The Impact

The social cost, as one of the factors determining sustainability of socio-economic development, is strongly dependent upon a number of casualties and mortality in road accidents. The condition of car tires appears to be one of the important factors determining the occurrence of accidents. The vast majority of vehicles are tested every year at vehicle inspection stations. One of the elements affecting the result of the technical condition test and basically the quality of vehicle braking is the technical condition of the tires. Their technical condition is a very important factor responsible for the quality of acceleration, braking, maintaining, or changing the direction of driving. As a consequence, it has a significant impact on road safety. The aim of the study is to examine the impact of tires on the results of tests performed at a vehicle inspection station. The study presents the results of bench measurements of the impact of selected features of tire condition of two vehicles during routine periodic inspections at a vehicle inspection station (VIS). The focus was on an attempt to assess the impact of inflation pressure, age, and tire tread wear on the braking process. The technical studies performed might be a source for legal steps assuring better management of road safety. It can also be expected that the tire choice and condition may affect fuel consumption, and therefore the amount of energy consumed by the road transport.

Different Levels

In a strategic document of EU for Road safety improvement, up to 2030, "safe vehicle" is recognized as one of the pillars of a stable Road safety system. The part of the "safe vehicle" pillar is technical vehicle ispection, where parameters important for road safety are periodically checked. The aim of this work is to determine the quality of the measurement data and the ability to repeat measurements of some parameters during technical vehicle inspection, or more precisely, to determine whether measured data of turning wheel resistance and brakes ovality differ depending on the inspection place. The research is done by inspecting ten vehicles at five inspection places with different levels of resources use. The results show that the spread of measured data of turning wheel resistance is statistically significant and that it depends on the inspection place, as well as that measured data of turning wheels resistance significantly vary between inspection places. The measured percentage of brakes ovality is different from one inspection place to another, but the differences are statistically significant only for right wheels. The impact of inspection place, although less than in turning wheel resistance measurement, is still significant.

The Impact

The article is an attempt to present the two modern concepts of safety management systems. The first is the sunflower pyramid used especially in Europe, the second is the ISO 39001 standard (Road Safety Management System) of international scope. The idea and possibilities offered by use of both concepts of safety management, as well as an attempt to assess the impact of their actions on decrease in fatalities in selected EU countries, were presented. As a result of the conducted analyses, a downward trend was noted as to the number of certificates issued for compliance with the ISO 39001 standard in the world, which may indicate an appearance of the more adequate management systems, or other tools or concepts to improve the road safety, or inadequate education society and low level of awareness in this area of stakeholders, including politicians, scientists, producers, drivers (professional and reliable), as well as other road users, including unprotected ones.

Transport Safety

The road safety management methodology should be based on a system approach. This means that the road transport must be formalized as a complex system (CS), and then safety can be interpreted as an emergent feature of such a system. Road accidents should be interpreted as "organizational accidents". They should be studied using concepts such as "normal accident theory" (NAT) and "highly reliable organization" (HRO). The main purpose of the article is to show the usefulness of these concepts for the road safety and risk management, especially in Polish conditions. The system approach to road safety research (and transport safety) will allow for the better safety results.

Directive 2008/96/EC on road infrastructure safety management requires the establishment and implementation of procedures relating to road safety impact assessments (RSIA), road safety audits (RSA), ranking of high accident concentration sections and network safety ranking (NSR) and road safety inspections (RSI). The aim of this article is to present the outputs of BALTRIS project. The goal of the international project BALTRIS is to elaborate the road and street infrastructure safety management procedures and teaching material consistently explaining the above mentioned infrastructure management procedures. Four Baltic Sea region countries (Sweden, Estonia, Latvia, and Lithuania), represented by universities and national road administrations participate in the elaboration of these procedures and teaching material. This article describes the scope of NSR, RSA and RSI procedures prepared in the frame of BALTRIS project, also article provides detailed implementation and execution of procedures for the EU Member States. NSR means a method for identifying, analysing and classifying parts of the existing road network according to their potential for safety development and accident cost savings. Ranking of high accident concentration sectionsmeans a method to identify, analyse and rank sections of the road network which have been in operation for 3÷5 years and upon which a large number of fatal/injury accidents in proportion to the traffic flow or compared to respective conditions have occurred. RSI is a strategic comparative analysis of the impact of the new road or a substantial modification to the existing network on the safety performance of the road network. RSA is a formal safety performance examination of the existing or future road or intersection by an independent audit team.

Based on literature data, the paper analyzed the impact of transport operational indicators related to the quality of road surface coverage on road safety. It presented the results of experimental studies on the effect of the road adhesion cationic thermostable additive on the properties of bitumen and asphalt concrete. The authors identified that the introduction of this additive leads to an increase in the viscosity and softening temperature of bitumen, its adhesion to mineral materials, which has a positive effect on strength, water resistance, shear stability, crack resistance, fatigue durability of asphalt concrete. The conclusion was made about the regularity of improving road safety, related to the improvement of the quality of the pavement, arranged from asphalt concrete with the application of the tested additive.

Abstract In Poland, road inspections were implemented in June 2014 on all national roads. Previous traffic surveys mainly looked at the technical condition of roads, signs and markings; other safety issues were overlooked. The main problem of the inspections is that the qualitative assessment is subjective which affects the classification of the sources of hazard on the road. The paper presents an analysis of the variability of the qualitative assessments of road defects when they are assessed by different teams of inspectors. On this basis, guidelines were developed for the classification of risks based on the relationship between sources of road hazard and the personal and economic losses involved in road accidents. These relationships are quantified using mathematical models to simulate the effect of hazard variability on the consequences of selected road accident causes on sections of the road network.

Analysis of regional accident records shows that a country’s national road safety programme does not have the same effect in each of its regions. What may be a serious problem in one region may be of marginal significance in another. Polish and international experience shows that main risk groups and types of accidents related to the level of development and quality of the road network differ from region to region. The conclusion is that a centrally run road safety policy does not always produce the expected outcomes. This suggests that more can be achieved with a combination of strategic (national) road safety management and tactical (regional) and operational (local) road safety efforts. Poland’s regional road safety programmes were found to lack an analysis of the effects of selected factors on safety or fatality forecast based on mathematical models. This calls for a scientific tool to support regional road safety management. The article uses the example of the region of Łódź to present the main road safety problems, analyse safety based on risk assessment, present the effects of selected factors on road user safety and forecast fatalities for different scenarios of treatments.

The article presents the results of research regarding the impact of technical and technological innovations on the quality of services in road transport of goods. The study was conducted using a structured questionnaire survey on a sample of134 road transport companies. Respondents were managers and business owners. 7 factors, which potentially determined the quality of services, were assessed by the respondents. The data analysis used the arithmetic mean and the dominant, which formed the basis for determining the importance of a given factor for the quality of services. The variability analysis provided information about the variation of the sample. The results of the research proved the influence of innovation on quality. The highest-ranked factors supporting the quality ofroad transport services were intelligent transport systems, the ability to minform the customer about the actual location of the shipment (delivery time) and systems supporting the work of a professional driver. The article also identified selected innovations and attempts were made to determine their importance in the development of the quality of services and the effects of their functioning on the road transport system.

Framework Conditions

About 36% of fatal road accidents in Norway involve at least one driver who is “at work”. It has been argued that the implementation of rules clearly defining the responsibility of road transport companies to prevent work related accidents, by implementing safety management systems (SMS), could lead to increased safety. In the present study we tested the validity of this suggestion, by examining the influence of different sector rules on work-related accident prevention in Norwegian road and maritime transport. In contrast to the road sector, the maritime sector has had rules requiring SMS for over 20 years, clearly defining the shipping companies responsibility for prevention of work-related accidents. The aims of the study were to: (1) examine how the different sector rules influence perceptions of whether the responsibility to prevent work-related accidents is clearly defined in each sector; and (2) compare respondents’ perceptions of the quality of their sectors’ efforts to prevent work-related accidents, and factors influencing this. The study was based on a small-scale survey (N = 112) and qualitative interviews with sector experts (N = 17) from companies, authorities, and NGOs in the road and the maritime sectors. Results indicate that respondents in the maritime sector perceive the responsibility to prevent work-related accidents as far more clearly defined, and they rate their sector’s efforts to prevent accidents as higher than respondents in road. Multivariate analyses indicate that this is related to the scope of safety regulations in the sectors studied, controlled for several important framework conditions. Based on the results, we conclude that the implementation of SMS rules focused on transport companies’ responsibility to prevent work-related accidents could improve safety in the road sector. However, due to barriers to SMS implementation in the road sector, we suggest starting with a simplified version of SMS.

The work, based on previously little available for research, as well as materials and documents found in archival institutions, reflects the legal basis for ensuring road safety in 1948-1953, the state and organizational and legal measures taken in the field of combating accidents in road transport at the republican level by the example Ukrainian Soviet Socialist Republic. Attention is focused on the key problems that determine the development of the road safety system, the measures taken, their effectiveness, mistakes and achievements. Measures to counteract accidents in vehicles are investigated from a historical and legal standpoint, a critical and detailed analysis of decrees and orders of the government, departmental regulatory legal acts. It was found that the presence of a significant number of administrative decisions of the republican authorities of Soviet Ukraine, although it was a rather progressive step for its time, did not fully take into account the reality of achieving the set goals, local conditions and peculiarities. At the same time, the functioning of the emerging road safety system was significantly hampered by the lack of a unified national policy in the context of the rapid growth and development of the country’s automobile and road complex.
