Driving Task

While car drivers consist the vast majority of road users, motorcycle drivers are considered among the most vulnerable ones with significant participation in accidents. The present study investigates the role of elements that permanently exist in the road environment and affect motorcyclist’s behavior since their usefulness requires visual contact between them and the rider during a certain period of time. Therefore, on such an occasion the riders do not monitor the road ahead which is considered as a fundamental driving task and hence the visual search and scan is not directed to the frontal view. The main objective of this paper is to identify and evaluate certain aspects of motorcyclists’ behavior influenced by exterior factors, such as observation of vertical signage or advertisement signs, by using naturalistic data. Motorcyclist’s visual behavior is evaluated via a continuous recording of his gaze, which acts as the main indicator regarding the rider’s performance, with the use of special equipment under naturalistic riding conditions. The selection of a naturalistic method permits continuous data recording, producing real-time data. Thus, the results are reliable and valid to the maximum possible extent. This research is based on a medium-scale experimental procedure that took place in three different road sections in Western Greece. A number of 11 motorcyclists participated in the study. The present research may be used as a tool to improve road infrastructure and to identify attitudes that pose a risk to rider’s safety aiming to the creation of a safer road environment, which will lead to less fatal and serious accidents.

Group Characteristics

So far, research on pedestrians’ gaze behavior while crossing roads has mainly focused on individual pedestrians rather than groups. However, pedestrians often travel in groups especially in downtown areas. This observational study investigated how group characteristics (group size and movement of the group), situational factors (presence of traffic), and demographic variables (age and gender) influence pedestrians’ gaze behavior towards traffic during road crossing. A total of N = 197 pedestrians were observed of whom n = 24 traveled alone, n = 128 traveled in groups of two or three, and n = 45 traveled in groups of four or more. Results indicated that with increasing group size, the odds to observe traffic decreased. Diffusion of responsibility among group members might explain this effect. Finally, pedestrians’ group characteristics should be considered when developing automated vehicles that interact with vulnerable road users.

This paper presents research results focused on pedestrians’ crossing behaviour, the role of habit and routine route choice, pedestrians’ perceived safety and comfort, preferences, and waiting times. Data was collected and analysed using rapid on-site interviews with pedestrians, on-site observations and video recordings. The results indicate that vulnerable pedestrians choose different crossing strategies: waiting for a driver to give way to them rather than waiting for a safe gap to pass, and require a much more cooperative approach from drivers than other pedestrians. The results of the study lead to the conclusion that the removal of the crossings reduced pedestrians’ perceived safety and comfort, on the other hand, their awareness has been raised. While adult pedestrians can cope with the new situation relatively well and cross the road without major difficulties, the same does not apply to vulnerable road users.

Objective A driving simulator study explored how drivers behaved depending on their initial role during transitions between highly automated driving (HAD) and longitudinally assisted driving (via adaptive cruise control). Background During HAD, drivers might issue a take-over request (TOR), initiating a transition of control that was not planned. Understanding how drivers behave in this situation and, ultimately, the implications on road safety is of paramount importance. Method Sixteen participants were recruited for this study and performed transitions of control between HAD and longitudinally assisted driving in a driving simulator. While comparing how drivers behaved depending on whether or not they were the initiators, different handover strategies were presented to analyze how drivers adapted to variations in the authority level they were granted at various stages of the transitions. Results Whenever they initiated the transition, drivers were more engaged with the driving task and less prone to follow the guidance of the proposed strategies. Moreover, initiating a transition and having the highest authority share during the handover made the drivers more engaged with the driving task and attentive toward the road. Conclusion Handover strategies that retained a larger authority share were more effective whenever the automation initiated the transition. Under driver-initiated transitions, reducing drivers’ authority was detrimental for both performance and comfort. Application As the operational design domain of automated vehicles (Society of Automotive Engineers [SAE] Level 3/4) expands, the drivers might very well fight boredom by taking over spontaneously, introducing safety issues so far not considered but nevertheless very important.

This study aims to determine the role of traffic police know the increase in traffic discipline and to know the police efforts to improve traffic discipline. The writing is done using the method of juridical sociological approach, the court concluded that the data obtained from an answer. This type of research used in the study of law is that legal research is descriptive. The results obtained that the role of the police carrying out of order and law enforcement in the field of traffic is by doing the demolition of highway users. The role of traffic police in improving the discipline and enforcement of traffic laws in Police Jurisdiction Police Bogor by the dissemination of traffic rules. The area is usually only seen one or two officers, more visible police officers assisted school children (MCC), Police Friends of Children (PSA), Satpol PP, Transportation Agency, the military and others. As a result the location of the normally chaotic start neat. Public transportation that generally take the path carelessly began to follow the sign that rules have been determined, including stops behind the road markings. Socialization is aimed at people. With the hope of growing awareness of the importance of order and lintas.Tak than mere appeals, undisciplined road users will be immediately ticketed. Range of efforts made to suppress the Bogor Police traffic policeman level of traffic violations is put tape shock, making the road median, make a zebra crossing, putting personnel at vulnerable places, and patrolling the road. When road users do not comply with rules set then the action will be penalized with a verbal reprimand and prosecution by giving a speeding ticket. Bogor Police traffic policeman in reducing offenses involving police discipline is the Friends of Children (PSA) for kindergarten children, coaching on a motorcycle taxi driver, extension to the applicant's driver's license, do some police operations.

This article discusses the augmenting influence of Artesunate (ART) in combination with β-lactams (amoxicillin/clavulanic acid) antibiotic in sepsis mice models infected by a lethal challenge dose of live coagulase positive enterotoxigenic (Sec) MRSA that was isolated from a case of chronic bovine mastitis. The main goal is to find an appropriate treatment to overcome resistance mechanism of MRSA towards β-lactams antibiotic. Fifty healthy adult Swiss mice divided into 5 equal groups were used in the experimental procedure. The infected group that treated with both ART and β-lactams (amoxicillin/clavulanic acid) antibiotic revealed complete inhibition of MRSA count with complete normal macroscopic and histopathological features. We suggest that ART can potentiate the antibacterial action of β-lactams (amoxicillin/Clavulanic) acid against MRSA infection. The combination of ART and antibiotic can overcome MRSA resistance mechanism and so could be considered a novel candidate to overcome mastitis and/or sepsis caused by MRSA.

Dramatic advances in therapy for pulmonary arterial hypertension (PAH) in the last 20 years have improved survival from a median of 2.5 years in the pretreatment era to 7.5 years currently. However, impressive as that may seem, it is important to note that a median survival of 7.5 years is equivalent to that of surgically resected non-small cell lung cancer, thus underscoring the importance of lung transplantation as a treatment option in patients with PAH. In this edition of Advances, Edelman has reviewed the pathway to transplantation for patients with PAH, detailing the recommendations for timing of referral, listing for lung transplantation, the role of the lung allocation score in allocating a donor organ, and the outcome of lung transplantation.

This chapter explores the role geo-location technologies may play on the road towards achieving jurisdictional interoperability. The relevant technologies involved are introduced briefly, their accuracy examined, and an overview is provided of their use, including the increasingly common use of so-called geo-blocking. Attention is then given to perceived and real concerns stemming from the use of geo-location technologies and how these technologies impact international law, territoriality, and sovereignty, as well as to the role these technologies may play in law reform. The point is made that the current ‘effect-focused’ rules in both private international law and public international law (as those disciplines are traditionally defined), are likely to continue to work as an incentive for the use of geo-location technologies.
