The V2I Hub software (formerly known as IVP) will bridge the gap between infrastructure messages and vehicle messages and allow the two systems to effectively communicate.  This software is designed to be used by jurisdictions deploying connected vehicle systems.  By initializing the system with standard data such as intersection geometry and the correlation between signal phases and lanes, this software will be able to form and transmit Signal Phase and Timing (SPaT) messages that are key to connected vehicle applications such as red light violation warning.  Through the use of Traveler Information Messages (TIM), the system can also develop and send infrastructure information about advisory speeds, attributes of physical elements such as bridge heights, and other data that can be used by applications such as curve speed warning and over-height warnings.
