Contributions to sustainable urban transport : decision support for alternative mobility and logistics concepts

Increasing transport activities in cities are a substantial driver for congestion and pollution, influencing urban populations’ health and quality of life. These effects are consequences of ongoing urbanization in combination with rising individual demand for mobility, goods, and services. With the goal of increased environmental sustainability in urban areas, city authorities and politics aim for reduced traffic and minimized transport emissions. To support more efficient and sustainable urban transport, this cumulative dissertation focuses on alternative transport concepts. For this purpose, scientific methods and models of the interdisciplinary information systems domain combined with elements of operations research, transportation, and logistics are developed and investigated in multiple research contributions. Different transport concepts are examined in terms of optimization and acceptance to provide decision support for relevant stakeholders. In more detail, the overarching topic of urban transport in this dissertation is divided into the complexes urban mobility (part A) in terms of passenger transport and urban logistics (part B) with a focus on the delivery of goods and services. Within part A, approaches to carsharing optimization are presented at various planning levels. Furthermore, the user acceptance of ridepooling is investigated. Part B outlines several optimization models for alternative urban parcel and e-grocery delivery concepts by proposing different network structures and transport vehicles. Conducted surveys on intentional use of urban logistics concepts give valuable hints to providers and decision makers. The introduced approaches with their corresponding results provide target-oriented support to facilitate decision making based on quantitative data. Due to the continuous growth of urban transport, the relevance of decision support in this regard, but also the understanding of the key drivers for people to use certain services will further increase in the future. By providing decision support for urban mobility as well as urban logistics concepts, this dissertation contributes to enhanced economic, social, and environmental sustainability in urban areas

Increasing Access to Food: A Comprehensive Report on Food Supply Options

Access to food is one of the most important aspects of a healthy, sustainable community. Grocery stores and other suppliers can serve as an economic anchor to provide social benefits to communities. Unfortunately, many communities do not have convenient and/or affordable access to grocery items, particularly fresh produce. As part of Virginia Commonwealth University\u27s Fall 2019 graduate course on Urban Commercial Revitalization, class members researched 13 retail and other food access options, which are described in this report. Each chapter covers a food access option and provides basic information that will be useful to individuals, organizations, or government agencies that wish to attract and/or develop grocery operations in their communities

California FreshWorks: A Case Study Examining the Development and Implementation of FreshWorks

TCE commissioned a two-year evaluation of FreshWorks to better understand the impact of the program on fresh food access, as well as social and economic outcomes. The evaluation also sought to document the development and implementation of FreshWorks while identifying key lessons and insights. Given that FreshWorks is an early example of a state-level healthy food financing initiative, the evaluation offers an opportunity to inform the broader healthy food movement going forward.This case study focuses on the development and implementation of FreshWorks, as well as key challenges encountered and lessons learned during the program's first years of operation. The evaluation team conducted interviews with FreshWorks investors, advisors, and other stakeholders in order to collect qualitative data documenting the Fund's origins and implementation process. These interviews formed the basis for the findings presented herein

Food Access in Petersburg, Virginia: Final Report and Recommendations

The City of Petersburg has long suffered with issues of limited access to food and food insecurity. Food deserts, or areas underserved by retail food options, are prevalent throughout the City. As a result, the Robert Wood Johnson Foundation has ranked the city last of Virginia\u27s 133 counties in their annual health rankings. For the Fall 2019 semester, students from Virginia Commonwealth University\u27s L. Douglas Wilder School of Government and Public Affairs, through Dr. John Accordino\u27s Urban Commercial Revitalization course, focused on planning solutions to address food deserts in commercial areas, with the City of Petersburg being one of their clients. The class assessed the potential for commercial revitalization and made five recommendations

Analytical Modeling Framework to Assess the Economic and Environmental Impacts of Residential Deliveries, and Evaluate Sustainable Last-Mile Strategies

In the last decade, e‐commerce has grown substantially, increasing business‐to‐business, business‐to‐consumer, and consumer‐to‐consumer transactions. While this has brought prosperity for the e-retailers, the ever-increasing consumer demand has brought more trucks to the residential areas, bringing along externalities such as congestion, air and noise pollution, and energy consumption. To cope with this, different logistics strategies such as the introduction of micro-hubs, alternative delivery points, and use of cargo bikes and zero emission vehicles for the last mile have been introduced and, in some cases, implemented as well. This project, hence, aims to develop an analytical framework to model urban last mile delivery. In particular, this study will build upon the previously developed econometric behavior models that capture e-commerce demand. Then, based on continuous approximation techniques, the authors will model the last-mile delivery operations. And finally, using the cost-based sustainability assessment model (developed in this study), the authors will estimate the economic and environmental impacts of residential deliveries under different city logistics strategies.View the NCST Project Webpag

Online grocery retailing in Jordan: Future perspectives

Electronic commerce (e-Commerce) has been considered as the way of conducting business transactions online. The use of e-commerce technologies is widely accepted around the world since it offers organizations many opportunities to improve their performance. However, it is still skeptical that using this technology will come up with positive expectations. This study aimed at identifying the possible benefits and barriers that may affect the Jordanian grocery retailers’ decision to adopt this kind of technologies

Exploring Farm Business and Household Expenditure Patterns and Community Linkages

Farm operators are an integral part of some rural economies. The businesses they operate often hire seasonal and full-time employees and purchase goods and services from local farm implement dealers, input suppliers, and financial institutions. Farm household spending on food, furniture and appliances, trucks and automobiles, and a range of consumer goods also support local jobs and retail businesses in some communities. Based on the 2002 agricultural census and the 2004 Agricultural Resource Management Survey, this paper explores the linkages between farm household/ business expenditures and local communities.Farm business expenditures, farm household spending, employment, community linkage, Consumer/Household Economics, Farm Management, Community/Rural/Urban Development,

DSS (Decision Support Systems) in Indian Organised Retail Sector

Indian organised retail industry is poised for growth. Rapid state of change due to speedy technological developments, changing competitive positions, varying consumer behaviour as well as their expectations and liberalized regulatory environment is being observed in organized retailing. Information is crucial to plan and control profitable retail businesses and it can be an important source of competitive advantage so long as it is affordable and readily available. DSS (Decision Support Systems) which provide timely and accurate information can be viewed as an integrated entity providing management with the tools and information to assist their decision making. The study, exploratory in nature plans to adopt a case study approach to understand practices of organized retailers in grocery sector regarding applications of various DSS tools. Conceptual overview of DSS is undertaken by reviewing the literature. The study attempts to describe practices and usage of DSS in operational decisions in grocery sector and managerial issues in design and implementation of DSS. Comparision across national chain and local organized retailer in grocery sector reveals that national chain having implemented ERP partially are mostly using the same for majority of operational decisions like inventory management, CRM, campaign management. Two local players use spread sheets and in house software to make the above operational decisions. The benefits realized remain the same across the retailers. Prioritization as well as quantification of benefits was not communicated. The issues of coordination, integration with other systems in case of ERP usage, training were highlighted. Future outlook of DSS by the respondents portrayed a promising picture.
