Adaptable stop/yield signs have been proposed by some traffic professionals to improve travel time, reduce air pollution, increase fuel economy, and adjust to different traffic conditions such as peak hours, weather, or emergency vehicles. With the advent of Connected Vehicle (CV) technology, we now have the ability to have these signs change based on vehicle-to-infrastructure and vehicle-to-vehicle communications. The placement of a sign type has been traditionally based upon traffic conditions. However, more and more stop signs are being placed instead of yield signs due to liability risk, resident concerns, and potential worst-case crash scenarios.
While adaptable signs have great potential, they must be properly designed and tested to ensure that:
