Liikenneriskien

Liikenneriskien, literally “traffic risks” in Finnish, refers to the set of potential dangers arising from road traffic and mobility. In transport planning and road safety practice, the term encompasses hazards that can lead to injuries, fatalities, property damage, or social and economic disruption. It covers risks affecting drivers, passengers, pedestrians, cyclists, and public transit users, as well as risks related to infrastructure and environmental conditions.

The scope of liikenneriskien includes collision risks (such as vehicle crashes), near-misses, exposure to hazardous road conditions, and risks stemming from interactions between different modes of transport. It also includes indirect consequences like congestion, delays, noise and air pollution, and costs from injuries or infrastructure damage. Risk categories are frequently organized around human factors, vehicle condition, road design, weather and visibility, and maintenance status of the transport system.

Assessment and management of liikenneriskien typically involve hazard identification, risk assessment, and prioritization. Methods may include risk matrices, scenario analysis, root-cause investigations, and data-driven modeling using accident statistics, traffic volumes, and Geographic Information Systems. Responsibility for assessment and mitigation can lie with national or local authorities, transportation agencies, and transport operators, often in collaboration with urban planners and emergency services.

Mitigation measures focus on engineering, enforcement, and education. Engineering solutions include speed management, separation of traffic modes, intersection redesign, improved lighting, signage, and maintenance. Operational measures involve targeted enforcement and incident response, while educational campaigns promote safe behavior among all road users. Liikenneriskien is used to guide planning, policy, and investment to reduce harm and improve mobility.
