Quantitative Analysis Of The Impact Of Craft Labor Availability On Construction Project Performance, Hossein Karimi
Quantitative Analysis Of The Impact Of Craft Labor Availability On Construction Project Performance, Hossein Karimi
Theses and Dissertations--Civil Engineering
A shortage of skilled craft labor in the North American construction industry has been an unfortunate cyclic trend since the late 1980s. This shortage has been reported and discussed frequently by numerous past studies in the context of construction industry. The 2008 U.S. recession was at least one period when the craft shortage temporarily improved, as witnessed by spikes in construction unemployment rates above 20% due to the work slowdowns. However, the current economic recovery period is once again experiencing craft shortages in some sectors of the U.S. construction industry. Although the past literature provides wealth of information about influence …
Development Of A Design Based Intersection Safety Performance Evaluation Tool, Adam J. Kirk
Development Of A Design Based Intersection Safety Performance Evaluation Tool, Adam J. Kirk
Theses and Dissertations--Civil Engineering
The purpose of this research is to develop an intersection safety evaluation tool that is capable of assisting designers and planners in the assessment of alternative intersection designs. A conflict exposure model utilizing design hour volumes, intersection configuration and traffic control measures is proposed to achieve this goal. This approach makes use of data typically available for preliminary intersection design. The research goes beyond existing safety performance models which only examine non-directional average daily traffic (ADT) or practices which only account for the geometric and lane configuration of an intersection, such as conflict point analysis.
Conflict prediction models are developed …
