The objective of road infrastructure safety management is to ensure that when roads are planned, designed, built and used traffic accident risks can be identified, assessed and mitigated. There is a number of approaches, methods and tools for road safety infrastructure management. European Union Directive 2008/96/EC regulates and proposes a list of tools for managing road infrastructure safety. The paper presents two of these tools - classification of dangerous sections and control of the infrastructure in the field of safety. The final section presents the necessary directions for further action, particularly scientific research, supporting the management of the existing road infrastructure.

The analysis of national data on the number of deaths showed that in Poland from 2010 to 2016 it was possible to reduce the number of fatalities by about 22%. The tendency of changes in the number of fatalities, however, is not homogeneous. When data of individual voivodships is analyzed, the situation is different. The largest reduction in fatalities in the analyzed period of time concerned voivodship Świętokrzyskie, where there was more than 45% drop in the number of fatalities. The following voivodships: Łódzkie, Lubelskie and Podkarpackie recorded a decrease in over 30% of fatalities. Unfortunately, at the end of the classification there were four voivodships with a fall below 8%, and what is disturbing voivodship Lubuskie recorded a nearly 5% increase in the number of fatalities. The current traffic safety management at the level of voivodships is often the implementation of central recommendations, which, as results from the analysis of statistical data, are not equally effective in every province. Therefore, models for forecasting changes in road safety are required. Taking into account local characteristics and implemented actions can be used to manage security more effectively at the regional level. This paper presents examples of the use of mathematical models to predict the number of fatalities in individual voivodships depending on the adopted action scenarios. Regression models were developed, taking into account demographic, infrastructural, economic and automotive factors. It turned out that in individual voivodships, various factors affect the level of road safety on roads differently. Therefore, an individual approach to each voivodship is important in order to reliably forecast the level of security.

Road safety is the crisis condition in developing countries such as Indonesia. Based on 2016 data, the dead tolls of road accidents were 26,000, or 10.9 fatalities per 100,000 inhabitants. The majority of victims was between 15 and 29 years old (IRSMS, 2016). This condition shows the human capital lost caused by many dead prematurely on road. The Long Term National Road Safety Plan (RUNK) declareted in 2011 has the main goal is reducing road fatalities by 50% and 80% in 2020 and 2035 respectively. Indonesia National Police (INP) has the main role to coordinate and realize safer road users in the RUNK. Integrated Road Safety Management System (IRSMS) is the road accident data- based application that was developed by INP and it must be the evidence based for decision policies and development action plan activities. Establishment of Traffic Accident Research Centre (TARC) has the main objective to sinergising Indonesia traffic police with academia and researcher to carry out in depth study as well as to develop programmes that able both structural and cultural to construct safety concern society. INP understands that enforcement program solely cannot solve road safety problem. It recognizes that achievement is not possible without understanding the problems and incorporation with all stakeholders in road safety. Keselamatan di jalan raya adalah sesuatu hal yang kritis di negara berkembang seperti Indonesia. Data kecelakaan pada tahun 2016 menunjukan 26.000 orang, 41.9 orang per 100.000 penduduk meninggal di jalan raya dimana mayoritas korban berusian 15 – 29 (IRSMS, 2016). Kondisi memperlihatkan kehilangan negara atas aset sumber daya yang dimiliki. Rencana Umum Nasional Keselamatan (RUNK) pada tahun 2011bertujuan menurunkan fatalitas di jalan raya. POLRI mempunyai peran utama dalam mengkoordinasi dan menciptakan pengguna jalan yang berkeselamatan. Integrated Road Safety Management System (IRSMS) adalah aplikasi pencatatan data kecelakaan yang dikembangkan oleh POLRI harus dijadikan basis pengambilan keputusan dan aktifitas kampanye keselamatan di jalan raya. Pendirian Traffic Accident Research Centre (TARC) bertujuan menciptakan sinergitas antara KORLANTAS POLRI dan akademisi dalam melakukan in-depth study serta. Penciptaan program yang mampu secara struktur dan kultur menciptakan masyarakat yang berperilaku pengutamaan terhadap keselamat karena melakukan tindakan represif semata-mata tidak dapat menyelesaikan masalah keselamatan jalan.

Road Tunnels

Tunnels are underground passages, placed horizontally, which serve to lead the road through them. In order to fulfill its purpose in road traffic, the tunnel must fit into the traffic infrastructure and as such not create an obstacle in movement and enable the movement of vehicles from entrance to exit without danger, but with increased restriction of freedom of lateral evacuation. Tunnels are among some of the most risky parts of the road network, primarily due to space constraints, where there is a possibility of a traffic accident. Managing the risks associated with the passage of road traffic, and in particular the safety of traffic in tunnels, is a serious problem in many countries. With the growing number of road users, it is necessary to adopt stricter standards regarding road tunnels. In addition to meeting these safety standards, factors such as operational requirements, economic efficiency, energy efficiency and state-of-the-art technology should also be taken into account when planning and equipping tunnels.

Network-wide road safety assessment throughout the whole network is one of the four road infrastructure safety management procedures regulated by Directive 2019/1936/EC of the European Parliament and of the Council of 23 October 2019 Аmending Directive 2008/96/EC on Road Infrastructure Safety Management and one of the methods for determining the direction of investment in road safety. So far, the implementation of the procedure has been lightly regulated and adapted using various road safety indicators. The paper describes the evaluation of road accident data that is one of the criteria for conducting a network-wide road safety assessment. Taking into consideration that networkwide road safety assessment is a proactive road safety activity, the paper proposes to conduct road safety assessment considering the expected fatal accident density. Such assessment makes it possible to assess the severity of accidents, and the use of the predicted road accident data on calculating the introduced road accident rate contributing to the prevention of accidents. The paper describes both the empirical Bayes method for predicting road accidents and the application of one of the road safety indicators – the expected fatal accident density – to determine five road safety categories across the road network. The paper demonstrates the application of the proposals submitted to Lithuanian highways using road accident and traffic data for the period 2014–2018.

Vulnerable Road Users

In the last ten years, there has been a stabilization of traffic fatalities on the roads of the world. At the same time, the death toll of persons in the armor of vehicles was reduced, and the death toll of persons outside the armor of vehicles-vulnerable road users continued to grow. The most endangered are motorcyclists, then pedestrians and finally cyclists, both in developed countries of the European Union and in underdeveloped and developing countries. Lagging behind in reducing the fatalities of vulnerable road users requires innovation in research and the creation and implementation of new road safety management policies. In this aspect, inclusive road infrastructure safety management in the settlement can be a paradigm for the introduction and implementation of protection of vulnerable road users, persons with reduced mobility and persons with disabilities, through procedures to control road safety in the settlement, at all stages of the road life cycle: planning, design, construction and exploitation. The content of inclusive road infrastructure safety management in the settlement should include all areas of activity and all elements of the roads of the settlement, the improvement of which can raise the level of traffic safety of all users, so that the roads of the settlement are equally safe for all road users. At the same time, the risk of fatal traffic accidents on the roads of the settlement is indirectly exponentially related to the scope of the content of inclusive road infrastructure safety management in the settlement.

On The Road

The European Directive on the Road Infrastructure Safety Improvement (2008/96/EC) has established the implementation of appropriate procedures as the basic tools for improving the road infrastructure on the trans-European road network. The Law on Roads (2018) prescribes the implementation of the following procedures: Road safety impact assessment; Road safety audit; Road safety inspection; Risk mapping; Black spot identification; and In depth road accident studies. The Law on Roads also prescribes that the Minister will prescribe the manner of implementation and the contents of the Evaluation, Audit and Independent Assessment reports, as well as the manner of determining the major risk portions and the identification and ranking of hazardous sites (black spots). Since the method of implementation and the content of the report are not yet prescribed, the authors contributed in this paper to defining the manner of implementation and content of the traffic safety report on the example of the section of the highway, as the highest category of state road. In the framework of the training of auditors and auditors, among others, a pilot project was carried out for the safety of traffic on the part of the E-75 (A1) highway, about 2,7 km ahead of the Mali Požarevac loop, including the loop. The verified part of the highway also includes a ramp with a toll ramp, service facility, overpass, bridge, etc., so the selected checked part is representative for defining a recommendation for the mode of implementation and the model for the preparation of the report.

The Impact

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.

The realizing and improvement of road infrastructure, of modern road networks provides normal, safe and pleasant road traffic conditions and also help prevent road accidents. The road network, with its constructive characteristics, has to offer optimal conditions for the movement of vehicles, pedestrians and other categories of participants in the road traffic. Starting from the case study of a road sector with heavy road traffic, the current paper analyzes the increase in road safety in Romanian localities along European and national roads through the implementation of specific measures such as setting up sidewalks, installing New Jersey median barriers, expanding the road sectors with 2+1 lanes, replacing normal pedestrian crossings with elevated crossings or with pedestrian crossing with mid-road waiting areas etc.

Abstract Key to understanding the needs and tools of road infrastructure management is identifying the hazards and their sources involved in having no or faulty road restraint systems. Clarity is also needed on why the systems are wrongly designed, constructed, built and operated. To ensure that the problem is adequately understood, research and site observations were conducted and mathematical models were built to describe the level of roadside risk. To aid studies of road safety barrier and other road safety equipment functionality, it is vital to carry out field crash tests and crash test simulations. The main goal of the work is to develop a method for selecting optimal road restraint systems.
