Evaluating the safety and efficiency impacts of forced lane change with negative gaps based on empirical vehicle trajectories

Chen, K. (author), Li, Zhibin (author), Liu, Pan (author), Knoop, V.L. (author), Han, Yu (author), Jiao, Y. (author)

A lane-changing (LC) maneuver may cause the follower in the target lane (new follower) to decelerate and give up space, potentially affecting crash risk and traffic flow efficiency. In congested flow, a more aggressive LC maneuver occurs where the lane changer is partially next to the new follower and creates negative gaps, namely negative...

Large Car-following Data Based on Lyft level-5 Open Dataset: Following Autonomous Vehicles vs. Human-driven Vehicles

Li, G. (author), Jiao, Y. (author), Knoop, V.L. (author), Calvert, S.C. (author), van Lint, J.W.C. (author)

Car-Following (CF), as a fundamental driving behaviour, has significant influences on the safety and efficiency of traffic flow. Investigating how human drivers react differently when following autonomous vs. human-driven vehicles (HV) is thus critical for mixed traffic flow. Research in this field can be expedited with trajectory datasets...

Release behavior of soluble salts in MSWI bottom ash used as road basement materials under continuous rainfall conditions

Zhao, Lingqin (author), Zhang, Dongming (author), Hu, Yanjun (author), Guo, Qianqian (author), Jiao, Long (author), Zhou, Nan (author), Di Maio, F. (author)

The bottom ash is increasingly used as a substitute aggregate material in road construction in China, and road salting is the major salt source in groundwater. Continuous rainfall releases soluble salts from the bottom ash subgrade into the surrounding soil and groundwater, resulting in potential hazards. Different methods were employed to...

Inferring vehicle spacing in urban traffic from trajectory data

Jiao, Y. (author), Calvert, S.C. (author), van Cranenburgh, S. (author), van Lint, J.W.C. (author)

This study presents a new method to infer the average two-dimensional (2D) spacing between interacting vehicles in urban traffic from trajectory data. In this context, 2D spacing reflects the amount of road space consumed by pairs of interacting vehicles, and is related to 2D density at the macroscopic level. Due to complex interaction and...

Risk consequence assessment of dam breach in cascade reservoirs considering risk transmission and superposition

Wang, Te (author), Li, Zongkun (author), Ge, W. (author), zhang, Z.H. (author), Zhang, Yadong (author), Sun, Heqiang (author), Jiao, Yutie (author)

Compared with a single reservoir, the risk in cascade reservoirs has the transmission and superposition effect, which increases the complexity of its risk consequence assessment. In view of this problem, the direct consequence (DC) and potential consequence (PC) were defined as two parts of the dam breach risk consequence of cascade reservoirs....

Calculation of dam risk probability of cascade reservoirs considering risk transmission and superposition

Wang, Te (author), Li, Zongkun (author), Ge, W. (author), Zhang, Yadong (author), Jiao, Yutie (author), Sun, Heqiang (author), Zhang, Hua (author)

Because of the risk transmission and superposition among dams in cascade reservoirs, the analysis and probability calculation of dam risk become more complex compared with a single reservoir. By analyzing the main risk sources and actionmechanisms, the disaster-causing factors, disaster-transmitting body and disaster-bearing body in the cascade...

Dam breach has catastrophic consequences for human lives and economy. In previous studies, empirical models are often, to a limited extent, due to the inadequacy of historical dam breach events. Physical models, which focus on simulating human behavior during floods, are not suitable for fast analysis of a large number of dams due to the...

Wang, Liquan (author), Liu, Ziyang (author), Xu, Shida (author), Ouyang, Xiaowei (author), Ouyang, Dong (author), Jiao, Chujie (author), Zhang, Y. (author)

The production of cement leads to a large amount of CO₂ emission. Using industrial waste slag, such as ceramic polishing powder (PP), to replace part of Portland cement can reduce the pollution caused by the cement industry and solid waste disposal. In order to use PP as a replacement for cement, its effects on the properties of...
