The Smartway concept promises the efficient development and implementation of a road infrastructure that utilizes the latest  ITS technology. 
　While the consolidation and cooperation between various regions, road administrators, and non-road administrators become increasingly important for the development of Smartway, the current road communication system suffers from problems such as the ones listed below. 

　

　

●Due to the coexistence of multiple communication protocols and the difference of data definitions, it requires a great amount of time and cost to make coordination between different systems. In some cases, such coordination may be extremely difficult. 
　
●Because the definitions of information interpretations vary, the intersystemic coordination of information interpretations requires great expenditure of time and costs.In some cases, such coordination can be extremely difficult. 
　   　
●It is often the case that the different communication method is employed between the machines made by different makers, where interchangeability is not guaranteed. 
This lack of conformity may hinder the day-to-day operation. It also may cause the increase of machine price since we can not select the machine from many potential makers.
