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.

Abstract Road inspection regularity and existing types made by road maintenance crew have not been good enough to be aware what is really happening on the roads. Road users' contribution in road traffic safety is very important to ensure fast reaction on different road hazards. It is important to ensure not only the most common ways to report road hazards on state roads by phone, by email and on social media, but also expand data sources options in modern and user-friendly way. Waze navigation application already had functionality to report road hazards – to warn other application users, but no one acted to solve these road hazards until someone reported them through existing communication channels supported by Latvian State roads or Latvian road maintainer. To ensure better road traffic safety and faster reaction time on road hazards solving, Latvian road maintainer gained access to Waze report feed, and, in corporation with Riga Technical university, made a system for analysing and processing Waze data. As the result - Latvian roads maintainer can improve road safety by faster reaction to road hazards reported by Waze users. Today, up to 70 % from total reports processed by Latvian road maintainer are generated by Waze.

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 Telematics

Transport telematics systems integrate information technology with telecommunications for the purposes of transport systems. This helps to improve the safety of vehicles and facilities involved in transport tasks. At the same time, the efficiency of using transport infrastructure and means of transport increases. The development and use of specialised IT applications that use data from transport telematics systems helped to create Intelligent Transport Systems (ITS). Currently, in Poland (in Europe and in the world), more and more advanced services offered by Intelligent Transport Systems are being developed and implemented. It is particularly relevant in road transport, especially because Poland’s road safety is insufficient compared to other European countries. The article presents the authors’ proposed indicators and criteria that can be used for assessing ITS services in the context of road safety. The authors conducted analyses to study the application of AHP (Analytic Hierarchy Process), if ITS services were to be used to improve road safety. Then, it will be possible to choose one solution from all the assessed ones.

Background: Globally, road traffic injuries are estimated to be the leading cause of death among young people aged 15–29 years, and second leading cause of death in 10–14 years and 20–24 years age groups. The objective of the study is to assess the knowledge, attitude and practice towards road traffic safety among adolescent students of a selected Pre-University college in Raichur city.Methods: Cross-sectional study conducted among (372) adolescent students of a selected Pre-University college in Raichur city by using pre-tested, semi-structured questionnaire and analyzed using Epi-Info software. Chi-Square test was applied and level of significance was kept at P value of <0.05.Results: Mean age of the participants was 16.68±0.75. 196 participants (52.8%) had adequate knowledge on the road safety rules and regulations. Only 25 participants (7.7%) were driving with a valid driving license. The most common reason for motor vehicle accidents was high speed. Knowledge adequacy about road safety rules and regulations had statistically significant association with age and gender.Conclusions: Mere knowledge does not necessarily translate into improved traffic behavior as was seen in this study. School/college is the basic institution where we can formulate interventions. Continuous reinforcement and education reminding them of traffic rules can bring about a positive change and motivate them to strictly adhere to the traffic norms and help reduce the morbidity and mortality regarding road traffic accidents.

The number and severity of road accidents in Vietnam is at alarming rate. From 2003, the Government has tried to improve traffic safety, therefore the number of accident and traumatic brain injury (TBI) and the rate of death reduced suddenly. However, from the end of 2008, even though accident number decreasing, a number of TBI and deaths due to road crash are jumping up. This paper aims to analyze the reason of heavy injuries, TBI and deaths happening increased. The specific surveys were taken to motorcyclists, helmet market, traffic safety agencies and hospital in Hanoi and Ho Chi Minh City. Statistic method, integrated comparison, observation, expert interview survey and brainstorming method have been used in this study to analyze the problem. Then road safety situation, helmet usage, regulation and enforcement were analyzed. Base on these, proposal to improve road safety in the two major cities in Vietnam is going to be discussed.

Road Traffic Safety

BackgroundMedia coverage of road traffic collisions (RTCs) may influence preventative action. India experiences some of the highest RTC mortality and morbidity rates globally, but advocacy and effective action to mitigate this has been limited. We conducted an analysis of Indian media in English to assess whether coverage met the WHO’s Reporting on Road Safety guidelines for evidence-based reporting of RTCs.MethodsEnglish-language articles published online between March 2018 and February 2019 were assessed against the seven recommended story angles and seven recommended key elements in the WHO guidelines.Results458 articles were included in the analysis. The most common story angle was descriptions of single collisions, which was not a WHO-recommended story angle. These included limited key elements such as use of human story or linking to road safety risks or evidence-based solutions. However, some articles did follow the WHO-recommended story angles, with 22.1% discussing specific road safety solutions and a further 6.3% discussing vulnerable groups. Almost all articles avoided the use of technical language, but only 2.0% explicitly stated that RTCs were preventable. More than half identified at least one evidence-based solution. Very few articles discussed economic or health impacts of RTCs, including the burden they present to the public health system.ConclusionIndian media in English can improve reporting by focusing on human stories and documenting experiences of those injured in RTCs. Coverage should also focus more on evidence-based solutions, emphasising the systems approach which encourages government action rather than changes to individual behaviour.
