Classification of airborne laser scanning point cloud using point-based convolutional neural networkZhu, Jianfeng (author), Sui, Lichun (author), Zang, Y. (author), Zheng, He (author), Jiang, Wei (author), Zhong, Mianqing (author), Ma, Fei (author)In various applications of airborne laser scanning (ALS), the classification of the point cloud is a basic and key step. It requires assigning category labels to each point, such as ground, building or vegetation. Convolutional neural networks have achieved great success in image classification and semantic segmentation, but they cannot be...journal article 2021

Chen, Yifei (author), Li, Meng (author), Zheng, Shuli (author), Lal, C. (author), Conti, M. (author)Ride-Hailing Service (RHS) has motivated the rise of innovative transportation services. It enables riders to hail a cab or private vehicle at the roadside by sending a ride request to the Ride-Hailing Service Provider (RHSP). Such a request collects rider’s real-time locations, which incur serious privacy concerns for riders. While there are...conference paper 2021

Zheng, X. (author), Gonzalez Acosta, J.L. (author), Remmerswaal, G. (author), Vardon, P.J. (author), Pisano, F. (author), Hicks, M.A. (author)The material point method (MPM) shows promise for the simulation of large deformations in history-dependent materials such as soils. However, in general, it suffers from oscillations and inaccuracies due to its use of numerical integration and stress recovery at non-ideal locations. The development of a hydro-mechanical model, which does not...conference paper 2021

A dynamic OD prediction approach for urban networks based on automatic number plate recognition dataLiu, Jing (author), Zheng, Fangfang (author), van Zuylen, H.J. (author), Li, Jie (author)OD flows provide important information for traffic management and planning. The prediction of dynamic OD matrices gives the possibility to apply anticipatory traffic management measures. In this paper, we propose an OD prediction approach based on the data obtained by Automated Number Plate Recognition (ANPR) cameras. The principal component...journal article 2020
