Book Description
In 2007 Minnesota legislature approved a 5,000,000 project in order to demonstrate technologies which will allow for the future replacement of the gas tax with a fuel-neutral mileage charge. The Minnesota Department of Transportation (MnDOT) organized a study to examine the implementation and operation of a mileage based user fee program (MBUF), which might allow for the supplementation or replacement of traditional gas taxes. The primary objectives of the study were to: assess the feasibility of using consumer devices for implementing Connected Vehicle and MBUF applications. These applications included localized in-vehicle signing for improving safety, especially for rural areas, and the demonstration of the proposed Connected Vehicle approach for providing location-specific traveler information and collecting vehicle probe data. The study consisted of 500 voluntary participants, equipped with an in-vehicle system comprised of entirely commercially available components, primarily a smartphone using an application capable of tracking participant vehicle trips. Successfully meeting its primary objectives, the system was capable of assigning variable mileage fees determined by user location or time of day, as well as presenting in-vehicle safety notifications which had measureable effect on the participants driving habits. MnDOT contracted Science Applications International Corporation (SAIC) to perform research for the project and an evaluation of its findings. This document is the final report from SAIC, providing a summary of the study, its findings and an evaluation of the project as a whole.

Book Description
The connected vehicle is an emerging technology aimed at deploying and developing a fully connected transportation system which allows the vehicles to dynamically transmit messages between the vehicles (V2V), infrastructure (V2I), Cloud (V2C) and everything (V2X). The connected vehicles can provide an unprecedented amount of data even in the traffic network with a low market penetration rate, which can provide new solutions to transportation issues. This study focuses on micromodeling and quantitatively assessing the potential benefits of the connected vehicles on safety, mobility, and energy efficiency perspectives. In this dissertation, we proposed deep-learning based systems to solve different transportation problems under the environment of connected vehicles. The crash risk prediction system can identify crash-prone intersections and guide the deployment of safety measures to prevent potential crashes. The pothole detection system provides a cost-effective strategy to map the road conditions, which will be beneficial to road maintenance especially when municipal budgets are limited. The slippery condition surveillance system achieves real-time monitoring of pavement slippery conditions impacted by adverse weather and promotes cautious driving behaviors. The adaptive traffic signal control system provides an adaptive, efficient and optimized traffic signal control agent, which can reduce vehicle delay and emissions, improve mobility and energy efficiency. Overall, connected vehicle technology shows great potential in the field of transportation. The safety, mobility and energy efficiency will be further improved with the widespread deployment of connected vehicles and increase of market penetration rate, which is achievable in the near future.

Book Description
Connected Vehicles (CVs) has the potential to serve as a valuable source of traffic data in some transportation research areas from traffic state monitoring to transportation management and control strategies, due to the low cost, wide coverage, and relative high accuracy. CV technology also enables a variety of CV-based applications which present an opportunity to provide vehicles and drivers with situational awareness and improve upon the limited behaviors of conventional vehicles. Increasing efforts in the development and deployment of CV-enabled applications are ongoing to improve traffic safety, mobility, environmental sustainability, efficiency, and driving comfort. CVs have been analyzed separately for safety, mobility, and environmental sustainability (SME), however, very few studies evaluate these three performance measures holistically. There are important co-benefits and tradeoffs among SME when evaluating impacts CVs bring.

Book Description
An intelligent transportation system (ITS) offers considerable opportunities for increasing the safety, efficiency, and predictability of traffic flow and reducing vehicle emissions. Sensors (or detectors) enable the effective gathering of arterial and controlled-access highway information in support of automatic incident detection, active transportation and demand management, traffic-adaptive signal control, and ramp and freeway metering and dispatching of emergency response providers. As traffic flow sensors are integrated with big data sources such as connected and cooperative vehicles, and cell phones and other Bluetooth-enabled devices, more accurate and timely traffic flow information can be obtained. The book examines the roles of traffic management centers that serve cities, counties, and other regions, and the collocation issues that ensue when multiple agencies share the same space. It describes sensor applications and data requirements for several ITS strategies; sensor technologies; sensor installation, initialization, and field-testing procedures; and alternate sources of traffic flow data. The book addresses concerns related to the introduction of automated and connected vehicles, and the benefits that systems engineering and national ITS architectures in the US, Europe, Japan, and elsewhere bring to ITS. Sensor and data fusion benefits to traffic management are described, while the Bayesian and Dempster–Shafer approaches to data fusion are discussed in more detail. ITS Sensors and Architectures for Traffic Management and Connected Vehicles suits the needs of personnel in transportation institutes and highway agencies, and students in undergraduate or graduate transportation engineering courses.

Book Description
This book highlights the current challenges for engineers involved in product development and the associated changes in procedure they make necessary. Methods for systematically analyzing the requirements for safety and security mechanisms are described using examples of how they are implemented in software and hardware, and how their effectiveness can be demonstrated in terms of functional and design safety are discussed. Given today’s new E-mobility and automated driving approaches, new challenges are arising and further issues concerning “Road Vehicle Safety” and “Road Traffic Safety” have to be resolved. To address the growing complexity of vehicle functions, as well as the increasing need to accommodate interdisciplinary project teams, previous development approaches now have to be reconsidered, and system engineering approaches and proven management systems need to be supplemented or wholly redefined. The book presents a continuous system development process, starting with the basic requirements of quality management and continuing until the release of a vehicle and its components for road use. Attention is paid to the necessary definition of the respective development item, the threat-, hazard- and risk analysis, safety concepts and their relation to architecture development, while the book also addresses the aspects of product realization in mechanics, electronics and software as well as for subsequent testing, verification, integration and validation phases. In November 2011, requirements for the Functional Safety (FuSa) of road vehicles were first published in ISO 26262. The processes and methods described here are intended to show developers how vehicle systems can be implemented according to ISO 26262, so that their compliance with the relevant standards can be demonstrated as part of a safety case, including audits, reviews and assessments.

Book Description
A call to redefine mobility so that it is connected, heterogeneous, intelligent, and personalized, as well as sustainable, adaptable, and city-friendly. The twentieth century was the century of the automobile; the twenty-first will see mobility dramatically re-envisioned. Automobiles altered cityscapes, boosted economies, and made personal mobility efficient and convenient for many. We had a century-long love affair with the car. But today, people are more attached to their smartphones than their cars. Cars are not always the quickest mode of travel in cities; and emissions from the rapidly growing number of cars threaten the planet. This book, by three experts from industry and academia, envisions a new world of mobility that is connected, heterogeneous, intelligent, and personalized (the CHIP architecture). The authors describe the changes that are coming. City administrators are shifting from designing cities for cars to designing cities for people. Nations and cities will increasingly employ targeted user fees and offer subsidies to nudge consumers toward more sustainable modes. The sharing economy is coaxing many consumers to shift from being owners of assets to being users of services. The auto industry is responding with connected cars that double as virtual travel assistants and by introducing autonomous driving. The CHIP architecture embodies an integrated, multimode mobility system that builds on ubiquitous connectivity, electrified and autonomous vehicles, and a marketplace open to innovation and entrepreneurship. Consumers will exercise choice on the basis of user experience and efficiency, aided by “intelligent advisors,” accessible through their mobile devices. An innovative mobility architecture reconfigured for this century is a social and economic necessity; this book charts a course for achieving it.
