Positive Guidance Action Plan
Description
Provide additional positive guidance (e.g., 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.
Steps For Implementation
- Use safety screening methods to identify, prioritize, and select roadway segments where positive guidance devices may be effective in reducing roadway and lane departures.
(Participating organizations: TxDOT and city and county agencies) - Select countermeasures based on cost to implement, time to implement, and barriers for selected roadway segments and public input. (Note: A comprehensive listing of potential countermeasures grouped by cost and time to implement with effectiveness measures is linked at the bottom of this section.) Consider the needs of all users, including bicyclists and adjacent residents.
(Participating organizations: transportation and law enforcement agencies, and public information officers) - Program funds for implementing countermeasures or incorporating them into existing projects.
(Participating organizations: TxDOT, city and county agencies, and metropolitan planning organizations [MPOs]) - Implement countermeasures in new and existing projects.
(Participating organizations: transportation agencies at state, city, and county levels) - Publicize countermeasures to build additional support for projects.
(Participating organizations: media outlets, and principal investigators and staff at state, city, and county transportation agencies) - Evaluate effectiveness.
