Permanent Signs
Brighter Signs Improve Safety

Traffic signing delivers from $104 to $246 for every dollar spent—a highly cost-effective traffic safety improvement. Studies show that brighter signs help reduce crashes by as much as 25 to 48 percent. 3M™ Diamond Grade™ DG3 Reflective Sheeting helps improve safety at STOP-controlled intersections and fluorescent yellow sheeting enhances the visibility of advance warning signs.

• Delivers increased luminance during the day, dawn and dusk for better positive guidance
• Generates twice the retroreflective efficiency of other sheetings at night through full cube technology
• Delivers optimal performance where and when drivers need it most

Pavement Markings
Better Markings Provide Positive Guidance

Pavement markings made from high performance, all-weather materials provide guidance for drivers and raise awareness in transitions and danger spots such as hidden intersections, curves and railroad crossings. 3M™ Stamark™ High Performance Wet Reflective Tape and 3M™ All Weather Paint offer durability and all weather performance.
The solution:

• Provides high visibility-day or night, wet or dry
• Alerts drivers to changing road geometries or approaching conditions
• Increases motorist guidance with stop bars, crosswalks, symbols and legends

Driver Feedback Signs
Driver Feedback Signs Reduce Traffic Speeds

The FHWA Manual on Uniform Traffic Control Devices states that “Changeable message signs displaying actual speeds… enhance driver compliance with speed limits.” Each one-mileper-hour decrease in traffic speed typically reduces accidents by five percent. 3M™ Driver Feedback Signs provide real-time feedback to slow speeding drivers as they approach transitions from rural to populated areas. The proven technology:

• Makes roadways safer by reducing driving speeds
• Commands attention with high-visibility fluorescent yellow-green pixels
• Logs speed data to substantiate speed reductions

• S.E. Jenkins comparison of LED-only with 3M hybrid (DOC 52 K)
• Dynamic Speed Monitoring Displays (PDF 276 K)
