Artificial intelligence techniques for modeling dynamic traffic behavior at bottlenecks
(University of Missouri--Columbia, 2014)
Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
In 2014, nearly 10% of overall congestion on freeways was due to the presence of work zones (WZs), equivalent to 310 million gallons of fuel loss (FHWA, 2017a). In terms of safety, in the US, every 5.4 minutes, a WZ related ...
Surrogate measures for evaluating new signage and intersection designs
(University of Missouri--Columbia, 2016)
Transportation agencies faced with the challenge of enhancing safety on roadways are looking for alternative solutions to designing roads and signage. When deciding whether the alternative design is superior to the traditional ...
Traffic impact assessment and mitigation strategies for disruptions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation research focuses on modeling traffic conditions affected by disruptive events such as work zones, incidents, and hurricanes. Using a ...
Modeling transportation impacts of natural disasters
(University of Missouri--Columbia, 2021)
Natural disasters such as hurricanes and pandemics cause significant disruption in people's lives. This research aims to model such disasters' transportation impacts using state-of-the-art simulation methods, statistical ...
Safety analysis of freeway interchange speed change lane facilities
(University of Missouri--Columbia, 2022)
[EMBARGOED UNTIL 5/31/2024] The entrance speed change lane is an uncontrolled terminal between the entrance ramp and freeway, with the primary purpose of creating a merging area for entering vehicles. The exit speed change ...
Evaluation of an autonomous truck mounted attenuator system in work zones
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] Improving work zone safety is a priority for state and local transportation agencies. Mobile and slow-moving operations experience another threat in the form of errant vehicles crashing into the ...
