Measuring Landscape Performance: Case Study Investigation, Hannah Michelle Lopresto, Brandon Zambrano, Catherine De Almeida

UCARE: Research Products

Participating in the Landscape Architecture Foundation’s 2018 Case Study Investigation has been an incredibly informative experience for our research team at the University of Nebraska-Lincoln. We are eager to shine a spotlight on the landscape performance of two Great Plains projects: P Street Corridor, a revitalized downtown streetscape in Lincoln, Nebraska, and Tom Hanafan River’s Edge Park, a waterfront redevelopment in Council Bluffs, Iowa. Working on the post-occupancy study of both projects has been extremely beneficial in understanding how reclaiming underutilized sites can create high-performing landscapes. Both are public projects in urban settings with primary goals of transforming formerly unpleasant, …

The Cost Of Jaywalking On Traffic Congestion In An Intersection In Greater Cairo: A Case Study, Hussein Gawdat

Theses and Dissertations

There have been many studies focusing on different types of traffic delays, pedestrians’ interaction at signalized intersections and economic losses as a result of these delays. However, there is a huge gap in the current literature, regionally and globally, in studying the traffic delays associated with jaywalking. In Egypt, jaywalking is considered a common phenomenon, however, population increased drastically over the past decades in Greater Cairo leading to more congested streets. This research provides a case study that investigates the economic effect of jaywalking on traffic flow in Mashaal, a sample location in Greater Cairo, due to traffic congestion. The …

Assessment Of The Potential Of Proposed Stations Of The California High-Speed Rail As Major Hubs For Physical And Economic Development, Seitu Akira Coleman

Master's Theses

This study investigated the potential for development of station catchment areas around the proposed California High-Speed Rail System. The study was prompted by a review of practices of Japanese railway company groups that engage not only in train operations, but also in business diversification and property development within the station areas of their lines. These actions allow the company groups to diversify their revenues streams, increase ridership on their lines, and operate as a whole with net profits. This is in contrast to transit agencies in the United States, which only focus on transporting passengers along their lines and do …

Road Diet Feasibility Analysis For Nebraska, Brandon L. Purintun

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Many rural towns and cities throughout Nebraska have experienced consistent population decline over the past 50 years, and the highway system once built to accommodate hoped-for growth is not serving the population as well as it could. These towns and cities would benefit from implementing a road diet conversion on their main highways. Within rural communities, road diets are an increasingly popular method of improving safety along major arterials through the reduction of excess capacity in favor of increasing refuge areas for turning vehicles. A typical application might be the restriping of a four-lane undivided highway into a three-lane highway …

A Methodological Framework For Quantifying Impacts Of Truck Traffic On Regional Network With Implications To Transport Policy, Chaitanya Narendra Pathak

Dissertations

Increased global trade has promoted the importance of shipping industry and the introduction of mega-ships has created an opportunity to be more cost-effective. Because of this, the expected change in freight transportation influences the operating regimes and schedules at the port terminals. Trucks being the predominant mode of transportation used to carry the freight transport, there is a growing concern about the impact of trucks in the region. The problems are further expected to grow as the improvements to resolve them are hindered by funding shortfalls. Public agencies are therefore involved in developing comprehensive state freight plans that outline immediate …

The Impact Of Project Delivery Methods On Dispute Occurrence In Public Highway Projects, Samaneh Nasrollahi, Ghada M. Gad, Alan Atalah

Master of Technology Management Plan II Graduate Projects

The construction industry is a complex and competitive industry in which different participants with different expertise, talents, and levels of knowledge work together to achieve their objectives and complete a project. Sine different participants with different interest involve in a construction project, therefore, conflicts arise and become inevitable. Conflicts in projects will cause an adversarial environment which result to disputes. Hence, if conflicts are not well managed and resolved in a timely manner, they quickly turn into disputes, which prevent the successful completion of the construction project, in terms of cost and time, and increasing the potential for poor project …

Measuring Access To Employment To Guide And Evaluate Public Transit Service Planning In New Orleans, Kevin Harrison

LSU New Orleans Theses and Dissertations

New software and technology is making it easier than ever before for public transportation planners to evaluate how quickly residents can reach jobs and other destinations. Because in the past it was difficult to measure access to opportunities, these concepts remained primarily in the theoretical and academic realms of research. This thesis reviews methods that could be used to evaluate routine bus service improvements and performs a comparative analysis of different methods in the context of New Orleans. There are many different variables in how the analysis could be performed, but this thesis focuses on the role that time of …

Dynamic Green Split Optimization In Intersection Signal Design For Urban Street Network, Peng Jiao

Open Access Theses

In the past few decades, auto travel demand in the United States has significantly increased, but roadway capacity unfortunately has not expanded as quickly, which has led to severe levels of highway traffic congestion in many areas. In theory, the problem of congestion addressed through demand management and roadway expansion. However, system expansion in urban areas is difficult due to the extremely high cost of land; therefore, maximizing the existing capacity therefore often is considered the most realistic option. In urban areas, most of the traffic congestion and delays typically occur at signalized intersections. This thesis aims to prove the …

As a guide for planners and policymakers, the objective of this thesis is to develop a strong foundation for anticipating the potential impacts resulting from advancements in vehicle automation. To establish the foundation, this thesis uses a robust qualitative methodology, coupling a review of literature on the potential advantages and disadvantages of vehicle automation and lessons from past innovations in transportation, with recent trends of the Millennial Generation, …

Exploring Transit Ridership Using Census, Routing & Scheduling, And Stop Characteristic Data, Douglas Harvey Moody

Master's Theses

This study develops, analyzes, and a­­­­­pplies transit-system-specific regression tree models that identify and prioritize transit system improvements through analysis and application of ridership, Census, routing and scheduling, and transit stop characteristic data. Regression trees identify and rank independent variables that split dependent variable datasets into meaningful subsets according to significant relationships with independent variable datasets, and regression tree models can be used to identify and prioritize transit system improvements. In this study, ridership datatypes are the dependent variables (i.e., boardings and alightings) and Census, routing and scheduling, and transit stop characteristic datatypes are the independent variables. Data associated with the …

The Effect Of Community Connectivity On Water And Sanitation Systems In Rural Panama, M.C. Moritz

Dissertations, Master's Theses and Master's Reports

The world has yet to realize universal access to water and sanitation. Various academic and professional fields provide frameworks for understanding water and sanitation access, but none directly consider the impact of community connectivity. Community connectivity refers to the infrastructures linking rural communities with urban centers. These infrastructures fall under the broad categories of transportation, energy, and telecommunication. This paper examines 23 rural Panamanian communities and compares connectivity measures with the functionality of the communities’ rural water and sanitation systems (RWSS). Community connectivity was evaluated with the Community Connectivity Analysis Tool (CCAT), while the water and sanitation systems were evaluated …

Investigating The Correlation Between Freeway Service Levels And Freeway Service Patrol Assists, Nora Chin

Master's Theses

The Bay Area Metropolitan Transportation Commission’s (MTC) Freeway Service Patrol’s highway motorist response service is reporting a reduction in their service levels. We analyze the relationship between the reduction in the Bay Area Freeway Service Patrol’s (FSP) motorist assists and changes in vehicle miles traveled (VMT), California Highway Patrol (CHP) reported incidents, and cover research on the impact of new and old vehicle fleet turnover. VMT and CHP incidents have differential effects on FSP assists. Although incidents occurring on freeways with high traffic flows tend to cause more congestion, the trend in local VMT along Bay Area freeway corridors does …

Using Archived Transit Data To Analyze The Effect Of Rainfall On Transit Performance Measures At The Route Level, Nicholas F. Bleich

Master's Theses

This study investigates the effect of rainfall on transit performance measures at the route level in the Puget Sound region of Washington State. Transit agencies are required to report certain performance metrics to the Federal Transit Administration (FTA), but performance measures can also be used to evaluate service and provide customers with information regarding the transit system. Using a three-year sample of archived automatic vehicle location (AVL) and hydrologic data the relationships between ridership, travel time, delay, and rainfall were investigated. The analysis of daily ridership and rainfall resulted in no statistically significant results, however, the results are supported by …

Low Income, Supermarket Accessibility, And The Transportation Network: A Multimodal Analysis Identifying Areas Of Poor Accessibility And Intervention Strategies In Indianapolis, Indiana, Andrea Leigh Bailey

Open Access Theses

The United States Department of Agriculture (USDA) Economic Research Service estimates that 23.5 million people live in food deserts, over half of which are considered low-income residents. Accurately defining a food desert is crucial as the designated areas can benefit from grant opportunities and funding priority. To qualify as an urban food desert, the USDA requires that at least 500 residents or one-third of the population live outside a one-mile buffer from a supermarket as well as have a median income of less than 80% of the area average or a poverty rate of greater than 20%. Approaches in the …

Accounting For The Short Term Substitution Effects Of Walking And Cycling In Sustainable Transportation, Daniel P. Piatkowski, Kevin J. Krizek, Susan L. Handy

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

The environmental benefits of bicycling and walking depend on the degree to which their use substitutes for car driving. Assuming that every walking and bicycling trip replaces a driving trip is likely to produce overestimates of the potential for such modes to reduce vehicle travel and city-scale greenhouse gas emissions. Measuring this ‘‘substitution effect’’ is not straightforward. There are many dimensions of the substitution effect, including trip type, substituting mode, extent, time horizon, and activity patterns. Previously used approaches to measure substitution include indirect inference and direct questioning. This study piloted an intercept survey using the direct questioning approach at …

The History Of The Trinity Highway: A Study In Transportation Dynamics, Richard Wilutus

Books and Other Publications

Although the primary focus of this thesis is a history of California 299--the Trinity Highway, I have studied the construction of that road in the context of the history of transportation between Weaverville and Humboldt Bay. The history of a transportation network is not only a history of connections between people and places but also, in this remote region, the vital link connecting wilderness with civilization.

Ever since the settlement of the Weaverville area in 1848, its residents have sought reliable transportation to Humboldt Bay's seaport and merchandise. During this period a road has connected these two places for less …
