− Holistic approach to wheel loaders as complex energy conversion systems − Possible Reduction of fuel consumption by 50% through use of hybrid technology − Considerations of customer segment and business case

This paper reports on research related to avoiding collisions in construction sites using differential GPS technology. In this project, the researchers developed and implemented a system where GPS technology was used in tracking a single vehicle and relaying its information to a central server. Using another simulated vehicle, the server evaluated collision scenarios and sent cautionary message...

Automated action classification of construction workers and equipment from videos is a challenging problem that has a wide range of potential applications in construction. These applications include, but are not limited to, enabling rapid construction operation analysis and ergonomic studies. This research explores the potential of an emerging action analysis framework, Bag-of-Video-Feature-Wor...

Cobb-Douglas Production Function was widely used in economics and productivity studies across many sectors. The function's quantitative modeling of resource inputs and production outputs is appealing to the research domain of construction management. In this thesis we explored this function's application in construction schedule crashing and project risk analysis related to duration of construc...

Project planning functions are to establish project activities, their logical relationships and interrelationships to each other, and the sequences in which they are to be accomplished. The process of assigning activities' duration and identifying the start and completion times of activities and project is considered as project scheduling. Project planning and scheduling is one of the most impo...

Global Navigation Satellite Systems (GNSS) are widely used to document the onand off-site trajectories of construction equipment. Before analyzing the collected data for better understanding and improving construction operations, the data need to be freed from outliers. Eliminating outliers is challenging. While manually identifying outliers is a time-consuming and error-prone process, automati...

Construction accidents with heavy equipment and bad decision making can be based on poor knowledge of the site environment and in both cases may lead to work interruptions and costly delays. Supporting the construction environment with real-time generated three-dimensional (3D) models can help preventing accidents as well as support management by modeling infrastructure assets in 3D. Such model...

Research on occupational accidents on construction sites in Turkey is very few. Moreover, research on motor vehicle and equipment accidents also do not exist. Investigation in the scope of this study shows that after falls and contact with electricity, accidents involving heavy equipment and motor vehicles rank third and fourth, respectively. This study aims to reveal the characteristics of the...

We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...
