Decision Making Model

<p>Recent advancements in embedded sensing system, wireless communication technologies, big data, and artificial intelligence have fueled the development of Internet of Vehicles (IoV), where vehicles, road side unit (RSUs), and smart devices seamlessly interact with each other to enable the gathering and sharing of information on vehicles, roads, and their surrounds. As a fundamental component of IoV, vehicular networks (VANETs) are playing a critical role in processing, computing, and sharing travel-related information, which can help vehicles timely be aware of traffic situation and finally improve road safety and travel experience. However, due to the unique characteristics of vehicles, such as high mobility and sparse deployment making neighbor vehicles unacquainted and unknown to each other, VANETs are facing the challenge of evaluating the credibility of road safety messages. In this paper, we propose a blockchain-based trust management system using multi-criteria decision-making model, also referred to as Trust<sup>Block</sup><sub>MCDM</sub>, in VANETs. In the Trust<sup>Block</sup><sub>MCDM</sub>, each vehicle evaluates the credibility of received road safety message and generates the trust value of message originator. Due to the limited storage capacity, each vehicle periodically uploads the trust value to a nearby RSU. After receiving various trust values from vehicles, the RSU calculates the reputation value of message originator of road safety message using multi-criteria decision-making model, packs the reputation value into a block, and competes to add the block into blockchain. We evaluate the proposed Trust<sup>Block</sup><sub>MCDM</sub> approach through simulation experiments using OMNeT++ and compare its performance with prior blockchain-based decentralized trust management approach. The simulation results indicate that the proposed Trust<sup>Block</sup><sub>MCDM</sub> approach can not only improve fictitious message detection rate and malicious vehicle detection rate, but also can increase the number of dropped fictitious messages.<br></p>

Purpose This paper aims to examine how reckless driving scenes in action movies affect young male drivers’ perception of reckless drivers and proposes a targeted social marketing strategy to counteract this effect. Design/methodology/approach The hypotheses were tested through a 2 (reckless driving scenes vs control) × 2 (road safety advertising vs control) online experiment with 151 young male drivers. Findings Reckless driving scenes in action movies prime a positive image of reckless drivers which impacts young male drivers’ attitudes and reckless driving intention. However, a road safety message specifically addressing the positive image of reckless drivers efficiently counteracts this effect. Research limitations/implications A few studies have experimentally tested the impact of reckless driving promotion on young drivers’ attitudes and intention, but none have analysed this impact in terms of the development of a positive image of reckless drivers. In addition, this study emphasises that a targeted message based on social norms can cancel the effect of reckless driving promotion and have a beneficial impact on the most risk-prone drivers. Practical implications Social marketers working in the field of road safety can improve the efficacy of their social marketing programmes by taking into consideration the positive image of reckless drivers promoted by the media. Social implications Practitioners should develop interventions and targeted messages that help young drivers cultivate a less idealised and masculine social image of reckless drivers. Originality/value This paper enhances the awareness of the effect that the media’s positive depiction of reckless drivers can have on the youth and proposes a strategy to counteract this effect.

Message Broadcasting

Vehicular Ad Hoc Network (VANET) communication promises a vast array of applications ranging from road safety and driving comfort. Safety message broadcasting plays a significant role in highway safety in which the safety alert messages have to be delivered immediately to the vehicles located in the risk boundary area. Most of the current research attempt to select optimal relayer for safety message rebroadcasting. However, relayer selection models are not efficient, especially in a high-density VANET, as they cause a high delay in safety message delivery and lead to multiple accidents at the incident spot. To avert these issues, this work proposes a QoS Routing Protocol (QoRP) that aims to enhance the road safety in both sparse and dense VANETs.

Introduction: Road safety campaigns in Australia typically have simple, hit home messages with captions overlaid on photos. The Australian stop, revive, survive campaign is well-known, with accompanying photos displaying red fatigued eyes with the words; tired eyes, yawning, driver fatigue: wake up to the signs. Otherwise, the stop, revive, survive is shown with a windy road ahead viewed through a dashboard.Objectives: The aim of this project was to create a helmet safety message utilising a photograph along with several text words alongside.Methods: A photograph taken by Stephen Hilton of a motorcyclist with no helmet, holding one handlebar, was utilised with the words;‘Helmet, Handlebars, Headlights’ overlaid above along with arrows. This safety design was shown to forty persons, in order to obtain brief feedback and comments on whether this had the potential to convey the message about the need for a helmet in particular. The comments were gathered, collated and then common themes were identified.Results and Discussion: Five emerging themes were identified that included; The message is simple and straight to the point, cultural awareness is required, the need to enforce it as law, motor cycle riders think they are invincible and finally respondents were unsure whether it would work. A word cloud was created capturing and highlighting the main words stated in larger font, while words used infrequently were displayed in smaller font.Conclusion: More than half of the respondents questioned thought the idea was simple, straight to the point and hence should work.

VANET is branch of networking that is used for communication in intelligent transportation system. In this process of VANET various nodes are interconnected to each other and road side units. R2R, V2V and V2R communication has been done in VANET. Due to variouscommunications under VANET routing protocols have overhead for computation of shortest path and transmission of information with minimum delay. Delay in the network cause minimum safety. In this paper an approach has been proposed that can be used for transmission of safety message over the network with minimum delay. On the basis of proposed approach safety message can be transmitted in shortest interval of time so that safety can be achieved in the network.

Introduction. In the course of their professional activities, traffic police inspectors of State Road Safety Inspectorate (SRSI) are exposed to harmful working conditions. The aim of study is to provide scientific justification for the periods of service of inspectors that are important for the diagnosis of early signs of professionally caused diseases. Materials and methods. The study was carried out in a group of traffic police inspectors of the traffic police in accordance with the ethical standards set forth in the Declaration of Helsinki, 1975 (with additions, 1983), a positive conclusion of the ethical committee. The age of the traffic police officers was 24-50 years old, the experience was 1-19 years (average values 34±0.46 and 8.21±0.40 years). Results. In the course of the study, a class of working conditions was determined-3.4. low-level traffic police officers showed signs of disadaptation, a high risk of morbidity with temporary disability and professionally caused pathology of the cardiovascular, musculoskeletal, nervous, endocrine, and digestive systems. Conclusions. It is advisable to conduct an in-depth preventive medical examination of inspectors after 1-2 years of service. The first 4 years of service are important for preventive measures.
