Drivers driving safety on the highway is one of the important researches about the national road traffic safety, and how to reduce the high incidence of special sections accidents has always been the primary task of the research. When driving on the highway at night or in bad weather, drivers vision will be limited because of the poor light conditions and their recognition and perceptual speed of the road distance will be reduced, which will easily lead to major accidents. In order to solve this problem, the article introduces a new active light-emitting warning and guidance system which can automatically identify the field environment. After electrified, each grid will automatically set up the wireless network, and create a series of dynamic warning effects. It has been proved by field experiments that the developed system could stay in sleep mode during the day, and would be woken up at night or in rainy and foggy weather and automatically warned and guided the drivers driving on the road. The system will effectively enhance the drivers vision and reduce the accident probability.

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.

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 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 subject of this publication is the use of top-of-the-range driving simulators to study the impact of ITS services on the road safety. The aim of the article is to describe the assumptions of simulation studies carried out as part of the RID 4D project and to present the method of building research scenarios. The article discusses the catalogue of ITS services of the greatest importance to the Road Traffic Safety and traffic efficiency developed under the project. Then, services from the catalogue were specified, which were tested on the driving simulator of the Motor Transport Institute. The tests included sections of a dual-lane expressway. As a result of the work, four scenarios were created containing various dangerous events and variable message boards informing drivers about the danger and/or limiting the permitted speed. During the simulation, a set of several dozen parameters related to vehicle motion was recorded, in particular the distance to the vehicle ahead, time to collision with another vehicle or object on the road, speed, intensity of braking and acceleration. The tests were performed for good and bad weather conditions on a 60-person study group. The division into age groups 18-24, 25-50 and above 50 years was applied. The research showed a difference in the way drivers of static signs and speed limits on the variable message signs affect drivers. For variable messages signs, there was a greater decrease in speed than in the case of static signs.

Urban-rural ecotone is separate geographical unit, and it is in the parallel connecting area of the city and countryside. With the rapid economic development, traffic accidents in the area showing a significant increase in the trend. Because of vehicles in urban-rural ecotone of many types, traffic is more complex, speed variations and high frequency of speed changes, a greater impact on such sections of road traffic safety. Therefore, this article by the typical section of the survey, combined with the traffic simulation software, using grey relation entropy analysis method to analyze speed discrete of the urban-rural ecotone road, so as to clear the characteristics of various types of vehicles speed.
