Rethinking the Way We Move Beyond COVID-19WP-00126/11/2020
As the world grapples to combat the spread of COVID-19, our city streets have nearly emptied. Unprecedented community mitigation interventions have been applied in efforts to “flatten the curve” and slow the transmission of the virus. Social distancing measures have dramatically altered our daily behavior; notably, in the ways we do or do not move. This report seeks to identify emerging trends in urban mobility and road safety in respect to COVID-19. This is followed by a discussion of how we could shape our mobility future as communities begin to reopen.

Autonomy's ‘Pirouetting’ Future20AVEP01_061/1/2020
Protean Electric's novel 360-degree steering and in-wheel drive systems add new potential for urban mobility. Designing and engineering a 360-degree steering capability for a production electric autonomous road vehicle's four wheels is no mean achievement. But Protean Electric also combines this pirouetting capability with an in-wheel electric motor, “innovative” suspension and pneumatic ride height control into an all-in-one package. Its adroit wheel-at-each-corner module, called Protean360+, is designed initially for next-generation urban mobility pods. But it could also be applied to a wide variety of other autonomous vehicles. Development of the 360-degree capability began in early 2018. It is the latest element to be added to the company's ProteanDrive in-wheel system, on which work started more than a 10 years ago to specifically meet emerging needs for radical new urban vehicle technology combined with autonomous transport visions. These include autonomous passenger cars, light-duty commercial vehicles and other future mobility solutions.

Data Privacy in the Emerging Connected Mobility Services: Architecture, Use Cases, Privacy Risks, and Countermeasures11-02-01-000410/14/2019
The rapid development of connected and automated vehicle technologies together with cloud-based mobility services is transforming the transportation industry. As a result, huge amounts of consumer data are being collected and utilized to provide personalized mobility services. Using big data poses serious challenges to data privacy. To that end, the risks of privacy leakage are amplified by data aggregations from multiple sources and exchanging data with third-party service providers, in face of the recent advances in data analytics. This article provides a review of the connected vehicle landscape from case studies, system characteristics, and dataflows. It also identifies potential challenges and countermeasures.

ZF's Tech Portfolio is Ready for Level 4 Autonomy19AVEP09_119/1/2019
Well aware of the relentless hype that comes with automated driving development, ZF's autonomy boss knows cost will be crucial-and customer persuasion required. “We are constantly asking this question: Who is the customer likely to buy an SAE Level 4 autonomous vehicle in the consumer passenger market?” This is one of the key queries that drives the thinking of Torsten Gollewski, head of autonomous mobility systems at ZF. The global Tier 1 is playing a crucial role in enabling the next generation of mobility. A technology pragmatist, Gollewski is well aware of the hype that surrounds autonomous vehicles (AVs). There's a commonly held belief outside the industry that all vehicles will soon be automated and electric.

The Distributed Simulation of Intelligent Terrain Exploration2018-01-191510/30/2018
In this study we consider the coordinated exploration of an unfamiliar Martian landscape by a swarm of small autonomous rovers, called Swarmies, simulated in a distributed setting. With a sustainable program of return missions to and from Mars in mind, the goal of said exploration is to efficiently prospect the terrain for water meant to be gathered and then utilized in the production of rocket fuel. The rovers are tasked with relaying relevant data to a home base that is responsible for maintaining a mining schedule for an arbitrarily large group of rovers extracting water-rich regolith. For this reason, it is crucial that the participants maintain a wireless connection with one another and with the base throughout the entire process. We describe the architecture of our simulation which is composed of HLA-compliant components that are visualized via the Distributed Observer Network tool developed by NASA. Additionally, a well-known terrain exploration algorithm, which takes the constraint of a mobile ad hoc network into account, is summarized and then extended by using a trainable genetic algorithm to determine the movement of the robotic swarm at every time step of the simulation. The integration of this extended algorithm into the distributed simulation is discussed and the empirical results of a comparison between the original and extended versions are given. Our results suggest that the genetic algorithm serves as a useful aid in the simulation of coordinated exploration and provides a layer of flexibility, offered by the trainable parameters its fitness function depends upon, that allows for the introduction of new constraints while maintaining compatibility with dynamic shifts in priority.

Ideas for multi-modal mobility18AUTP10_0410/1/2018
Silicon Valley often gets credit for ideas that have been percolating elsewhere for a long time. Great ideas that are not yet fully refined and need a tweak or two to make them viable. Case in point: micro mobility. Last March, I was in San Jose for the Nvidia GPU Technology Conference when a flock of Bird electric scooters magically appeared all over the sidewalks of downtown. Within days, there were thousands more in San Francisco and other cities from Bird, Lime and several other startups. Some critics of this sudden flood called it “scootermaggeddon.”

The Impact of the Autonomous Vehicle in Society and in the Urban Mobility in the City of São Paulo2017-36-038611/7/2017
The safety, reliability and efficiency in the progress of the autonomous vehicle have increased in recent years. In parallel, companies in the segment of people transportation, either individually or shared, took the world leadership using smartphone app into a new concept of urban mobility with conventional vehicles with drivers, starting consequently a change of habit of the population, and defying the laws of local transport. These services for urban mobility are related as tendencies of driving forces in the face of the relevance of the limitations of resources, population density, greater awareness toward the environment and traffic congestion. The acquisition of the “own vehicle” as currently, conceived and successful by Alfred Sloan in the 1920s, has become a question for future generations. This study shows that the provision of a more secure service, reliable, and efficient, will enable a significant reduction in total cost of ownership to the increasingly sophisticated and highly informed generation Z, who continually seeks to optimize its resources, availability and quality of life in real time. It also shows how the autonomous vehicles will transform urban mobility in the next 20 years and the impact generated in the city of São Paulo, the largest city in Latin America and with more than 12 million inhabitants.

Cybercars for Sustainable Urban Mobility - A European Collaborative Approach2010-01-234510/19/2010
We know that the existing urban transport systems based on the private vehicle (necessarily relying mostly on fossil fuels) are not sustainable in terms of energy and land needs. On the other hand, public transportation systems are also not very efficient and do not provide a good service anywhere and anytime. Over the last twenty years, a new concept has emerged through strong cooperation between researchers, automotive companies, suppliers and transit operators. It is the concept of co-modal systems. This means well-designed systems that will combine the use of various transportation modes and in particular the individual vehicles and the mass transit systems. A key element of such a system is the Cybernetic Transportation Systems (CTS), which are based on fully automated urban vehicles. This paper will present these CTS and how they have emerged through a European collaborative approach. These environmental-friendly novel systems offer far-reaching solutions that will drastically mitigate or solve the problems that we encounter in current urban transportation systems. They will yield much more effective organization of the urban mobility, with a more rational use of motorized traffic; less congestion, pollution noise and CO₂ emissions and better accessibility and safety. The result will be a higher quality of living, an enhanced integration with the spatial and also societal development and advancement towards sustainability.
