Event Type: Seminar

Traffic crashes and accidents at intersections, roundabouts and roadway segments result from many complex factors, but
at a basic level, they are outcomes of the interactions among vehicles and other road users. Since few direct measurements
of these interactions are available, engineers and planners instead attempt to understand them by studying crashes and
accidents reports. As crashes account for a tiny fraction of safety conflicts, these reports fail to provide a full
understanding of what is happening at the points of accidents. This is especially true of crashes involving pedestrians and
bicycles, for which data are sparse, making it difficult to determine reliable patterns. In this talk we will present risk based
traffic safety models using multiple data streams, including near miss data, systemic data, historical traffic accidents, and
drivers’ naturalistic behavior data. We will also briefly discuss ongoing research at Rutgers on the development of
Plan4Saefty software, which is currently being used by the State of New Jersey for traffic safety analysis and planning.

Electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) have attracted worldwide attentions because of their capabilities to improve energy and environment sustainability. However, inconvenience of charging, high cost, short driving range, and safety concerns of the battery system have hindered the mass market penetration of EVs and PHEVs. This presentation will look at studies which address some of these issues with wireless charging technology.

This presentation will focus on wireless charging technology that helps eliminate the need of carrying cables and plugging in, and offer significant improvement in convenience and electric safety for EV and PHEV charging. Although Wireless Power Transmission (WPT) has been commercialized for consumer electronics and also investigated for EV wireless charging, the size, efficiency, and cost are key obstacles that prevent WPT from widely deployed. Our research in this area aims at novel designs that can considerably reduce size and cost while increase coupling coefficient and system efficiency.

After two years of study, two designs of the magnetic-resonance WPT chargers have been developed at UM-Dearborn. Vertically layered magnetic-resonance WPT charger instead of layering all components horizontally is proposed, where the components of the magnetic-resonance WPT charger are vertically layered. When compared to the horizontal design, the vertical design will be considerably thicker, requiring a larger space for positioning.

The investigators have presented detailed designs for major structures of the magnetic-resonance WPT charger. Laboratory prototypes have been made and 8kW power transfer has been achieved over 200mm distance with up to 96.5% DC-DC efficiency, with alignment tolerance of up to 300 mm. UM is working with Mia Motors and DENSO International to develop a prototype vehicle.

The rapid expansion of the U.S. biofuel industry diverts a large amount of farm land into energy feedstock production, and in turn affects food, energy and land market equilibria, as well as agricultural economic development in local areas. In this talk, we present Stackelberg-Nash game models that incorporate farmers’ decisions on land use and market choice into the biofuel manufacturers’ supply chain design problem. The models determine the optimal number and locations of biorefineries, the required prices for these refineries to compete for feedstock resources, as well as farmers’ land acquisition and production decisions. We also introduce government farmland use regulations that aim at balancing food and energy production and marginal land use, and a cap-and-trade implementation mechanism. Spatial market equilibrium is utilized to model the relationship between crop supply and demand and the associated price variations in local food markets. We develop solution approaches that transform the original discrete mathematical program with equilibrium constraints into a mixed integer quadratic programming problem, and explore adaptive decomposition methods based on Lagrangian and linear relaxations. The proposed methodologies are illustrated with an empirical case study of the Illinois State. The computation results reveal interesting insights into optimal land use strategies, government regulations, and supply chain design for sustainable development of the emerging "biofuel economy.”

Over the past 20 years the transportation engineering field has witnessed a data revolution—some might say that we have transitioned from a data “desert” to a data “ocean.” Join Prof. Robert Bertini as he traces aspects of his research career over this period and describes the ways in which this data “ocean” has inspired, enabled and influenced his work. We know that most transportation management, logistics, and operations systems, as well as intelligent transportation systems (ITS) applications are founded upon a data infrastructure, and sometimes these data are archived in a systematic manner. If managed properly, archived ITS data from sensors and mobile probes can provide a unique foundation for scientific discovery in the traffic and transportation field. Through careful processing and using innovative visualization techniques, transportation data can reveal fundamental traffic principles, behavior and phenomena, such as freeway merging at on-ramps and lane-drops and oscillations. Transport data may also be used to enable the optimization of the deployment of transportation resources, such as freeway sensors, traffic management applications or transit stops. Further, transport data, if analyzed carefully can provide the basis for conducting evaluations and assessments of transportation system congestion and performance, at different geographic levels, such as facility, corridor or region. Finally, the inception of a “connected” transportation environment with vehicles and infrastructure devices communicating at high frequency, we are moving to yet another level of transportation data availability. But numerous questions remain about who will own and manage these data, how will privacy be maintained and more. What does the future hold in the field of transportation enabled by an avalanche of high-resolution multimodal data? Also to be presented will be some approaches for meeting challenges and opportunities in the civil and environmental engineering field, which continues to be people-serving, relevant and critical for the future of our society. Finally some thoughts on teaching and civil and environmental engineering education will be discussed.

Against the backdrop of an ageing Japan, and as a countermeasure against the low birthrate phenomenon, the promotion of an environment that allows children, pregnant women, and parents of babies and young children to participate in out-of-home activities in a safe and comfortable manner is increasingly becoming more important. This study focuses on barriers encountered by parents with young children when conducting out-of-home daily activities. We conducted a web-based questionnaire survey on 1,000 women with young children living in the Kanto Region, including Tokyo Metropolitan Area. We found differences in their travel mode and frequency, and attitude towards barriers for out-of-home activity participation among living areas and individual/household characteristics such as working mother or not, numbers and years of children, years of raising child, household structures, etc.

Two analytical models are introduced for predicting the allocation to ports and transportation channels of containerized goods imported from Asia to North America. Assuming fixed distributions for container flow-times, the Long-Run Model heuristically solves a mixed integer non-linear program to determine the least-cost supply-chain strategies for importers. The Short-Run Model uses estimates of the flow times as a function of traffic volumes on fixed infrastructure to iteratively develop the best near-term strategies.

The models allocate imports to alternative ports and logistics channels so as to minimize total transportation and inventory costs for each importer. Alternative logistics channels include direct shipment of marine containers via truck or rail, and trans-loading cargoes in the hinterlands of the ports of entry from marine containers into domestic trailers or containers.

The models are calibrated on industrial data. Minimum volume requirements and capacities for ports and landside channels are considered. The results are analyzed, and are used to describe the mix of supply-chain strategies utilized by various types of importers and the consequent trends in import flows by port and landside channel. Policy recommendations for governments, transportation and logistics service providers, and importers are also provided. (Joint work with Rob Leachman at U.C. Berkeley)

Transportation involves human, infrastructure, vehicle, and environmental interactions and is therefore a very complicated system. Traditionally, transportation has been studied through classical methods, typically with ideal assumptions, limited data support, and poor computing resources. While the theories (such as traffic flow and driver behavior models) developed through these efforts provide valuable insights in understanding transportation-related issues, they are often ineffective in large-scale transportation system analysis with massive amount of data. Also, transportation activities have been found affecting public health, air quality, environmental sustainability, etc., but our understanding in these relationships has been trivial and far from complete.

With recent advances in sensing, networking, and computing technologies, more and more transportation-related data and computational resources become available. These new assets are likely to bring in new opportunities to understand transportation systems better and address those critical transportation issues in a faster, more accountable, and more cost-effective way. From big data to big discoveries and big decisions: what is the gap and what needs to be done? Clearly, a new theoretical framework is needed to integrate the quickly growing massive amount of data, typically from numerous sources of varying spatial and temporal characteristics, into the large-scale transportation problem solving and decision making processes. Efforts along this line are likely to form up a new subject area, namely e-science of transportation, in the years to come. The speaker will share his vision and pilot research in linking big data to big discoveries and big decisions through his talk.

Ever since the term “SCM”first emerged in 1982 by Keith Oliver, one of strategic consultants at BAH, it has been widely acknowledged that supply chain management could be used as a strategic differentiator in a global business environment. As the network of supply gets more complicated and dispersed, this trend becomes a normal phenomenon among many of the leading corporates. Under this environment, SCM is no more a simple and tactical principle that governs the operation of a corporate: rather, it has to be highlighted as somewhat novel concept which is directly related to the core value of an enterprise. Starting with a basic question about the true identity of the SCM, this presentation will redefine the meaning of SCM from corporate’s core value system. To this end, various business cases will be discussed to draw some significant implications that can be observed only when we look SCM from value perspectives.
