Abstract:Horizontal curves account for more than 25% of highway fatal crashes and have a crash rate that is three times that of other highway segments. Transportation agencies employ dynamic warning systems that utilize roadside speed detection and warning equipment to provide drivers with a warning when they enter a curve at a speed that might be too high for safe travel. The goal of this project is to develop a system to expand the safety improvement potential of a dynamic curve speed warning system that can be implemented systemwide to all reduced speed curves without infrastructure investment. The system emulates a connected vehicle environment by utilizing a smartphone application to deliver dynamic, speed-based, directional warnings at locations in an online database. Transportation agencies are able to enter and manage the warning locations within their jurisdictions in the online warning database through a web-based tool, and it is envisioned that the warning data would be made available to navigation systems and vehicle manufacturers via the cloud.
