A Hierarchical Modelling Approach For Assessing The Impact Factors Of The Measured Of Mobility And Safety At Intersections, Hiba Eyesha Abou-Kassem
A Hierarchical Modelling Approach For Assessing The Impact Factors Of The Measured Of Mobility And Safety At Intersections, Hiba Eyesha Abou-Kassem
Civil and Environmental Theses
Measuring safety and mobility for various types of intersections is crucial in any transportation study. Many factors contribute to changing the effectiveness of the different types of intersections on mobility and safety. Deciding which type of intersection is most suitable in a particular environ and prevailing traffic conditions depends on the number of crashes, injuries, delay time, etc. This study focuses on two intersection types; signalized intersections and non-signalized intersections (only roundabouts). The aim of this research is to devise a theoretical modeling framework and hence a statistical-based methodology that can be used to assess the safety and mobility measures …
A Recommendation To Implement "Spanish In Construction" Topics Course, Benjamin W. Dimer
A Recommendation To Implement "Spanish In Construction" Topics Course, Benjamin W. Dimer
Construction Management
The purpose of this report is to recommend the addition of a Spanish in Construction class to the Construction Management curriculum. Many of Cal Poly’s graduates enter a construction workforce which is composed heavily of Hispanic and Latino members. Historically, Hispanics and Latinos account for not only the most rapidly growing populations of construction, but also the most proportionally at-risk. In an industry as dangerous as construction, it is important that students are well-rounded and well-prepared to contribute as safely, efficiently, and flawlessly as possible. Thorough literature review and an interview of part-time Cal Poly lecturer and industry veteran, Eric …
Using Lidar Data To Analyze Access Management Criteria In Utah, Marlee Lyn Seat
Using Lidar Data To Analyze Access Management Criteria In Utah, Marlee Lyn Seat
Theses and Dissertations
The Utah Department of Transportation (UDOT) has completed a Light Detection and Ranging (LiDAR) data inventory that includes access locations across the UDOT network. The new data are anticipated to be extremely useful in better defining safety and in completing a systemwide analysis of locations where safety could be improved, or where safety has been improved across the state. The Department of Civil and Environmental Engineering at Brigham Young University (BYU) has worked with the new data to perform a safety analysis of the state related to access management, particularly related to driveway spacing and raised medians. The primary objective …
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 …
Evaluation Of Milwaukee B And Synchronized As New Service Interchange Designs, Amirarsalan Mehrara Molan
Evaluation Of Milwaukee B And Synchronized As New Service Interchange Designs, Amirarsalan Mehrara Molan
Wayne State University Dissertations
These days, alternative interchanges are attracting the attention of transportation
agencies and designers more than ever. Most of the existing interchanges in the U.S
were built in the 1950s and 1960s when traffic volume was much lower, and the type of
vehicles and driving habits were completely different. Moreover, the knowledge of
highway design and safety is more developed now, and this provides an appropriate
situation to increase the efficiency of interchanges regarding traffic operation and safety
using alternative interchanges.
This research evaluated the performance of two proposed service interchange
designs—the synchronized design which is related to a superstreet intersection …
Impact Of Connected Vehicle Safety Applications On Driving Behavior At Varying Market Penetrations: A Driving Simulator Study, Matthew Alexander Theriot
Impact Of Connected Vehicle Safety Applications On Driving Behavior At Varying Market Penetrations: A Driving Simulator Study, Matthew Alexander Theriot
LSU Master's Theses
The studies conducted in this thesis evaluate the safety benefits of a blind spot warning (BSW) application and a do not pass warning (DNPW) application at low, medium, and high market penetrations (MP) of connected vehicles (CV) using a high-fidelity driving simulator. Using vehicle-to-vehicle (V2V) communication, CVs can exchange information to alert drivers of potential safety hazards and reduce potential crashes during lane change and overtaking maneuvers. A CV testbed was developed to relay visual and auditory warnings when dangerous thresholds were met for each application. For the BSW a proximity-based threshold was used to trigger a warning as a …
