The article shows the essence of road safety in the Lubelskie Voivodeship on the example of two longest and most dangerous No. 19 and 74 national roads running through the voivodeship. The article aims to diagnose the current state of road safety in the Lubelskie Voivodeship and identify opportunities for its improvement. The statistical data of the Central Statistical Office in Lublin, annual reports on road accidents of the Police Headquarters in Warsaw, reports of the National Road Safety Council, and documents of the General Directorate for National Roads and Motorways Branch in Lublin were used to analyze the safety. The analysis of the statistical documents allowed the conclusion that ten national roads run through the Lubelskie Voivodeship. Roads No. 9, 17, and 74 are the longest ones. However, on a national scale, roads No. 19 and 74 are of great importance to road safety. It has been observed that the number of road accidents in the Lubelskie Voivodeship is decreasing year by year; thus, the number of accident victims is also falling. The national road No. 19 remains the most dangerous. Passenger car drivers most frequently caused road accidents since they did not adopt the speed to road conditions or obey the right of way. The Provincial Road Safety Improvement Program in Lublin assumed a significant reduction in the number of victims killed and injured on the roads. Unfortunately, after analyzing the statistical data over the years, it can be stated that even though the assumed goal was not achieved, the accident victim rate improved.

Abstract Analysis of road traffic accidents revealed that most accidents are as a result of drivers’ errors. Over the years, active safety systems (ASS) were devised in vehicle to reduce the high level of road accidents, caused by human errors, leading to death and injuries. This study however evaluated the impacts of ASS inclusions into vehicles in Nigeria road transportation network. The objectives was to measure how ASS contributed to making driving safer and enhanced transport safety. Road accident data were collected, for a period of eleven years, from Lagos State Ministry of Economic Planning and Budget, Central Office of Statistics. Quantitative analysis of the retrospective accident was conducted by computing the proportion of yearly number of vehicles involved in road accident to the total number of vehicles for each year. Results of the analysis showed that the proportion of vehicles involved in road accidents decreased from 16 in 1996 to 0.89 in 2006, the injured persons reduced from 15.58 in 1998 to 0.3 in 2006 and the death rate diminished from 4.45 in 1998 to 0.1 in 2006. These represented 94.4 %, 95 % and 95 % improvement respectively on road traffic safety. It can therefore be concluded that the inclusions of ASS into design of modern vehicles had improved road safety in Nigeria automotive industry.

Analysis of Factors Influencing the Density of Fatalities on National Roads in PolandIn Poland 20% of the total number of accidents occur on the national roads, which constitute 7% of the length of all roads. In the case of fatalities this share is significantly higher as it constitutes up to 36% of the total casualties. In accordance with the EU Directive (Journal of Laws EU L. 319/59) the level of road traffic safety should be raised by targeting investment on the most dangerous road sections. Finding the dependence between road and traffic factors and the number of accidents and casualties of road accidents may be helpful in predicting safety levels and selecting road traffic safety improvement measures. The paper presents the experience of other countries and preliminary tests results of the impact of the selected factors on the density and the number of road accident fatalities on the national roads in Poland.

Crash Tests

The reliable speed of a vehicle, assigned to a given road arc, is not usually taken into account in simulation of crash tests on road safety barriers located on horizontal concave arcs with small radii (20−200 m). In this work, the numerical modelling and simulations of TB11, TB32 crash tests for selected road safety barriers on a horizontal concave arc with a small radius of 150 m, at a reliable and increased speed of a vehicle, were conducted. The authors developed the methodology of numerical modelling and simulation and published in the period 2015−2018. In this study, crash tests include two N2 class steel road barriers with the B-type guide rail, i.e. SP-05/1 (with 1.00 m post spacing) and SP-05/2 (with 2.00 m post spacing). Suzuki Swift and Dodge Neon vehicle models were taken from the National Crash Analysis Center (USA) library and modified, respectively. It was proved that road traffic safety on horizontal concave arcs with small radii is assured if the reliable velocity is not exceeded by drivers. Compacting the post spacing or the uses of a composite-foam protective overlay added to guide rails are not recommended.

Stable and slidable roofs of the semitrailers are usually characterized by low weight and easy handling, which equals directly into comfort of use, longevity of the system and the time needed to open or close. However, not always an operational advantages of roofs go hand in hand with their durability, especially in the snowfall situation or sudden changes of the road lane by a set of vehicles: a truck tractor – a semitrailer. The analysis of homologation regulations shows that today there are no precise requirements and physical testing / strength methods for assembled roofs of the semitrailers as components. The test methods for complete vehicle bodies (including the roof), which have destructive nature, are described in European standards, e.g. EN 12642:2017 "Securing of cargo on road vehicles – Body structure of commercial vehicles – Minimum requirements" [6], internal German regulations, e.g. VDI 2700:2004 "Securing of loads on road vehicles" [8] or Directive DCE 9.5:2008 ”Load security for transportation of load containers on utility vehicles in road traffic” [7]. A non-destructive, possible to perform, testing method for the roof as a component - is calculation method. The results of the performed tests allow to conduct development works over improving the vehicle’s system security (including the introduction of new semitrailers roofs design solutions and verification of existing ones). The carried out strength tests give possibilities to optimize and adapt the roofs to the transported loads, e.g. stable lifting roofs used in transport of divisible loads, or sliding roofs used in the transport of non-separate loads. The strength testing of the semitrailer’s roofs is highly justified from the point of view of securing the load and safety of passengers, drivers and other road users primarily. The requirements and limitations of the mentioned testing methods are not - in the authors opinion - 100% of realistic and possible deformation during the real vehicle’s road traffic. On the other hand, the cited documents exists as recognized regulators in the international arena of the road traffic legislation. The work’s aim is demonstrating the benefits of using reinforced roofs in all types of the semitrailer’s bodyworks.

Purpose The purpose of this paper is to perform fine classification of road traffic visibility based on the characteristics of driving behavior under different visibility conditions. Design/methodology/approach A driving simulator experiment was conducted to collect data of speed and lane position. ANOVA was used to explore the difference in driving behavior under different visibility conditions. Findings The results show that only average speed is significantly different under different visibility conditions. With the visibility reducing, the average vehicle speed decreases. The road visibility conditions in a straight segment can be divided into five levels: less than 20, 20-30, 35-60, 60-140 and more than 140 m. The road visibility conditions in a curve segment can be also divided into four levels: less than 20, 20-30, 35-60 and more than 60 m. Originality/value A fine classification of road traffic visibility has been performed, and these classifications help to establish more accurate control measures to ensure road traffic safety under low-visibility conditions.

Abstract Although the occurrence of road accidents and the number of road accident casualties in almost all Polish voivodeships has decreased over the last few years, the rate of this change varies considerably from region to region. To provide a better understanding of such a tendency, panel data regression models are proposed to conduct this pilot research which evaluates the relative performance of Polish regions in terms of their road traffic safety. Panel data are multi-dimensional data which involve measurements over time. In the research, a voivodeship is a unit analysed at a group level, whereas a year is a unit analysed at a time level. A two-way error component regression model has been applied to survey the impact of regressors, the group effects, and time effects on a dependent variable. The analysis has been conducted using data acquired from the Statistics Poland Local Data Bank website, as well as from the General Directorate for National Roads and Motorways. The panel data from 16 regions in Poland and the 2012–2018 period have been investigated. The examined models refer to road traffic safety indices defined based on the following characteristics: the number of road accidents, the number road fatalities, and the number of people injured. The results of all the three models indicate a negative effect as regards the GDP per capita, (car) motorisation rate, the indicator of government expenditure for current maintenance of national roads, and the road length per capita. A positive association has been found between the truck motorisation rate and the indicator of local government expenditure on roads. The impact of the region's urbanisation indicators on road safety is ambiguous as, on the one hand, its increase causes a reduction in the road accident and accident injury indices, but, on the other hand, it produces a rise in the accident fatality index. In the models, the significance of time effects has been identified; a decreasing time trend suggests a general improvement in road safety from year to year. Most of the group effects have turned out to be highly significant. However, the effects differ as regards both the road accident and the accident injury indices in magnitude and direction.

Abstract The highest number of road accidents occurs at junctions. One of the aims of traffic organisation is to improve traffic safety in these areas. Based on a variety of indices – road capacity, points of conflict, number, and severity of road traffic accidents – different alternatives for junctions are evaluated. However, the road network has many junctions and roads serve to travel from point "A" to point "B" at a given time. Therefore, one of the most important tasks when addressing the issue of road safety is to find a rational way of improving the safety without losing the importance of the road. The aim of this paper is to analyse the impact of different junctions on the road network and basing on actual data develop a method for the evaluation of different types of junctions with respect to road class.
