Roaduse

Roaduse refers to the use of road infrastructure and the activity that occurs on public roads. It encompasses all actors that occupy road space, including motorized vehicles, bicycles, pedestrians, public transit, freight, and sometimes emerging modes such as micromobility devices. Roaduse is influenced by vehicle volumes, speeds, trip purposes, and temporal patterns, and it is affected by road design, enforcement, pricing, and land-use context.

Measurement and management: Traffic engineers monitor roaduse using metrics such as vehicle kilometers traveled, traffic volume, speed, density, and travel-time reliability. Level of service and congestion indices are used to assess performance. Management strategies include geometric design, signal timing, speed limits, incident management, and capacity expansion or demand management like tolls, congestion charging, bus lanes, and carpooling.

Policy and planning: Effective roaduse management balances safety and efficiency with sustainability. Policies aim to optimize modal split, reduce emissions, and improve access for non-motorized users. Planning integrates land-use, public transit, active transport networks, and last-mile freight solutions. Data-driven approaches rely on sensor networks, mobile data, and crowd-sourced information.

Governance and social aspects: Roaduse is managed by multiple agencies at local, regional, and national levels. Funding, equity, and accessibility considerations are central, with attention to vulnerable road users. Safety campaigns and enforcement, infrastructure maintenance, and resilience to weather and disasters are ongoing concerns.
