Liu, X. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)Effective timetable scheduling strategies are essential for passenger satisfaction in urban rail transit networks. Most existing passenger-centric timetable scheduling approaches generate a timetable according to deterministic passenger origin-destination (OD) demands. As passenger OD demands in urban rail transit networks generally show a...journal article 2023

Li, Bo (author), Liu, Qiuhong (author), Wang, T. (author), He, He (author), Peng, You (author), Feng, Tao (author)Outdoor physical activities can promote public health and they are largely influenced by the built environment in different urban settings. Understanding the association between outdoor physical activities and the built environment is important for promoting a high quality of life. Existing studies typically focus on one type of outdoor activity...journal article 2022

Liu, M. (author), Zhao, J. (author), Hoogendoorn, S.P. (author), Wang, M. (author)A joint control approach that simultaneously optimizes traffic signals and trajectories of cooperative (automated) vehicle platooning at urban intersections is presented in this paper. In the proposed approach, the signal phase lengths and the accelerations of the controlled platoons are optimized to maximize comfort and minimize travel delay...journal article 2022

Xiang, Pengcheng (author), Zhang, Qianman (author), Jiang, Qiuyan (author), Liu, Z. (author)Operation risk (OR) has affected sustainable development of urban rail transit (URT) public–private partnership (PPP) projects in China. Balanced distribution of operational risks among stakeholders (the public, government, and private companies) involved in URT PPP projects can maximize overall profit. Quantitative analysis of operational...journal article 2022

Lam, Ka Leung (author), Liu, Gang (author), Motelica-Wagenaar, Anne Marieke (author), van der Hoek, J.P. (author)Many cities have pledged to achieve carbon neutrality. The urban water industry can also contribute its share to a carbon-neutral future. Using a multi-city time-series analysis approach, this study aims to assess the progress and lessons learned from the greenhouse gas (GHG) emissions management of urban water systems in four global cities:...journal article 2022

Liu, S. Y. (author), Lin, S. (author), Wang, Y. B. (author), De Schutter, B.H.K. (author), Lam, W. H.K. (author)In order to better understand the stochastic dynamic features of signalized traffic networks, we propose a Markov traffic model to simulate the dynamics of traffic link flow density for signalized urban traffic networks with demand uncertainty. In this model, we have four different state modes for the link according to different congestion...journal article 2021

Yuan, Dinghuan (author), Yau, Yung (author), Hou, H. (author), Liu, Yongshen (author)Project duration is one of the methods to measure the efficiency of project implementation. This study identifies the factors influencing the project duration of urban village redevelopment projects (UVRPs) in China. Based on the theory of new institutional economics and behavioral economics, this study develops three hypotheses regarding the...journal article 2021

Liu, Wenxiu (author), Meng, Qingyan (author), Allam, Mona (author), Zhang, Linlin (author), Hu, Die (author), Menenti, M. (author)Land surface temperature (LST) in urban agglomerations plays an important role for policymakers in urban planning. The Pearl River Delta (PRD) is one of the regions with the highest urban densities in the world. This study aims to explore the spatial patterns and the dominant drivers of LST in the PRD. MODIS LST (MYD11A2) data from 2005 and...journal article 2021

(author), Fan, Dongli (author), Mao, Ganquan (author), Chen, Aifang (author), Liu, Junguo (author)Efficient and accurate streamflow predictions are important for urban water management. Data-driven models, especially neural network (NN) models can predict streamflow fast, while the results are uncertain in some complex river systems. Physically based models can reveal the underlying physics, but it is relatively slow and computationally...journal article 2021

Zheng, Fangfang (author), van Zuylen, H.J. (author), Liu, Xiaobo (author)Urban travel times are rather variable as a result of a lot of stochastic factors both in traffic flows, signals, and other conditions on the infrastructure. However, the most common way both in literature and practice is to estimate or predict only expected travel times, not travel time distributions. By doing so, it fails to provide full...journal article 2017
