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...journal article 2024

Liu, Xiaotian (author)In Berlin, the public transportation system is large and varied. Train (S-Bahn), tram, metro (U-Bahn), and bus consist of the main skeleton of the system. However, due to historical reasons, most U-bahn and tram lines are located only in the former West and East Berlin, respectively. Thus, lots of transfer stations are located in the area where...master thesis 2023

Liu, Tao (author), Ji, Wen (author), Gkiotsalitis, Konstantinos (author), Cats, O. (author)Transfer optimization in public transport (PT) networks can be achieved through coordinated timetabling and vehicle scheduling. Traditionally, the coordinated timetabling problem is solved first before proceeding to the vehicle scheduling problem. The integration of these two problems can help further reduce the total operation cost and...journal article 2023
