A novel agent-based framework for evaluating pedestrian safety at unsignalized mid-block crosswalks
(
Elsevier Ltd
, 2021 , Article)
A critical safety problem in road networks is the conflicts on unsignalized crosswalks. Thus, a proactive approach to assess pedestrian safety performance is required. Simulating the microscopic road user behavior in a ...
Geosynthetic-reinforced soils above voids: Observation and prediction of soil arching
(
Elsevier
, 2021 , Article)
The assumption with the biggest impact on the design of geosynthetic-reinforced soils above voids is the presence and degree of soil arching, which affects the predicted applied stress on the geosynthetic. A series of ...
