An emergency vehicle traffic light preemption system for preemption of traffic lights at an intersection to allow safe passage of emergency vehicles. The system includes a real-time status monitor of an intersection which is relayed to a control module for transmission to emergency vehicles as well as to a central dispatch office. The system also provides for audio warnings at an intersection to protect pedestrians who may not be in a position to see visual warnings or for various reasons cannot hear the approach of emergency vehicles. A transponder mounted on an emergency vehicle provides autonomous control so the vehicle operator can attend to getting to an emergency and not be concerned with the operation of the system. Activation of a priority-code (i.e. Code-3) situation provides communications with each intersection being approached by an emergency vehicle and indicates whether the intersection is preempted or if there is any conflict with other approaching emergency vehicles. On-board diagnostics handle various information including heading, speed, and acceleration sent to a control module which is transmitted to an intersection and which also simultaneously receives information regarding the status of an intersection. Real-time communications and operations software allow central and remote monitoring, logging, and command of intersections and vehicles.

A light emitting diode (LED) based illumination module performs on-board diagnostics. For example, diagnostics may include estimating elapsed lifetime, degradation of phosphor, thermal failure, failure of LEDs, or LED current adjustment based on measured flux or temperature. The elapsed lifetime may be estimated by scaling accumulated elapsed time of operation by an acceleration factor derived from actual operating conditions, such as temperature, current and relative humidity. The degradation of phosphor may be estimated based on a measured response of the phosphor to pulsed light from the LEDs. A thermal failure may be diagnosed using a transient response of the module from a start up condition. The failure of LEDs may be diagnosed based on measured forward voltage. The current for LEDs may adjusted using measured flux values and current values and a desired ratio of flux values. Additionally, the LED current may be scaled based on a measured temperature.

A system for keeping an inventory of vehicles that serve as collateral for loans provided by a lending entity includes a vehicle monitoring device, a database, and a central vehicle data server. The vehicle monitoring device includes a wireless modem, a processor, a GPS receiver, a vehicle diagnostics interface connector, and memory. These components are preferably enclosed in a small housing which may be installed beneath the dashboard of a vehicle. The vehicle diagnostics interface connector connects to the vehicle's OBD interface which is electrically connected to the vehicle's on-board diagnostics processor. The device retrieves vehicle diagnostic data through the vehicle's OBD interface based on the occurrence of certain events during the operation of the vehicle, such as ignition events, voltage change events, and location-based events, such as crossing a geofence boundary or exceeding a mileage or speed threshold. The device transmits the retrieved vehicle diagnostic data to the central vehicle data server via a wireless communication network. Vehicle inventories are managed in the database based on the information transmitted from the vehicle monitoring device.

A novel real-time cargo condition management system and a related method of operation utilizes a unique data synchronization between a remote real-time vehicle on-board diagnostics (OBD) monitoring architecture and a radio frequency identification (RFID) tag attached to a cargo container to track real-time conditions of the cargo container. For example, the cargo container's currently-experienced acceleration and interior temperature can be accurately tracked by a remote monitoring station through a unique data synchronization among a vehicle OBD unit in a truck, an RFID reader installed in the cargo holding area of the truck that periodically scans the RFID tag attached to the cargo container, and an OBD data transceiver unit that wirelessly transmits vehicle OBD data correlated to the RFID tag attached to the cargo container. Similarly, the cargo container's location can be accurately tracked by synchronizing the RFID tag information to the OBD data transceiver unit.
