The present invention relates to the guidance of autonomous vehicles and in particular, relates to guiding an autonomous vehicle along a roadway by means of active devices with a system which works during normal and inclement, weather as well as under any luminous conditions, These active devices are embedded in the passive and/or active road details such as traffic signs, traffic lights, warning lights etc. These active devices provide data relating to road conditions, speed, road layout etc. as well as other information such as availability of parking spaces. Accordingly, through networks of sensors and devices the autonomous vehicle can obtain road details in real-time in any weather, illumination, visibility etc.

An impact tracking system includes a sensor module that mounts to a fixed crash attenuator, sign, guardrail, or other roadway devices installed along a roadway. When the crash attenuator or other asset is impacted by an errant vehicle, the impact tracker, comprising a sensor system, senses and captures the impact data and sends an alert message to a remote receiver. The receiver may comprise known data receiving means, such as computers or phone systems, which may receive emails, text messages, photos, and the like in real or near real time. Received data may be analyzed, stored, and/or re-transmitted to additional receivers, which may include road authorities, such as transportation departments responsible for inspecting and repairing the impact attenuators.
