent's own motion.
