TRIDENT - Transport Intermodality Data sharing and Exchange Networks
Overview
Background & policy context:
European transport information is characterised by its local or restricted qualities. In order to develop systems that have wider regional, national and pan-European potential, it is first necessary to develop common specifications and standards for sharing and exchanging transport data. Earlier work has successfully developed standards for individual transport modes.
TRIDENT aimed to extend these standards to operate in a multi-modal transport environment, laying the foundation for the development of more comprehensive transport information systems and the achievement of significant improvements to the availability and accuracy of transport information across Europe.
Also, common and sharing and exchange specifications are a key enabling factor for service interoperability and customer roaming.
Objectives:
TRIDENT’s intention was to develop specifications and software modules to enable the sharing and exchange of real-time multimodal traffic and traveller information through the whole Transport and Travel Information content chain.
Methodology:
Two different paths to achieve this goal were selected: One based on the “messaging approach” (EDI, DATEX) and the other one based on the use of more modern object-oriented (OO) technologies.
The aim of the EDI approach is to offer existing DATEX users a way to exchange a larger variety of content using their existing DATEX nodes as well as provide a first step of the migration path towards the OO technologies.
The aim of the OO approach is to offer new actors means to exchange the whole range of traffic and traveller information using modern technologies, yet fully taking advantage of the high level of know-how obtained in developing the DATEX (road traffic information exchange) and TransModel (Public Transport reference model) standards.
After the development of the draft specifications, a five test site validation and demonstration of applications based on the specifications was planned.
