This paper presents a review of the different models developed for the taxicab problem. The presented models are grouped in two categories, aggregated and equilibrium models. Each model is analyzed from different points of view, such as market organization, operational organization and regulation issues. Conclusions extracted by authors are presented, listed and compared, analyzing each affirmation in terms of market regulation and organization. Finally, a state of the practice is presented, analyzing the configuration of the taxi market regulations along the world, linking the conclusions obtained by the authors with the real market situations

The ongoing energy transition has caused a paradigm shift in the architecture of power systems, increasing their sustainability with the installation of renewable energy sources (RES). In most cases, the efficient utilization of renewable energy requires the employment of energy storage systems (ESSs), such as batteries and hydro-pumped storage systems. The need for ESS becomes more apparent when it comes to non-interconnected power systems, where the incorporation of stochastic renewables, such as photovoltaics (PV) systems, may more frequently reduce certain power quality indicators or lead to curtailments. The purpose of this review paper is to present the predominant core technologies related to ESSs, along with their technical and life cycle analysis and the range of ancillary services that they can provide to non-interconnected power systems. Also, it aims to provide a detailed description of existing installations, or combinations of installations, in non-interconnected European islands. Therefore, it provides an overview and maps the current status of storage solutions that enhance the sustainable environmentally friendly operation of autonomous systems.

Advancements in the field of telematics have empowered the development of connected vehicle (CV) applications, which optimize the energy and traffic efficiency of vehicular traffic. Over the past decade, various research groups have proposed different methodologies for the implementation of dynamic eco-driving near signalized intersections. This paper reviews the proposed methodologies laying emphasis on the control logic, optimization objectives, assumptions, and constraints of these models. The strengths and limitations of existing dynamic eco-driving models are discussed, and future research directions are proposed in relation to the opportunities emerging in the field of transportation and the technological barriers that may exist. Further, the methodologies implemented for the assessment of the impacts of dynamic eco-driving are critically reviewed.
