Abstract: Decision makers recognize that traffic forecasts are sometimes based on assumptions that may not be realized. They should be provided with tools that can help them to evaluate and select robust projects, no matter which future scenario materializes. There is a need to assess the risk of development occurring or not occurring, or development occurring at one location rather than another. Due to uncertainties in forecasting future transportation facilities, project evaluation procedures should be flexible enough to accommodate changing outcomes as they develop. This book develops a procedure based on Robustness Analysis techniques and uses an illustrative example in demonstrating the use of the methodology in project selection as it pertains to urban transportation planning. It has an advantage of making planning decisions more flexible by accommodating possible future surprises and minimizing the uncertainties of using the results of travel demand models. Robust projects will always perform better for a variety range of different future scenarios. Such projects are expected to perform well even if the assumptions made at the planning horizon will not well be met in the future.

Abstract: Uncertainty and lack of flexibility have been major problems facing decision makers in urban transportation planning when it comes to making a decision on project selection. The primary objective of this paper is to demonstrate the use of robustness analysis methodology in urban transportation planning as a decision aiding tool. An illustrative example is used whereby a set of various transportation system alternatives and growth scenario plans are developed and a travel demand modeling is run using the traditional four-step modeling. However, any other travel demand modeling method can be used as well. Robustness analysis methodology is used in developing the robustness scores for each scenario plan formulated and the total score for all road links in the network are determined. The volume-to-capacity ratios (v/c-ratios) are utilized as performance measures to generate the robustness scores. The robustness analysis has an advantage of making the urban transportation planning decisions more flexible by accommodating possible future surprises and minimizing the uncertainties of using the results of travel demand models. The main assumption is that robust projects will always perform better for a variety range of different future scenarios. Such projects are expected to perform well even if the assumptions made at the planning horizon will not well be met in the future. This paper demonstrates that robustness analysis is a simple tool and yet powerful for aiding in making sound decisions for urban transportation planning by using the results of the travel demand simulations. In addition, robustness analysis results can be used to highlight segments which will most likely affect the network performance reliability of a variety of anticipated future scenarios under normal projected travel demands.

Abstract: According to the Centers for Disease Control and Prevention, road crashes are one of the major causes of morbidity and mortality in the United States. The Healthy People 2020 has indicated that accidents are a major public health issue. Most motor-vehicle related events resulting in injury, disability, or death are predictable and preventable. Injuries are the leading cause of death for Americans aged 1 to 44 years and a leading cause of disability for all ages, regardless of sex, race/ethnicity, or socioeconomic status. Although motorcycles represent approximately 3% of all registered vehicles in the United States, motorcycling accounts for more than 13% of highway traffic fatalities. While fatalities normally represent a small percent of other motor vehicle occupants, fatalities can be as high as 40% for the motorcyclists when involved in accidents (or traffic crashes as typically referred to by transportation safety professionals). Motorcyclists are more vulnerable in crashes due to their lack of protection like enclosed vehicles do to motor vehicle occupants, so they are more likely to be severely injured or killed. Therefore, there is a motivation among stakeholders to decrease the injury severity of motorcyclists. A clear understanding of the factors influencing injury severity levels due to motorcycle crashes and the related evidence prevention strategies is of paramount importance. When examining a topic of motorcycle injury severity, it is important to keep into consideration of different issues that include the definition and concept of injury severity, trends in motorcycle crashes, motorcycle-related policies and laws, knowledge of risk and protective factors. The main purpose of this chapter is to discuss the risk factors and protective factors related to injury severity of motorcycle crashes in the US. Important aspects related to motorcycle crashes’ injury severity such as methodological challenges related to conceptual clarity and measurement are discussed. In addition, implications for education, research, practice and policy including laws and enforcement are highlighted so that the overall motorcycle safety situation could be improved.

Abstract: This chapter focuses on emerging delivery logistics and mobility services under the influence of advanced technologies in support of connected and automated transportation. Emerging technologies lead to the trend of transforming transportation into a service, sometimes referred to as smart mobility, which will potentially lead to a shift in the desire of individuals to own their vehicles as the shared mode of transportation. As the planning and delivery process of goods transportation in a supply chain, logistics are associated with all activities in the supply chain, which will be greatly influenced by the trend of automation by using unmanned delivery systems. As technologies such as smartphones, advanced computing, and wireless technologies, as well as Internet of Things have been rapidly evolving, some innovative ideas have been inspired with an attempt to provide efficient and safe transportation services by leveraging such emerging technologies. As a result, new mobility concepts and available solutions will appear in the models of on-demand mobility services to services providing convenient and flexible transportation alternatives. 

Abstract: This chapter provides an overview of three major components of future emerging sustainable mobility modes and services, namely, shared vehicle services, shared bicycle services, and first mile/last mile solutions to reinforce public transportation services. To facilitate a comprehensive understanding of these components, their fundamental characteristics and functions, their associated engineering and planning factors or issues, and the impacts of automation technologies on the future of mobility services, as well as innovation strategies are the focus of the chapter. 

Abstract: The purpose of this systematic review is to assess whether installation of cable median barriers (CMBs) in some stretches of freeways in different states have been effective in preventing cross median crashes (CMCs) and related casualties in the United States. As the CMBs get increasingly installed on highways, they have been taunted as the preferred median barriers due to their combination of lower costs of installation compared to other types of barriers such as concrete barriers and their effectiveness in their intended use, i.e.,  providing median crossover protection by preventing cross median crashes. Several state departments of transportation (DOTs) have been installing CMBs for more than 15 years and some states have evaluated the performance of median cable barriers installed on their freeways. This study evaluated safety evaluation studies from 12 states that have performed the effectiveness studies of CMBs. Ten of these studies were before-after studies and nine of them showed effectiveness of CMBs. Reductions in outcomes across studies ranged from 24% to 93% for fatal and serious injury cross-median crashes and 50% to 91% for total cross-median crashes. However, increasing in outcomes ranged from 18% to 163% for possible injury and property damage only crashes of vehicles that primarily collided with the barriers but did not cross-over to the opposing lanes. Cable barriers have proved to be a valuable safety engineering tool effective in reducing fatalities and serious injuries due to crossover crashes on the states’ most heavily traveled roads

Abstract: Fatherhood among African immigrant families who are not descendants of the U.S. Tran-Atlantic slave trade has received little attention in the literature. Drawing from the literature on African immigration studies, we bring to light the “dad” role in describing fatherhood in parenting and nurturing the African-born immigrant son. Specifically, we discuss the acculturative risks and protective factors influencing the father-son family subsystem within the larger socio-ecological environment. Implications for a multilevel approach is provided to facilitate a comprehensive understanding of father-son relationships at multiple levels of influence that can stem from various aspects of individual well-being, father-son interactions, family dynamics, and school and community interactions.
