Abstract

A computer-implemented method, system, and/or computer program product evaluates a real-time condition of a construct of a roadway. A processor receives a set of roadway vibration patterns from a mobile smart sensor that is mounted on a terrestrial vehicle as it travels along a roadway. This set of roadway vibration patterns is created by a physical contact between a roadway surface of the roadway and a tire on the terrestrial vehicle. The processor also receives a set of transient data from a probe on the terrestrial vehicle. This transient data describes a real-time transient environmental condition at the roadway. The set of roadway vibration patterns and the set of transient data are input into an analysis algorithm to determine a real-time physical condition of a construct of the roadway, such that the analysis algorithm removes any effect the set of transient data has on the set of roadway vibration patterns.
