Use of incentive/disincentive contracting to mitigate work zone traffic impacts
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if they exceed the completion...
Modeling pedestrian crash severity in St. Louis using random forests and mixed logit techniques
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] The pedestrian-vehicle crashes in the City of St. Louis is a major concern due to the high magnitude of injuries and fatalities compared to Missouri's statewide...
Federated multimodal simulators in transportation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As transportation involves a multiplicity of modes, there is a need to explore multimodal simulators in transportation and the integration of multimodal simulators to enable...
Driving simulator use and calibration for work zone merge sign evaluation
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Work zones on highways have the potential to increase crash risk; therefore, efficient and noticeable signs play a critical role in enhancing highway safety. Some engineers have...
Safety modeling for two certain urban intersection types, HSM calibration, and crash severity distribution
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] According to several years' official crash data, a significant proportion of crashes happened at roadway intersections in Missouri. Of those intersection crashes, a large number...
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)
(TMA), are discussed in this dissertation to illustrate the investigation of smart work zone technologies using mixed simulator and field studies, along with one simulator project investigating interaction between human driven car and autonomous truck...
TMA (track mounted attenuators) involved work zones safety analysis and modeling, using machine learning to predict crash severity and crash frequency in the state of Missouri
(University of Missouri--Columbia, 2018)
When talking about road maintenance safety, it is an unavoidable talking about the TMA usage, as it located in the work zone intended to reduce the damage while crash happened and at the same time protect the related ...
