Abstract
An embedded system controller-based vehicle tracking system using vehicle positioning. An embedded system controller controls a traffic intersection using an optical system. The embedded system controller receives a vehicle location and a vehicle schedule. The embedded system controller calculates whether the vehicle is on time and reports the on-time status to the driver interface. The driver may -request that the system report a panic or emergency situation to the dispatch center through an external data communications network. The external data communications network may also send vehicle status, such as vehicle position and vehicle condition. A transit company using the system may provide vehicles equipped with the vehicle tracking system with schedules on a daily basis, using a portable data transfer device. The embedded system controller also communicates to the vehicle data network for the communication of vehicle position. A global positioning system receiver may be used to provide the position of the vehicle to the embedded system controller.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
