Chasing Target Zero: Contributing Factors Of Fatal Crashes In South Carolina, Matthew Stanley
Chasing Target Zero: Contributing Factors Of Fatal Crashes In South Carolina, Matthew Stanley
All Theses
South Carolina consistently ranks in the top-10 in fatal crashes per 100,000 capita and 100 million vehicle miles traveled. This thesis summarizes an analysis of contributing factors for fatal crashes in South Carolina. A primary objective of this thesis is to investigate differences in contributing factors for fatal crashes as compared to all crashes in South Carolina. 2018 South Carolina fatal crashes (N=970) and all crashes (N=152,973) were analyzed and compared using classic Venn diagrams to compare differences in contributing factors between fatal crashes and all crashes. Fatal, non-fatal, and all crashes were aggregated into one of seven possible contributing …
Theoretical Development And Numerical Validation Of An Asymmetric Linear Bilateral Control Model For An Automated Truck Platoon, M Sabbir Salek
Theoretical Development And Numerical Validation Of An Asymmetric Linear Bilateral Control Model For An Automated Truck Platoon, M Sabbir Salek
All Theses
In this study, the author theoretically develops and numerically validates an asymmetric linear bilateral control model (LBCM) for an automated truck platoon, in which the motion information (i.e., position and speed) from the immediate leading truck and the immediate following truck are weighted differently. The novelty of the asymmetric LBCM is that using this model, all the follower trucks in a platoon can adjust their acceleration and deceleration to closely follow a constant desired time headway at all times to improve platoon operational efficiency while maintaining local and string stability. The author theoretically proves the local stability of the asymmetric …
