Analysis Of Transit Accessibility For People With Disabilities, Rostam Khalid Mohammed Ameen Qatra
Analysis Of Transit Accessibility For People With Disabilities, Rostam Khalid Mohammed Ameen Qatra
Masters Theses
The inconvenience of public transit systems and unavailability of bus stops in the United States has resulted in a heavy reliance on the private automobile. One of the main issues in transit services is accessibility, particularly for people with disabilities. This research is intended to compare estimated job accessibility measures by transit in Kalamazoo county for workers with reduced physical mobility and without. Using OpenTripPlanner (OTP) software, General Transit Feed Specification (GTFS), Open Street Map (OSM) and Longitudinal Employer-Housing Dynamics (LODES) data were analyzed to estimate job accessibility for people with mobility constraints. By using the shortest tree path method, …
Safety Benefit Analysis Of Alternative Delineation Practices In Michigan, Brenda C. Burdick
Safety Benefit Analysis Of Alternative Delineation Practices In Michigan, Brenda C. Burdick
Masters Theses
Among the many aspects of roadway design, one important system is roadway delineation. The main purposes of roadway delineation include regulating, warning, and guiding drivers in a safe manner. Delineation systems have the potential to reduce crashes. This research sought to perform safety benefit analysis of roadway delineation practices in Michigan. Through literature review, several delineation practices, selection criteria, and previously developed crash modification factors were researched. Even though several pavement marking materials have been implemented in Michigan, a safety benefit analysis of various materials had not been performed. Sites were selected, and pavement marking material inventory data were combined …

Verifying Automated Prestressed Concrete Design Software For Mdot Bridge Design Standards, Hussein Kadhim Abood Khalaf
Masters Theses
The design and analysis of bridges is a very critical and time consuming process. The automation of bridges design can save us time and effort, but the designer must have enough background with structural design of bridges in order to be able to analyze and understand the output of the automated design. This research shows the design and analysis of the superstructure of the US-27 Interchange Bridge at M-57 in Gratiot County of Washington Township, Michigan. The main purpose of this research is to establish a comprehensive design example following AAHTO LRFD Bridge Design Specifications and Michigan Bridge Design Manual. …
Comparison Of Safety And Operational Performances For Three Engineering Countermeasures, Ali Hamzah Hussein Alzuhairi
Comparison Of Safety And Operational Performances For Three Engineering Countermeasures, Ali Hamzah Hussein Alzuhairi
Masters Theses
While there have been many studies on engineering treatments for reducing traffic crashes or for improving intersection efficiency, few studies have been simultaneously taking both impacts into consideration. This thesis analyzed impacts of engineering countermeasures and determines when these countermeasures are cost effective with respect to the amount of traffic and the number of crashes. Both crash reduction and operational costs were compared for analysis. This study specifically investigated three countermeasures: changing from permitted to protected for a left-turn on minor approaches, leading pedestrian interval (LPI), and exclusive pedestrian phase (Barnes Dance). The general Safety Performance Functions (SPFs) from the …
Developing Standard Procedures For Structural Aspects Of Slide-In Bridges In Accelerated Bridge Construction (Abc), Ozan Utku Ridvanoglu
Developing Standard Procedures For Structural Aspects Of Slide-In Bridges In Accelerated Bridge Construction (Abc), Ozan Utku Ridvanoglu
Masters Theses
Slide-in bridge construction (SIBC) is a special method especially used to replace an existing bridge with the minimum duration road closure. In this method, new bridge superstructure is built next to the existing one and it is slid to its final position after demolishing the existing one. Applied implementations of SIBC show that several complications are experienced during bridge slide related with surface interaction. There is a need to evaluate the structural components of SIBC to develop suggestions. In this research, structural components of SIBC were investigated. The research dealt with completed SIBC implementations and numerical modelling of the slide …
