F1000Research 2024, 13 :187 ( https://doi.org/10.12688/f1000research.139489.1 ) First published: 11 Mar 2024, 13 :187 ( https://doi.org/10.12688/f1000research.139489.1 ) Latest published: 11 Mar 2024, 13 :187 ( https://doi.org/10.12688/f1000research.139489.1 ) Introduction In 2018, 1.35 million people died due to crashes involving motor vehicles, most of which were young people between the ages of five to 29 years old, and the majority of victims were pedestrians, cyclists, motorcyclists, and animals. Most accidents occur in developing countries. 1 , 2 Accidents affect victims, both directly and indirectly. Direct effects include death, injury, loss of medical expenses, and property damage. Some indirect effects of road accidents include loss of income, changes in the mental health of the victim and those involved, and impact on the country’s business and society. 3 , 4 The global death toll from traffic accidents is increasing. Registration statistics indicate that vehicle incidents have increased annually. 5 Accidents directly and indirectly impact victims, their families, society, and the nation, as well as injuries, medical costs, and road safety campaign budgets. 3 According to the World Bank Country and Lending Groups, Thailand is a developing country with a middle-income 6 economy, which ranks first in Southeast Asia and eighth in the world for road fatalities, with an average of 32.7 deaths per 100,000 residents. 1 Road environments can contribute to this tragedy, which kills young adults worldwide. Thailand has one of the highest accident rates worldwide. 1 , 2 , 7 There have been reports of road traffic injuries and fatalities among 12–14-year-old children in the southern region of Thailand, resulting in severe disability and mortality, especially among those with pediatric traumatic brain injuries (TBI). 8 The most hazardous environment was rural roads with intersections. In rural areas, the accident rate is approximately 30%, 6% of all severe accidents. 5 The Haddon Matrix principle was devised to investigate accidents and road traffic injuries. It was evaluated from three vantage points: pre-event, event, and post-event phases, as well as three factors:1) human variables, 2) equipment/vehicle variables, and 3) environmental variables. 9 Fault tree analysis was used to analyze the risk of accidents to identify risk factors and the primary cause of public safety accidents by defining the potentially severe impact as the top event and identifying the fundamental event leading to a potentially powerful impact. For example, the evaluation of road accidents at the severity level that will impact catastrophe revealed the following risk factors:1) internal system failures, including battery failures, mechanical failures, and flight control system failures; 2) pilot factors, including unqualified knowledge and skills, poor safety awareness, violations, and lack of legal understanding; and 3) external environmental impacts, including obstacles, route planning issues, and unclear airspace. The Analytical Hierarchy Process (AHP) is also used to rank risky events to create a risk management plan that can be influenced by accidents. 10 , 11 The Haddon Matrix method classifies the causes of road incidents into three factors: driver behavior (41%), road environment (26%), and condition of the vehicle (33%). Males constituted a more significant proportion of road traffic casualties (RTCs) than females (61.39 vs. 38.61, P <0.05). The male mortality rate was 63.23 percent, with an average age of 33.65 and 16.76 years. Secondary school students had the highest morbidity and mortality rate (40.25%). Male adolescents are approximately three times more likely to experience road accidents than females, and mobile phone use while driving is typical at this age. 12 The percentage of individuals injured everywhere on their bodies (16.57%), upper or lower bodies (17.84%), skulls (20.77%), and abdomen (15.75%) varied considerably. 13 Road accidents are more common among drivers aged 17–25 years old. There is a correlation between severe accidents and excessive pace. Therefore, natural control measures exist. To prevent and reduce the number of casualties, stopping at intersections (T-intersections), controlling the road environment ( e.g. , the number of lanes, slope adjustment, and speed limit with a stop), traffic control devices, driver safety controls (age, gender, and speed), and prevention of accidents caused by natural disasters ( e.g. , providing weather forecasts and specifying the day and time of storms and rain) 14 are needed. This study investigates main road safety in Ubon Ratchathani Province, Thailand. A total of 17 Ubon Ratchathani town schools with routes to other districts were studied. It studied three pre-accident risk factors:1) in humans to analyze road user hazards to kindergarten and lower secondary students (6–15 years old). 2) Vehicle/equipment characteristics of cars that drive across the road in front of all ten schools. 3) How the school’s road environment may affect children’s ability to prioritize road risk mitigation actions. This study employed fault tree analysis and the analytic hierarchy process (AHP) to identify risk variables and road accident prevention techniques in the following order. Objective To assess the road accident risk factors for each event resulting in an accident on a school road. Methods The study design was approved by the Ethical Review Committee for Human Research, Ubon Ratchathani Rajabhat University (Study No. 015/2563-HE632027) on 7 March 2020. Written informed consent forms were completed by all participants. Study design and sampling A cross-sectional study utilized a checklist to effectively gather information for assessing the probability and risk of incidents on selected school main roads in Ubon Rattanathi, Thailand, from April to December 2020. We engaged stakeholders, including schoolteachers, community leaders, and parents of students, representing 17 schools. Our selection process focused on the main roads adjacent to those schools, involving 10 kindergartens to junior high schools in Ubon Rattanathi. There were 125 participants in the risk assessment model for road accidents near schools, and this assessment took place from April to December 2020. The study was conducted in three phases. The initial phase, spanning from April to May 2020, involved data collection from three schools: Ban Dampra School, Ban Thabor School, and Ban Namean School. Subsequently, the second phase took place from June to July 2020, during which data was gathered from three different schools: Ban Khamyai School, Ban Tungkunnoi-Nongjan Wittaya School, and Ban Pladuk School. The final phase, covering September to October 2020, involved data collection from four schools: Ban Yang Lum School and Ban Nonglai School. Following the completion of the data collection phases, three months were allocated for data gathering, culminating in data analysis conducted in November and December 2020 ( Figure 1 ). Figure 1. Map of the study area. Data collection for this study occurred at different times for various schools, potentially introducing temporal bias or seasonal variations. However, during data analysis, we addressed this concern by accounting for seasonal differences in traffic patterns and weather conditions. One potential issue with this study is selection bias since it focused on specific schools in the province of Ubon Rattanathi, Thailand, which may only be representative of regional schools. We selected schools with diverse characteristics and locations to minimize bias to ensure a more representative sample. We also addressed measurement bias by employing standardized incident reporting protocols and training personnel for data collection. To account for potentially confounding factors like traffic volume, speed limits, road conditions, and weather conditions, we used AHP with FTA-AHP analysis to adjust for their influence. Subgroup analyses were conducted to examine effect modifiers, such as whether the relationship between outcomes and exposure varied based on school type or other factors. Inclusion criteria and exclusion criteria Inclusion criteria included schools under the Ubon Ratchathani Primary Educational Service Area Office’s authority in high-risk areas and on main thoroughfares. Institutions not cooperating with the study during the research period were also excluded. The instruments and data collection The data collection instrument used in this study was derived from the Haddon Matrix, a highly acknowledged and influential framework in injury prevention. The matrix, developed by William Haddon in 1970, 15 analyses a range of factors related to individual characteristics, features of the vector or agent, and environmental variables before, during, and after an injury or fatality. Hence, the risk assessment form successfully identifies three distinct elements. The three categories considered in this study were as follows: 1) human/student, in humans to analyze road user hazards to kindergarten and lower secondary students (6–15 years old), 2) Vehicle/equipment characteristics of cars that drive across the road in front of all ten schools, and 3) the school’s road environment may affect children’s ability to prioritize road risk mitigation actions. These categories are derived from the Haddon Matrix. All 14 accidents underwent risk probability analysis and risk assessment for 10 roads based on the following factors: age, playing on the road, use of mobile phones, risk perception, vehicle/equipment, roadworthiness, lighting, braking, handling, environment, clear traffic signs, expressways, sidewalks, bus stops, school gates, and driving at excessive speeds. These accidents with similar characteristics were identified in a few studies. 5 , 16 , 17 Subsequently, a risk analysis was conducted, and risks were prioritized using the FTA-AHP technique in the following order. We conducted data collection activities from 2020 to 2022 by using a risk assessment approach for road accidents around schools. This assessment consists of three parts, which are information about students, vehicles/equipment, and the environment. Subsequently, the assessment was tested on a pilot group and implemented in a pilot school. Data from the pilot test was collected and feedback was used to make improvements during February 2020. Then, the assessment tool that had undergone quality checks was sent to experts for review in March 2020, before using it for risk assessment with a sample of 10 schools in the next phase. The risk assessment model for road accidents near schools, which has undergone quality checks, was used to assess the risk in 10 schools, namely: 1) Ban Dampra School 2) Ban Thabor School 3) Ban Namean School 4) Ban Khamyai School 5) Ban Tungkunnoi-Nongjan Wittaya 6) Ban Pladuk School 7) Ban Yang Lum School 8) Ban Nonglai School 9) Ban Huakam School and 10) Ban Phakaew School. This process was carried out in collaboration with the Education Committee in each school, including community leaders, community management committees, and school management committees, totaling 25 people. Therefore, there were 125 participants in the risk assessment model for road accidents near schools, and this assessment took place from April to December 2020. The first group of three schools collected data within the time frame covering April to May 2020. These particular schools encompassed Ban Dampra School, Ban Thabor School, and Ban Namean School. The second cohort of three schools gathered information from June to July 2020. The schools under consideration included Ban Khamyai School, Ban Tungkunnoi-Nongjan Wittaya School, and Ban Pladuk School. The final group of four schools that gathered data during a time frame covering from September to October 2020 consisted of Ban Yang Lum School and Ban Nonglai School. Following this, three months were allocated for data collection, which was later subjected to analysis during November and December 2020. Risk identification and FTA Fault tree analysis (FTA) quantifies a qualitatively identified risk from a relevant primary system as the top event in the tree for deductive reasoning based on risk factor probabilities. 16 , 17 FTA has considered three factors that cause school road traffic accidents: 1) Human/Student, such as age 6-15 years old, playing on the road, using a mobile phone, and risk perception; 2) Vehicle/Equipment, such as roadworthiness, lighting, braking, handling, and 3) Environment, such as clear traffic sign, motorway, sidewalk way, bus stop, school gates, driving at excessive speeds), The hazard conditions in front of 10 schools within a two-kilometer radius were recorded ( Figure 2 ). Figure 2. Fault tree model for school hazard identified. Risk impact with AHP The values of each factor were categorized into five ranks (very low, low, moderate, high, and very high) according to the value ranges encountered for each layer. Subsequently, the weight for each factor was estimated based on Saaty’s AHP 18 , 19 ( Table 1 ). The consistency index (CI) and the consistency ratio (CR) were calculated based on equation (1) in ( Figure 3 ). 18 , 19 Table 1. Analytic hierarchy process (AHP) Scale for Pairwise Comparisons. 19 Intensity of importance Definition Explanation 1-2 Equal importance Two activities contribute equally to the objective 3-4 Moderate importance Experience and judgment slightly favor one activity over another 5-6 Strong importance Experience and judgment strongly favor one activity over another 7-8 Very strong or demonstrated importance An activity is favored very strongly over another; its dominance demonstrated in practice 9 Extreme importance The evidence favoring one activity over another is of the highest possible order of affirmation Figure 3. The consistency index (CI) and the consistency ratio (CR) were calculated based on equations. The likelihood of each event was analyzed using the AHP technique of all ten schools with an expert choice program, RI=random index, and CR≤0.10 was considered acceptable, and the weights calculated for risk school road areas were considered statistically acceptable. Risk probability analysis with AHP with FTA-AHP The Analytic Hierarchy Process (AHP) were impact (I) and probability (P) from the FTA equation, which was obtained from equations 3 and 4 17 ( Figure 4 ).

Data processing and analysis The data 29 were validated and analyzed using the AHP technique of all 10 schools with the Expert Choice program version 11 to determine the chance of each event (Open source alternative: DecisionBuilderTM, Minitab). RI=random index and CR<0.10 was regarded satisfactory. The probability and impact rating of the risk assessment with a five-level risk matrix ( Tables 2 and 3 ) were based on the event’s probability. There are four risk score levels: negligible (1 to 5), tolerable (6 to 9), undesirable (10 to 16), and intolerable (17 to 25) ( Figure 5 ). 17 Table 2.

Risk scoring matrix. Results Probability and impact of each accident-causing incident on the school’s road. Using the FTA-AHP technique to analyze the likelihood of incidents in 10 areas, the study determined that the likelihood of an accident from each of the three main factors (Human/Student, Vehicle/Equipment, and Environment) is as follows: 1) The highest three rankings from Risk Perception in area SC 01,03, 02,05 for the effect of an accident involving human/student were 69.30%, 61.90%, and 57.4%, respectively. The highest three vehicle/equipment rankings for the likelihood of an accident were • 64.70 percent for Handling in the SC 01 area, • 61.90 percent for braking in the SC 07 area, and • 57.80 percent for lighting in the SC 03 area. The likelihood of an accident owing to the environment was 43.60%, 40.9%, and 40% in areas SC 01, 06, 03, and 09, respectively. The combined probabilities of the three primary factors, SC 01, SC 03, SC 02, and SC 05, had the greatest effects on humans/students (77.90%, 74.90%, and 73.40%, respectively). 74.90%, 74.90%, and 73.40% of SC 01, SC07, and SC06, respectively, were affected by vehicles or equipment. The cumulative effect on the environment in sectors SC 01, SC 07, and SC 06 was 100% (69.90, 69.30, and 69.10, respectively) ( Figure 6 ). Figure 6. The probability of each event that will cause an accident is a road around the school. FTA-AHP Risk Assessment Results In 10 schools, Human/Student (Risk Perception) and Environment (Driving at excessive rates) had the highest risk score of level 3 (Undesirable 10–16). 1) Lighting zone SC 03 (Ban Namean School), SC 04 (Ban Khamyai School), SC 05 (Ban Tungkunnoi-Nongjan Wittaya), SC 08 (Ban Nonglai School), SC 09 (Ban Huakam School). 2) Braking zone SC 07 (Ban Yang Lum School), SC 10 (Ban Phakaew School). 3) Handling zone SC 01 (Ban Dampra School), SC 02 (Ban Thabor School), SC 06 (Ban Pladuk School) ( Figure 7 , Table 4 ).

Depending on students and road users, it was found that for Human/Student, the highest probability was 77.90%, Vehicle/Equipment was 75.90%, and environment was 69.90% (found in area SC 01). The highest probability was found in 69.30% of risk perception, 64.70% of handling, and 43.60% of driving at excessive speeds, consistent with educational road traffic accidents, among the leading causes of injury and death worldwide. This resulted in a 100% risk of mortality and injury for road users, particularly for 81% of vulnerable road users and 36% of drivers. Accident-causing factors include human characteristics, vehicles, road characteristics, and environmental conditions, such as rush hour and school term time in the morning. 20 – 23 Transportation Research Information Services (TRIS) Transportation Research Information Services (TRIS) found human behavioral factors to be at the highest risk of road accidents at 41%, environmental factors at 26%, and vehicle factors at 33% (5). Behaviors can contribute to the risk of accidents, such as not crossing the road on a pedestrian crossing or a designated route and crossing during heavy traffic. Risky environmental factors are infrastructures such as sidewalks, zebra crossing, pedestrian-protected space at the exit, two-way streets, protected routes/corridors for pedestrian children, and 30 km/h zones. We also found that the density of cars in road environments with speed driving is a major factor causing accidents and the severity of the accidents. 24 – 26 According to this study, lack of road user safety awareness (69.30%), driving at high speeds in school zones (46.30%), and utilizing cars in incomplete situations ( e.g. , damaged) had the most significant impact on road accidents. Inadequate lighting on roads and vehicles was identified as an essential factor in road accidents, accounting for 57.80% of all incidents. Poor visibility owing to insufficient lighting can lead to increased risk for drivers and pedestrians. Braking issues accounted for 61.90% of road accidents. Problems with vehicle braking systems, such as worn-out brakes or delayed response times, can lead to collisions and a reduced ability to avoid accidents. Handling-related factors contributed to 64.70% of road accidents. Difficulties in maneuvering and controlling vehicles, particularly in emergencies, can increase the likelihood of accidents. Active school travel Personal safety, traffic safety, distance to school, school factors, and social factors are essential for student traffic safety, and we have analyzed the risk of road accidents and established proactive preventive measures in the area to reduce the risk of traffic on the road, including legislation to regulate driving speed and response to road infrastructure. Safe crossing measures are essential to protect students while walking across the roads, especially in nearby schools. This includes providing pedestrian crossings and designated routes with proper signage and traffic signals. Educating students about the importance of using designated crossings and following traffic rules is crucial to instilling road safety awareness from a young age. Ensuring a safe road environment for motorcycles and bicycles involves several aspects. First, establishing dedicated lanes and routes for bikes and motorbikes can separate them from faster-moving vehicular traffic, reducing the risk of collisions. 23 , 27 In addition, the government should support road safety through public education.

Strict enforcement of the law, especially regarding driving faster than the law, and improving the road environment is considered safer to ensure road user safety. 28 Conclusion The FTA-AHP technique was selected for the study on the school’s main highways in the Ubon Ratchathani Province of Thailand. In terms of human/student (Risk Perception), environment (driving at excessive speeds), and vehicle/equipment (Lighting, Braking, Handling), the highest risk score was level 3. The area surrounding SC01 had the highest accident probability for all 10 schools owing to risk perception (69.30%), handling (64.70%), and driving at excessive velocities (43.60%). Human/student (77.90%), vehicle/equipment (75.90%), and environment (69.90%) had the most significant influence in area SC 01. Therefore, it is necessary to prevent or reduce the risk of road accidents. First, road users must be aware of risks and adhere rigorously to traffic regulations. Regarding traffic knowledge, a safe road environment, and strict adherence to traffic laws, schools, communities, and government organizations must support them.

Continue reading READ ALL According to the title, the manuscript describes the risk assessment by applying the fault tree analysis and analytic hierarchy process in rural areas of Thailand. Partly due to language issues, the manuscript is not easy to read and understand, especially regarding the fault tree analysis and analytic hierarchy process. It is unclear how to use both fault tree analysis and analytic hierarchy process. Why did the authors choose to use those tools? However, this study has many good and important aspects, but the manuscript needs some major, but I view, very “do-able” revisions. Title Please specific the study area in the title. It's too spacious for rural areas. Abstract Please adjust the writing of the introduction to be consistent with what you want to study. Please check typo error entire the manuscript. Authors need to determine the factors for assessing the risk. Please rewrite of the methods section. The authors should explain the details of study. Fourteen sub-criteria? What are the main criteria? “RI (random index) was calculated” This sentence is not correct. Please revise it. The conclusion should not be written in duplicate with the results of the study. This “traffic accident” does not reflect research study. The FTA-AHP techniques duplicated with Analytic Hierarchy Process. Introduction Lack of explanation on the area of study and the issues/problems. The authors need to elaborate more on the issues towards road traffic accident at school. Please support the road traffic accident at school with citations or literature sources when elaborating the aspects. This is important step to find out the gap of research. Due to language issues, the manuscript is not easy to read and understand. Please send the manuscript to a native speaker to check before submission. What are the advantage and disadvantage of using AHP? Why did the authors choose the fault tree analysis? Please provide supporting reasons. Objective Please adjust the objective to be consistent with the research title. Methods Where does the checklist form come from? Who made it? Please give details. Please add more details of FTA and AHP including risk assessment How does the authors prove the FTA diagram? Please add the details The method for doing AHP should be explained in detail. In the case where there are many evaluators, what is the method for doing it? Please add the reference in Table 3 and Figure 5. “Figure 5 Risk scoring matrix” This is a table, not a figure. Please give the meaning the risk class; negligible 1-5; Tolerable 6-9; Undesirable 10-16; Intolerable 17-25. Results Please give an example of manual calculation for AHP. Please show the results from Expert Choice program. Discussion The results should be discussed in the section FTA; AHP and risk assessment. The discussion part should not be written in duplicate with the results of the study. Authors must first discuss the study's findings and then explain how the study's results are similar or different from other studies. Conclusion The conclusion should not be written in duplicate with the results of the study. References Harmonize format with F1000Research style requirements. Is the work clearly and accurately presented and does it cite the current literature? Partly Is the study design appropriate and is the work technically sound?

Continue reading READ ALL The study's conclusions and suggestions may influence and enhance safety protocols, legislative choices, and instructional programs, thereby lowering the chance of traffic accidents and fostering a safer atmosphere for communities and students. The scholars' commitment to this significant subject is really admirable! Description about significance of study: The Haddon Matrix and other methods were utilized in a study on traffic accidents near schools in Ubon Rattanathi, Thailand, in order to identify and evaluate risk factors.The study discovered that the biggest risk factors were human perception of risk, the environment (particularly speeding), and problems with vehicles and equipment, with human conduct accounting for the most important portion (77.90%). The survey also found that utilizing defective vehicles, speeding in school zones, and a lack of safety knowledge were key causes of accidents. These results are consistent with earlier studies that found behavioral aspects of human conduct to be the greatest risk factor (41%), followed by environmental and vehicle components. Comments: 1. The writers skipped over 'accidents' in the title. (The title could be changed to: Risk assessment of Road accidents in rural Thailand: A fault tree analysis) 2. The authors have describes ''The most hazardous environment was rural roads'' - So, why they have conducted this study in urban settings ''involving 10 kindergartens to junior high schools in Urbon Rattanathi'' and not in rural roads? 3. Please explain why was a variable not included in the FTA hierarchy. 4. Please find spelling mistakes such as: (Ubon=Urban; Risk Risk level of school=Risk level of School) 5. The last 2 lines of the conclusion give recommendations for the drivers and not for the environmental changes which can reduce accidents 6. The study design is appropriate, and suitable for the research question or objective. Is the work clearly and accurately presented and does it cite the current literature? Yes Is the study design appropriate and is the work technically sound? Yes Are sufficient details of methods and analysis provided to allow replication by others? Yes If applicable, is the statistical analysis and its interpretation appropriate? I cannot comment. A qualified statistician is required. Are all the source data underlying the results available to ensure full reproducibility? Partly Are the conclusions drawn adequately supported by the results? Yes Competing Interests: No competing interests were disclosed. Reviewer Expertise: Public Health I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.

Not approved Fundamental flaws in the paper seriously undermine the findings and conclusions According to the title, the manuscript describes the risk assessment by applying the fault tree analysis and analytic hierarchy process in rural areas of Thailand. Partly due to language issues, the manuscript is not easy to read and understand, especially regarding the fault tree analysis and analytic hierarchy process. It is unclear how to use both fault tree analysis and analytic hierarchy process. Why did the authors choose to use those tools? However, this study has many good and important aspects, but the manuscript needs some major, but I view, very “do-able” revisions. Title Please specific the study area in the title. It's too spacious for rural areas. Abstract Please adjust the writing of the introduction to be consistent with what you want to study. Please check typo error entire the manuscript. Authors need to determine the factors for assessing the risk. Please rewrite of the methods section. The authors should explain the details of study. Fourteen sub-criteria? What are the main criteria? “RI (random index) was calculated” This sentence is not correct. Please revise it. The conclusion should not be written in duplicate with the results of the study. This “traffic accident” does not reflect research study. The FTA-AHP techniques duplicated with Analytic Hierarchy Process. Introduction Lack of explanation on the area of study and the issues/problems. The authors need to elaborate more on the issues towards road traffic accident at school. Please support the road traffic accident at school with citations or literature sources when elaborating the aspects. This is important step to find out the gap of research. Due to language issues, the manuscript is not easy to read and understand. Please send the manuscript to a native speaker to check before submission. What are the advantage and disadvantage of using AHP? Why did the authors choose the fault tree analysis? Please provide supporting reasons. Objective Please adjust the objective to be consistent with the research title. Methods Where does the checklist form come from? Who made it? Please give details. Please add more details of FTA and AHP including risk assessment How does the authors prove the FTA diagram? Please add the details The method for doing AHP should be explained in detail. In the case where there are many evaluators, what is the method for doing it? Please add the reference in Table 3 and Figure 5. “Figure 5 Risk scoring matrix” This is a table, not a figure. Please give the meaning the risk class; negligible 1-5; Tolerable 6-9; Undesirable 10-16; Intolerable 17-25. Results Please give an example of manual calculation for AHP. Please show the results from Expert Choice program. Discussion The results should be discussed in the section FTA; AHP and risk assessment. The discussion part should not be written in duplicate with the results of the study. Authors must first discuss the study's findings and then explain how the study's results are similar or different from other studies. Conclusion The conclusion should not be written in duplicate with the results of the study. References Harmonize format with F1000Research style requirements. Is the work clearly and accurately presented and does it cite the current literature? Partly Is the study design appropriate and is the work technically sound? No Are sufficient details of methods and analysis provided to allow replication by others? Partly If applicable, is the statistical analysis and its interpretation appropriate?
