Connected vehicles, also called smart vehicles or smart vehicles, could be described as vehicles which are equipped with Sophisticated conversation systems and sensors to connect with other vehicles, infrastructure, and the internet.
Development in batteries, electric motors and energy electronics have produced electric cars much more feasible than in the course of the 20th century.
Sustainable mobility is definitely the time period utilized to confer with transportation from an environmental or ecological frame of mind. In the long run, the goal for sustainable mobility will be to mitigate the use of abnormal gasoline use and lower emissions to ensure that our ecosystems can replenish themselves.
On the flip side, While some studies26,27 have delivered an Over-all overview on the SMT area, they generally perform static statistical analyses from the literature devoid of mapping the understanding composition or tracing the sphere’s dynamic growth trajectory. These kinds of insights are vital for helping researchers discover Main regions and make informed choices about upcoming exploration Instructions. Moreover, with the immediate expansion of the SMT subject and an exponential rise in publications lately (see Fig. 1a), the volume of papers reviewed in the above mentioned research is way more compact than the total number of publications currently available. Particularly in the put up-pandemic era, a wave of emerging systems which include autonomous driving28 and clever shipping29, together with modern travel modes like multimodal transport30, and carpooling31, are now being explored to ease website traffic congestion and strengthen travel performance, thereby advancing SMT improvement. These innovations are reshaping investigation tendencies and Instructions in the SMT industry. For that reason, it underscores the urgent have to have for an intensive reassessment of the academic landscape in SMT to stay abreast of these evolving dynamics.
The objective from the textbook is to coach engineering learners on present applications and plan levers that could be applied to incorporate rising transportation technologies in a sustainable, equitable, and economical method. The course is created for graduate transportation engineering, and city and regional organizing pupils. The undergraduate seniors should be able to take up the resources offered they have got already taken essential classes on transportation engineering and scheduling, together with site visitors engineering and highway style and design.

During this research, we proposed a brand new system to quantify Every single topic’s relative relevance and observe its evolution trend over time, consisting of the following a few techniques.
An alternate method of sourcing critical battery components becoming deliberated because of the Worldwide Seabed Authority is deep sea mining, however carmakers are usually not working with this as of 2023.[160]
Within the methods higher than, motion is furnished by a rotary electric motor. However, it is achievable to "unroll" the motor to travel right in opposition to a Unique matched track. These linear motors are used in maglev trains which float above the rails supported by magnetic levitation.
This info is then processed by onboard personal computers and transmitted to other vehicles or infrastructure to deliver precious insights and improve the All round driving knowledge.
Total, this paper features policymakers, researchers, and practitioners an academic landscape while in the SMT industry. It aids policymakers in formulating aligned methods, allows scholars to grasp exploration frontiers immediately, and supports practitioners in driving technological innovation. Nevertheless, this review has restrictions. By way of example, our Assessment generally depends over the WoS Main Assortment database. While this databases objectively and correctly signifies the field’s information structure, it inevitably overlooks critical publications that appreciably affect the field’s development, such as white papers. Therefore, future research should really include further info resources and publication forms to achieve a far more complete understanding, guaranteeing a thorough protection of all impactful information and knowledge during the SMT subject.
Furthermore, we constructed a co-citation network of references to identify The real key literature supporting the development of those preferred subjects. Determine four displays the most important connected element comprising the highest a thousand references with a minimum of ten citations and the highest co-citations counts. Each individual node signifies a reference, labeled with the initial writer’s name and the publication calendar year, and scaled by its amount of citations. Utilizing a modularity-based clustering algorithm35, we categorised all nodes into nine clusters based on their own co-citation strength. Subsequent content Assessment of references inside each cluster enabled vehicle electrification us to assign precise labels and detect the pattern of the top 3 most cited references in each cluster (see Supplementary Table five for specifics). These references cover a variety of subfields and align closely with the seven study topics. For example, references during the blue51,fifty two and green58 clusters align Together with the matters of Infrastructure and Accessibility, and Journey Habits, respectively. Co-citation Investigation discovered insights that were not apparent from the search phrase co-occurrence networks. Notably, quite a few SMT-related reports reference performs on bicycle-sharing and electric bicycles59,60 (i.e., red and light-weight red clusters), highlighting a escalating curiosity in these bicycle-primarily based shared mobility modes as a whole new analysis focus.
Sustainable mobility and sustainable transport has become outlined otherwise by various Formal businesses and entities throughout the world. As an illustration, the eu Union Council of Ministers of Transport defined that a sustainable transportation method will offer people and firms with entry to primary transportation demands although also preserving the health of human beings and our ecosystem.
