trafficrelated

Traffic-related is an adjective used to describe matters connected with road traffic, including motor vehicles, pedestrians, cyclists, transit, and the road network. It is applied across disciplines such as transportation engineering, urban planning, public health, and law enforcement to categorize issues related to safety, mobility, infrastructure, regulation, and enforcement.

Traffic-related safety and health concerns encompass injuries and fatalities resulting from collisions and near misses. Risk factors commonly include excessive speed, impairment from alcohol or drugs, distraction, fatigue, and deficiencies in road design or infrastructure. Globally, road traffic crashes are a major public health issue, with an estimated 1.3 million deaths each year and many more people injured. Vulnerable road users, such as pedestrians and cyclists, experience disproportionately high harm in many settings.

Management, policy, and infrastructure efforts aim to reduce risk and improve efficiency. This includes road design standards, signage, traffic signals, speed management, and enforcement strategies. Transportation planning often relies on models and data to enhance safety and mobility, employing intelligent transportation systems, transit priority, road Diets or traffic calming, and measures like congestion pricing and improved shoulder and pedestrian facilities.

Data and research underpin traffic-related analysis. Sources include crash reports, traffic counts, sensor networks, and anonymized mobile or GPS data. Common metrics cover crash rates, injury severity, travel time reliability, vehicle miles traveled, and congestion levels. Interdisciplinary work in traffic-related fields spans engineering, public health, psychology, economics, and policy evaluation to inform safer, more efficient road systems.
