An Elastic Data Elements Design Method for Highway Infrastructure Monitoring Data

Highway infrastructure is an important component of transportation infrastructure. Collecting dynamic monitoring data for some kinds of highway infrastructure is an important prerequisite for the intelligent operation and maintenance of highway infrastructure. However, there are many kinds of highway infrastructure, the contents and forms of monitoring data vary, and the transmission requirements are different. Wireless transmission has the advantages of strong scalability and elastic deployment but also disadvantages, such as limited band resources and low stability. A design method of data elements with variable structure and data size is proposed to realize the effective transmission of all kinds of monitoring data through wireless means. Based on a design case of elastic time data element and a simplified application model of monitoring data transmission, it is proved by theoretical analysis that the elastic data element constructed by this method can significantly reduce the load of PDU under certain application conditions.
