Safety and Human Factors of Adaptive Stop/Yield Signs Using Connected Vehicle Infrastructure
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:

The net safety benefits are positive.
2. Drivers interpret and respond correctly to the signs.
Drivers pay appropriate attention to the signs without adaptation in the form of relying on past history (e.g., the sign may be different than the prior 10 times the intersection was crossed).
There are no other unintended consequences when signs are deployed.
Driver acceptance of the technology is high.
