Achieving syntax interoperability of existing traffic controllers and intelligent transport systems

Abstract

This paper presents a solution for achieving syntax interoperability between different systems. It is necessary to ensure that one system will accept data from the other systems and so to ensure efficient data exchange to work together, without changing the exchanged information. The goal of this research is to present a concrete solution of achieving syntax interoperability between existing traffic controllers and control traffic management system using DATEX II standard for Europe, based on Open Traffic Systems 2 protocol communication. The exchange of data and their intelligibility between the systems using the standard is the key for interoperability. The aim of this paper is to present how to convert binary format of data in any format which other traffic management system can understand. Syntax interoperability deals with the agreed data formats of communication so that machine-to-machine (system to system) communication can be parsed and understood by each machine (system). To achieve syntax interoperability with intelligent transport systems, it requires integrations at the following three levels: [1] 1.Field to field (roadside ITS station to roadside infrastructure)2.Field to vehicle (roadside ITS station to vehicle ITS station)3.Field to command center (roadside ITS station to back office) In this paper, research will be focused on achieving syntax interoperability at the three levels previously mentioned. The solution is based on converting one data format (binary) to another data format (XML, etc.) which understood by systems.
