Stochastic Programming Models For Electric Vehicles’ Operation: Network Design And Routing Strategies, Seyed Sajjad Fazeli
Wayne State University Dissertations
Logistic and transportation (L&T) activities become a significant contributor to social and economic advances throughout the modern world Road L&T activities are responsible for a large percentage of CO2 emissions, with more than 24% of the total emission, which mostly caused by fossil fuel vehicles. Researchers, governments, and automotive companies put extensive effort to incorporate new solutions and innovations into the L&T system. As a result, Electric Vehicles (EVs) are introduced and universally accepted as one of the solutions to environmental issues. Subsequently, L&T companies are encouraged to adopt fleets of EVs. Integrating the EVs into the logistic and transportation …
Empirical Study Of Basic Violations, Pay Incentives, And Safety: Evidence From U.S. Intrastate Carriers, Shengyang Ju
Empirical Study Of Basic Violations, Pay Incentives, And Safety: Evidence From U.S. Intrastate Carriers, Shengyang Ju
Wayne State University Dissertations
Truck drivers are under financial pressure due to inadequacy in their compensation. Thus, they have strong incentives to work more legally or illegally in pursuing a higher income, which leads to fatigue and HOS violations and ultimately causes crashes. On the other hand, FMCSA oversees the motor carrier’s safety performance and tries to improve the current safety measurement since everyone pays a share of the economic costs due to the externality. This dissertation aims to explore the complex relationship between BASICs violations, pay incentives and crashes, to raise the importance of economic impact on carrier’s safety, and to test the …
Data Driven Approach To Characterize And Forecast The Impact Of Freeway Work Zones On Mobility Using Probe Vehicle Data, Mohsen Kamyab
Data Driven Approach To Characterize And Forecast The Impact Of Freeway Work Zones On Mobility Using Probe Vehicle Data, Mohsen Kamyab
Wayne State University Dissertations
The presence of work zones on freeways causes traffic congestion and creates hazardous conditions for commuters and construction workers. Traffic congestion resulting from work zones causes negative impacts on traffic mobility (delay), the environment (vehicle emissions), and safety when stopped or slowed vehicles become vulnerable to rear-end collisions. Addressing these concerns, a data-driven approach was utilized to develop methodologies to measure, predict, and characterize the impact work zones have on Michigan interstates. This study used probe vehicle data, collected from GPS devices in vehicles, as the primary source for mobility data. This data was used to fulfill three objectives: develop …
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 …
Resident-Led Urban Agriculture And The Hegemony Of Neoliberal Community Development: Eco-Gentrification In A Detroit Neighborhood, Theodore Pride
Resident-Led Urban Agriculture And The Hegemony Of Neoliberal Community Development: Eco-Gentrification In A Detroit Neighborhood, Theodore Pride
Wayne State University Dissertations
This dissertation employs a Gramscian framework as an alternative approach to understand the utilization of neoliberal community-based development—which advocates free-market schemes to development, and a refocus from institutional and structural causes of poverty to endogenous community forces (social capital and community capacity building)—by low-income residents in hyper-abandoned and disinvested urban neighborhoods. Using a case study of resident-led neighborhood development in the low-income neighborhood of Brightmoor in Detroit, Michigan, I show how “everyday discourse” of urban decline in Detroit and the possible rehabilitation of the city shape the “common sense” understanding of the “problem-and-solution equation” associated with the process of neighborhood …
Analysis Of Queue Characteristics At Signalized Intersections Near Highway-Railroad Grade Crossing, Amna Chaudhry
Analysis Of Queue Characteristics At Signalized Intersections Near Highway-Railroad Grade Crossing, Amna Chaudhry
Wayne State University Dissertations
Analysis of traffic queues at signalized intersections which are in close proximity to highway- railroad grade crossings is of primary importance for determining if the normal signal operation needs to be preempted for railroad operations by providing a special signal mode for safe clearance of the queued vehicles from the tracks before the train arrival, and prohibiting any conflicting traffic movements towards the crossing. Such queuing analysis becomes even more critical where direct observations of traffic queues are not possible or where the assessment is needed for a future location. Inadequate estimation of queues from signalized intersections to the nearby …
An Integrated Framework For Freight Forwarders:Exploitation Of Dynamic Information For Multimodal Transportation, Farshid Azadian
An Integrated Framework For Freight Forwarders:Exploitation Of Dynamic Information For Multimodal Transportation, Farshid Azadian
Wayne State University Dissertations
Advent of real-time information broadcasting technologies, growth in demand for air-cargo, and increased congestion and variability on air-road network, are the main forces compelling today's air-freight forwarders to improve their operational decision-making to be more competitive and responsive to needs of customers. This research studies the air-cargo transportation on both road (short-haul) and air (long haul) network from the perspective of a mid-size freight forwarder.
We develop a routing algorithm for congestion avoidance on air-network based on historical data and introduce an innovative approach to incorporate real-time information to enable dynamic routing of cargo on a stochastic air-network. In the …
A Needs Assessment Of Knowledge, Skills, And Values For Urban Planning Professionals Based On Competencies Set Forth By Professional Planning Organizations, Chade Saghir
Wayne State University Dissertations
Continuing education and training is pivotal in today's fast-paced technology driven society. A profession is defined by the theories and techniques that competent practitioners utilize in their everyday work. Therefore, determining the competencies that practitioners must possess for any given profession is a prerequisite for a respected profession. Most professions are bounded by competencies that are dictated by professional organizations and education programs, yet the real test is how practitioners view these competencies as they relate to their job. For a profession to reach the ultimate goal of improving society the first step is to align professional organization, education, and …

Roadway maintenance and repair has become increasingly commonplace in the United States over the past several decades as our roadway infrastructure has continued to age and deteriorate. Maintenance and repair work on an existing roadway often presents the challenge of maintaining traffic on the existing roadway while work is being performed, thereby necessitating the use of what is commonly referred to as a roadway "work zone". One …

Characteristics And Causal Factors Of Claims In Michigan Highway Construction Projects, Abel K. Sahlool
Wayne State University Dissertations
The US highway system is the largest road network system in the world. MDOT administers about 9,722 route-miles, (28,000 lane-miles) of roadway networks in Michigan. Every year, hundreds of projects worth millions of dollars are let by the State Transportation Agency (STA).
Majority of these projects are successfully completed within the original scope of work, budget, schedule, and without litigation. However; some projects end up in litigation and disputes costing tax payers a great amount of money and the STA a great amount of resources. The number and cost of these construction claims has been substantially increasing in recent years. …
Dynamic Routing On Stochastic Time-Dependent Networks Using Real-Time Information, Ali R. Guner
Dynamic Routing On Stochastic Time-Dependent Networks Using Real-Time Information, Ali R. Guner
Wayne State University Dissertations
In just-in-time (JIT) manufacturing environments, on-time delivery is one of the key performance measures for dispatching and routing of freight vehicles. Both the travel time delay and its variability impact the efficiency of JIT logistics operations, that are becoming more and more common in many industries, and in particular, the automotive industry. In this dissertation, we first propose a framework for dynamic routing of a single vehicle on a stochastic time dependent transportation network using real-time information from Intelligent Transportation Systems (ITS). Then, we consider milk-run deliveries with several pickup and delivery destinations subject to time windows under same network …
Examination Of Factors Affecting The Frequency, Response Time, And Clearance Time Of Incidents On Freeways, Indrajit Ghosh
Examination Of Factors Affecting The Frequency, Response Time, And Clearance Time Of Incidents On Freeways, Indrajit Ghosh
Wayne State University Dissertations
Traffic incidents are the primary cause of non-recurrent congestion in urban areas, resulting in reductions in roadway capacity and significant safety hazards to other motorists, as well as first responders. Many communities have initiated incident management programs that detect and respond to incidents and restore freeways to full capacity by clearing the incident scene as soon as possible. In the Detroit metro area, the Michigan Department of Transportation (MDOT) operates a Freeway Courtesy Patrol (FCP) program as part of its larger freeway incident management program from the Michigan Intelligent Transportation Systems (MITS) Center in downtown Detroit. The MITS Center maintains …
