Abstract
Apparatus and methods are disclosed that may be configured to respond to vibrations in a pavement induced by the travel of a vehicle on the pavement. The apparatus may include vibration sensor nodes embedded in the pavement and systems using the response of the sensor nodes to generate vehicle parameters, weight estimates, pavement deflection estimates and vehicle classifications. From these and other data, traffic ticket, tariff and insurance messages about the vehicle may be generated. Processors and processor-units are disclosed. Delivery mechanisms to configure the processor units and entities controlling and/or benefiting from the deliveries are disclosed.
