Show moreThe need to have evacuation plans in place for readily implementation for special need populations has become evident after catastrophic events such as Hurricane Katrina. For the purpose of this research special need populations will include, but are not limited to, people with physical disabilities, senior citizens, non-English speaking populations, residents and employees without vehicles, and tourists. The main objective of this research is to evaluate different evacuation procedures for special need populations from large urban areas utilizing current public transit systems. A microscopic simulation model was constructed to analyze real life scenarios for evacuation methodologies. A linear programming optimization model was developed to find the optimum locations for evacuation bus stops for the case study area. The results from this research were very interesting and can aid evacuation planners in the future.

Show moreAt present the current trip generation models used in the state of Florida to derive residential trip generation rates take into account three variables, dwelling type, auto ownership and household size. It is hoped that by examining geographic location, improvements can be made to the present Florida Standard Urban Transportation Modeling Structure (FSUTMS). To analyze the impact of geographic location, GIS technology will be used. GIS will aid the study in several ways. It will be used to identify urban centers and major highways within the study area and once this is accomplished, GIS will be used to create zones around the selected urban centers and the major highways. Finally GIS will be used to prepare the survey data for statistical analysis. In addition to looking at geographic location, the study will also examine whether certain lifestyle variables can influence residential trip rates within the study area. Throughout this study it is hoped that the predictive power of the Florida Standard Urban Transportation Modeling Structure can be improved.

Tropical storms and mid-latitude cyclones are major drivers of coastal change and damage in coastal communities. Beaches act as a first line of defense against storms, as well as provide recreation, contribute to the economy, and serve as ecological habitat for coastal flora and fauna.

Show moreTropical storms and mid-latitude cyclones are major drivers of coastal change and damage in coastal communities. Beaches act as a first line of defense against storms, as well as provide recreation, contribute to the economy, and serve as ecological habitat for coastal flora and fauna. Throughout the year, meteorological event-driven increases in wave energy result in higher amounts of sediment transport that cause rapid coastal zone morphology alterations and threaten these beach functions. This study uses streamer traps to evaluate cohesionless sediment dynamics in the surf zone and storm-induced morphology change in Boca Raton, Florida. The quantitative and sedimentological characteristics of sediment collected in the bottom streamer trap bins was larger grains with a higher capture weight near the seabed compared to sediment captured in the middle and upper streamer trap bins during both the cold front and the tropical storm. A greater quantity of sediment was captured in transport due to the tropical storm compared to the cold front. Morphology change observed as a result of the cold front included berm erosion, swash zone and foreshore accretion, and erosion beyond the -1.0m contour elevation. Analysis of the morphology observed post-tropical storm included berm accretion, and swash zone and foreshore erosion that continued seaward to the end of the profile. Dean number calculations using pre-cold front sediments and wave parameters predicted erosion, and the post-cold front BMAP measurements confirmed this prediction. Dean number calculations using pre-tropical storm sediments and wave parameters predicted accretion and the post-tropical storm BMAP measurements invalidated this prediction at all capture locations, although above the 1.0m contour the berm did exhibit accretion. Results of this study aim to quantify granulometric differences in event-driven sediment transport in Boca Raton, FL for improved prediction capabilities. Given the current trajectory of climate change, sea-level rise, and increased storm intensity, better understanding the morphological impact of different classes of storms is necessary to ensure and improve coastal resiliency and management.

Show moreUrban freight system constitutes an essential component for both economic and social aspects of the urban areas. However, the driving forces of globalization and ecommerce have adversely affected the volume of freight vehicles in urban roads over the past few decades impacting the sustainability and efficiency of last-mile deliveries. At the same time, the last-mile problem of goods distribution from companies to customers comprises one of the most costly and highest polluting components of the supply chain. Over the past few years, different innovative concepts of autonomous vehicles were introduced to improve last-mile logistic inefficiencies such as traffic congestion and pollution externalities. The objective of this study is to optimize a distribution network consisting of a set of depots and customers by utilizing Autonomous Delivery Robots (ADRs). For that reason, a Mixed Integer Linear Programming model was developed in GAMS for solving the vehicle routing problem while minimizing the total delivery and delay costs of ADRs. This optimization model is based on the route assignment and the required number of ADRs within the network. A heuristic solution algorithm based on the cluster-first, route-second technique was developed in MATLAB for solving the NP-hard problem efficiently. First the customers were clustered to depots based on their maximum distance from them and the maximum allowed number of customers per cluster. After the clustering, the mathematical model was implemented in each cluster providing an exact solution. Three different medium-sized scenarios of 200, 300 and 400 customers were tested under three different clustering instances of a maximum of 20, 30 and 40 customers per cluster and their results were presented and discussed in detail.

Show moreThis thesis examined the road impact fee realities of 11 of Palm Beach County’s public and private sector land development stakeholders. To learn more about how the county’s road impact fee ordinance works in practice, in 2021, 11 stakeholders were interviewed about their experiences with the county’s road impact fee program. Transportation impact fee programs may help relieve development-driven traffic externalities and cost burdens, so long as suitable methodologies are applied (Burge & Ihlanfeldt, 2013; Stahl, 2021). In 2021, Palm Beach County’s road impact fee ordinance required all county development applicants to pay a specified road impact fee dollar amount, regardless of the proposed project’s location and traffic impact, with exceptions (Moore, 2021b; Salour, 2021). Key arguments for and against the county’s road impact fees touch on differences between travel needs, land use patterns, and transit potential in the county’s urban and rural/suburban communities (Clemente, 2021; Hernandez, 2021; Salour, 2021).

Show moreThe project starts from a literature review of the topics from these aspects: the studies of emission models, the eco-driving applications for heavy-duty vehicles (Trucks), Eco-driving and signal control, the benefits from CAVs and Simulation using MOVES and VISSIM. The research on Multiclass/heterogeneous traffic modeling is also reviewed. To define the problem, the research starts with the analysis of the influence the truck percentage has on the individual signalized intersection and on a coordinated signal corridor. The simulation results show the high percentage of heavy-duty vehicles in traffic may significantly degrade the signal control based on the concept of delay optimization mainly considering passenger cars. To solve the problem, an eco-driving strategy for freight mobility control at signalized intersections is introduced. It is by optimizing the travel time while maintaining optimal fuel consumptions and emissions. A two-level dynamic optimization is formulated. An emission weighted optimization is used to simulate vehicles passing the intersection with balanced travel time and emissions savings and compared to a baseline simulation without eco-driving consideration. A jerk penalty is added to ensure safety and comfort. Heavy-Duty Vehicles (HDVs) are the focus of this modeling effort. The emission term in the optimization used an instantaneous speed-acceleration based microscopic fuel consumption models and the results were validated by EPA's MOtor Vehicle Emission Simulator (MOVES) model. The results from this study showed that the weighting factor of the emission term in the objective function reaches an optimal at 0.5. Generally, the proposed method provided dynamic trajectories with slightly longer travel time than the baseline but reduce the emission at about 4% for Nitrogen oxide (NOx) and 7% for carbon dioxide (CO2) for different initial conditions (different distance approaching intersection). Based on the results, an optimal weighting factor of emission term and the range of distances to apply the eco-driving strategy are recommended. A case study is performed to simulate the recommended model, with varying HDV percentages. The test results showed an overall emission reduction of 6% for NOx and 6% for CO2 according to MOVES. To show the relationship between truck percentage and discharge rate, a multiply linear regression is conducted, and the results are shown in the appendix. The data in MOVES and the emission models used are also presented in the appendix.

Show moreTransit Signal Priority (TSP) is an operational strategy that facilitates the movement of transit vehicles, either buses or streetcars, through traffic-signal controlled intersections. As transportation demand increases various transportation networks are facing increasing congestion. To mitigate the high-density impact of congestion on transit operations, TSP is a significant solution and has been widely applied to improve transit service quality and increase bus ridership. TSP can be planed and implemented considering many variables to achieve several valuable benefits such as: reducing transit travel times, better schedule adherence, and better transit efficiency. The objective of this research is to develop warrants and performance standards for transit agencies to implement signal priority based on identified decision factors. The research assesses existing guidelines and provides new guidelines for TSP implementation. Furthermore, this research evaluates the effectiveness of TSP in improving the performance of public transportation bus lines. The improvements are assessed by comparing the total travel time and total delay on the same single corridor with and without TSP applied utilizing microscopic analysis. The results show significant improvements in reducing the travel times and delays for the buses as a result of applying the TSP.

The World Shipping Council (2014) indicates that “it would require hundreds of freight aircraft, many miles of rail cars, and fleets of trucks to carry the goods that can fit on one large liner ship”. According to the data provided by the United Nations Conference on Trade and Development (UNCTAD, 2015), the overall international seaborne trade reached 9.8 billion tons in 2014 with a significant increase of containerized (5.6% in tonnage), dry (2.4% in tonnage), and major bulk cargo (6.5% in tonnage) from 2013. Similar growth is expected to continue. Most of the high-value cargo and general consumer goods are shipped in a containerized form. Liner shipping companies, looking for transport efficiency and economies of scale, have increased vessel size on most of the trade routes. The Journal of Commerce (JOC), 2015 highlights that CMA CGM placed an order for six vessels with 14,000 TEU capacity in the first half of 2015 after an earlier order for three 20,000 TEU vessels. Maersk has recently ordered eleven 19,500 TEU vessels, while MOL and OOCL placed orders for vessels with 20,000 TEU capacity. Note that the number of megaships is projected to increase by at least 13% by 2020 (Journal of Commerce (JOC), 2015).

Specific goals were identified in the National Freight Policy (NFP) to increase economic competitiveness, efficiency, and productivity; reduce congestion; and enhance the safety, security, and resilience of the freight network. A reliable and accessible freight network enables the business to be competitive in the US. However, many urban roadways are facing challenges with traffic volumes being over capacity during peak periods. As a result, time and money are lost due to traffic congestion. Operational and design constraints such as interchange, steep grade, signalized intersection, work zone, merging, lane drop, and others, could contribute additional delays for commercial vehicles. This study leveraged our previous effort to measure and identify truck bottlenecks in the Twin Cities Metropolitan Area (TCMA) by using the National Freight Performance Management Research Data Set (NPMRDS). The research team worked with stakeholders to prioritize a list of key truck corridors in the TCMA.

Show moreFreeway network analysis tools often use simplified link performance functions to relate travel time to traffic demand. Such functions are typically not sensitive to the level of commercial truck presence in the traffic stream are therefore of limited value in analyzing freeway network level operational policies that need to explicitly consider commercial truck traffic (e.g., truck lane restrictions or truck-only lanes). Furthermore, travel time reliability (TTR) is taking on increased emphasis in traffic operations analyses. Microsimulation is a tool that can potentially be used for network-level analyses, but when combined with TTR analysis, the computational burden can be problematic. The Highway Capacity Manual (HCM) freeway facility TTR analysis methodology is less computationally intensive than microsimulation and is more sensitive to traffic stream vehicle composition than typical network analysis link performance functions. However, this methodology is currently only applicable at the facility, not network, level. This project extends the HCM freeway TTR analysis methodology to the network level by integrating user equilibrium (UE) traffic assignment. The proposed freeway network TTR analysis methodology generates scenarios that represent the impacts of origin-destination (OD) demand variation, weather events, incident events, and work zone events on the freeway network. For each scenario, UE traffic assignment is performed for the freeway network, and the method of successive average (MSA) is applied to solve the UE traffic assignment. Travel times (and/or other performance measures) obtained from all the scenarios are aggregated into various distributions of interest, such as the network-, facility-, and OD-level distributions, and TTR performance measures are calculated at the three different levels. In addition, a software tool was developed based on the revision and integration of two existing software programs. The software tool provides a convenient and efficient approach for transportation planners and researchers to conduct the freeway network TTR analysis methodology.

Show moreFreight transportation provides a significant contribution to our nation’s economy. A reliable and accessible freight network enables business in the Twin Cities to be more competitive in the Upper Midwest region. Accurate and reliable freight data on freight activity is essential for freight planning, forecasting and decision making on infrastructure investment. A report entitled “Twin Cities Metropolitan Region Freight Study” published by MnDOT and the Metropolitan Council in 2013, suggested a need to understand where and when trucks are most affected by congestion. A framework for truck data collection and analysis was recommended to better understand the relationships between truck traffic and congestion in rush hours. Building upon our previous study to measure freight mobility and reliability along 38 key freight corridors in the Twin Cities Metropolitan Area (TCMA), this study leveraged our previous effort to implement the performance measures using the National Performance Measurement Research Dataset (NPMRDS) from the USDOT. The researcher team first worked with stakeholders to prioritize a list of key freight corridors with recurring congestion in peak periods in the TCMA. We used 24 months of NPMRDS data to measure travel time reliability and estimate truck delay at the corridor level and to identify system impediments during the peak hours. The objective is to use performance measures for assessing impact of truck congestions and identifying operational bottlenecks or physical constraints. Trucking activity nearby a congested area is examined to analyze traffic pattern and investigate possible causes of recurring congestions.

Show moreIn the past decade, unmanned aerial vehicles (UAV) have become increasingly more popular in the commercial sector. Drones are being used for all kinds of purposes, such as surveillance, inspecting architecture, filming, wildlife research, and more. Freight delivery is a potential application that is getting lots of attention from large companies. This research presented novel data, relationship, and models for deliveries utilizing small UAVs. Small UAVs were defined as aircrafts with a tare of up to 15 kilograms (kg) and a potential payload of up to 15 kg. Since the weight of the UAVs is capped, only drones with engines that are electric were included; noise and pollution problems are likely to hinder urban deployments of internal combustion engines. Internal combustion engines are mostly used in larger UAVs. The scope of the search was limited to multicopter drones that can potentially deliver in both urban and rural areas. Fixed-wing drones were excluded from the search because currently only copters have the capability of hovering and delivering products in tight spaces (required in urban areas); fixed-wing UAVs typically cannot land or take off vertically. Single copters can hover similarly to helicopters, but were not included in the search because these aircrafts tend to be larger, and the size of the propeller and blade made them unsafe for areas without a large. Multicopters or multi-rotor drones can hover but also have higher stability and maneuverability, which makes them more suitable for navigating tight spaces or flying near humans and/or valuable property.

Show moreOver the last few years, a rapid explosion of new technologies has created opportunities to address critical freight transportation challenges in urban, suburban, and rural areas. These innovations include truck platooning, smart parking systems, collaborative and shared logistics techniques, and connected autonomous vehicles. These new technologies are influencing consumer behavior and reshaping freight supply chain management at the urban, regional, and international level. In order to understand how these innovations are changing the field of freight transportation, it is essential to understand how organizations choose to adopt innovations. Adoption methods available from consumer behavior research are mostly based on individuals, and there is limited material on the behavior of organizations in regards to innovation adoption. The general adoption methods cannot be directly used in modeling adoption of innovations by organizations without further study and modifications. Approaches to innovation adoption can be broken into two sections: theoretical and methodological approaches. The theoretical approaches attempt to identify the forces that cause an organization to accept or reject an innovation. Once the forces have been identified, the theoretical approaches explain how the forces interact and influence the adoption process. Methodological approaches are composed of modeling techniques which can be applied to innovations in order to generate predictions of adoption patterns. By identifying the benefits and drawbacks of each approach, it is possible to select the most appropriate theoretical and methodological approach for organizational adoption.

Show moreThis study aims to address the unique challenges of transportation in rural and disconnected communities through innovative data-driven methodologies. The primary methods employed in this research involve Geographic Information Systems (GIS) tools and simulation techniques to model and assess the impact of flood zones on rural traffic dynamics. The study recognizes the distinct mobility patterns and limited infrastructure prevalent in rural areas, emphasizing the need for tailored solutions to manage flood-induced disruptions. By leveraging GIS tools, the study intends to spatially analyze existing transportation networks, population distribution, flood-prone areas, and key points of interest to formulate a comprehensive understanding of the local context. Simulation-based approaches using the PTV VISSIM platform will be employed to model and assess various flood scenarios and their effects on traffic flow and accessibility. This study’s outcomes aim to contribute valuable insights into improving accessibility, efficiency, and safety in transportation for these underserved areas during flood events. By combining GIS tools and simulation techniques, this research seeks to provide a robust framework for data-driven decision-making and policy formulation in the realm of rural and disconnected community mobility, particularly in the context of flood risks.

Show moreThe demand on transportation infrastructure is dramatically increasing due to population growth causing the transportation systems to be pushed to their limits. With the projected population growth, not only for the U.S. but especially for the higher education field, university campuses are of great importance for transportation engineers. Urban univeristy campuses are considered major trip generators and with the population forecast many challenges are bound to arise. The implementation of an improved transit system provides a lower-cost solution to the continuously increasing congestion problems in university campus road networks and surrounding areas. This paper presents a methodology focused on the development of a hybrid system concentrated in three main aspects of transit functionality : access to bus stop location, reasonable travel time and low cost. Two methods for bus stop locations assessment are presented for two levels of analysis : microscopic and mesoscopic. The resulting travel time from the improved bus stop locations is analyzed and compared to the initial conditions by using a microsimulation platform. The development of a mathematical model targets the overall system's cost minimization, including user and operator cost, while maximizing the service coverage. The results demonstrate the benefits of the bus stop assessment by the two applied methods, as well as, the benefits of the route and headway selection based on the mathematical model. Moreover, the results indicate that the generation of routes using travel time as the impedance factor generates the optimal possible routes to obtain the minimum system's overall cost.
