Smart Mobility Strategy in Korea on Sustainability, Safety and Efficiency Toward 2025

Abstract: Surface transportation systems encounter strong demand for improved safety, reduced congestion and enhanced throughputs which lead to continuous innovation on vehicular technologies, while meeting the need for a sustainable energy future. Applying vehicular connectivity and automated vehicle technologies to deliver a smart mobility system in view of safety, throughputs and required conveniences, will interface a core activity of intelligent transportation system (ITS) strategic planning and implementation. So far, the power source transition to electrification, either battery- or fuel cell-based, has not been fully considered globally within the future ITS strategy. Consequently a strategy for the smart mobility has been developed to 2025 at the Korean national level, of which the core approaches are described in this paper. In addition to the review on various test-bed developments and implementations in Europe, the US, and Japan, the strategic planning on technology roadmap and test-bed application by identifying and prioritizing the future road transport demand are discussed, emphasizing vehicular connectivity and electrification.

Complex network theoretical analysis on information dissemination over vehicular networks

Abstract: How to enhance the communication efficiency and quality on vehicular networks is one critical important issue. While with the larger and larger scale of vehicular networks in dense cities, the real-world datasets show that the vehicular networks essentially belong to the complex network model. Meanwhile, the extensive research on complex networks has shown that the complex network theory can both provide an accurate network illustration model and further make great contributions to the network design, optimization and management. In this paper, we start with analyzing characteristics of a taxi GPS dataset and then establishing the vehicular-to-infrastructure, vehicle-to-vehicle and the hybrid communication model, respectively. Moreover, we propose a clustering algorithm for station selection, a traffic allocation optimization model and an information source selection model based on the communication performances and complex network theory.

Vehicular movement patterns: A prediction-based route discovery technique for VANETs

Abstract: Applications for Vehicular Ad-hoc Networks (VANETs) have been surfacing every day as with any new network architecture. One of the many challenges that have been addressed is the use of probabilistic models and behavioral patterns to predict routes vehicles undertake in a certain geographical area. This challenge, once overcome, could prove to be very beneficial for problems such as vehicular traffic control. This paper proposes a predictive technique based on sequential patterns and two mechanisms used to prepare data for this technique, as well as some performance evaluation for these mechanisms to determine the most feasible choice in terms of communication overhead. From the experiments, it can be noticed that one of the data collecting schemes has proven to be more efficient when travelling at different speeds.

Cyber security standards and issues in V2X communications for Internet of Vehicles

Abstract: Significant developments have taken place over the past few years in the area of vehicular communication systems in the ITS environment. It is vital that, in these environments, security is considered in design and implementation since compromised vulnerabilities in one vehicle can be propagated to other vehicles, especially given that V2X communication is through an ad-hoc type network. Recently, many standardisation organisations have been working on creating international standards related to vehicular communication security and the so-called Internet of Vehicles (IoV). This paper presents a discussion of current V2X communications cyber security issues and standardisation approaches being considered by standardisation bodies such as the ISO, the ITU, the IEEE, and the ETSI.

VCPS: Vehicular Cyber-physical Systems for Smart Road Services

Abstract: This paper proposes the design of Vehicular Cyber-Physical Systems (called VCPS) for smart road services in vehicular networks. Our VCPS realizes mobile cloud computing services where vehicles themselves or mobile devices (e.g., smartphones and tablets of drivers or passengers in vehicles) play a role of both cloud server and cloud client. First, this paper describes the architecture of vehicular networks for VCPS and the delay modeling for the interactive navigation and accident prediction, such as a mobile node's travel delay along its navigation path in vehicular networks. Second, the paper explains two VCPS applications as smart road services through the vehicular cloud, such as (i) interactive navigation service for the efficient driving and (ii) pedestrian protection service against road accidents.
