The convergence of mechanical, electrical, and advanced ICT technologies, driven by artificial intelligence and 5G vehicle-to-everything (5G-V2X) connectivity, will help to develop high-performance autonomous driving vehicles and services that are usable and convenient for self-driving passengers. Despite widespread research on self-driving, user acceptance remains an essential part of successful market penetration; this forms the motivation behind studies on human factors associated with autonomous shuttle services. We address this by providing a comfortable driving experience while not compromising safety. We focus on the accelerations and jerks of vehicles to reduce the risk of motion sickness and to improve the driving experience for passengers. Furthermore, this study proposes a time-optimal velocity planning method for guaranteeing comfort criteria when an explicit reference path is given. The overall controller and planning method were verified using real-time, software-in-the-loop (SIL) environments for a real-time vehicle dynamics simulation; the performance was then compared with a typical planning approach. The proposed optimized planning shows a relatively better performance and enables a comfortable passenger experience in a self-driving shuttle bus according to the recommended criteria.
Policy support platforms like the Feed-in Tariff and the Renewable Portfolio Standard have been very successful in accelerating renewable energy development around the world. Nonetheless, the sustained and consistent transition to a renewable energy future required, e.g., to avoid further climate change, continues to elude societies. To achieve substantial energy transformation, reconsideration of the finance-policy-market interaction is required and is contemplated here by positioning the build-out of a particular renewable energy technology, photovoltaic (PV) energy, as a commitment to infrastructure-scale development. A so-called 'solar city' strategy is analyzed in which large-scale deployment of PV throughout the urban fabric essentially constructs an urban renewable energy power plant by utilizing the vast rooftop real estate available in all cities. The article explores a capital market strategy for practical implementation of urban PV in six case study cities-Amsterdam, London, Munich, New York City, Seoul, and Tokyo. This study demonstrates the substantial potential of the solar city concept in each location and outlines a financing strategy to realize the potential.Restructuring the urban energy infrastructure has been identified as a key element in strategies to address climate and sustainability challenges. [41][42][43][44][45] Additionally, due to the vacuum left by unproductive international negotiations on climate change, energy-focused climate Advanced Review wires.wiley.com/wene 1 The following city area inputs were used: Amsterdam (165 km 2 ), London (321 km 2 ), NYC (789 km 2 ), Seoul (605 km 2 ), and Tokyo (623 km 2 ).
Previous research suggests that the potential for city‐scale photovoltaic (PV) applications is substantial across the globe. Successful implementation of ‘solar city’ options will depend on the strategic application of finance mechanisms, solar energy soft cost policies, and other policy tools, as well as the grid price of electricity. Capital markets recently have embraced the roll‐out of new financial instruments, including ‘green bonds,’ which could be incorporated into solar city project design to attract large investments at a low cost. A multivariate analysis method is employed to consider solar city possibilities for six cities: Amsterdam, London, Munich, New York, Seoul, and Tokyo. A Monte Carlo simulation is conducted to capture the probabilistic nature of uncertainties in the parameters and their relative importance to the financial viability of a solar city project. The analysis finds that solar city implementation strategies can be practical under a broad range of circumstances. WIREs Energy Environ 2017, 6:e241. doi: 10.1002/wene.241

Transformation of the urban energy metabolism is possible when sustainable energy is positioned as an infrastructure‐scale tool. A review of urban energy planning research is complemented by an examination of assessment methods in use to gauge the feasibility of planning sustainable energy as a new infrastructure to power cities. A case study analysis of the city of Daejeon is offered to operationalize this planning strategy. In particular, the integrated application of the “savings city” and “solar city” concepts where, respectively, citywide deployment of energy efficiency and rooftop photovoltaic energy systems is envisioned at a large‐scale, is explored for Daejeon through the innovative use of geospatial assessment methods and a visualization tool that can guide urban policy. This assessment and its visualization illustrates not only grid energy use divisions throughout the city but also reveals possible energy planning trajectories in pursuit of positioning sustainable energy as urban infrastructure. The assessment finds that cities like Daejeon could fulfill over half of their electricity service needs through in‐city deployment of sustainable energy at the infrastructure‐scale. Cities that embark on this “sustainable city” trajectory essentially reform the lived experience of “the city” and reshape the city‐energy relationship.
