The LLAMD Euro-Project is a single project involving five major cities, encompassing linked field trials in a coordinated programme of research and development. The goal of the project is to develop and demonstrate aspects of the integration of ATT systems within an integrated road transport environment, based on the field trials in the five cities.
The LLAMD Euro-Project, encompasses linked field trials in 5 major cities in a coordinated programme to develop and demonstrate aspects of the integration of advanced transport telematics (ATT) systems within an integrated road transport environment.
In London, the APPLE subproject has made technical progress in linking dynamic route guidance and urban traffic control where the ASTRID database of SCOOT traffic control data will be linked to the dynamic route guidance system.
The Lyon LEADER subproject has contributed to the overall development of a common system architecture in LLAMD.
In Amsterdam the definition of the WEGWIJS subproject has progressed satisfactorily, building upon the concept of enhancing in vehicle route guidance to become a true advanced travel information system (ATIS) by giving information on parking, park and ride and public transport.
The Munich COMFORT subproject is the largest component of LLAMD involving integration of public transport and private traffic in the areas of urban traffic control, park and ride and travel and traffic information.
In Dublin the DUBSAFE subproject has reviewed possibilities for linking accident recording systems with ATT developments.
The MARGOT subproject has both defined specific links with pilot projects within and outside LLAMD, and has made technical progress in journey time prediction techniques and in dynamic network monitoring. Existing modelling techniques are being modified to encompass the different technical approaches represented within LLAMD. The common workpackages have proved to be an effective method of bringing together the nearly 50 organizations directly participating in LLAMD. Plans for implementing the 2 different approaches based on Euro-Scout (beacon based) and SOCRATES (cellular radio based) are progressing well.
The five LLAMD cities are London, Lyon, Amsterdam, Munich and Dublin. Each city in the group is making available for use a core of infrastructure and administrative services serving established functions. Each city is the "site mode" city for one or more aspects of the coordinated Euro-Project, and is also "participant mode" for other aspects. The common theme of LLAMD is Advanced Travel Information Systems (ATIS). Each of the cities includes the development of one or more aspects of ATIS in its site mode activities.
A second major theme is the development and implementation of systems for public transport, parking and park-and-ride. Other key elements of the project include advanced traffic control, both urban and regional, and road safety aspects.
The focus of the many ATT applications within the LLAMD group is the work on integration of applications into a single environment. The five cities encompass some differences in approach but the common activities are identifying areas in which to seek compatibility and are pursuing this potential aim to the maximum in order to progress towards a single pan-European integrated transport environment.
The project is organised into seven work areas: common workpackages, the work in each of the five field trials, and the development and application of modelling and assessment techniques in the MARGOT sub-project.
The interlinking between the cities and the guarantee of a European dimension is provided by a set of common workpackages which normally involve partners working in two or more of the cities. Common workpackages encompass project administration, systems coordination, methodological approach, common technological approaches, and interlinking with other projects. They provide the mechanism for technical coordination and the assurance of a European dimension to the project, as well as linking to the ATT Area and Topic Groups.
The London APPLE (Advanced Pilot Project for London and Europe) project is directly linked to the separate implementation of the Autoguide pilot system of in-vehicle dynamic route guidance. APPLE specifically concerns the development of a common systems architecture for ATIS, the development of an integrated traffic control centre, and the integration of dynamic route guidance with urban traffic control. It provides for further potential developments including urban fleet management and the integration of ATIS with public transport information systems.
The Lyon LEADER project aims to assess the implementation, promotion, operation and validation of a coordinated strategy for traffic and transport management, incorporating ATT systems for both public and private transport based on a centralised real-time information system.
Amsterdam WEGWIJS is a planned dynamic route guidance system based on the EuroScout beacon-based concept but extended to incorporate park-and-ride, parking and public transport information. Wegwijs is based on the results of an initial feasibility study carried out within the POLIS initiative; the results of this initial work will be extended at the start of the project before defining the full scope of the Wegwijs system.
Munich COMFORT covers transport control strategy and service centres; public transport information and management; park-and-ride guidance; advanced urban traffic control; advanced regional traffic control; advanced traveller information system; commercial fleet management; and safety aspects. Field trials will be carried out for the new transport control policies, strategies and technologies in a test site in Munich. Emphasis is given to the experimental design, system implementation/ experimentation and assessment of RTI technology in a metropolitan environment.
Dublin DUBSAFE is concerned with accident data recording and identifying engineering solutions to improve safety. It specifically deals with the use of ATT technology to help improve the quality of accident data.
The MARGOT sub-project will develop strategies, methodologies, models, algorithms and assessment techniques specifically concerned with dynamic route guidance systems. The results of the research work within MARGOT will be directly used in some of the cities' field trials, particularly those relating to the integration of dynamic route guidance with urban traffic control.
LLAMD addresses the following key issues:
the integration of ATT systems in an comprehensive framework;
the development of a common systems architecture for ATT systems;
the comparative assessment of different approaches to ATIS.
It is expected that LLAMD will make significant achievements in the integration of different ATT applications. Special emphasis is given to the consideration of the ATT systems as components of integrated regional transport concepts. The adoption as far as is practical of a common system architecture and common approaches to specific applications, as defined in the common workpackages, will help to achieve progress towards a European Integrated Road Transport Environment. It is expected that the ATT systems will contribute to the improvement of traffic conditions in the cities, and that the results of the ATT field trials will provide a step towards the widespread introduction of these systems in metropolitan areas.
The possibility exists within LLAMD to create an open library of field trial data for experimental design. It is hoped that resources will be made available to achieve this potential. In particular, LLAMD offers an opportunity for a comparative assessment of different approaches towards in-vehicle information systems.
Each of the five linked field trials is intended to provide the basis for a subsequent full implementation of the ATT systems developed and tested during the project. These systems will lead to more efficient use of the transport network and are also expected to provide benefits in terms of improved safety and convenience.
Contribution to standardisation
An important part of LLAMD is the development of consistent and compatible systems in different field sites within the same pilot project, as far as is possible within the different technical approaches being evaluated within the project. LLAMD partners are active in all the main European ATT standardisation bodies and committees, and will provide direct interaction with these bodies to promote standardisation.
