Abstract

Emergency telephone system is the special symbol facilities of highway. It is the special equipment in highway for providing emergency rescue during the vehicle accidents and sending the information to the relevant manage departments. In this paper, the development history of the highway is first introduced, and a classification framework of the emergency telephone system is given. According to the transmission mode the system is divided into three types: cable type, optical fiber type, and wireless type, and subsequently the advantages and disadvantages of various types in the system are compared, end of this paper, the key issues of the system and the future trend of development is presented.
