Car drivers' road safety performance: A benchmark across 32 countries

The road safety performance of a country and the success of policy measures can be measured and monitored in different ways. In addition to the traditional road safety indicators based on the number of fatalities or injured people in road traffic crashes, complementary road safety performance indicators can be used in relation to vehicles, infrastructure, or road users' behaviour. The last-mentioned can be based on data from roadside surveys or from questionnaire surveys. However, results of such surveys are seldom comparable across countries due to differences in aims, scope, or methodology.This paper is based on the second edition of the E-Survey of Road Users' Attitudes (ESRA), an online survey carried out in 2018, and includes data from more than 35,000 road users across 32 countries. The objective is to present the main results of the ESRA survey regarding the four most important risky driving behaviours in traffic: driving under the influence (alcohol/drugs), speeding, mobile phone use while driving, and fatigued driving. The paper explores several aspects related to these behaviours as car driver, such as the self-declared behaviours, acceptability and risk perception, support for policy measures, and opinions on traffic rules and penalties.Results show that despite the high perception of risk and low acceptability of all the risky driving behaviours analysed, there is still a high percentage of car drivers who engage in risky behaviours in traffic in all the regions analysed. Speeding and the use of a mobile phone while driving were the most frequent self-declared behaviours. On the other hand, driving under the influence of alcohol or drugs was the least declared behaviour. Most respondents support policy measures to restrict risky behaviour in traffic and believe that traffic rules are not being checked regularly enough, and should be stricter.The ESRA survey proved to be a valuable source of information to understand the causes underlying road traffic crashes. It offers a unique database and provides policy makers and researchers with valuable insights into public perception of road safety.     

International and intercultural differences in arguments used against road safety policy measures

Policy measures in the field of road safety are not easily implemented for several reasons. Interventions can be undertaken in a multitude of policy areas, but it is often uncertain how effective the measures are. Moreover, policymakers may be reluctant to implement road safety policy measures because of the expected high costs and/or perceived low public support. To understand the arguments used against policy measures for road safety, a survey was conducted in ten countries (China, the United States, the United Kingdom, Belgium, Austria, Sweden, Greece, France, Nigeria, and Argentina). Respondents were presented with ten possible road safety measures and asked whether they would support or oppose them, what arguments their opinion was based on, and what the consequence of the measure would be on them individually. This paper describes the main findings of the research and then zooms in on three counterarguments: restriction of mobility, discrimination, and unjustifiability of state interventions, as well as on three of the measures considered—compulsory use of ISA systems, mandatory cycle helmets, and screening of older motorists. With this research, previous results on the level of public support have been confirmed, and new insights have been gained. If people feel safe when using a particular transport mode, they are less conscious of the need for additional or stricter measures affecting their transport mode. The perceived restriction of human liberties, fear of discrimination, and resistance to state interventions fuel opposition against measures. Moreover, people from different countries vary in what they consider fair and unfair, which is linked to the national culture and social organization. Even if a measure was perceived to be unfair from a certain perspective (e.g., discrimination), some respondents supported the measure. Our research also illustrates that even people who recognize that a measure would be effective might oppose it because they think it is not justified from at least one perspective, for instance, an excessive restriction of freedom.     

Effectiveness evaluation on cross-sector collaborative education programs for traffic safety toward sustainable motorcycle culture in Vietnam

Motorcycle injuries have caused serious implications for public health and national economies in many ASEAN countries. Drivers' lack of road safety awareness and low level of voluntary compliance hinder the promotion of traffic safety. Against this background, the Vietnamese government cooperated with motorcycle manufacturers in a wide range of educational activities. This study evaluates the effectiveness of cross-sector collaborative education programs implemented in Vietnam through a series of statistical analyses. Utilizing a sample of 600 respondents, we focus on the educational effects on riders' attitudes, behaviors, accident prevention, and riders' psychological changes after participating in safety activities. The results show that the effectiveness of rider training differed depending on riders' experience. Motorcyclists' improvement in risk awareness mainly results from the enhancement of safety awareness. The structural model revealed that safety activities have positive effects on motorcyclists' riding confidence, safety awareness, joy and comfort while riding, independence and freedom in daily life, and perspective-taking abilities. Altruistic motivation is suggested as the key factor to encourage motorcyclists' safe riding, highlighting the importance of building up traffic moral and expanding traffic safety culture across the country. With an attempt to find out the insufficient and missing content from the present training programs, this study seeks to inform policy decisions on accident prevention as well as promote motorcyclists' well-being based on the sustainable motorcycle culture in ASEAN countries.     

Meeting the management challenges of the Decade of Action for Road Safety

In low- and middle-income countries, the high price paid for mobility in terms of human loss and suffering is forecast to rise to unprecedented levels. More than 50 million deaths and 500 million serious injuries on the world's roads can be projected with some certainty over the first 50 years of the 21st century, unless sustained new initiatives are taken. This paper addresses the emergence of road safety as a development priority over the last decade and the management challenges facing the planned global response aimed at bringing road safety outcomes in developing countries under control. It outlines the decade of advocacy that created the UN Decade of Action for Road Safety 2011–2020 and related Global Plan, and highlights the concern that over the coming decade low and middle income countries will face considerable management challenges in successfully implementing related measures and sustaining their delivery. The paper discusses new road safety management tools that have been developed by the World Bank and ISO to provide assistance to countries and organizations within an integrated framework that ensures that measures taken are properly sequenced and adjusted to their absorptive and learning capacities. It concludes that strengthened institutions and the accelerated knowledge creation and transfer central to this, plus scaled-up investment and increased international cooperation and development aid are critical to the successful achievement of the Global Plan's ambitious goal.     

Vulnerable road users: Cross-cultural perspectives on performance and attitudes

Pedestrians, cyclists and powered two-wheeler riders are considered vulnerable road users, as they are prone to a high risk of injury in the event of vehicular collision. This paper sought to elucidate the road safety performance and attitudes of vulnerable road users in 32 countries. In addition, comparisons between countries and demographic characteristics have been conducted, and recommendations that could enhance vulnerable road users' safety have been provided. For the study, data from the second edition of the ESRA survey (E-Survey on Road Users' Attitudes – ESRA2) conducted in 2018 were utilized. The results indicate that crossing the road at places other than nearby pedestrian crossings, reading a text message or checking social media while walking on the streets, cycling and riding without wearing a helmet, and speeding on powered two-wheelers outside built-up areas but not on motorways/freeways were the most frequently reported self-declared behaviours in the 32 countries. Finally, some solutions on preventing road crashes and increasing vulnerable road users' safety such as infrastructure interventions, use of protective equipment, and training and educational campaigns are discussed.     

An international comparative study on driving attitudes and behaviors based on questionnaire surveys

Road traffic crashes (RTCs) are influenced by a driver's awareness and attitude toward road safety, as well as the socio-economic status, infrastructure development level, traffic status, social system, and traffic safety culture of the area to which the driver belongs. In this study, based on the results of a questionnaire survey conducted in seven countries, the characteristics of each country concerning tolerance for traffic violations, dangerous driving, and acceptance for road safety measures were studied. It was suggested that a high tolerance for traffic violations and dangerous driving might affect traffic violations and RTCs in each country. Additionally, to reduce the tolerance for traffic violations and dangerous driving, the promotion of road safety education, especially among young and male drivers, and stricter regulations and enforcement were suggested.     

Study on influence of walking experience on traffic safety attitudes and values among foreign residents in Japan

The most vulnerable user in road space is still an ordinary pedestrian even though the top fatalities by traffic mode differ in countries. Thus, prioritizing/protecting vulnerable road users is essential to improve road safety. People's safety perceptions toward vulnerable users are strongly associated with surrounding elements and their own experiences, especially as pedestrians. Therefore the attitude and values toward vulnerable users would vary due to culture and customs related to walking in each country. This study examines how a walking experience change reflects people with diverse backgrounds' traffic safety attitudes by conducting an online questionnaire survey for foreigners living in Japan for five years or less. As a result, 75% of respondents walk more frequently due to increased public transportation usage. For all the respondents, the increase in the walking frequency also drives the shift in the attitude toward vulnerable users and the values regarding travel safety and comfort indirectly intermediated by the shift in attitudes toward walkability, applying structural equation modeling. To focus on the structure of the shift according to nationality, people from Southeast/South Asia, where motorcyclists are the top fatalities in the road space and somehow regarded as vulnerable road users, the increased walking experience contributes significantly to the improvement of awareness of vulnerable road users and to the formation of safety and comfort values. Regarding people from Europe/North America, although their walking frequency increases after coming to Japan, there is a static causal relationship that does not influence their attitude toward walkability or safety and comfort values. Additionally, they already have an attitude of protecting/prioritizing pedestrians and placing more importance on safety and comfort. At the same time, people from Southeast/South lacks the attitude toward pedestrians due to much less frequency of walking in daily life. It suggests that establishing safe and having comfortable pedestrian spaces and public transport in developing countries where traffic infrastructure is at the development stage will encourage people to walk and likely help foster an attitude of placing importance on safety.     

Education influence in traffic safety: A case study in Vietnam

It is well known that traffic accidents are of high importance to the public health spectrum around the world. Moreover, in developing countries such as Vietnam, the mortality rate from road traffic accidents is rather high in comparison with other Southeast Asian countries. Not only do the majority of the people killed and seriously injured significantly affect the quality of life of the citizens, but traffic accidents also negatively impact a nation's economic and social development. Statistics show that far more people are injured or die in traffic accidents than are afflicted by any of the most serious diseases. The very high occurrence of traffic accidents in Vietnam has become one of the country's major social issues. The importance of human factors in transport policy discussion is growing. There is a realization that policy options that appear beneficial in principle have to be checked for their feasibility of implementation. Understanding and describing driver behavior become a challenge when one tries to identify driver errors in determining accident/conflict causal factors and countermeasures.In recent years, having understood the serious effects of traffic accidents on society at large, scientific researchers, traffic engineers and policy makers in Vietnam have developed many projects and conducted research in the field of traffic safety. The human factor is also considered to be the central element in the whole system. The final goal is to organize a traffic environment that is convenient and safe for road users.This article explains the application of the risk analysis approach in evaluating influences of education and enforcement in traffic safety.

Socio-cognitive factors in road safety monitoring – Cross-national comparison of driving under the influence of alcohol,drugs or medication

The objective of the study is to assess the relation between socio-cognitive factors and unsafe traffic behaviour in different national settings. The study is based on the results of the second edition of ESRA (E-Survey of Road users' Attitudes), which was conducted in 32 countries in 2018 (ESRA2). The investigation focuses on the topic driving under the influence of alcohol, drugs, or medication (DUI) and related socio-cognitive constructs, i.e., attitudes, norms, perceived behaviour control, intention, and habits, and risk perception. Cross-national differences are assessed upon the example of Australia, Belgium, Canada, Egypt, Japan, Nigeria, and Slovenia. In the analysis, principal component analysis (PCA) was used to test the dimensions of the underlying socio-cognitive constructs and to define composite scores for further analysis. Linear regression models were fitted to investigate the association between these socio-cognitive factors and self-reported DUI. The same set of variables was used for all the linear regression models, i.e., the cross-national model (32 countries), and the seven national models. In total, 25,459 car drivers (at least a few days a month), were included in this analysis. The results show that: (i) the considered socio-cognitive factors are able to predict self-reported DUI across the different countries; (ii) these socio-cognitive factors are also able to predict DUI on a national level; (iii) the impact of socio-cognitive factors on DUI differs across countries. The strongest predictor in all countries was the construct habits, followed by norms and, to a lesser extent, attitudes and intention. Perceived behaviour control and risk perception only showed a significant effect on reported DUI in a few countries. In conclusion, the ESRA2 data offer a unique opportunity to gain valuable insights into cross-national differences in traffic safety. Future research will focus on a more in- depth analysis of cross-national differences to other road safety topics.     

Safe System in road safety public policy: A case study from Victoria,Australia

Safe System has been the dominant approach to road safety in Victoria for over fifteen years, guiding the development and implementation of policy. Limited attention has been paid to the development and application of Safe System in a public policy setting. The aims of this research were to describe the intentions of Safe System in Victoria, and analyse how well this aligns with models of successful public policy. Using a qualitative approach, semi-structured interviews were undertaken with Australian and international experts (n = 10). These experts represented a range of organisations and leadership levels that were either directly involved in the development or had a detailed understanding of the development of Safe System in Victoria. The interview results were analysed using a policy success model. The findings suggested that Safe System can provide a framework to address road safety in Victoria, however successful public policy needs to ensure that the development of policy addresses the identified problem and that the results are maintained for some time. Safe System meets some of these requirements, but principally lacks explanation for how its overarching approach is meant to be understood and utilised. Practically, road safety professionals need to clarify the purpose of the Safe System concept in order for it to be successfully integrated into public policy. Whilst Safe System requires additional clarification, it has garnered additional interest and debate in road safety and from this perspective has advanced public policy.     

Contribution of traffic behavior surveys for monitoring safety performance indicators in Germany: Case of mobile phone use while driving

Behavioral determinants in the form of safety performance indicators (SPIs) are increasingly being applied in addition to road traffic crash statistics to evaluate road safety. These SPIs help understand driving behaviors and adopt preventive measures for crashes. Behavior-explaining determinants, including attitude or subjective norms, are defined in the theory of planned behavior and are collected through surveys. In this study, data from three traffic behavior surveys, conducted in Germany, were employed, taking the example of mobile phone use while driving, which causes distraction and represents a road safety risk. The surveys differ in their methodology and results. While the Traffic Climate in Germany has been surveying the determinants of mobile phone use in a representative sample for several years, the E-Survey of Road Users' Attitudes (ESRA) is conducted in parallel in several countries and allows for comparison with Germany. The survey by the International Association of Traffic and Safety Science (IATSS) only included the group of young drivers in Germany. All three surveys demonstrate that although attitudes and subjective norms tend to be negative, mobile phones are nevertheless used while driving. Major differences exist depending on the mode of use (hands-free calling, texting) and recent developments. Thus, regularly surveying the determinants and mapping the latest developments in terms of content is critical. Together, these surveys provide comprehensive insights into the topic and enable prevention approaches, such as the concrete communication of information to young drivers and the emphasis on dangers, even during the hands-free use of mobile phones while driving.

The future of road safety: A worldwide perspective

Estimates by the World Health Organization suggest that, on a yearly basis, road crashes kill 1.25 million people—nearly 3400 road fatalities per day—and injure up to 50 million. Traffic injuries are not equally spread over the world, however; some countries are hit harder than others, and the chance of being killed in a road crash depends on where one lives. Almost 90% of all traffic casualties occur in low- and middle-income countries (LMIC). Globally, the number of fatalities per 100,000 population (mortality rate) ranges from less than 3 to almost 40. The rate is less than 9 in high-income countries (HIC) but averages around 20 in LMIC, with the African region demonstrating the highest rate (26.6). While road safety trends have been positive in HIC over the last few decades, trends in LMIC are not telling a positive story: road fatalities are expected to increase to almost 2 million road fatalities per year by 2020.The United Nations has adopted several resolutions on road safety and proposes actions to tackle the global road safety crisis. Considering the current level of road safety to be unacceptable, the UN has taken several initiatives. One effort, the Decade of Action for Road Safety 2011–2020, has generated substantial activity around the world over the last couple of years. Furthermore, it is very encouraging that the UN included road safety in the Sustainable Development Goals that it laid out in September 2015. Road safety is part of the public health agenda and the urban development agenda. Measured in “real actions,” however, the responses so far from the overall global community and individual countries do not suggest that we are already on the right track to bringing down the death toll on roads.The future of road safety is uncertain and definitely not the same for all regions of the world. Countries with a mature road safety approach and an ambition to make further progress are expected to move in the direction of a pro-active approach: a Safe System approach. It is reported that many LMIC, meanwhile, are on the brink of designing road safety strategies and implementing action plans. The international community is willing to support LMIC, but LMIC cannot simply copy successful HIC strategies because local circumstances differ. The principles of successful HIC strategies are applicable, but the priorities and action plans should take root in and align with local conditions.     

The impact of road improvements on road safety and related characteristics

This paper presents the historical and cultural background relating to road improvement and road safety characteristics in Kenya, a developing country in East Africa. Some who come from low-developed areas of developing countries often take time to comprehend the modern transportation infrastructure, especially roads, and have difficulty assimilating and customizing the same to their culturally tailored modes.This paper discusses two case studies: one on the socio-economic impact following improvements to a 50-km, high-class, high-traffic-volume road and the other on the monitoring and evaluation of road safety aspects along the Northern Corridor in Kenya also following major road improvements.The road improvements to the Nairobi-Thika Highway (a trunk road) have attracted many investors along the highway corridor. The high-speed road has also brought with it the unfortunate consequence of speeding vehicles colliding with pedestrians crossing the road at undesignated locations.The Northern Corridor, the transportation corridor that links the Great Lakes Countries of the Democratic Republic of Congo, Burundi, Rwanda, and Uganda from the port of Mombasa in Kenya, has had high accident rates for a considerable amount of time. The results of monitoring and evaluation exercises on the Northern Corridor have shown that drivers are the major contributors in causing accidents, with a component ratio of 49.4%; pedestrians are next at 21.7%. Data also shows that 24% of the accidents along the Northern Corridor are fatal, which is of major concern. The study additionally indicated that the majority of road users have not been exposed to education or training on road safety.This paper presents a number of recommendations arising from the road safety study regarding possible improvements in aspects of road safety along the corridor and potential applications of those changes to other roads in general. For example, there are recommendations related to the geometric design of the road, driver training and behavior, vehicle maintenance, and the need to enhance road safety through the utilization of road safety parks where road users can undergo training and drills on road safety aspects.In conclusion, we argue that the rehabilitation of the Northern Corridor from Mombasa on the Kenyan coast to the border with Uganda has led to significant road safety improvement.     

Exclusive motorcycle lanes: A systematic review

Road accidents are the main leading cause of death, and more than half of people killed in road accidents are motorcyclists, pedestrians, and bicyclists. In developing countries, the share of motorcycles is very high in the traffic stream, which results in an increased number of accidents. Nonetheless, a high share of motorcycles and risky riding behavior of motorcyclists raise notable threats to other road users as well as themselves. Segregating motorcycles from the main traffic stream by providing an Exclusive MotorCycle Lane (EMCL) is reported as one of the strategies to improve motorcyclist's safety and overall road safety. Although EMCLs are successfully running in some Asian countries like Malaysia, Taiwan, and Indonesia, and have reported reducing motorcycle accidents, existing literature related to such lanes is limited and lacks combined contemplation of various design factors. Therefore, a systematic review of studies related to EMCL was carried out in the present paper using the PRISMA approach. The review was majorly divided into the following three categories viz., geometric design elements of EMCL, motorcyclist's flow characteristics on EMCL, and traffic control measures for EMCL to highlight the research lacunas in this field. The present study aims to cast light on the need for specific geometric design standards for EMCL and to assess the safety impact of segregating motorcyclists from other mixed traffic. The review highlights that the design standards for EMCL should be based on the motorcycle's characteristics, as it varies from other vehicle categories in terms of riding behavior and the physical properties of the motorcycle.     

Traffic problems in Southeast Asia featuring the case of Cambodia's traffic accidents involving motorcycles

This article provides the background to the special issue by reviewing the status of traffic problems in South East Asian countries, and in particular, the case of Cambodia. The “Make Roads Safe” report by the Commission for Global Road Safety (2011) confirms traffic accidents as the primary cause of youth mortality worldwide. Thus, the United Nations declared the decade from 2011 to 2020 as the “UN Decade of Action for Road Safety 2011-2020”, promoting road safety and to reduce the number of deaths in road accidents by 2020. Furthermore, the “Sustainable Development Goals” adopted in 2015 highlight the important role of sustainable transport in tackling the exclusion of vulnerable groups. On the other hand, the World Health Organization in 2015 indicate an increase in the death rate due to traffic accidents in low-income countries since 2000. Traffic accidents were already recognized as a social problem before the 2000s in countries such as Thailand and the Philippines. At the same time, other ASEAN member states such as Vietnam and Cambodia which have experienced rapid economic growth since the 2000s are now experiencing the seriousness of traffic problems. It is said that 70% of road accidents in Thailand, Cambodia and Laos involve motorcycles and three-wheelers, but despite this situation, the regulatory framework for motorcycles remains undeveloped. In the case of Cambodia, speeding by young people remains the major cause of road deaths and this can be explained by the fact that people can now travel at a higher speed because of road developments but remaining challenges related to underdeveloped traffic legislation, and limited public awareness and knowledge of road safety are overlooked. In 2010, the Cambodian National Road Safety Action Plan 2010–2020 was drafted, aiming to halve the number of deaths in traffic accidents in 2020. However, in reality, the number of road deaths did not decrease to the level anticipated in the action plan until 2016. In this article, the authors emphasize the importance of implementing the “three Es” namely Engineering, Enforcement and Education in developing countries such as Cambodia. In particular, the authors claim that the role of education to increase people's road safety awareness is neglected compared to the other two dimensions and thus, it is highly important to raise people's road safety awareness through education among the young people.     

International analysis on social and personal determinants of traffic violations and accidents employing logistic regression with elastic net regularization

While the number of road fatalities is declining in developed countries, it is still increasing globally, especially in middle-and low-income countries. In addition to the driver's individual awareness and attitude toward traffic safety, various factors such as the development of road infrastructure and the legal system may have a significant influence on the occurrence of traffic accidents. Thus, it is essential to consider these factors to enhance traffic safety and achieve Sustainable Development Goal (SDG) Targets of 3.6.In this study, we developed an Elastic Net Regression model to evaluate the factors that influence an individual's traffic violations and accidents based on an international questionnaire on traffic safety attitude, country fact survey data on traffic regulations, and other statistical databases. As a result, it was revealed that: i) In addition to country-level factors, the individual's attributes and attitudes toward traffic safety have an influence on the experience of traffic violations and accidents. and ii) While the same variables regarding individual attributes and attitudes are selected for both traffic violations and accidents, the selected variables relating to country factors differ between violations and accidents.     

A conceptual framework for road traffic safety considering differences in traffic culture through international comparison

Many countries and international organizations have put a significant amount of effort into improving road traffic safety by setting their own road traffic safety goals and strategies. This study aims to provide a conceptual framework for road traffic safety through an international comparison of traffic safety goals and strategies. Such a comparison can help improve mutual understanding and communication among stakeholders in different countries and international organizations. Based on a review of previous traffic safety literature and comparing traffic safety strategies of several different countries and international organizations, this study proposes a conceptual framework for road traffic safety consisting of a common vision, traffic safety indicators, a safe system including the 3Es and some additional Es, and a traffic safety culture, which is the basis of the framework.     

What affects pedestrian crossing difficulty at urban intersections in a developing country?

In developing countries, road traffic crashes involving pedestrians have become a foremost concern. At present, road safety assessment plans and selection of interventions are primarily restricted to traditional approaches that depend on the investigations of historical crash data. However, in developing countries such as India, the availability, consistency, and accuracy of crash data are major concerns. In contrast, proactive approaches such as studying road users' risk perception have emerged as a substitute method of examining potential risk factors. An individual's risk perception offers vital information on probable crash risk, which may be beneficial in detecting high-risk locations and major causes of crashes. Since the pedestrian fatality risk is not uniform across the urban road network level, it may be expected that pedestrians' perceived risk measured in terms of “crossing difficulty” would also vary across the sites. In this perspective, the present paper establishes a mathematical association between the pedestrians' perceived “crossing difficulty” and actual crashes. The model outcome confirms that pedestrians' perceived crossing difficulty is a good surrogate of fatal pedestrian crashes at the intersection level in Kolkata City, India. Subsequently, to examine the impact of traffic exposures, road infrastructure, land use, spatial factors, and pedestrian-level attributes on pedestrians' “crossing difficulty”; a set of Ordered Logit models are developed. The model outcomes show that high vehicle and pedestrian volume, vehicular speed, absence of designated bus stop, the presence of inaccessible pedestrian crosswalk, on-street parking, lack of signalized control (for both vehicle and pedestrian), inadequate sight distance, land use pattern, slum population, pedestrian-vehicular post encroachment time, waiting time before crossing, road width, and absence of police enforcement at an intersection significantly and positively increase pedestrian's crossing difficulty at urban intersections. To end, the model findings are advantageously utilized to develop a set of countermeasures across 3E's of road safety.
