Vehicle Dynamic Mobility Models (M-Models) Subsidiary of Vehicle MovementEnergy Transfer to Pavement.

Transportation agencies are spending considerable resources to monitoringstatus of roadways in many ways. Roadway monitoring is quite often done with low-tech and costly methods. Recently has more sophisticated approaches been implemented to achieve the future highway operational needs. Smart Pavement Material (SPM) is a stand-alone micro node device that can be embedded in the pavement as intelligent highway infrastructure. Therefore, SPM need to operate with a long range life time with a reliable operational and real time communication capability. The SPM will be host of a multifaceted highway sensors and micro low power wireless mesh communication station. The SPM will be equipped with its own on-chip micro-power generator unit to maintain the SPM node operation without external power or internal battery power source. The furnishing of the SPM nodes will be a large distribution of the nodes along the highway with distances of 2- 4 part. The SPM operation concepts is based on its pavement sensors, which are collectthe information of the traffic and pavement conditions and provide a communication carrier along roadway for transferring the information along theSPM network. SPM network includes the large scale SPM nodes and the external node such as a fixed roadway field station or traveling vehicles. SPM will have several major applications such as pavement management and maintenance systems, advanced traffic control and monitoring system and vehicleto vehicle communication systems. Under SPM feasibility the system components have been investigated and conceptual planning was conducted. As partof that study, it was specified that an in-chip power generator will be the main components for SPM operation and product ability. The study recognized the main energy resource is vehicle mobility energy transferring to pavement. SPM will convert that energy to electricity. This study shows thetransferring energy on the highway network can be source for SPM power micro generator and a power generation of 50 -100 µW is feasible.
