Description
The Signs and Markings Program includes a team of multidisciplinary researchers that explores and develops relationships between driver, vehicle, roadway and traffic control devices. Research focuses on how improved understanding of these relationships results in higher levels of safety, improved operations, and cost saving strategies. Much of the research conducted by the Signs and Markings Program is implemented through changes or additions to state, national, and international documents such as the Manual on Uniform Traffic Control Devices and ASTM standards and specifications.
Expertise
Researchers in the Signs and Markings Program have expertise in the following technical areas:
- traffic engineering,
- safety data collection and analysis,
