    This paper details the development of, and perceived role and effectiveness of an innovative intervention designed to ultimately improve the safety of a group of community care (CC) nurses while driving. Recruiting participants from an Australian CC nursing car fleet, qualitative responses from a series of open-ended questions were obtained from drivers (n = 36), supervisors (n = 22), and managers (n = 6). The findings supported the effectiveness of the intervention in reducing self-reported speeding and promoting greater insight into oneā€™s behaviour on the road. This research has important practical implications in that it highlights the value of developing an intervention based on a sound theoretical framework and which is aligned with the needs and beliefs of personnel within a particular organisation

    Vehicular Ad Hoc Networks (VANET) has mostly gained the attention of today's research efforts, while current solutions to achieve secure VANET, to protect the network from adversary and attacks still not enough, trying to reach a satisfactory level, for the driver and manufacturer to achieve safety of life and infotainment. The need for a robust VANET networks is strongly dependent on their security and privacy features, which will be discussed in this paper. In this paper a various types of security problems and challenges of VANET been analyzed and discussed; we also discuss a set of solutions presented to solve these challenges and problems.Comment: 6 pages; 2010 Second International Conference on Network Applications, Protocols and Service

    Speed limit enforcement as perceived by offenders: Implications for roads policing

    Copyright@ 2010 The Authors. This is the post-print version of the article. The final published version may be accessed at the link below.Getting caught for speeding is an emotive issue. This paper analyzes an unexpected source of data captured by unprompted comments left at the end of a questionnaire by a sample of British drivers who all had penalty points on their licences, many for speeding.The paperā€™s relevance to roads policing is that perceived fairness of police procedures is crucial in shaping public support, and comments made by this sample of offending drivers indicated that speed limit enforcement through the operation of the speed camera system was often seen as unfair. Since roads policing is closely linked with this and with many drivers having penalty points on their licences, the views of such drivers could be instructive, given the continuing reliance on camera technology and the need for police to offer public reassurance. Finally, the implications for roads policing are considered.The data used in this paper are derived from a study funded by the Department for Transport (DfT)

    Childā€“parent interaction in relation to road safety education : Part 2 ā€“ main report

    ā€¢ Children and young people are particularly vulnerable road users. ā€¢ Child pedestrian injury rates are poor compared with the rest of Europe. ā€¢ The factors that impact on childrenā€™s road safety and their capability in traffic are numerous, multi-faceted and complex. ā€¢ ā€¢ The systematic review conducted by Cattan et al. (2008) as the initial phase of this study shows that: ā€¢ parents see themselves as being responsible for developing their childrenā€™s road safety awareness and skills; ā€¢ holding hands is the most common road-crossing interaction between parents and children; ā€¢ adults rarely make use of road-crossing events to give oral instructions; ā€¢ few parents and children are consistent in their road-crossing behaviour; ā€¢ roadside training by volunteer parents for groups of children can lead to significant improvements in childrenā€™s road safety behaviour; ā€¢ belief in fate seems to influence the likelihood of parents using restraints, such as seat belts or car seats, with their children; and ā€¢ parentsā€™ understanding of the childā€™s perspective in carrying out road safety tasks and their motivation to actively involve their child in making decisions at the roadside can be improved through training. ā€¢ Social Cognitive Theory (Bandura, 1986) suggests that the modelling role of parents can make a significant contribution to childrenā€™s learning about road use and their development of traffic competence whether or not parents are aware of this. ā€¢ The main aim of this study was to explore the way parents influence children and young people aged 0ā€“16 years to be safer road users. ā€¢ This study included children and young people aged 5ā€“16 and parents of children aged 0ā€“16 years old

    Data-centric Misbehavior Detection in VANETs

    Detecting misbehavior (such as transmissions of false information) in vehicular ad hoc networks (VANETs) is very important problem with wide range of implications including safety related and congestion avoidance applications. We discuss several limitations of existing misbehavior detection schemes (MDS) designed for VANETs. Most MDS are concerned with detection of malicious nodes. In most situations, vehicles would send wrong information because of selfish reasons of their owners, e.g. for gaining access to a particular lane. Because of this (\emph{rational behavior}), it is more important to detect false information than to identify misbehaving nodes. We introduce the concept of data-centric misbehavior detection and propose algorithms which detect false alert messages and misbehaving nodes by observing their actions after sending out the alert messages. With the data-centric MDS, each node can independently decide whether an information received is correct or false. The decision is based on the consistency of recent messages and new alert with reported and estimated vehicle positions. No voting or majority decisions is needed, making our MDS resilient to Sybil attacks. Instead of revoking all the secret credentials of misbehaving nodes, as done in most schemes, we impose fines on misbehaving nodes (administered by the certification authority), discouraging them to act selfishly. This reduces the computation and communication costs involved in revoking all the secret credentials of misbehaving nodes.Comment: 12 page
