Book Description
Over the last few years, the local value of mobility and information in our society has grown tremendously. As the importance of Information and Communication Te- nologies (ICT) increases, we expect more changes in future mobility behavior. This includes not only mobility behavior for the single user, but also for the transportation of goods and infrastructure operators. It will also affect the regulation of resources and political decision-making. Both, data and mobility become more connected. To cope effectively with the anticipated changes, we must expand our focus and take current developments in both areas into account. The topic of the Lakeside Conference 2010, Data and Mobility – Transforming Information into Intelligent Traffic and Transportation Services, was chosen to underline the importance of information and mobility in transport and to offer an opportunity to discuss and question current activities in this sector. We will consider intermodal concepts and deployments in particular, where data transfer plays a major role, as this could help to reduce the current lack of infrastructure capacity (especially on roads and at airports and seaports). Using modern technologies, traffic mana- ment could become more sustainable and efficient. The Lakeside Conference is, again, organized by a consortium composed of the Lakeside Technology Park, the Austrian Transport Telematic Cluster, AustriaTech and the American Embassy in Austria.

Book Description
The core of Connected Vehicle (CV) safety applications lies in the increased driver situational awareness of potential hazards. A robust Human Machine Interface (HMI) not only communicates information beneficial to the safety of the drivers, but also safeguards against potential adverse impacts drivers may experience. This study acts in the furtherance of a user centered HMI design and User Experience (UX) for the Wyoming DOT CV Pilot’s end users, particularly, the equipped truck drivers. To achieve this objective, this study leverages a multi-pronged approach consisting of; 1) Drawing lessons from the state-of-the-art and the state-of the-practice relevant to HMI and UX design, 2) Evaluating the behavioral impacts of truck drivers’ exposure to the Pilot’s CV warnings under a controlled driving simulator environment, and 3) Conducting surveys with the Pilot’s stakeholders to inform the HMI and UX design enhancements. With this in view, this thesis brings together three distinct studies all acting in the same direction. The first two studies leverage a driving simulator experiment featuring twenty CV-equipped professional truck drivers, all recruited by the Wyoming DOT. These studies aimed at assessing the effects of exposure to the CV weather and work zone warnings on the behavior of the participants while navigating a work zone under reduced visibility. Adverse weather conditions were incorporated within the scenarios to simulate the frequent challenging weather conditions on I-80 in Wyoming. To this end, each participant drove two scenarios with replicate layout and driving and weather conditions, however, once with the HMI being deactivated (baseline scenario) and a second time with the HMI being activated to communicate the CV warnings (CV scenario). Throughout the experiment, vehicle dynamics data, eye glance data, and post-drive questionnaires were collected. The first study sought to assess the impacts of exposure to the CV warnings on the subjects’ driving behavior using vehicle dynamics data and post-drive questionnaires. Overall, findings from this study revealed that exposure to the CV weather and work zone warnings has promising safety benefits manifested in 1) The early and less aggressive braking responses observed in preparation of the adverse weather conditions, 2) The lower speed variability between the participants in the work zone advance warning area, 3) The early lane merge behavior ahead of the work zone lane closure, and 4) The high participants’ approval of the CV warnings in terms of ease of understanding and usefulness for the real-world application. Nonetheless, few participants may have experienced distraction brought about by the display of several CV work zone warnings. This was observed in the slight deterioration in the lane keeping behavior, in addition to the rankings of few subjects suggestive of potential distraction. The second study sought to quantify the effects of exposure to the Pilot’s CV weather and work zone warnings on the participants’ visual/ cognitive workload, in addition to measuring the introduced distraction. This was accomplished using eye tracking technology; a powerful tool to identify where and for how long a driver is looking within the visual scene. Overall, this study showed that 1) The display of the CV weather and work zone warnings induced glances to the HMI that are well within the typical range of in-vehicle devices, 2) The weather notifications did not induce significant visual or cognitive workloads demands to the truck drivers thanks to the little amount of information that was communicated on the HMI, in addition to the appropriate timing/driving environment at which the weather warnings were communicated, 3) Conversely, the CV work zone warnings induced significant visual/cognitive demand to the drivers, corroborating the findings from the previous study. This is likely due to the display of multiple small-sized work zone warnings on the cluttered HMI in a short window of time during demanding driving conditions. The last study sought to draw the key lessons learned from the previous work on HMI and UX design for the benefit of the Wyoming CV Pilot’ stakeholders and end users. These lessons contributed to the development of practice-ready recommendations being adopted by the Wyoming DOT for immediate and future implementation. All in all, these lessons address 1) The imperative need for CV warnings to prompt appropriate driver response, 2) Designing the HMI to support safe vehicle operation and minimal driver nuisance, and 3) Crafting a thoughtful UX built-around stakeholders’ needs. Key recommendations in this study include reducing the message flow rate from the Work Zone Warnings application to reduce the potential of real-life distracted driving and driver nuisance. This is in addition to improving the visibility of the warnings on the HMI, so that drivers can effectively perceive and extract information from the HMI in a timely fashion.

Book Description
There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.

Book Description
This book discusses the latest progresses and developments on complex systems research and intends to give an exposure to prospective readers about the theoretical and practical aspects of mathematical modelling, numerical simulation and agent-based modelling frameworks. The main purpose of this book is to emphasize a unified approach to complex systems analysis, which goes beyond to examine complicated phenomena of numerous real-life systems; this is done by investigating a huge number of components that interact with each other at different (microscopic and macroscopic) scales; new insights and emergent collective behaviours can evolve from the interactions between individual components and also with their environments. These tools and concepts permit us to better understand the patterns of various real-life systems and help us to comprehend the mechanisms behind which distinct factors shaping some complex systems phenomena being influenced. This book is published in conjunction with the International Workshop on Complex Systems Modelling & Simulation 2019 (CoSMoS 2019): IoT & Big Data Integration. This international event was held at the Universiti Sains Malaysia Main Campus, Penang, Malaysia, from 8 to 11 April 2019. This book appeals to readers interested in complex systems research and other related areas such as mathematical modelling, numerical simulation and agent-based modelling frameworks.
