“…However, the key challenge remains on how to ensure efficient data dissemination considering, the high mobility of nodes (moving vehicles), stringent delay requirements, and adequate trust management [39]. In this vein, Zhao et al [40] provide an Optimal Transmission Reliability Enhancement Mechanism (OTREM) designed to improve the quality of Emergency Warning Messages (EWM) propagation in vehicular cooperative driving systems. The main idea of OTREM is to use an improved finite automata to minimize transmission delays, error rate, and redundancy.…”

With the proliferation of embedded technologies and wireless capabilities, today's vehicles are no longer isolated mechanical machines. They become part of a hyper-connected system-Intelligent Transportation Systems (ITS)-that has the potential to support multiple levels of autonomy and intelligence improving considerably the safety, efficiency, and sustainability of transportation networks. However, this raises new security issues that make the whole system prone to cybersecurity attacks that threaten both the safety and privacy of all road-users. This paper gives a short background tutorial on the main security issues and the different attacks that hinder Intelligent Transport Systems. To enable secure and safe ITS applications, this paper provides a comprehensive analysis of existing solutions and highlights their strengths and limitations. Finally, this survey presents key challenges in the field, and discusses recent trends that must be factored in by researchers, implementers, and car manufactures to improve the security of ITS.

“…Based on such method, the underlying relationship between traffic flow and crash may be better explored. us, active regional traffic control and management strategies [11][12][13][14][15] could be expected to improve macroscopic safety, by managing traffic flow in some certain state with lower crash risk.…”

Macrolevel crash modeling has been extensively applied to investigate the safety effects of demographic, socioeconomic, and land use factors, in order to add safety knowledge into traffic planning and policy-making. In recent years, with the increasing attention to regional traffic management and control, the safety effects of macrolevel traffic flow parameters may also be of interest, in order to provide useful safety knowledge for regional traffic operation. In this paper, a new spatial unit was developed using a recursive half-cut partitioning procedure based on a normalized cut (NC) minimization method and traffic density homogeneity. Two Bayesian lognormal models with different conditional autoregressive (CAR) priors were applied to examine the safety effects of traffic flow characteristics at the NC level. It was found that safety effects of traffic flow exist at such macrolevel, indicating the necessity of considering safety for regional traffic control and management. Furthermore, traffic flow effects were also examined for another two spatial units: Traffic Analysis Zone (TAZ) and Census Tract (CT). It was found that ecological fallacy and atomic fallacy could exist without considering traffic flow parameters at those planning-based levels. In general, safety needs to be considered for regional traffic operation and the effects of traffic flow need to be considered for spatial crash modeling at various spatial levels.

“…A system with a tight coupling of cyber and physical objects is called cyber‐physical system (CPS), and based on reference, a CPS consists of (1) physical, biological, or engineered systems that are usually large‐scale and complex and (2) a cyber core, comprised of communication networks and computational availability that monitors, coordinates, and controls the physical part. Such systems interact intensively between physical entities and cyber infrastructure and commonly exist in the industrial processes and our daily lives . CPSs are hot topics recently and literature for investigation on CPSs is available .…”

Summary This article investigates the sensor attack detection and isolation problems for cyber‐physical systems under attacked situation. To begin with, an overall system is constructed for the network of dynamic system and all the issues are dealt with for the overall system instead of every subsystem. Then, we prove that the preconditions which are made on the original subsystem can be transferred on to the overall system. After this, for the overall system, a sliding mode observer that is robust to the disturbance but sensitive to the sensor attack is designed as sensor attack detector to issue an alarm when at least one subsystem is attacked. In addition, we cope with the sensor fault isolation problem by building an augmented descriptor system for the overall system and we further prove that the precondition can be kept for the augmented descriptor system. Then, another robust sliding mode observer is designed to reach the goal of attack isolation. Finally, a simulation example is given to verify the effectiveness of the proposed methods.
