Lane departure

Emphasis areas

Traffic data system Vulnerable Road Users Agressive driving Driving under the influence of alcohol Occupant protection
Lane departure crashes occur when a driver veers off the roadway into another lane or a green area. Causes include distraction, lane conditions, loss of control, weather, road obstacles, driver state, speed, and mechanical problems.
Reduce the 5-year average of fatalities related to lane departure to 80 or fewer by 2028.
  1. Develop a systemic program to remove and/or protect drivers from fixed objects (e.g., guardrails, clearing roadside areas) on major and minor arterial roads over the next five years.
  2. Implement proven road safety measures during the design phase of ACT, DTOP, and municipal projects (e.g., rumble strips, wider markings, SafetyEdge®, median barriers, delineation, and improved design for horizontal curves).
  3. Recommend complete street concepts to reduce speeds.
  4. Educate drivers on how to safely regain control of the vehicle if they leave the road.
  5. Evaluate and select corridors on major and minor arterial roads with the highest incidence of lane departure crashes using OSV data and conduct systemic road safety evaluations.
  6. Develop a systemic pavement marking program for major and minor arterial roads over the next five years.
