On The Road

The main focus of this article is on the road traffic safety development trends in Latvia. Soon after the regain of independence at the beginning of the 1990s, road traffic safety characteristics in Latvia were the worst in the Latvian history. The increase of car availability and affordability made the car a major road vehicle. The implementation of road safety programmes contributed to essential improvement of road traffic safety in Latvia. The number of road accident fatalities in 2020 compared to 1991 decreased more than sevenfold. Nevertheless, the current Latvian road traffic safety statistics is well below the average level of the EU member states and even the pandemics did not cause similar reduction as in most member states. This indicates that great improvement is still needed. The article shows the Latvian experience in road traffic safety enhancements and discusses the measures to improve road traffic safety.

The Impact

The article presents the analysis of the performance of the vehicles equipped with automated driving systems (ADS) which were tested in real-life road conditions from 2015 to 2017 in the state of California. It aims at the effort to assess the impact on the road safety the continuous technological advancements in driving automation might have, based on of the first large-scale, real-life test deployments. Vehicle manufacturers and other stakeholders testing the highly automated vehicles in California are obliged to issue yearly reports which provide an insight on the test scale as well as the technology maturity. The so-called 'disengagement reports' highlight the range and number of control takeovers between the ADS and driver, which are made either based on driver's decision or information provided by the vehicle itself. The analysis of these reports allowed to investigate the development made in automated driving technology throughout the years of tests, as well as the direct or indirect influence of the external factors (e.g. various weather conditions) on the ADS performance. The results show that there is still a significant gap in reliability and safety between human drivers and highly automated vehicles which has been yet steadily decreasing due to technology advancements made while driving in the specific infrastructure and traffic conditions of California.

AbstractThe article presents the application of the GWR (Geographically Weighted Regression) model to the description of differences in the level of road traffic safety in individual counties on the example of the Kuyavian-Pomeranian Voivodeship. The GWR model developed for counties, taking into account the diversity of NUTS 3 regions, can be a helpful tool for traffic safety management in voivodships and lower administrative units, and such an approach has not yet been applied.

The Impact

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.

The Eu

The European Parliament and the European Council have adopted the Directive 2008/96/EC relating to the safety of traffic infrastructure. This Directive binds the EU Member States to implement the guidelines on roads comprising the parts of the Trans-European traffic network, regardless of the stage those roads are in. EU Member States have a possibility to adopt the guidelines and regulations from the Directive and build them into the national regulations on parts of the roads that are not a part of the Trans-European roads. Based on the facts stated above, there is a research problem in a form of a question “Can the Directive 2008/96/EC be applied in the traffic in Bosnia and Herzegovina?” i.e. are its guidelines implemented as a manner of approximation with the EU regulations, and what are the effects of its implementation. This is a traffic problem in its nature, closely related to road traffic safety, and we find the answer to the research problem in theoretical and empirical research in this area.

Road Traffic Safety

Various traffic safety efforts that aimed to reduce the number of traffic accident victims on road. Traffic safety is a program to reduce the number of accidents either the consequences. Tendency of road accident causes are human factor, therefore is needed a system approach to handle traffic safety that include four aspects, that is 1) Process; 2) Infrastructure; 3) Management; 4) Coordination and integration. Safer road can not be achieved if only just using the strategy, but the capacity of institution is needed by coordination and integration amongst the ministries of the institution. Coordination and integration as a form of synergy among the ministries of the institution to handle the road safety conducted by sharing the role to handle various road safety related areas by using the Information Resources Information System – IRIS. Berbagai upaya keselamatan lalu lintas yang bertujuan menurunkan korban kecelakaan lalu lintas di jalan. Keselamatan lalu lintas merupakan suatu program untuk menurunkan angka kecelakaan beserta seluruh akibatnya. Kecenderungan penyebab kecelakaan lalu lintas adalah faktor manusia, sehingga diperlukan pendekatan sistem dalam penanganan keselamatan jalan yang mencakup empat aspek, yaitu: 1) Proses; 2) Infrastruktur; 3) Manajemen; 4) Koordinasi dan integrasi. Keselamatan jalan tidak dapat terwujud hanya dengan menggunakan strategi, namun dibutuhkan kapasitas kelembagaan melalui koordinasi dan integrasi antar kementerian lembaga. Koordinasi dan integrasi sebagai wujud sinergitas antar kementerian lembaga dalam penanganan keselamatan jalan dilakukan dengan berbagi peran dalam menangani berbagai bidang yang terkait keselamatan jalan dengan menggunakan sistem informasi sumber daya informasi (Information Resources Information System-IRIS).
