The association between road traffic accidents and visual functions: A systematic review and meta-analysis.

Poor visual functions have been reported to be related to the occurrence of road traffic accidents. To review the association between visual function and road traffic accidents (RTAs) from published relevant empirical studies. Worldwide. A random effects (RE) model meta-analysis was conducted using STATA 18. Statistical tests conducted include meta-summary statistics, RE meta-analysis (forest plot), meta-regression (relationship between mean age and effect sizes), funnel plots, Egger's and Begg's tests for publication bias and small study effects. A total of 17 relevant studies, which were either cross-sectional or observational by design, were included in the meta-analysis. Reported effect sizes were within computed confidence intervals (CI) at 95%. The computedQtest of homogeneity was 61.94. The overall mean effect size of 1.43 (95% CI of 0.985-1.883) was statistically significant at a 5% level (Z= 6.26;p 0.001). TheI-squared = 62.17% (p= 0.00) confirmed moderate heterogeneity and theQ-value of 61.94 (p= 0.00) rejected the null hypothesis that the effect size was the same in all the studies. The funnel plot showed that the remaining majority of 13 studies were within the funnel plot on the right-hand side of the line of no effect. These results provide evidence of associations between visual functions and RTAs, and highlight the need for targeted interventions and further research to address the challenges associated with impaired visual functions and road safety.Contributions:The study contributes to the understanding of the implications of visual functions for road safety.

The calls to 112 command and control center and evaluation of use of the Emergency Ambulance Service in Denizli

Objective: In this study we studied the calls to 112 command and control center in 2012-2013 years in our province and we aimed the evaluation of use of the emergency ambulance service in our province. Methods: By evaluating emergency call forms that is taken 112 command and control center head physician’s office, a descriptive study was done retrospectively. SPSS 17 program is used for the statistical analysis in this study. Results: It is identified that 51.8% of 1176126 emergency service applicants was male in 2012, 52.3% of 1185019 emergency service applicants was female in 2013. Ambulance service utilization was highest in summer (27%) and the peak value was in august. It is detected that 94% of the calls was unnecessary. The ambulance service utilization by the patients age 65 and over was 30% in 2012 and 2013. It is also identified that the mean ambulance arrival time to the patients was 8.6 min. in 2012 and 9.1 min. in 2013. As we determined, most of the reasons of emergency calls were medical diseases (72%) and traffic accidents (12%). In the patient’s classification according to their pre-diagnosis, the biggest patient group was trauma cases. In 2012 the trauma cases have had 23,3% rate among the pre-diagnosis reasons and in 2013 the value was 22,2%. In our study, the highest rate of ambulance exists is hospital transfer (64.2% in 2012, 63.1% in 2013). Most of the cases which are transported with ambulance have been gone to Denizli State Hospital (32.4%). Conclusion: The high rate of unnecessary calls to command and control center (95,5%) is a serious problem for the quality of service. Because of the fact that these kind of calls make 112 KKM busy unnecessarily; patients, which must have a priority to access to emergency services because of their severe illnesses, don’t arrive on time. So education programs or public spotlights should be performed to improve the public’s knowledge.

Efficacy and safety of insomnia treatment with lemborexant in older adults: analyses from three clinical trials.

Insomnia is more common as people age. Several common hypnotics used to treat insomnia often do not adequately alleviate sleep issues in older adults and may be associated with negative residual effects such as an increased risk of falls, cognitive impairment, automobile accidents, and lack of response to auditory stimuli. The objective of these analyses of three clinical studies was to investigate the efficacy and safety of the dual orexin-receptor antagonist lemborexant (LEM) in older adults. Study E2006-G000-304 (Study 304; NCT02783729) was a randomized, double-blind, placebo (PBO)-controlled, active-comparator trial where subjects with insomnia disorder received LEM 5 mg (LEM5), LEM 10 mg (LEM10), zolpidem tartrate extended-release 6.25 mg (ZOL), or PBO for 30 days. In crossover Study E2006-E044-106 (Study 106; NCT02583451), healthy subjects (good sleepers) received LEM 2.5 mg, LEM5, LEM10, or PBO for eight nights or zopiclone on days 1 and 8 (and PBO on days 2-7). In crossover Study E2006-A001-108 (Study 108; NCT03008447), healthy subjects received a single dose of LEM5, LEM10, PBO, or ZOL. Sleep assessments included polysomnography-based latency to persistent sleep (LPS), wake after sleep onset (WASO), WASO in the second half of the night (WASO2H), sleep efficiency, postural stability, middle-of-the-night and next-day cognitive performance, middle-of-the-night auditory awakening threshold and return-to-sleep latency, and driving performance. Overall, 453 of 1006 (45%; Study 304), 24 of 48 (50%; Study 106), and 28 of 56 (50%; Study 108) subjects were aged ≥ 65years. In Study 304, LEM decreased (improved) LPS, WASO, and WASO2H from baseline more than ZOL and PBO; subjects treated with LEM had greater increases in sleep efficiency (improved) than with ZOL or PBO. In both Studies 304 and 108, postural stability was not impaired at waketime in subjects who received LEM compared with PBO. At waketime, LEM did not impair memory compared with PBO. In Study 108, following middle-of-the-night awakening, LEM and ZOL did not affect subjects' ability to awaken to auditory stimuli; LEM did not affect tests of memory and attention. In Study 106, LEM did not impair next-day driving performance in healthy elderly compared with PBO. LEM was well tolerated in subjects aged ≥ 65years. LEM provided benefits on sleep variables without next-morning residual effects in subjects aged ≥ 65years, supporting LEM as a treatment option for older adults with insomnia. Study 304: ClinicalTrials.gov identifier, NCT02783729, date of registration, 26 May 2016. Study 106: ClinicalTrials.gov identifier, NCT02583451, date of registration, 22 October 2015. Study 108: ClinicalTrials.gov identifier, NCT03008447, date of registration, 2 January 2017.

Shear Thickening, Star-Shaped Polymer Electrolytes for Lithium-Ion Batteries.

The safety concerns associated with current lithium-ion batteries are a significant drawback. A short-circuit within the battery's internal components, such as those caused by a car accident, can lead to ignition or even explosion. To address this issue, a polymer shear thickening electrolyte, free from flammable solvents, has been developed. It comprises a star-shaped oligomer derived from a trimethylolpropane (TMP) core and polyether chains, along with the inclusion of 20 wt.% nanosilica. Notably, the star-shaped oligomer serves a dual function as both the solvent for the lithium salt and the continuous phase of the shear thickening fluid. The obtained electrolytes exhibit an ionic conductivity of the order of 10-6 S cm-1 at 20 °C and 10-4 S cm-1 at 80 °C, with a high Li+ transference number (t+ = 0.79). A nearly thirtyfold increase in viscosity to a value of 1187 Pa s at 25 °C and a critical shear rate of 2 s-1 were achieved. During impact, this electrolyte could enhance cell safety by preventing electrode short-circuiting.

Systematic quantitative evaluation of gene polymorphism and therapeutic effect of xingnaojing injection in patients with brain injury.

The incidence of brain injury is increasing year by year, and it has become one of the major diseases threatening human life in today's society. From the perspective of the causes of brain injury, it is mainly due to falls from high places, traffic accidents, etc. Severe brain injury patients often lose consciousness. In recent years, the emergence of integrated traditional Chinese and Western medicine has provided a new approach and new ideas for the treatment of craniocerebral trauma. The article systematically and scientifically expounded the role of Xingnaojing injection in the treatment of brain injury by comparing the GCS (Glasgow Coma Scale) score, changes in intracranial pressure, the incidence of complications after brain injury, the transformation from moderate brain injury to severe brain injury, and recovery of consciousness. For the problem of gene polymorphism in patients with brain injury, this article discussed the role of APOE2 (Apolipoprotein E2), ε3, ε4 in brain injury. All patients had a clear history of trauma and received strict nervous system examination and CT scanning when they were admitted to the hospital. After craniocerebral trauma surgery or conservative therapy, patients should take a Xingnaojing injection of 30 ml and a 0.9% sodium chloride injection of 250 ml after admission. After the operation, respiratory tract nursing should be strengthened, and patients who cannot eat should be given nasal feeding, acupuncture, and physiotherapy to prevent bedridden complications. The probability of epilepsy after brain injury was 27%. The article would help to evaluate the degree of brain damage and prognosis of patients.

Morphometrical and molecular identification of Echinococcus granulosus genotypes in wild canids in north of Iran.

The cestode Echinococcus granulosus causes cystic echinococcosis, a zoonotic parasitic infection that constitutes a significant public health risk. This parasite has been documented to have potential reservoirs and carriers among wild canids, namely wolves, foxes and jackals. This study aimed to determine the prevalence and molecular characteristics of E. granulosus sensu lato species/genotypes among wild canids in three northern, northeastern and north-western Iran regions. From 2019 to 2022, 93 wild canid carcasses (69 jackals), (22 foxes) and (2 wolves) were collected that were killed in car accidents or illnesses. Analyses of morphology and morphometry were performed to verify the presence of E. granulosus. To determine E. granulosus s.l. species/genotypes, polymerase chain reaction (PCR)-RFLP (ITS1) was performed utilizing the Bsh1236I (BstUI) restriction enzyme. COX1, NADH1 and ITS1 gene sequencing were also performed to confirm the PCR-RFLP results. During this study, 93 wild canids were examined, and 3.2% (95% CI: 0%-7%) of the 93 were infected with Echinococcus. The north-western region of Iran showed two out of 30 jackals (6.6%) infected with adult Echinococcus compared to one out of 35 jackals (2.8%) in the northern region. DNA from Echinococcus was detected in these individuals by PCR. Based on PCR-RFLP analysis of the ITS1 gene and sequencing of COX1, NADH1 and ITS1 gene, E. granulosus sensu stricto genotype was confirmed in the jackals that had been infected. Evidence shows that E. granulosus occurs in jackals in Iran, with the E. granulosus s.s. genotype being the most common. This parasite has been identified as a zoonotic parasite with a genotype that can be transmitted to livestock and humans. Establishing effective control measures to prevent the spread of echinococcosis and ensure public health is crucial.

Radiographic and Functional Outcome of Depressed Tibial Plateau Fractures Treated with Raft Plate with Bone Graft – A Prospective Study

Tibial plateau fractures are the fractures that involve the articular surface of the tibial condyles. The Schatzker and OA classifications are the most commonly used to classify these fractures. The Schatzker classification system is a widely recognized method used by orthopedic surgeons to categorize tibial plateau fractures into six distinct types. This classification helps in assessing the initial injury, planning the appropriate management strategy, and predicting the prognosis. Each type represents a different pattern of fracture, which can guide treatment decisions and expectations for recovery. These fractures typically result from the external(valgus) or internal(varus) forces on the knee with axial loading. In younger individuals, tibial plateau fractures are most commonly caused by road traffic accidents due to the high-energy impact. However, in elderly patients with osteopenic bone, even a simple fall can lead to these fractures because their bones are more fragile and susceptible to injury. The tibial plateau fractures are intra-articular fractures of the knee joint and are often difficult to treat and have a high complication rate, including early-onset osteoarthritis. Surgery is the preferred modality of treatment for these fractures, along with bone void fillers to address bone defects caused by the injury. At present, there is no consensus on the optimal method of fixation or the void filling to treat such fractures. Techniques of operative management of tibial plateau fractures have become more successful in achieving and maintaining reduction of the fracture. Still, avoiding malalignment of the limb has been shown to be at least as important as articular congruity to long-term joint viability.

Head-up Displays Improve Drivers’ Performance and Subjective Perceptions with the In-Vehicle Gesture Interaction System

In-vehicle infotainment systems can cause various distractions, increasing the risk of car accidents. To address this problem, mid-air gesture systems have been introduced. This study investigated the potential of a novel interface that integrates a Head-Up Display (HUD) with auditory displays (spearcons: compressed speech) in a gesture-based menu navigation system to minimize visual distraction and improve driving and secondary task performance. The experiment involved 24 participants who navigated through 12 menu items using mid-air gestures while driving on a simulated road under four conditions: HUD (with, without spearcons) and Head-Down Display (HDD) (with, without spearcons). Results showed that the HUD condition significantly outperformed the HDD condition in participants’ level 1 situation awareness, perceived workload, menu navigation performance, and system usability. However, there were trade-offs on visual fixation duration on the menu, and lane deviation. These findings will guide future research in developing safer and more effective HUD-supported in-vehicle gesture interaction systems.

Driving under the influence: An analysis of second-time offenders and intervention success, Turkey sample

Objectives Driving under the influence (DUI) of alcohol is a major public health issue that results in significant mortality, morbidity, and economic costs. Despite various penalties and interventions, DUI remains prevalent. This study examines the demographic characteristics, educational status, and involvement in motor vehicle accidents of second-time DUI offenders, aiming to identify factors influencing the success of educational interventions. Methods Between 2018 and 2023, 151 individuals whose driver’s licenses were suspended for a second DUI offense participated in this study. All participants applied to the Adıyaman Provincial Health Directorate, located in the southeast region of Turkey, to regain their licenses. Data were collected from application documents and digital records during and after the educational program, which included identity information, demographic characteristics, reasons for alcohol consumption, license duration, education level, educational success, frequency of alcohol use, and behavior under the influence. Penalties and traffic accidents in the last 5 years were also recorded. Results Participants with a high school education and above had a significantly higher success rate in the educational program (P = .03). Those without penalties (P = .001) and those not involved in traffic accidents (P = .006) also showed higher success rates. Conclusion Despite its limitations, this study shows that second-time DUI offenders who have previous traffic tickets or accidents are less likely to succeed in educational interventions. These findings suggest the need for tailored training programs, extended durations, and personalized evaluations to improve outcomes for these high-risk groups. Future research should explore prospective studies to confirm these results and guide intervention strategies.

An Influencing Factors Analysis of Road Traffic Accidents Based on the Analytic Hierarchy Process and the Minimum Discrimination Information Principle

Safe traffic is an important part of sustainable transportation. Road traffic accidents lead to a large number of casualties and property losses every year. Current research mainly studies some types of traffic accidents and ignores other types of traffic accidents; therefore, taking various types of road traffic accidents as a whole, an overall study of their influencing factors is urgently needed. To improve road traffic safety, taking various types of road traffic accidents as a whole, this paper analyzes the influencing factors and finds out the causative factors of road traffic accidents. A new index system of road traffic accident influencing factors is constructed based on the existing literature and real traffic data, and their subjective weights and objective weights are obtained by the analytic hierarchy process based on the subjective data and the normalization of the actual traffic data for Yizheng City, Yangzhou, China from January 2020 to December 2020, where the subjective weights are the main weights, and comprehensive weights are obtained by the minimum discrimination information principle correcting the subjective weights with the objective weights. Finally, the global weights, their ranks, and their weight differences are obtained. The main findings are as follows: (1) compared with the real traffic data, experts generally overestimate the impact of road factors on traffic accidents and underestimate the impact of human factors on traffic accidents; (2) in the first-level, human factors and road factors are the causative factors; (3) in the second-level, “motor vehicle drivers’ misconduct”, “road condition”, and “road section” are the causative factors; and (4) in the third-level, “slippery road”, “rain and snow weather”, “intersection”, and “untimely braking” are the causative factors. The research results can provide some scientific basis for improving road traffic safety.

Prevalence of Urogenital Injury following Road Accident: A Systematic Review.

Trauma complications have been one of the most serious public health concerns worldwide. In most reports, urogenital injuries (UGIs) are seen in approximately 10% of adult traumatic patients and less than 3% of children with multiple/severe trauma to the abdomen or pelvis. Traffic accidents are the most common cause of UGIs. The purpose of this study is to systematically determine the prevalence and types of UGIs after car accidents. The search strategy was aimed at finding relevant studies in October 2023. No restrictions on language or date were applied. The following criteria were considered eligibility criteria: reporting at least one epidemiological aspect of UGIs in people with road traffic injury (RTI) and a separate epidemiological analysis of RTIs in UGI (we also included those articles that pointed out all RTIs but separately mentioned UGIs). Two experts assessed the reporting quality of articles using standardized critical appraisal instruments from the Joanna Briggs Institute. Statistical analysis for this study was conducted using the CMA statistical software version 3.2.0. A total of 1,466,024 cases following RTIs through 107 studies were included in our review. Of these, 29 studies were related to children (20,036), and the others reported RTIs in adults (1,445,988). The total prevalence was 4.7%, and car accidents were responsible in 36 studies, followed by motorcycle accidents in 25, bicycles in 17 studies, and automobile-pedestrian collisions in 23 related studies. In subgroup analysis based on the damaged organ, the rate of bladder injury was 3.5%. This rate was 5.3% for kidneys. This systematic review and meta-analysis found that the prevalence of UGI following RTIs was 4.7%, with car accidents being the most common cause. UGIs were more prevalent in adults than in children, and bladder and kidney injuries were the most commonly reported types. The prevalence of UGI varied by country and study design.

Diaphyseal Tibia and Fibula Malunion Treated with Open Osteotomy and Internal Fixation: A Case Report

Diaphyseal fractures of the tibia and fibula often occur due to traffic accidents. Bone fractures can heal well with proper treatment. However, many cases that are neglected lead to complications such as malunion, particularly in developing countries. Malunion occurs when a fractured bone heals with the fragments in improper positions. Malunion in bone fractures can lead to complications such as decreased bone or limb function, deformities, pain, non-union, avascular necrosis, and limb shortening. This case study reports on a 29-year-old woman with malunion in the tibia and fibula due to a neglected bone fracture for eight months. Symptoms include pain, deformities, and limb shortening. The management involved open osteotomy and ORIF (open reduction with internal fixation), demonstrating that ORIF and osteotomy are successful surgical techniques for correcting malunion in this case. The goals of surgical treatment for malunion are to restore function, reduce discomfort, and correct visually apparent abnormalities.

Analysis of spine motion during prehospital extrication procedures in motorsport.

The appropriate extrication techniques for trauma patients after car accidents remain a topic of controversy. Various techniques for immobilizing the cervical spine during prehospital extrication have been investigated. This explorative study compared the amount of spinal motion during five different extrication procedures from a racecar and a rallycar performed by two teams: a professional motorsport extrication team and a team of professional emergency medical technicians (EMTs). Two different microelectromechanical systems were used to measure spinal motion, and a motionscore was calculated to compare the amount of remaining spinal motion. A high motionscore indicates high remaining motion and a low motionscore indicates low remaining motion. The use of an extricable seat results in a mean overall motion score of 1617 [95% CI 308-2926]. Emergency extrication without equipment resulted in the lowest overall motionscore 1448 [95% CI 1070-1826]. In case of urgent extrication the Extrication team attained a motionscore of 2118 [95% CI 517-3718] and the EMT team a motionscore of 2932 [95% CI 1427-4435]. When performing the procedure with the aid of a rescue boa, the EMT team achieved an overall mean motionscore in the same range 2725 [95% CI 568-4881] with boa vs. 2932 [95% CI 1427-4435] without boa. When mean scores of individual spinal segments were analyzed, we found that the EMT team did especially worse in immobilizing the cervical spine 198 vs. 758. Regular training of extrication procedures has paid off considerably in reducing spinal movement during extrication from a racecar. If an extricable seat is available, extrication should be performed using it. However, if emergency extrication is necessary, an additional manual cervical spine immobilization should be conducted using the Rautek maneuver to sufficiently reduce cervical spine movement.

The role of social workers in road traffic accident prevention communication for secondary school students in Danang City

Based on the analysis of the current status of road traffic accidents in Danang city and secondary schools in the area, the author analyzes the role of social workers in road traffic accident prevention communication for secondary school students. Most secondary school students are aware of the role of social workers in communication to prevent road traffic accidents and have made suggestions to improve the effectiveness of social work communication in preventing road traffic accidents for secondary school students in the study area.

Study of Pattern and Management of Abdominal Trauma Patients at a University Hospital of Nepal

Background: Injury related death is a leading cause of death globally. Abdominal injuries may occur in up to one third of patients with trauma. Road traffic accidents have become the commonest mechanism of trauma. Materials and Methods: This was a hospital based retrospective descriptive study conducted at Dhulikhel Hospital-Kathmandu University Hospital. Patients admitted with abdominal trauma from July 2021 to December 2023 were included in this study. Results: This study included 60 patients with abdominal trauma. Mean age of patients was 35.60 ± 15.81 (10-76) years. Majority of patients belonged to age group 21-40 years (n=32, 53.3%) with male predominance (Male:female ratio=3.6:1). Blunt abdominal trauma (n=58, 96.7%) was more common than penetrating abdominal trauma (n=2, 3.3%). Road traffic accident (n=31, 51.7%), fall from height (n=22, 36.7%) and physical assaults (n=7, 11.7%) were the mechanisms of injury. In our study, commonly injured organs were spleen(n=19, 30.64%), liver(n=15, 24.19%) and small bowel(n=14, 22.58%). Among the patients with penetrating abdominal trauma, one patient had rectal injury and next patient had stab injury with protruding omentum through the wound. Thirty four patients (56.7%) were managed conservatively and 26 patients (43.3%) underwent operative management. The mortality rate was 8.33% (n=5) of which 4 (80%) had undergone operative management and 1 (20%) was being managed conservatively. Conclusion: Majority of patients with solid organ injury can be managed conservatively while hollow viscus injury undergoes operative treatment. Physically active male population is the most affected group. Road traffic accidents are the leading cause of abdominal trauma followed by fall from height and physical assaults.

TIME SERIES MODELLING OF ROAD TRAFFIC ACCIDENTS IN WEST ARSI, ETHIOPIA

The aim of this research is time series modeling of road traffic accidents in the west Arsi zone, Ethiopia, it focused on monthly traffic accidents from January 2016 to December 2020. The goal of this study was to explore the number of traffic accidents to fit a time series model for the monthly number of road traffic accidents and to forecast a tow year ahead of the number of road traffic accidents. The analysis was done by using statistical software packages using this software and knowledge of time series analysis, trend, ACF, PACF, and Box-Jenkins analysis were computed. From the trend plot, the road traffic accidents was fluctuate from month to month as well as from year to year. There was total accident fluctuation from month to month (not stationary) a total of 1010 RTA were observed. The mean of 16.83 and standard deviation of 5.764 for the total accident was served the minimum and maximum record of road traffic accidents is 4 and 33 respectively. By differencing data one time, (2, 1, 3) model was fitted for making a two-year ahead forecast. Proper model adequacy checking was done. Two-year ahead forecasts showed that October, January, and April 2021 are the months with the most prominent values. Even if the trend in total accidents was decreasing there is still a need to pay more attention in order to prevent the occurrence of accidents related to road traffic accidents.

Effect of COVID-19 lockdowns on maxillofacial fractures in New Zealand: a retrospective study

Introduction: The New Zealand Accidents Compensation Corporation received 28,901 new claims for maxillofacial fractures between January 2018 and December 2021, at an annual cost of NZ$70–80 million. We have previously reported interpersonal violence as the most common cause of maxillofacial fractures disproportionately affecting young Māori males. This study provides an update on the incidence and cause of maxillofacial fractures with a specific review of the impact of COVID-19 lockdowns. Methods: Patients referred to the Wellington Regional Plastic, Maxillofacial and Burns Unit from 1 January 2018 to 31 December 2021 were identified from our maxillofacial fracture database. Age, ethnicity, gender, cause of injury, risk factors, and fracture pattern and management were analysed. Results: Out of 1281 patients identified, 75.2 per cent were male, most commonly (38.7%) aged 16–30 years. Interpersonal violence, falls and sports accounted for 37.6 per cent, 24.9 per cent, and 24.0 per cent of all maxillofacial fractures, respectively. Māori (22.0%) and New Zealand Europeans (55.7%) were the two largest groups, most commonly affected by interpersonal violence and falls, respectively. There was a relative increase in referral rates for females and for those older than 60 years (1.78 per 10 person-days versus 0.014 per 10 person-days and 4.2 per 10 person-days versus 1.8 per 10 person-days, respectively) and a decrease in the rates of interpersonal violence and sports related referrals (1.2 per 10 person-days versus 3.4 per 10 person-days and 0.41 per 10 person-days versus 2.19 per 10 person-days, respectively) during COVID-19 lockdowns, compared with outside lockdown. Conclusions: Interpersonal violence remains the main cause of maxillofacial fractures. There is a need for a national prevention strategy to reduce this. During COVID-19 lockdowns, there was a relative increase in the referral rates of females aged 60 years and over. Both sports and interpersonal violence showed significantly reduced referral rates during lockdowns, while falls, road traffic accidents and other were referred at a similar rate as out of lockdown.

Construction Technology for Roadbed and Pavement of Highway Bridge Settlement Section

In the transition area between highways and bridges, settlement often occurs. Even in the transition zone, small differences in settlement between bridge piers and embankments can easily lead to the occurrence of bridge head jumping events. Bridgehead jumping not only affects the comfort, speed, and safety of driving, but also creates a negative impression on the overall image of highways, shortening the service life of cars. At the same time, it can also affect the efficiency and availability of road traffic, and may even lead to traffic safety accidents. Based on an in-depth analysis of the settlement and deformation mechanism of highway bridge foundations, we have discussed the construction technology of road bridge settlement embankments.

Közúti közlekedési balesetben megsérült gyalogosok számának csökkentési lehetőségei

Összefoglalás. A közlekedési balesetekben sérült személyek, valamint a baleset miatti anyagi károk jelentős mértékű társadalmi-gazdasági veszteségértéket képviselnek. Kutatásommal célom a közlekedés biztonságosabbá tételéhez szükséges kulcsterületek feltárása és a lehetséges potenciális beavatkozási területek meghatározása volt. Munkám során a 2016–2020 közötti közlekedési balesetek adatait elemeztem leíró statisztikai módszerrel. Megállapítottam, hogy a leginkább kritikus pont a gyalogosok közlekedése. Azokban a balesetekben, ahol volt gyalogos sérült, a balesetek két okcsoportja dominál: gyalogosok hibája (34,3%), valamint a járművezetők gyalogosok részére történő elsőbbségadásának elmaradása (38,1%). Az eredmények lehetőséget adnak a további célirányos vizsgálatokra, valamint a hatékony beavatkozásokra. Summary. Transport is an essential part of everybody lives. The aim of transport users is to make their journeys without accidents in the shortest possible time, while optimising their individual resources and inputs. The number of people injured in road traffic accidents with personal injury and the material damage caused by a significant socio-economic loss. By preventing accidents, it is clear that the costs and resources spent on road accidents can be reduced. Therefore, I started my research by determining the share of road user groups in the number of accidents, the number of people injured and the amount of economic loss value associated with accidents. I analysed road accidents between 2016 and 2020. By the accident analysis, I found that among vulnerable road users, the proportion of pedestrians and cyclists injured was extremely high. Injuries in these two transport modes accounted for more than half of the injuries in cars. By calculating the loss value, I found that the damage to the national economy caused by pedestrian injuries was significant. In my research, by analysing the causes of accidents, I found that in accidents where there was a pedestrian injured, two groups of causes dominate: pedestrian error (34.3%) and drivers not giving priority to pedestrians (38.1%). Examining the accident data, it was evident that the number of pedestrian accidents due to pedestrian error is very high, so I continued my research in the area of other activities of pedestrians while walking. I measured pedestrians in 10 locations in Budapest. During the measurements, I recorded and analysed data of 11536 persons. The average rate of distraction was 54.3%, which means that one in two pedestrians is doing some other activity while walking. The most frequent activity was talking to another pedestrian (29.8%), but phone use (15.7%) and head/earphone use (13.5%) were also very significant. My research results so far show that if we want to improve pedestrian safety, we need to reduce accidents caused by pedestrians’ own fault and increase drivers’ willingness to give priority to pedestrians. My research plans also include investigating ways to reduce pedestrian errors, increasing pedestrian awareness and examining pedestrian-driver interactions in more depth. I already have results in this area, but my aim is to identify target areas (including human, infrastructure, vehicle field) for my research that can be implemented in practice, thus helping to improve pedestrian safety and road safety.
