School Area Road Safety Assessment and Improvements (SARSAI) programme reduces road traffic injuries among children in Tanzania

Driver yield and safe child pedestrian crossing behavior promotion by a school traffic warden program at primary school crossings: A cluster-randomized trial

OBJECTIVE

To determine the effect of a school traffic warden program on increasing driver yield and safe child pedestrian crossing behavior in Kampala, Uganda.

METHODS

We designed and implemented a school traffic warden program in specific school zones in Kampala, Uganda. We randomly assigned 34 primary schools in Kampala, in a 1:1 ratio, using a computer-generated randomization sequence, to control or intervention arms in a cluster randomized trial. Each school in the intervention group received one trained adult traffic warden stationed at roads adjacent to schools to help young children safely cross. The control schools continued with the standard of care. We extracted and coded outcome data from video recordings on driver yield and child crossing behavior (defined as waiting at the curb, looking both ways for oncoming vehicles, not running while crossing, and avoiding illegal crossing between vehicles) at baseline and after 6 months. Using a mixed effect modified Poisson regression model, we estimated the prevalence ratio to assess whether being in a school traffic warden program was associated with increased driver yield and safe crossing behavior.

RESULTS

A higher proportion of drivers yielded to child pedestrians at crossings with a school traffic warden (aPR 7.2; 95% CI 4.42-11.82). Children were 70% more likely to demonstrate safe crossing behavior in the intervention clusters than in control clusters (aPR 1.7; 95% CI 1.04-2.85). A higher prevalence was recorded for walking while crossing (aPR 1.2; 95% CI 1.08-1.25) in the intervention clusters.

CONCLUSION

The school traffic warden program is associated with increased driver yield and safe child pedestrian crossing behavior, i.e., stopping at the curb, walking while crossing, and not crossing between vehicles. Therefore, the school traffic warden program could be promoted to supplement other road safety measures, such as pedestrian safety road infrastructure, legislation, and enforcement that specifically protects children in school zones.

Prevention of "bygone futures" due to road traffic injuries in children

Road traffic injuries remain one of the common and leading causes of death among children and adolescents till the age of 19 years. Road safety is important for children since their physical activity, active travel, independence and development are largely affected by it. Solutions for road safety with benefits for people as well as an economy exist which should be implemented effectively and efficiently. These solutions which combine engineering, legislation and behavioural interventions should be implemented in an integrated Safe Systems Approach. The future of the children must be safeguarded from these injuries and every effort towards it being converted into "bygone figures" must be done diligently and honestly. The various risk factors and interventions possibly explained in this review article shall help in better understanding of the causes and possible guidelines at a policy level to prevent road traffic injuries in children.

CBT program to reduce recidivism risk for road crashes among adolescents and young adults: Results of a randomized controlled study and prospects

Road crashes are the first cause of mortality for young adults aged 18-25 years and the human factor contributes to 90-95% of events. The present study was carried out to determine the efficacity of the ECARR2 recurrence prevention program among adolescents and young adults at high risk of having a new traffic crash in the following months. A total of 288 participants having had a traffic crash that required going to the emergency room, at high risk of accident recurrence (ECARR≥5) were randomly allocated to either the intervention group (n = 144) or the control group (n = 144).

Results

revealed that the risk of recurrence was highest during the first 6 months (66% of recurrences). In per-protocol analysis population, at 6 months after inclusion, the accident recurrence rate was 14.2% ± 3.3% in the intervention group, and 23.5% ± 4.0% in the control group. The intervention had an effect per se, independently of the other predictors (p = 0.020). This effect was mediated by the three interaction variables: BDI, Impulsive Behavior Scale lack of perseverance, and Orientation to Happiness engagement. It was therefore through these dimensions that the intervention had an effect. In conclusion, the ECARR score predicts the risk of recurrence, risk which is the highest during the first 6 months. Finally, results confirm the predictive validity of the ECARR scale. The ECARR score had an effect on the risk of recurrence regardless of group (p = 0.045) and was predictive of recurrence (p = 0.045).A brief psychological intervention such as ECARR2 program, offered to young people ar hight risk of having a new crash, just after the crash, seems to halve the risk of recurrence at 6 months. Future research should improve the brief psychological intervention and its access via a mobile application or few hours in high school or in a driving school given.

Road traffic injuries in Tanzanian children and adolescents: A cross-sectional household survey

OBJECTIVE

To measure annual rates of road traffic injuries (RTI) and to describe the characteristics of road traffic crashes experienced by children and adolescents in Tanga, Tanzania.

METHODS

We conducted a cross-sectional household survey using geospatial population-weighted sampling in the city of Tanga in northern Tanzania. Data were collected in February and March of 2022. We report 12-month rates of road traffic crashes and RTI (reported by adult caregivers) among children and adolescents <18 years of age.

RESULTS

A total of 2,794 adult respondents reported data on 6563 children and adolescents, among whom, 180 were reported to have experienced road traffic crashes in the past 12 months (crash incidence: 27.4 per 1,000 children, 95%CI 23.5-31.4) and 158 sustained injuries (RTI incidence: 24.1 per 1000 children, 95%CI 20.4-27.8). Almost a quarter of RTI (23%) were reported to be major (resulting in ≥30 days of missed activities). RTI was higher among adolescents (13-17 years) than children <5 years (21.5 vs. 14.1 per 1,000, p=0.039). Few children always or sometimes wore helmets when riding on motorcycles/motorbikes (12.8%) or wore safety restraints/seat belts in cars or other vehicles (11.9%).

CONCLUSION

The high rate of road traffic crashes and RTI observed among children and adolescents in a medium-sized city in Tanzania underscores the urgent need to improve road safety and increase use of safety equipment in low resource settings.

Interventions to prevent road traffic injuries among pedestrians: a systematic review

Road traffic injuries (RTIs) are a serious public health problem and are an important cause of disability and death worldwide. A significant proportion of traffic injuries and fatalities are among pedestrians. Reviewing and evaluating related interventions can be a practical step to implementing appropriate methods to prevent RTIs among pedestrians, a highly vulnerable group of road users.

The search of articles was conducted in the electronic databases of Scopus, PubMed, ISI, Safety Lit, and CDC. Other papers were also reviewed using forward citation and backward citation. The search strategy was for studies examined from the first years of database creation until January 10, 2021, in all languages in journals with matched judgment according to the type of population, type of interventions, comparators, and results. Joanna Briggs Institute (JBI) checklists were used to determine articles' quality and assess possible biases depending on the type of study.

The initial search resulted in finding 16,272 abstracts. Finally, 25 studies, including 17 randomized clinical trials (RCTs) studies, seven studies pretest/post-test interventions (PPI), and one study controlled pretest/post-test interventions (cPPI) met the inclusion criteria. Among these preventive interventional studies, 20 studies were conducted in high-income countries, three were in lower middle-income countries, one study was in upper middle-income country, and only one study was conducted in a low-income country. Most interventional studies in the field of prevention of RTIs (15 studies) had an educational/behavioral approach, designed to change pedestrian behavior and the use of this approach was also effective in improving pedestrian behavior. The legislation/law enforcement approach was used in one study and two studies used an engineering/technology approach. In studies with an engineering approach after engineering reforms, pedestrian injuries in children decreased by 37.5%. In seven studies, multifaceted interventions were used. The interventional studies that used this approach were able to improve pedestrian safe behavior.

The majority of studies were based on educational/behavioral approaches and pedestrians' behavior improved notably. In addition, the majority of interventional studies were conducted in countries with high income levels. Therefore, programming for preventive interventions to attenuate RTIs is highly important in low/middle-income countries to reduce the risk of injury to vulnerable road users. These findings can be applied by policy-makers to develop educational, engineering, environmental, and law enforcement interventions and attenuate injuries sustained by pedestrians.

Adolescent transport and unintentional injuries: a systematic analysis using the Global Burden of Disease Study 2019

Background

Globally, transport and unintentional injuries persist as leading preventable causes of mortality and morbidity for adolescents. We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10–24 years during the past three decades.

Methods

Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolute numbers and age-standardised rates per 100 000 population by sex, age group (10–14, 15–19, and 20–24 years), and sociodemographic index (SDI) with 95% uncertainty intervals (UIs). We report percentage changes in deaths and DALYs between 1990 and 2019.

Findings

In 2019, 369 061 deaths (of which 214 337 [58%] were transport related) and 31·1 million DALYs (of which 16·2 million [52%] were transport related) among adolescents aged 10–24 years were caused by transport and unintentional injuries combined. If compared with other causes, transport and unintentional injuries combined accounted for 25% of deaths and 14% of DALYs in 2019, and showed little improvement from 1990 when such injuries accounted for 26% of adolescent deaths and 17% of adolescent DALYs. Throughout adolescence, transport and unintentional injury fatality rates increased by age group. The unintentional injury burden was higher among males than females for all injury types, except for injuries related to fire, heat, and hot substances, or to adverse effects of medical treatment. From 1990 to 2019, global mortality rates declined by 34·4% (from 17·5 to 11·5 per 100 000) for transport injuries, and by 47·7% (from 15·9 to 8·3 per 100 000) for unintentional injuries. However, in low-SDI nations the absolute number of deaths increased (by 80·5% to 42 774 for transport injuries and by 39·4% to 31 961 for unintentional injuries). In the high-SDI quintile in 2010–19, the rate per 100 000 of transport injury DALYs was reduced by 16·7%, from 838 in 2010 to 699 in 2019. This was a substantially slower pace of reduction compared with the 48·5% reduction between 1990 and 2010, from 1626 per 100 000 in 1990 to 838 per 100 000 in 2010. Between 2010 and 2019, the rate of unintentional injury DALYs per 100 000 also remained largely unchanged in high-SDI countries (555 in 2010 vs 554 in 2019; 0·2% reduction). The number and rate of adolescent deaths and DALYs owing to environmental heat and cold exposure increased for the high-SDI quintile during 2010–19.

Interpretation

As other causes of mortality are addressed, inadequate progress in reducing transport and unintentional injury mortality as a proportion of adolescent deaths becomes apparent. The relative shift in the burden of injury from high-SDI countries to low and low–middle-SDI countries necessitates focused action, including global donor, government, and industry investment in injury prevention. The persisting burden of DALYs related to transport and unintentional injuries indicates a need to prioritise innovative measures for the primary prevention of adolescent injury.

Studies of the effectiveness of transport sector interventions in low- and middle-income countries: An evidence and gap map

BACKGROUND

There are great disparities in the quantity and quality of infrastructure. European countries such as Denmark, Germany, Switzerland, and the UK have close to 200 km of road per 100 km², and the Netherlands over 300 km per 100 km². By contrast, Kenya and Indonesia have <30, Laos and Morocco <20, Tanzania and Bolivia <10, and Mauritania only 1 km per 100 km². As these figures show, there is a significant backlog of transport infrastructure investment in both rural and urban areas, especially in sub-Saharan Africa. This situation is often exacerbated by weak governance and an inadequate regulatory framework with poor enforcement which lead to high costs and defective construction.The wellbeing of many poor people is constrained by lack of transport, which is called "transport poverty". Lucas et al. suggest that up to 90% of the world's population are transport poor when defined as meeting at least one of the following criteria: (1) lack of available suitable transport, (2) lack of transport to necessary destinations, (3) cost of necessary transport puts household below the income poverty line, (4) excessive travel time, or (5) unsafe or unhealthy travel conditions.

OBJECTIVES

The aim of this evidence and gap map (EGM) is to identify, map, and describe existing evidence from studies reporting the quantitative effects of transport sector interventions related to all means of transport (roads, rail, trams and monorail, ports, shipping, and inland waterways, and air transport).

METHODS

The intervention framework of this EGM reframes Berg et al's three categories (infrastructure, prices, and regulations) broadly as infrastructure, incentives, and institutions as subcategories for each intervention category which are each mode of transport (road, rail trams and monorail, ports, shipping, and inlands waterways, and air transport). This EGM identifies the area where intervention studies have been conducted as well as the current gaps in the evidence base.This EGM includes ongoing and completed impact evaluations and systematic reviews (SRs) of the effectiveness of transport sector interventions. This is a map of effectiveness studies (impact evaluations). The impact evaluations include experimental designs, nonexperimental designs, and regression designs. We have not included the before versus after studies and qualitative studies in this map. The search strategies included both academic and grey literature search on organisational websites, bibliographic searches and hand search of journals.An EGM is a table or matrix which provides a visual presentation of the evidence in a particular sector or a subsector. The map is presented as a matrix in which rows are intervention categories (e.g., roads) and subcategories (e.g., infrastructure) and the column outcome domains (e.g., environment) and subcategories as (e.g., air quality). Each cell contains studies of the corresponding intervention for the relevant outcome, with links to the available studies. Included studies were coded according to the intervention and outcomes assessed and additional filters as region, population, and study design. Critical appraisal of included SR was done using A Measurement Tool to Assess Systematic Reviews (AMSTAR -2) rating scale.

SELECTION CRITERIA

The search included both academic and grey literature available online. We included impact evaluations and SRs that assessed the effectiveness of transport sector interventions in low- and middle-income countries.

RESULTS

This EGM on the transport sector includes 466 studies from low- and middle-income countries, of which 34 are SRs and 432 impact evaluations. There are many studies of the effects of roads intervention in all three subcategories-infrastructure, incentives, and institutions, with the most studies in the infrastructure subcategories. There are no or fewer studies on the interventions category ports, shipping, and waterways and for civil aviation (Air Transport).In the outcomes, the evidence is most concentrated on transport infrastructure, services, and use, with the greatest concentration of evidence on transport time and cost (193 studies) and transport modality (160 studies). There is also a concentration of evidence on economic development and health and education outcomes. There are 139 studies on economic development, 90 studies on household income and poverty, and 101 studies on health outcomes.The major gaps in evidence are from all sectors except roads in the intervention. And there is a lack of evidence on outcome categories such as cultural heritage and cultural diversity and very little evidence on displacement (three studies), noise pollution (four studies), and transport equity (2). There is a moderate amount of evidence on infrastructure quantity (32 studies), location, land use and prices (49 studies), market access (29 studies), access to education facilities (23 studies), air quality (50 studies), and cost analysis including ex post CBA (21 studies).The evidence is mostly from East Asia and the Pacific Region (223 studies (40%), then the evidence is from the sub-Saharan Africa (108 studies), South Asia (96 studies), Latin America & Caribbean (79 studies). The least evidence is from Middle East & North Africa (30 studies) and Europe & Central Asia (20 studies). The most used study design is other regression design in all regions, with largest number from East Asia and Pacific (274). There is total 33 completed SRs identified and one ongoing, around 85% of the SR are rated low confidence, and 12% rated as medium confidence. Only one review was rated as high confidence. This EGM contains the available evidence in English.

CONCLUSION

This map shows the available evidence and gaps on the effectiveness of transport sector intervention in low- and middle-income countries. The evidence is highly concentrated on the outcome of transport infrastructure (especially roads), service, and use (351 studies). It is also concentrated in a specific region-East Asia and Pacific (223 studies)-and more urban populations (261 studies). Sectors with great development potential, such as waterways, are under-examined reflecting also under-investment.The available evidence can guide the policymakers, and government-related to transport sector intervention and its effects on many outcomes across sectors. There is a need to conduct experimental studies and quality SRs in this area. Environment, gender equity, culture, and education in low- and middle-income countries are under-researched areas in the transport sector.

Road Safety as a Public Health Problem: Case of Ecuador in the Period 2000–2019

Background: Road safety is a significant public health problem because it causes negative consequences on victims and families. The objective was to analyze the most significant changes in traffic crashes in Ecuador during the period from 2000 to 2019. With data obtained from the National Institute of Statistics and Census, we performed the analysis to identify: the number of traffic crashes, the number of victims, and other study variables. Methods: Descriptive and analytical statistics and the contrast of proportions were used to analyze data from 2000 to 2019. Results: According to the ideal joinpoint analysis model, there was a significant decrease in the number of recorded traffic accidents from 2015 to 2019 of −8.54 per year, while the tendency to die increased in females (2.05 per year) and males (3.29 per year). The most common crash was a collision, and the automobile appeared as the most involved vehicle from 2015 to 2019. The hypothesis test contrast is used to determine if statistically significant differences exist between age groups by gender of the driver injured in the period 2017–2018. Conclusions: This study determines the most significant changes in the variables related to traffic crashes, where mortality due to this cause in the last four years has had a growth rate of 1.8% compared to collisions that presented a rate of −31.12%. The contrast of the hypothesis test shows significant differences in the injury level between males and female drivers, depending on the age group.

Geographical mapping of road traffic injuries in Lilongwe, Malawi

BACKGROUND

Road traffic injuries are a leading cause of death and disability, especially in low- and middle-income countries. Identifying injury hotspots are valuable for introducing preventive measures. This is usually accomplished by using police data, but these are often unreliable in low-income countries. This study aimed to identify hotspots for injuries by collecting geographical data in the emergency room.

METHODS

This was a cross-sectional study of adult road traffic injury patients presenting to the Casualty Department in the central hospital in Lilongwe, the capital of Malawi. An electronic tablet with downloaded maps and satellite photos was used to establish the exact location of the injuries. The geographical data were analyzed with geographic information software.

RESULTS

We included 1244 road traffic injured patients, of which 23.9% were car passengers or drivers, 18.6% were motorcyclists, 17.8% were pedestrians and 18.0% were cyclists or bicycle passengers. Heatmaps of the injuries identified 5 locations where the incidence of injuries was especially high, and 148 patients were injured in these hotspots during the 90 days of inclusion. Four of these hotspots were along the main road through the capital. Age over 55, rural setting, alcohol use before the injury, high speed limit at the site of injury and being a pedestrian or motorcyclist were significantly associated with a higher degree of injury severity. Around half of the patients that were injured in a four-wheeled vehicle did not use a seat belt, and these patients had a much higher risk of getting a more severe injury.

CONCLUSION

We have identified specific locations with a high incidence of road traffic injuries in Lilongwe, Malawi, with a simple methodology and within a short time frame. The study demonstrates the feasibility of collecting geographical data at admission to hospital.

Adolescent's perception of road risk on their routes to school in Makwanpur, Nepal; a qualitative study

BACKGROUND

Busy and poor road infrastructure along routes to school poses high risk of traffic injury for children and adolescents. Ensuring every young person's safe journey to and from school is fundamental to achieving reductions in road injuries and Sustainable Development Goal 3.6. However, there is little evidence reporting adolescent's views about their school travel from low and middle income countries. This study aims to understand adolescent's perceptions of injury risks on their journey to school in Nepal.

METHODS

We used Photo-Elicitation Interview (PEI) methods to collect data from fourteen purposively identified adolescents (12-16 years) who walk to Tribhuwan Secondary School along the East-West Highway which is known to be at high risk of crashes in Makwanpur, Nepal. The participants used a camera to record parts of their journey, which they perceived as dangerous or safe. Photographs were used as prompts during an interview afterwards. Interviews were audio-recorded, transcribed, translated and analysed thematically.

RESULTS

The identified themes were categorised as either environmental or behavioural factors. The adolescents were scared to walk on narrow roadsides because of speeding vehicles. They also found crossing the road dangerous because of the lack of designated pedestrian crossings and disregard shown by drivers. Poor visibility caused by random roadside parking and trees also increased the sense of road danger.

CONCLUSION

Adolescents expressed multiple concerns which made their journeys difficult and dangerous. They illustrated issues such as poor road condition, inadequate pedestrian crossings and traffic signs, narrow roadsides, vehicle speeding and overtaking, failing to obey traffic rules and regulation -providing evidence that could be shared with the authorities to improve road safety near schools.

Prevention of childhood unintentional injuries in low- and middle-income countries: A systematic review

Injuries are a leading cause of death and disability among children. Numerous injury prevention strategies have been successful in high-income countries, but the majority of unintentional injuries happen to children living in low- and middle-income countries (LMICs). This project aims to delineate the childhood injury prevention initiatives in LMICs. For inclusion, peer-reviewed articles needed to address unintentional injury, include children <18, assess a prevention-related intervention, contain a control group, and be published after 1988. Two pairs of reviewers evaluated articles independently to determine study eligibility. 74 articles were included. 30 studies addressed road traffic injuries, 11 drowning, 8 burns, 3 falls, 8 poisonings, and 21 an unspecified injury type. The findings show positive effects on injury outcome measures following educational interventions, the need for longer follow-up periods after the intervention, the need for effectiveness trials for behavior change, and the need for an increase in injury prevention services in LMICs. This is the first systematic review to summarize the prevention initiatives for all types of childhood unintentional injuries in LMICs. Increased attention and funding are required to go beyond educational initiatives with self-reported measures and little follow-up time to robust interventions that will reduce the global burden of unintentional injuries among children.

Looking back on 10 years of global road safety

Every year more than 1.35 million people lose their lives on the road and tens of millions more are injured, some permanently. Since the early 2000s there has been renewed focus on the issue, with the United Nations, World Health Organization and the World Bank placing the issue higher on their agendas. Guided by the United Nations General Assembly, World Health Assembly resolutions and ministerial-level conferences on the global road safety crisis, multisectoral partnerships have synthesised the evidence, advocated for action (there are two Sustainable Development Goal targets with an ambitious goal of reducing deaths and injuries from road traffic crashes by 50%), raised public awareness, generated funding, piloted interventions and monitored progress. And yet the total number of deaths has plateaued despite some sporadic country-level successes. More needs to be done-more people need to be trained in countries to deliver, monitor and evaluate a systems approach to road safety, more solid evidence of what works in low-resource settings is needed (including sustainable transportation options) and there needs to be a greater focus on optimising care and support for those injured in crashes-if we are to begin to see numbers come down in the next decade.

What Does Urban Transformation Look Like? Findings from a Global Prize Competition

Different disciplines are grappling with the concept of ‘urban transformation’ reflecting its planetary importance and urgency. A recent systematic review traces the emergence of a normative epistemic community that is concerned with helping make sustainable urban transformation a reality. Our contribution to this growing body of work springs out of a recent initiative at the World Resources Institute, namely, the WRI Ross Prize for Cities, a global award for transformative projects that have ignited sustainable changes in their city. In this paper we explain the competition-based approach that was used to source transformative initiatives and relate our findings to existing currents in urban transformation scholarship and key debates. We focus on one of the questions at the heart of the normative urban transformation agenda: what does urban transformation look like in practice? Based on an analysis of the five finalists, we describe urban transformation as encompassing a plurality of contextual and relative changes, which may progress and accelerate positively, or regress over time. An evaluative approach that considers varying ‘degrees’ and ‘types’ of urban transformation is proposed to establish meaning within single cases and across several cases of urban transformation.
