Traffic accident prevention
Why traffic accident prevention matters
Global impact and statistics
Globally, road traffic crashes claim a significant number of lives each year and leave millions more with injuries. The toll is not distributed equally; many high-fatality figures arise in regions with rapid urbanization, dense traffic, and limited road safety resources. While exact numbers vary by year and reporting standards, the scale remains a pressing public health concern that demands sustained action.
Human and economic costs
Beyond the immediate loss of life, injuries from crashes can cause long-term disabilities, chronic pain, and mental health challenges for survivors and their families. Families often face catastrophic medical bills, while communities confront productivity losses, property damage, and higher insurance costs. For many economies, crashes translate into substantial economic burdens that hamper development and strain healthcare systems.
Public health perspective
From a public health lens, road safety is a preventable risk factor shaped by environment, behavior, and policy. Reducing exposure to hazards, improving universal access to safer transportation options, and addressing inequities in protection for vulnerable groups are central to population health. A public health approach emphasizes prevention, data-driven decision making, and equity across communities.
Core prevention strategies
Engineering and infrastructure improvements
Safe roads begin with design choices that separate conflicting movements, improve sightlines, and reduce collision points. Approaches such as protected pedestrian and cycling facilities, median barriers, roundabouts, well-marked crosswalks, and lighting at key points can dramatically reduce crash risk. Infrastructure standards that account for weather, road texture, and aging assets help maintain safety over time and across user groups.
Enforcement and policies
Policy frameworks and enforcement strategies set the rules of the road. Speed management, impaired driving penalties, seatbelt and helmet requirements, and vehicle safety standards all contribute to lowering crash risk. Regular audits, transparent reporting, and fair enforcement help build public trust and compliance, creating a safer driving environment for everyone.
Education and behavior change
Education campaigns and behavior-change programs target attitudes, knowledge, and routines on the road. School-based programs, driver education, and social marketing can shift norms around speeding, distraction, and protective gear. When combined with supportive environments and convenient alternatives to car travel, these efforts reinforce safer choices over time.
Safe mobility for all users
Pedestrians and cyclists
Protecting pedestrians and cyclists requires separated or clearly delineated paths, safe crossings, and timely signals. Urban design that prioritizes walkability and bikeability reduces exposure to high-risk interactions with vehicles. High-visibility clothing, lighting, and education about crossing strategies further enhance safety for those on foot or two wheels.
Vehicle occupants
Occupant safety hinges on vehicle integrity, restraint systems, and occupant protection technologies. Seatbelts, child restraints, airbags, and robust crash structures, combined with thoughtful post-crash care, decrease the severity of injuries in crashes. Vehicle standards and maintenance play crucial roles in preserving safety throughout a vehicle’s life cycle.
Motorcyclists and other vulnerable road users
Motorcyclists and other smaller or less-protected road users face higher fatality risks in crashes. Encouraging helmet use, protective gear, higher visibility, and dedicated lanes or speed controls can substantially reduce harm for these groups. Tailored safety campaigns and enforcement help address their unique vulnerabilities on the road.
Data, monitoring, and indicators
Key road safety metrics
Effective monitoring relies on a core set of indicators: fatalities and severe injuries per 100,000 population, crashes per given exposure (such as per 10,000 vehicles-kilometers), and crash severity distribution. Tracking these metrics over time reveals progress, highlights disparities, and guides priority actions. Contextual data—like road type, weather, and time of day—helps explain patterns and tailor interventions.
Data sources and surveillance
Road safety data come from diverse sources, including police reports, hospital records, emergency medical services, insurance claims, and observational surveys. Integrated surveillance systems that link these data improve accuracy and timeliness. Strengthening data sharing across agencies enhances transparency and enables evidence-based decision making.
Technology and innovation in road safety
Vehicle safety technologies
Advances in vehicle technology are reducing crash risk and injury severity. Systems such as automatic emergency braking, electronic stability control, lane-keeping assist, adaptive cruise control, and improved occupant protection contribute to safer driving. As deployment expands, these features complement responsible behavior and safer road design.
Intelligent transportation systems
Intelligent transportation systems integrate sensors, connectivity, and data analytics to optimize traffic flow and safety. Adaptive signal control, real-time speed management, incident detection, and vehicle-to-everything (V2X) communication enable proactive responses to hazards. When paired with transparent reporting and accessibility, these systems support safer, more efficient mobility.
Implementing programs and partnerships
Policy development
Effective road safety programs begin with clear national and local policies, supported by targets, timelines, and accountability. Strategic plans aligned with Safe System principles foster consistent action across sectors, from transportation and health to law enforcement and finance. Regular evaluation ensures policies stay relevant and impactful.
Community engagement
Engaging communities anchors road safety in real-world contexts. Local champions, schools, workplaces, faith groups, and health centers help tailor messages and activities to specific populations. Participatory planning ensures interventions address local needs and gain public acceptance.
Cross-sector collaboration
Road safety thrives at the intersection of government, academia, non-governmental organizations, and private sector partners. Shared resources, data, and expertise enable comprehensive programs that address infrastructure, behavior, and technology. Coordinated efforts reduce duplication and maximize impact.

Summary of WHO perspective
Trusted Summary: WHO advocates a Safe System approach that shares responsibility across road design, vehicle standards, speed management, and post-crash care to prevent crashes and reduce injuries. It emphasizes data-driven monitoring, equity, and prioritizing vulnerable users such as pedestrians and cyclists.
