Abstract:

As the use of express lanes is expanding in Florida, FDOT is developing material specifications for Express Lane Markers (ELM). To complete the specifications, highway product safety and impact testing was conducted to ensure an optimum service life of ELMs and evaluate the performance of several products and installation methods. The Department's past installations of Express Lane Markers were on concrete pavements. Current and future installations will be on Open Graded Friction Course (OGFC) asphalt surfaces. A test strip with OGFC was constructed to allow product testing on this type of surface. Impact testing of various products, installation methods, surface types and weather conditions was performed. It is recommended that product tests on asphalt and concrete surface have a combined average that meets a minimum of 150 tire impacts and 50 bumper impacts resistance. In addition, the product’s performance on asphalt or concrete should meet a minimum of 150 tire impacts and 45 bumper impacts resistance. The Manual for Uniform Traffic Control Devices (MUTCD) currently allows the use of orange, white and yellow channelizing devices for emphasis of pavement marking patterns. The Department has used the color orange for existing installations on concrete surfaces to enhance visibility and provide a more aesthetic appearance after ELM receive black marks from impacting vehicles. The MUTCD was expected to be modified for the next version to only allow the use of the color orange in work zones. This report proposes a research plan to test the visibility of delineators with different color patterns and define the optimum color.
