An on-board intelligent vehicle system includes a sensor assembly to collect data and a processor to process the data to determine the occurrence of at least one event. The data may be collected from existing standard equipment such as the vehicle communication bus or add-on sensors. The data may be indicative of conditions relating to the vehicle, roadway infrastructure, and roadway utilization, such as vehicle performance, roadway design, roadway conditions, and traffic levels. The detection of an event may signify abnormal, substandard, or unacceptable conditions prevailing in the roadway, vehicle, or traffic. The vehicle transmits an event indicator and correlated vehicle location data to a central facility for further management of the information. The central facility sends communications reflecting event occurrence to various relevant or interested users. The user population can include other vehicle subscribers (e.g., to provide rerouting data based on location-relevant roadway or traffic events), roadway maintenance crews, vehicle manufacturers, and governmental agencies (e.g., transportation authorities, law enforcement, and legislative bodies).

Devices, systems, and methods are disclosed for identifying a driver versus a passenger within a smart vehicle. This involves a determination of the relative positions of the wireless communication devices within the smart vehicle using near-field communication (NFC) or GPS, AGPS, etc. The wireless communication device detected closest to the driver seat is assumed to be the device owned by the driver. Once identified, the driver can be billed for tolls and other road services, based on the location of the smart vehicle. For instance, as the smart vehicle approaches a toll, a notification can be sent to all of the wireless communication devices. A response from a particular wireless communication device will result in the corresponding user's account being billed for the toll. Further, the smart vehicle can communicate with near-field transceivers placed, for instance, alongside a High-Occupancy Vehicle (HOV) lane. A driver of the vehicle can be billed, fined, or ticketed based upon a determination of an absence of passengers in the smart vehicle.
