The use of mobile phones while driving has been a hot topic in the field of driving safety for decades. Although there are few studies on the influence of gesture control on in-vehicle secondary tasks, this study aims to investigate the impact of gesture-based mobile phone use without touching while driving from the perspective of multiple-resource workload owing to visual, auditory, cognitive, and psychomotor resource occupation. A novel gesture control technique was adopted for secondary task interactions, to recognize the gestures of drivers. An experiment was conducted to study the influences of two interaction modes, traditional touch-based mobile phone interaction and gesture-based mobile phone interaction, on driving behavior in three different cognitive level task groups. The results indicate that gesture-based mobile phone interaction can improve driving performance with regard to lateral position-keeping ability and steering wheel control; nevertheless, it has no significant impact on longitudinal metrics such as driving speed, driving speed variation, and throttle control variation. Gesture-based mobile phone interactions have a larger effect on secondary tasks with medium cognitive load but not on actual operation tasks. It was also verified that the performance of gesture-based mobile phone interaction was better in secondary mobile phone tasks such as switching (e.g., switching songs) and adjusting (e.g., adjusting volume) than the traditional interaction mode. This study provides the theoretical and experimental support for human–computer interaction using gesture-based mobile phone interactive control in future automobiles.

Mobile phone use while driving is a major cause of driver distraction, affecting driving performance and increasing accident risk. Governments have responded to this with the implementation of legislation prohibiting the use of mobile phones, under specific conditions, mainly adopting the hands-free use. Still, mobile phone is a cause of several types of distraction rather than just manual. This study explores the effect of mobile phone use while driving via a simulator experiment. Participants drive under various types of mobile phone use mode- namely, handheld, hands-free (wired earphone), and speaker to capture this effect. Results highlight the effect of mobile phone use, regardless of the use mode, on driving behaviour through specific indicators: maximum driving speed, reaction time, and lateral position. In particular, considering the aforementioned parameters the handheld mode demonstrates safer driving behaviour compared to the speaker mode. The results of this study stress the need for a reconsideration of the present legislation.

Handling instability is a serious threat to driving safety. In order to analyze the handling stability of a tractor semitrailer, a handling diagram can be used. In our research, considering the impact of multiple nonsteering rear axles and nonlinear characteristics of tires on vehicle handling stability, the handling equations are developed for description of stability of tractor semi-trailer. Then we obtain handling diagrams so as to study the influence of driving speed, loaded mass, and fifth wheel lead on vehicle handling stability. The analysis results show that the handling stability of a tractor semi-trailer when the tractor has two nonsteering rear axles is better than that when the tractor has only one nonsteering rear axle. While the stability in the former case is slightly influenced by driving speed and loaded mass, the latter is strongly influenced by both. The fifth wheel lead is found to only slightly influence handling stability for both tractor semi-trailers. Therefore, to ensure the driving safety of tractor semi-trailers when the tractor has only one nonsteering rear axle, much stricter restraints should be imposed on driving speed, and the loaded mass must not exceed the rated load of the trailer.

Background: The main purpose of study was to assess the impact of using mobile phones among young Ukrainians (age 17-25) on auditory system. We conducted a study using anonymous questionnaires and with using a method of objective audiometry (otoacoustic emission). Finally, we compared our results with results of studies which were conducted in Sweden and Finland. Those studies were first among all the others with assessment of association between amount of mobile phone use and frequency of headache, tinnitus or hearing loss at 4-year follow-up. Methods: The participants were chosen among volunteers (n=251). All of them received anonymous questionnaires. We made stratified sample by age, sex, type of phone used, duration of phone calls, using of headphones during calls, symptoms appearing after using cell phone (headache, tinnitus, hearing loss). Results: The age of respondents was 17-25 years (32,3% - 22 years, 13,1% - 19 years, 12,4% - 20 years, 10,8% - 23 years., 8,4% - 21 years., 8% - 18 years, 7,6% - 17 years, 2,8% - 24р., 2,8% - 25 years). Due to this data the median age of participants was 22 years. Sex: female – 74.3%, male – 25.7%. Most of participants were using mobile phones (99.2%). 51.8% of respondents were always using headphones during phone calls, 8.8% - never used headphones during phone calls, 39,4% - were rarely using headphones during phone calls.  We assess the association between mobile phone use and appearing symptoms after phone calls. 3.6% of respondents reported a headache after phone calls, 96.4% were free of this symptom after phone calls. 58.2% reported headache at least once a week, 41.8% - were free of this symptom. 42.2% of respondents reported tinnitus: 1.6% reported tinnitus every day, 4.8% once in 2-3 days, 35.9% reported this symptom rarely (less than once a week). 57.8% of respondents were free of tinnitus. 21.5% of respondents reported hearing loss, 78.5% were free of hearing loss. Most of respondents associate headache with fatigue, sleep deprivation, stress, weather change, sleep disorders, arterial hypertension, hunger, frequent phone calls. Respondents who complained of hearing loss were offered to pass objective audiometry (optoacoustic emission).6 respondents took part in this examination. In 85 ears of respondents (71%) who complained of hearing loss it occurs on 8000 Hz. In 95 ears of respondents (79%) who complained of hearing loss it occurs on 5714 Hz. Pearson correlation coefficient between our results and results of Northern Europe studies was 0.935, suggesting a strong linear association.

Mobile phone use at pedestrian crossings has been recognized as a growing problem in the field of traffic safety. The objective of the paper is to analyze the impact of mobile phone use at pedestrian crossings considering specific territory. Signalized and unsignalized intersections are observed in the study. Several factors having the impact on unsafe pedestrian crossing behaviour are identified such as: age, location and the type of mobile phone using. The model of unsafe pedestrian behaviour based on displayed mobile phone use while crossing the intersection is constructed. It has been shown in this research that talking and texting on mobile phone distract pedestrians. Listening to music does not affect pedestrians to behave unsafely because it requires less cognitive activity than talking or texting. Also, location affects the pedestrian crossing behavior. The results of this research can serve the purpose of preventing the mobile phones use and reduce the negative impact on pedestrian crossing behavior.

BACKGROUND: The fetal heart rate (FHR) is a good marker of fetal well-being during labour. Cardiotocography is used to record the FHR and uterine contractions and can detect possible fetal hypoxia. Mobile phones use, and obesity is suggested to influence the FHR and cardiovascular development. AIM: The present study aimed to study the differences in FHR pattern between fetuses of obese vs non-obese groups when using a mobile phone. METHODS: We conducted a clinical trial to test the impact of mobile phone use on FHR using a single mobile phone with Specific Absorption Rate rating of 0.99 W/kg for 10 minutes. Data from this clinical trial were analysed to compare the FHR pattern between fetuses of obese women (exposed group) vs those of non-obese women (control group). The two study groups (obese vs non-obese) were compared regarding four FHR patterns: baseline FHR, variability, acceleration and deceleration scores. Data were analysed by SPSS software version 23.0 using the independent-samples t-tests. RESULTS: Sixty-nine women were included in the final analysis (obese group: n = 22 and non-obese group: n = 47). Fetuses of the obese women had significantly higher baseline FHR and less FHR variability scores when compared with fetuses of the non-obese women (mean difference 2.9 and 3.18, respectively). CONCLUSION: Fetuses of obese women had abnormal FHR pattern compared with fetuses of non-obese women. The use of mobile phone slightly influenced the FHR variability score. These results highlight the importance of proper management of obesity in women within the childbearing period.

Several actions and/or operations might interfere with those required during car-driving and thus elicit dual task conditions. Those related to driving itself involve manipulating commands or instruments and should be automated during the learning to drive period to ensure safety. Others, independent of driving may be delayed (eating, smoking a cigarette). Finally, others like manipulating a navigation system or holding a cellphone have potential interference more or less related to driving. The authors now step back about 25 years to analyze the interference between driving and phoning and assess the risk associated with it. Epidemiology provides an overview of mobile phone use and hypotheses about accident causes. If hand-held phones obviously interfere with driving actions, the authors should explain why hands-free kits do not solve all safety concerns. Then, analyzing the operations affected by phoning and describing the objective measures revealing impaired driving performance will address this issue. The authors finally highlight the conditions for relatively safe phone use as well as those that should be banned. Deciding to phone or not will thus depend on driving safety education, during which skills of caution should have been learned.

Mobile phone use while driving is one of the major road safety risks. In surveys from different settings, the rate of mobile phone use while driving ranged from 1 to 11%. Literature from observational and experimental studies show that driving capacities such as reacting to traffic hazards, maintaining a central lane position, maintaining a safe distance and speed are negatively affected when using a mobile phone while driving. Several epidemiological studies suggest that motor vehicle collision risks increase by two to nine times when using a mobile phone (handheld or hands-free) compared to not using the phone while driving. Considering these findings, almost three-quarters of the countries have adopted legislation banning the use of handheld mobile phone devices while driving. These interventions, however, are insufficient to deal with the use of hands-free mobile phones while driving and texting which are challenging to ascertain and prevent. Currently, “in-vehicle” and collision avoidance technologies are being evaluated to further reduce the impact of these road menaces in our society.

Mind wandering is a poorly understood phenomenon that can undermine driving safety. Driving performance measures have been found to be associated with mind wandering (e.g., steering wheel movements, standard deviation of lateral position, and speed variation). However, no one measure can fully describe the driver behavior associated with mind wandering. Therefore, in this paper we explore the effect of mind wandering on nine steering measures with data collected from a study that included nine drivers over two sessions of driving over five days. Participants were periodically probed to report their attentional state–whether they were mind wandering or focusing on the task. We used two dimensionality-reduction techniques—Principal component analysis (PCA) and t-distributed stochastic neighbor embedding (t-SNE)—to visualize the dimensions underlying the nine measures. Comparing PCA to t-SNE highlights the benefits of t-SNE in revealing the fine structure that differentiates driving behavior. These visualizations show that a) driver engagement increased during roadway curve segments, and b) mind wandering manifests itself through several types of steering behavior.
