“…In the period from 2000 to 2015, traffic accidents increased significantly by 7.65 per year (95% CI: 5.7 to 9.6), representing 75.58% of traffic accidents, which probably may be due to the average increase of 8.08% of the vehicle fleet in Ecuador in those years [65,66], non-compliance with traffic law, vehicles with little or no safety equipment. As of 2016, they decreased by −8.54 per year (95% CI: −20.2 to 4.9), with 24.2% of the total number of traffic accidents; this decrease can probably be attributed has the reform of the land transport law regulation [67], in addition to the investment in road improvement, construction, and reconstruction [68], since these types of investments positively affect traffic accidents according to Calvo-Poyo study [69]. Likewise, the increase in breathalyzer tests for drivers and the implementation of computerized radars [70] have been part of the state surveillance program, which was demonstrated as a very effective measure to improve road safety in other countries.…”

Background: Road safety is a significant public health problem because it causes negative consequences on victims and families. The objective was to analyze the most significant changes in traffic crashes in Ecuador during the period from 2000 to 2019. With data obtained from the National Institute of Statistics and Census, we performed the analysis to identify: the number of traffic crashes, the number of victims, and other study variables. Methods: Descriptive and analytical statistics and the contrast of proportions were used to analyze data from 2000 to 2019. Results: According to the ideal joinpoint analysis model, there was a significant decrease in the number of recorded traffic accidents from 2015 to 2019 of −8.54 per year, while the tendency to die increased in females (2.05 per year) and males (3.29 per year). The most common crash was a collision, and the automobile appeared as the most involved vehicle from 2015 to 2019. The hypothesis test contrast is used to determine if statistically significant differences exist between age groups by gender of the driver injured in the period 2017–2018. Conclusions: This study determines the most significant changes in the variables related to traffic crashes, where mortality due to this cause in the last four years has had a growth rate of 1.8% compared to collisions that presented a rate of −31.12%. The contrast of the hypothesis test shows significant differences in the injury level between males and female drivers, depending on the age group.

“…The total number of traffic accidents in the CZ increased throughout the last monitored period (2018) by nearly 3% (from 21,263 to 21,889), while over the last five years (2014-2018), this value has more or less stagnated [1]. Globally (year 2018), road traffic accidents are the eighth most common cause of unnatural death among people of all ages, however, it is the number one cause of death for the population from 5 to 29 years old [2]. In the same year, the number of cargo vehicle accidents in the CZ was a total of 11,542, representing nearly 53% of all traffic accidents [3].…”

Improvement of Road Safety through Appropriate Cargo Securing Using Outliers

The article focuses on evaluating a transportation experiment that intends to improve road safety by analyzing transport shocks that significantly affect the system of securing the load, vehicle, driver, and other aspects. Within Europe, improper or insufficient securing of loads causes up to 25% of all cargo vehicle accidents. Our transport experiment consists of eight rides of a Tatra truck. The measured values of shocks (acceleration coefficients) are statistically evaluated. Three hypotheses are established for these purposes. First, it is proven that the probability distributions of the shocks values differ statistically significantly among individual rides, namely in their shape and median value. Thus further statistical analyses are performed separately for the individual rides, axes, and the accelerometer locations. These analyses prove significant exceedances of the normatively set limits given by the EN 12195-1:2010 standard, which is potentially risky. Especially for the z axis and y axis, the set 20% limit was exceeded in 75.0% and 56.3% of cases, respectively. In the case of the x axis, the established 20% limit was practically not exceeded at all. The analysis of exceeding the permitted limits (the statistical evaluation of the second and third established hypothesis) is based on boxplots that graphically describe the individual rides, as well as on the found contaminated log-normal distribution of the values of the acceleration coefficients in the individual rides. The last hypothesis regarding exceeding the double value of the permitted limit is rejected. Methods of statistical comparison are used during data analysis. The probability distribution of acceleration coefficients is modeled using a contaminated log-normal distribution.

“…Road accidents are demonstrated to be one of the major sources of injuries and fatalities worldwide [ 1 , 2 , 3 , 4 ]. Every year, more than 1.24 million people die on the road, and 50 million people suffer non-fatal injuries [ 5 ].…”

Official statistics demonstrate the role of traffic accidents in the increasing number of fatalities, especially in emerging countries. In recent decades, the rate of deaths and injuries caused by traffic accidents in Iran, a rapidly growing economy in the Middle East, has risen significantly with respect to that of neighboring countries. The present study illustrates an exploratory spatial analysis’ framework aimed at identifying and ranking hazardous locations for traffic accidents in Zanjan, one of the most populous and dense cities in Iran. This framework quantifies the spatiotemporal association among collisions, by comparing the results of different approaches (including Kernel Density Estimation (KDE), Natural Breaks Classification (NBC), and Knox test). Based on descriptive statistics, five distance classes (2–26, 27–57, 58–105, 106–192, and 193–364 meters) were tested when predicting location of the nearest collision within the same temporal unit. The empirical results of our work demonstrate that the largest roads and intersections in Zanjan had a significantly higher frequency of traffic accidents than the other locations. A comparative analysis of distance bandwidths indicates that the first (2–26 m) class concentrated the most intense level of spatiotemporal association among traffic accidents. Prevention (or reduction) of traffic accidents may benefit from automatic identification and classification of the most risky locations in urban areas. Thanks to the larger availability of open-access datasets reporting the location and characteristics of car accidents in both advanced countries and emerging economies, our study demonstrates the potential of an integrated analysis of the level of spatiotemporal association in traffic collisions over metropolitan regions.
