A Framework for Pedestrian Sub-classification and Arrival Time Prediction at Signalized Intersection Using Preprocessed Lidar Data

no code implementations15 Jan 2022 Tengfeng Lin, Zhixiong Jin, Seongjin Choi, Hwasoo Yeo

The mortality rate for pedestrians using wheelchairs was 36% higher than the overall population pedestrian mortality rate.

Transformer-based Map Matching Model with Limited Ground-Truth Data using Transfer-Learning Approach

no code implementations1 Aug 2021 Zhixiong Jin, Jiwon Kim, Hwasoo Yeo, Seongjin Choi

In many spatial trajectory-based applications, it is necessary to map raw trajectory data points onto road networks in digital maps, which is commonly referred to as a map-matching process.

Automated Object Behavioral Feature Extraction for Potential Risk Analysis based on Video Sensor

no code implementations8 Jul 2021 Byeongjoon Noh, Dongho Ka, Wonjun Noh, Hwasoo Yeo

In this paper, we propose an automated and simpler system for effectively extracting object behavioral features from video sensors deployed on the road.

A novel method of predictive collision risk area estimation for proactive pedestrian accident prevention system in urban surveillance infrastructure

no code implementations6 May 2021 Byeongjoon Noh, Hwasoo Yeo

Road traffic accidents, especially vehicle pedestrian collisions in crosswalk, globally pose a severe threat to human lives and have become a leading cause of premature deaths.

Vision based Pedestrian Potential Risk Analysis based on Automated Behavior Feature Extraction for Smart and Safe City

no code implementations6 May 2021 Byeongjoon Noh, Dongho Ka, David Lee, Hwasoo Yeo

Despite recent advances in vehicle safety technologies, road traffic accidents still pose a severe threat to human lives and have become a leading cause of premature deaths.

A Real-Time Predictive Pedestrian Collision Warning Service for Cooperative Intelligent Transportation Systems Using 3D Pose Estimation

1 code implementation23 Sep 2020 Ue-Hwan Kim, Dongho Ka, Hwasoo Yeo, Jong-Hwan Kim

To achieve the goal, pedestrian orientation recognition and prediction of pedestrian's crossing or not-crossing intention play a central role.

TrajGAIL: Generating Urban Vehicle Trajectories using Generative Adversarial Imitation Learning

1 code implementation28 Jul 2020 Seongjin Choi, Jiwon Kim, Hwasoo Yeo

A generative model for urban vehicle trajectories can better generalize from training data by learning the underlying distribution of the training data and, thus, produce synthetic vehicle trajectories similar to real vehicle trajectories with limited observations.

Imitation Learning

Traffic Data Imputation using Deep Convolutional Neural Networks

1 code implementation21 Jan 2020 Ouafa Benkraouda, Bilal Thonnam Thodi, Hwasoo Yeo, Monica Menendez, Saif Eddin Jabari

We propose a statistical learning-based traffic speed estimation method that uses sparse vehicle trajectory information.
