Spatiotemporal Learning of Multivehicle Interaction Patterns in Lane-Change Scenarios

1 code implementation2 Mar 2020 Chengyuan Zhang, Jiacheng Zhu, Wenshuo Wang, Junqiang Xi

Results demonstrate that our proposed Bayesian nonparametric approach provides an insight into the complicated lane-change interactions of the ego vehicle with multiple surrounding traffic participants based on the interpretable interaction patterns and their transition properties in temporal relationships.

Learning and Inferring a Driver's Braking Action in Car-Following Scenarios

no code implementations11 Jan 2018 Wenshuo Wang, Junqiang Xi, Ding Zhao

A learning-based inference method, using onboard data from CAN-Bus, radar and cameras as explanatory variables, is introduced to infer drivers' braking decisions by combining a Gaussian mixture model (GMM) with a hidden Markov model (HMM).

Driving Style Analysis Using Primitive Driving Patterns With Bayesian Nonparametric Approaches

no code implementations16 Aug 2017 Wenshuo Wang, Junqiang Xi, Ding Zhao

In order to achieve this, first, a Bayesian nonparametric learning method based on a hidden semi-Markov model (HSMM) is introduced to extract primitive driving patterns from time series driving data without prior knowledge of the number of these patterns.

A Learning-Based Approach for Lane Departure Warning Systems with a Personalized Driver Model

no code implementations4 Feb 2017 Wenshuo Wang, Ding Zhao, Junqiang Xi, Wei Han

Second, based on this model, we develop an online model-based prediction algorithm to predict the forthcoming vehicle trajectory and judge whether the driver will demonstrate an LDB or a DCB.

A Rapid Pattern-Recognition Method for Driving Types Using Clustering-Based Support Vector Machines

no code implementations22 May 2016 Wenshuo Wang, Junqiang Xi

To shorten the recognition time and improve the recognition of driving styles, a k-means clustering-based support vector machine ( kMC-SVM) method is developed and used for classifying drivers into two types: aggressive and moderate.
