Minnesota Horizontal Curve Safety Improvement
Project Description
A low-cost technology that may help drivers select an appropriate speed when approaching a horizontal curve is the dynamic curve warning sign (DCWS). A DCWS generally consists of a warning sign combined with a speed measuring device (e.g., radar) that activates a variable message (e.g., slow down) when vehicles are traveling above a set threshold. This project will evaluate the speed and/or crash impacts of three permanently installed DCWSs in two Minnesota counties. This project has been proposed as a supplement and expansion of an on-going Federal Highway Administration (FHWA) national DCWS field study.
