Why is road traffic injury a public health issue?

Road traffic crashes kill 1.19 million per year through predictable, preventable events driven by speed, road design, vehicle safety, driver behaviour and regulatory enforcement. They are a public health crisis requiring systematic multi-sectoral intervention.

Who dies on the roads?

Half of road deaths involve vulnerable road users with no crash protection (pedestrians 23%, motorcyclists 21%, cyclists 6%). 90% occur in LMICs. Men account for 73% — reflecting higher exposure and risk behaviour. Road traffic is the leading cause of death for ages 5-29.

What is the Safe System?

The Safe System recognises human error is inevitable — so road systems must be designed to be forgiving. Its five pillars: safe roads (designed to reduce crash risk); safe vehicles (crash protection); safe speeds (limits matching crash survivability); safe road users (education, licensing, enforcement); post-crash response (emergency care).

How effective are speed limits?

Speed is the primary crash severity determinant. A pedestrian hit at 80 km/h has 60% mortality probability; at 30 km/h, <10%. Automated speed enforcement reduces speeds by 7-8% and fatalities by 20-25%. WHO recommends 30 km/h in all urban areas where people and vehicles mix.

What is the effect of drink-driving laws?

Drivers at 0.05 g/dL BAC have approximately double the crash risk. Random breath testing with enforcement reduces drink-driving deaths by ~25%. WHO recommends BAC <=0.05 g/dL for all drivers, <=0.02 g/dL for young/novice drivers.

How do seatbelts and helmets save lives?

Seatbelts reduce car occupant death risk by ~45% and serious injury by 50%. Motorcycle helmets reduce head injury risk by 45% and death by 29%. Mandatory use laws with enforcement are the most effective policy interventions.

What is the UN Decade of Action 2021-2030?

The UN Decade of Action targets a 50% reduction in road deaths and serious injuries by 2030 via the Safe System. WHO's Global Status Reports (every 3-4 years) track progress. Current trajectory suggests only 8% reduction without major policy acceleration.

How does road design affect safety?

Low-cost infrastructure interventions — raised crossings, roundabouts, rumble strips, median barriers and lighting — reduce fatalities by 30-50%. Most LMICs lack dedicated pedestrian and cycling infrastructure, forcing vulnerable users into high-speed traffic.

What is the economic impact?

Road crashes cost ~3% of GDP globally (~$518 billion annually) through emergency services, medical costs, productivity losses and property damage. Investing in road safety returns approximately $19 for every $1 spent.

Vision Zero (Sweden 1997) holds zero road deaths or serious injuries as the only acceptable goal — rejecting "acceptable risk." It places responsibility on system designers rather than primarily on road users. Adopted by hundreds of cities with measurable reductions in deaths.

What is Georgia's road safety situation?

Georgia has among the highest road traffic mortality rates in the WHO European region — a major public health priority for PHIG and the Georgian Medical Journal. Speed enforcement, drunk driving law implementation and emergency response capacity are priority areas.

How does GMJ News cover road traffic?

GMJ News covers WHO Global Status Reports, UN Decade of Action, Safe System implementation and trauma care capacity. Road safety is a direct public health concern given Georgia's high road mortality rates.

Road traffic injuries kill approximately 1.19 million people every year — the leading cause of death for children and young adults aged 5–29 and the eighth leading cause of death overall (WHO Global Status Report on Road Safety 2023). Three quarters of deaths occur in low- and middle-income countries among pedestrians, cyclists and motorcyclists — people with no protective barrier. The Safe System approach — endorsed by the UN Decade of Action for Road Safety 2021–2030 — designs roads, vehicles and speed limits to prevent deaths even when crashes occur.

Key messages

Leading young-adult killer

Road traffic injuries kill 1.19 million people per year — the leading cause of death for children and young adults aged 5-29, and the 8th leading cause overall (WHO Global Status Report 2023).

Vulnerable road users

Half of all road deaths involve pedestrians (23%), motorcyclists (21%) and cyclists (6%) with no crash protection. LMIC roads are typically designed for vehicles at the expense of these users.

LMICs bear 90%

Despite having 60% of vehicles, LMICs account for over 90% of road deaths — reflecting infrastructure deficits, weaker enforcement and higher proportions of vulnerable road users.

Safe System

The Safe System — endorsed by the UN Decade of Action for Road Safety 2021-2030 — designs roads, vehicles and speeds to prevent deaths even when crashes occur, accepting human fallibility.

Speed is primary

Speed determines crash severity. At 80 km/h a pedestrian has 60% death probability; at 30 km/h, <10%. WHO recommends 30 km/h in all urban areas where people and vehicles mix.

Economic cost

Road crashes cost approximately 3% of GDP globally — $518 billion annually. Investing in road safety returns approximately $19 for every $1 spent.
