Strategy
Countermeasures
Countermeasures for strategy 2 were identified in the following categories.
Roadway configuration
Revise roadway configuration to provide additional paved recovery area (e.g., convert four-lane roadways to three-lane roadways with design features compatible with surrounding land use context).
Positive guidance
*Provide additional positive guidance (i.e., rumble strips, stripe lines, raised pavement markings, chevrons including light-emitting diode [LED] chevrons, curve delineators, speed feedback signs, edge lines and centerlines, and wider edge lines), and conduct public information campaigns to explain the purpose and how to navigate the roadway safely.
* Action Plan
Target speeds
Establish target speeds and use engineering techniques to manage speeds in areas experiencing or susceptible to roadway and lane departures.
Driver education
Educate drivers about driving around trucks (e.g., avoiding trucks).
