In the domain of autonomous driving systems, vehicle trajectory prediction represents a critical aspect, as it significantly contributes to the safe maneuvering of vehicles within intricate traffic environments. Nevertheless, a preponderance of extant research efforts have been chiefly centered on the spatio-temporal relationships intrinsic to the vehicle itself, thereby exhibiting deficiencies in the dynamic perception of and interaction capabilities with adjacent vehicles. In light of this limitation, we propose a vehicle trajectory prediction algorithm predicated on a hybrid prediction model. Initially, the algorithm extracts pertinent context information pertaining to the target vehicle and its neighboring vehicles through the application of a two-layer long short-term memory network. Subsequently, a fusion module is deployed to assimilate the characteristics of the temporal influence, spatial influence, and interactive influence of the surrounding vehicles, followed by the integration of these attributes. Ultimately, the prediction module is engaged to yield the predicted movement positions of the vehicles, expressed in coordinate form. The proposed algorithm was trained and validated using the publicly accessible datasets I-80 and US-101. The experimental results demonstrate that our proposed algorithm is capable of generating more precise prediction results.

Vehicle trajectory data can reveal actual driving behavior patterns reflected by different road geometric designs, providing important insights for road safety analysis and improvements. This study aims to is to explore the correlation between vehicle trajectory fractal dimension (FD) and highway crash rate (CR) using large-scale telematics trajectory data. Specifically, we propose three methods to measure the FD of vehicle trajectories, and developed fractal parameter estimation technology.

In heterogeneous traffic flow environments, it is critical to accurately predict the future trajectories of human-driven vehicles around intelligent vehicles in real time. This paper introduces a neural network model that integrates both spatial interaction information and the long-term and short-term characteristics of the time series. Initially, the historical state information of both the target vehicle and its surrounding counterparts, along with their spatial interaction relationships, are fed into a Graph Attention Network (GAT) encoder.

The horizontal curvature of railway tracks plays a significant role in vehicle‒track dynamics, and accurate knowledge of the track curvature is essential for vehicle operators to fully understand the running behavior of vehicles. However, it is generally difficult for wagon operators or researchers to obtain track geometry information due to confidential reasons. Using sensors installed on wagons is an alternative to estimate the track curvature.
