• Identification of effective work zone pavement marking removal techniques.
• Review of raised retroreflective pavement marker practices in other states.
• Identification of current uses and effectiveness of safety corridors.
• Hosting of a wrong-way driving forum.
• Assessment of pedestrian crashes on freeways and high-speed arterials.
• Review of the design and application of lane control signs on frontage roads.
• Review of the application of embedded light-emitting diodes in signs.
