Strategy E10. Provide Improved Maintenance of Stop SignsNCHRP Report 500 / Volume 5: A Guide for Addressing Unsignalized Intersection Collisions WHERE TO USE
DETAILSMaintenance of stop signs must be at a high standard to ensure that the effectiveness of the signs is retained. According to the Manual on Uniform Traffic Control Devices, stop signs must be kept in proper position, clean, and legible at all times (both day and night). Damaged signs should be replaced without undue delay. To ensure adequate maintenance, a suitable schedule for inspection, cleaning, and replacement of stop signs should be established. Employees of highway agencies, police, and other governmental employees whose duties require that they travel on the highways should be encouraged to report any damaged or obscured signs at the first opportunity. Special attention and necessary action should be taken to see that trees, shrubbery, and construction materials do not obscure stop signs and that the stop signs present proper reflectorization. KEY TO SUCCESSDetermine an effective maintenance schedule that may be adequately sustained by highway agencies. ISSUESNone identified TIME FRAME: ShortThis strategy does not require a long development process. A maintenance schedule can typically be developed in 3 months or less. COSTS: LowCosts for maintenance of stop signs are relatively low. An agency's maintenance costs may increase. EFFECTIVENESSTRIED: The effectiveness of this strategy has not been satisfactorily quantified. COMPATIBILITYThis strategy can be used in conjunction with most other strategies for improving safety at unsignalized intersections.
