Employer shuttle systems in Connecticut and New Jersey are reviewed. The planning processes underlying system development, the approach used to determine potential markets for employer shuttle services, and service design principles are outlined, and system performance is evaluated. Several case studies are presented, and the requirements for a successful shuttle program are identified as reliable line-haul transit, a direct route to employer concentrations located not more than 20 min from the line-haul transit, a seamless transfer, a reasonable fare structure, employer and public interest and support, and an effective marketing program.

In-vehicle noise is composed of a variety of tonal (frequency-related) components and the tonal components play an important role in the improvement of sound quality for interior vehicle noise. Among them, gear whine noise is the key contributor to total in-vehicle noise and gain a lot of researchers interest. Through their effort, thespl (dBA)is relatively low. However, customers still perceive the tonal components and complain about the vehicle quality. Therefore a better understanding of how tonal components are perceived is necessary for automotive gear transmission designers. In this study, firstly, gear dynamic behavior is briefly introduced to get the gear noise spectrum. Secondly, human hearing mechanism to different tonal components is summed. Then loudness case studies are conducted. Finally, some basic design principles of controlling gear whine noise are proposed based on the results.

The Way

<p>Can we establish the guidelines that make our designs into a success? Is there something like the Golden Ratio for shaping the curve? The Golden Ratio is a common mathematical ratio found in nature, which can be used to create pleasing, organic-looking compositions. This is used for the overall shape and proportions in bridge design. In our practice and in modern-day bridge design we see more and more curved bridges.</p><p>Especially with the rise of parametric design a whole world opened up for (more) complex curved designs. Curviness (either vertical, horizontal or both) is not just a nice aesthetic feature. We encounter design principles that need to be taken into account to get to the ultimate elegancy that we thrive for in our bridge design.</p><p>In our practice, shaping the curve of a bridge is a recurrent topic in the design process – from concept to realisation. From the forming of the (3D) <i>alignment, </i>it’s about how curves fluidly connect. It’s all about the radius, diameter, arcs, splines, offsets and the way to connect with tangents and sinusoids. This is best shown by the Lucky Knot and the Zaligebrug by NEXT architects. We also experienced the difficulties during construction phase and learned to control dealing with the unexpected.</p><p>With a series of case studies from our own bridges we show the importance of precision in shaping curves to make a design that is both natural and understandable to the eye of the user. If done right, curves seem logic and right; but if done improperly, it ends up as a disaster.</p>

Poetic Imagination

Recent societal critiques charge that the pervasiveness and ubiquity of screen-based technologies place the emotional, social, and cognitive development of their users at stake. Many of these critiques suffer, however, from a sensational and moralistic formulation. To move forward ethical investigation into sophisticated inquiry this essay closely examines one screenworld technology, videogames, with an aim of (a) categorizing videogames’ active and performative features and (b) assessing how these features present themselves during gameplay as compatible, incompatible, and antithetical to our humanistic needs. These needs form a value system termed the Humanistic Ethos which is further articulated into measurable characteristics along four dimensions—the Poetic Imagination, Dialogic Relations, Systemic Thinking, and Existential Vigor. A survey of videogames along with two case studies develop these dimensions within their technical, social, and personal contexts revealing the delicate interplay between designer, game and player. Design principles compatible with the Humanistic Ethos are discussed. Limitations and future directions are also considered.

Present Experimental Evidence

In this chapter we discuss a variety of topics relating to speech-based user interfaces for use in an automotive environment. We begin by presenting a number of design principles for the design of such interfaces, derived from several decades of combined experience in the development and evaluation of spoken user interfaces (UI) for automobiles, along with three case studies of current automotive navigation interfaces. Finally, we present a new model for speech-based user interfaces in automotive environments that recasts the goal of the UI from supporting the navigation among and selection from multiple states to that of selecting the desired command from a short list. We also present experimental evidence that UIs based on this approach can impose significantly lower cognitive load on a driver than conventional UIs.
