Many transportation agencies would like to provide map updates (e.g. road change alignment, road closure, detour route) to mapping/navigation companies (e.g. Waze, Google, Apple, TomTom), however the process for communicating this information may be unclear. The ENTERPRISE Pooled Fund Study is conducting this project to develop a consistent communication approach for providing transportation agency map updates to mapping companies that utilize Department of Transportation (DOT) generated data for various applications such as route guidance. Communicating these map updates will help improve the accuracy of information disseminated through traveler information mechanisms such as mobile applications.
