Technical Abstract

This deliverable D06.2 is a result of Work Package WP06 of the DACCORD project. Work Package WP06 has as title: Co-ordinated Control for Dynamic Traffic Management Systems. The objective of this Work Package concerning this deliverable is to present a couple of software tools that were developed in the DACCORD framework . This Deliverable includes the software itself and explanations on its use.

This document describes the use of the control software tools:

Advanced Motorway Optimal Control (AMOC). AMOC is a co-ordinated and integrated motorway control software tool. It derives control strategies based on the macroscopic traffic flow modelling tool METANET and on a nonlinear optimisation technique. It can consider route guidance and/or ramp metering and/or motorway-to-motorway control measures for motorway networks of arbitrary topology. For each of the control measures considered optimal control trajectories over time are determined.

Decision Support System –Demo CTMS. The CTMS-demo on the CD-Rom gives an insight view on the look and feel of the CTMS co-ordination system. It's the front-end of the real-system and allows to 'play' with all functionalities like setting parameters, viewing the actual value of variables, dealing with fault monitoring and reports, configuring the system with calendar functions, different user types, etc.

For each one of these software tools explanations regarding their use are presented in the corresponding annexes.

This document is the deliverable D06.2 of the Transport Telematics project DACCORD (Development and Application of Co-ordinated Control of Corridors). The DACCORD project aims to design, implement and validate a practical Dynamic Traffic Management System for integrated and co-ordinated control of inter-urban corridors.

This document reports on part of the work performed within Work Package WP06, Co-ordinated Control for Dynamic Traffic Management Systems.

In the DACCORD framework, the term co-ordinated control refers to the co-operation of the same kind of motorway control measures towards a common objective, while the term integrated control refers to the co-operation of different kinds of motorway control measures towards a common objective.

The objectives of WP06, according to Technical Annex 1, is to develop generic, co-ordinated control tools for periurban traffic networks including a number of different control measures (ramp metering, motorway-to-motorway control, VMS, VDS, route guidance), and to apply them to the DACCORD sites.

The work in Work Package WP06 is reflected in three deliverables:

Deliverable D06.1 : Co-ordinated control strategies.
Deliverable D06.2 : Co-ordinated control software.
Deliverable D06.3 : Off-line simulation results.

The objective of this deliverable D06.2 is to report on a couple of control software tools developed that are used for the determination of control strategies that are implemented (or will be implemented) in the DACCORD sites.

The use of the above mentioned software is presented in detail in the corresponding annexes attached at the end of this document. The contents of the annexes are as follows.

In Annex A the guidelines for the operation of the AMOC control software tool are given in terms of the required input files. The format of these files is presented, and each particular entry is explained. A detailed example is also included in order to help the reader understand how these input files are constructed. The macroscopic traffic model used by AMOC was described in detail in Annex A of the Deliverable D06.1, and the algorithm used in Annex C of the same document. Detailed off-line simulation results obtained from AMOC can be found in Annex F of Deliverable D06.3.

Annex B contains a description on the use of the Decision Support System – Demo CTMS. A short historical background is provided followed by a description of its hierarchical structure. Finally instructions on its installation and its use are provided. Parts of the specifications of the applications on the CD-ROM were explained in Annex I of the Deliverable D06.1. The information on the CD-ROM is self-contained and the written information in this document is intended to help the user of the CTMS-demo in his/her first steps.
