MPC Research Reports
Filter by University109 report(s) found for Colorado State University This report describes methods that allow for assessing structural integrity using a direct porting of imaging methods captured by both hand-held and uncrewed aircraft system (UAS)-assisted photography into computational analysis tools to monitor structural degradation of transportation structures. Of... A theoretical framework is developed for applying the material point method (MPM) to problems of modeling natural hazard effects on several representative geometries. Following an outline of the general methodology, in which the structural system is replaced by a combination of integrated Lagrangian... Extreme wind conditions can be a formidable foe to both highway and driver safety. Strong gusts increase the likelihood of wind-induced vehicle crashes, especially for high-sided vehicles (i.e., semi-trucks) in the United States. Current understanding of wind loads on high-sided vehicles comes mostly... This study proposes a new remote sensing technique to measure three-component (3C) dynamic displacement of three-dimensional (3D) structures. A sensing system with an unmanned aerial vehicle (UAV) platform and contact-free sensors (e.g., optical and infrared (IR) cameras) was employed to provide a portable... Reliable and accurate assessment and prediction of bridge condition deterioration is critical for effective bridge preservation. Deterioration models, combined with current condition information, can guide inspection, maintenance, repair, and rehabilitation planning, and support risk and life-cycle analysis.... Train-pedestrian conflicts result in a substantial number of serious and fatal injuries annually. Signs indicating safe and permissible behaviors near railroad rights-of-way are commonly relied upon to mitigate collisions. However, the effectiveness of these signs in preventing accidents depends on the... There is increasing awareness among transportation professionals about the importance of incorporating social equity into their practices. While the transit sector has made notable progress, other areas, such as asset management, are still lagging in integrating social equity into decision making. This... Measuring the dynamic displacements of a structure provides a comprehensive understanding of the structure, especially when subjected to different types of dynamic loading (i.e., wind, traffic, impact loads, blast loads). Despite their usefulness, direct displacement measurements are typically not collected... Connected autonomous vehicle (CAV) technology has the potential to enable significant gains in energy economy (EE). Much research attention has been focused on autonomous eco-driving control enabled by various methods. In this study, the state of the literature on autonomous eco-driving control is reviewed... Potholes are a significant pavement distress compromising safety and causing costly damage. They result from pavement deterioration due to aging, weather, and traffic overloads, with the Mountain Plains region particularly affected due to freeze/thaw cycles. Timely identification and repair of potholes... |
