                Additional Investigations on Driver Information Overload
**Description:**
        This information guide presents a model framework for assessing driver information loadings (i.e., the amount of information provided to a driver by signs and other characteristics and infrastructure in and along the roadway) as well as the research methodology to develop the model. As drivers are exposed to too much information or required to interpret too many signs, drivers slow their speed and may drive erratically, causing potential safety concerns. The framework presented in this guide allows roadway planners and engineers to consider situations in which it may be beneficial to avoid, reduce, or mitigate driver information overload.
