This research project ended in December 2001.
This project is conclude with MACQ Electronique.
Its consist of a collaboration between TRG and Service de Mathématique de la Gestion (SMG), ULB.
The project starts the 1st of September 2000 for two years.
It contains three parts : a method of localisation of count supplies, a method of signal phases optimization and interactions between the TRG simulator PACSIM and a dynamic signal phases manager.

This research project ended in February 2000.
This study financed by the Walloon Ministry of Equipment and Transportation (General Direction of Roads, Direction of Roads of Namur) represented an assessed traffic study regarding various scenario of road developments as defined in the circulation plan proposed by the Transitec company.
The studies had to define, beside the effects of modal transfer, dissuasion car parks and access controls, the impact of development on the volume of traffic with private vehicles and consequently on the developments capacities to receive the estimated traffic. The important modifications to the railway station site had to be taken into account namely the setting up of the MET offices and the possible creation of cinema on the station paving stone.
This project was financed by the Belgian Prime Minister Services, the Federal Office for Scientific, Technical and Cultural Affairs (OSTC). It was realized in collaboration with the Walloon Institute (Namur).
The aim was to study the feasibility for coupling a traffic simulation model with a pollutant emission simulation model, to realize such a coupling and to apply it to a test area.

This project was funded by the Department for Transport, Local government and the Regions (DTLR), London, UK. This project finished at May 1rst 2000. Web uk
The proposed work aimed at extending the functionalities of the Web-site server of travel survey data developed in the framework of the TEST project (funded by DGVII of the EU) to suit the needs of the DTLR in terms of data processing and distribution.
This research project is sponsored by the European Commission. It is part of the 4th Framework Programme (DG VII - Transport).
HIPERTRANS is a project bringing several european research groups together :
HIPERTRANS aims at designing a model allowing simulation and urban traffic forecasting faster than in real time. This simulator will be equipped with graphical interface and will be implemented in a high performance computer environment (e.g. a workstations cluster).
The TRG has a double mission: on the one hand, we have to study which model(s) could be appropriate for this simulation, and, on the other hand, we investigate a model allowing dynamic estimation of the demand.
The aim of this project was to bring a support to the Administration in the creation of a traffic model for the Walloon Region. This support included methodological developments, the development of a graphic interface, developments or adaptations of simulation softwares, as well as the application of these softwares to the regional road network in order to define the route time matrix and the calculation of vehicles flows on the different arcs.

This project was realised in collaboration with the Service de Mathématiques de la Gestion (University of Bruxelles) and S.A. Stratec (Bruxelles).
The idea is to combine the Park & Ride with a demand-responsive urban shuttles system. The potential user of such a system is the motorist who wishes to go to a town-center for which the private transport accessibility is - spontaneously or intentionally - restricted.
The system to be created should offer the user the following services :
The system is intended to be implemented in the so-called cities of middle importance, which population is comprised between 50.000 and 500.000 inhabitants.

The goal of these studies was to develop a models and methodologies system for the simulation, planning and evaluation of policies for the urban demand management.
Several measures with an innovative aspect, allowing a better management of the demand, have been tested on several european sites. Their efficiency have been evaluated with the help of some appropriate traffic models and methodologies.
Parsing travel diary results
Correcting data coming from Travel Surveys is a crucial phase of their process, but it is often long and expensive when done in a "case by case" way. The goal of this project was to implement automatic data correction methods to speed up the process and make it more reliable.
A WWW-Interface to travel diary results
Creation of a web site for the consultation of data from transportation surveys, and for the formulation of requests such as counts, cross-tables with or without filters, basic statistics, etc. The results are delivered on-line by CGI.

The objective of the ITEM (Integration of Traffic and Economic Models) consortium is to merge economic pricing models and traffic models (network models) in order to improve the assessment of urban transport and environment policy reforms.
Economic models of urban transport markets concentrate on total travel demand per mode, and evaluate policies in terms of welfare (including the costs of congestion, environmental pollution, accidents and noise). Traffic models emphasise the influence of characteristics of the road network on traffic flows. The combination of economic models and traffic models in a unified methodology will allow detailed analysis of a wide range of new urban transport policies.
The ITEM model is constructed on the basis of two existing models: the TRENEN II URBAN model (available at CES) which is an economic pricing model, and the ATES model (available at GRT) which is a typical network model. The two models are merged by adapting the network structure of ATES to a level of aggregation suitable for the integration, and by making the equilibrium and cost definitions of both models congruent. The merger will be either complete, or will take place via automated model interaction. This requires intensive interdisciplinary research work between economists and mathematicians.
Some dimensions of the models are extended : a better representation of the economics of public transportation, of the implementation costs of road pricing, the presence of different income groups, and the translation of external accident, environment and congestion costs to the level of each link.
The new model is used to test the introduction of new urban transport policies (road pricing) in two case studies : Namur and probably Antwerp. For each of these two cases, a network model is merged with an economic pricing model to test the effects of alternative road pricing schemes and other urban transport policies (pedestrian areas, etc.).
The purpose of this study is to determinate the most common sociological and mechanical causes of road body accidents in order to take the most efficient policy measures.
An accident is generally the result of several factors.
For instance :
Each group of factors, sociological and mechanical, defines a kind of accident. It is the about defining the most frequent types of accidents to know the mechanical reasons and the targets, which will enable to define the strategies as regards to the road safety.
This contract has been notified by the Wallon Region on April, 12th, and covers a period of eight months.
This research aims to establish a mathematical and computer car following model, for vehicles on one, two or three lanes. The final goal is to detect accident conditions.
Car following models are designed to describe how one vehicle follows another. A better understanding of the way drivers follow them, at a microscopic level, is necessary for a better knowledge of the mechanisms involved in accidents, particularly chain collisions.
The model will have to incorporate differences of behaviour between drivers and different vehicles (lorries and light vehicles), with appropriate parameters.
The study is realized in collaboration with the Minister of Equipment and Transport (MET), which have to collect data. The University is responsible of the model calibration and validation. Some other obectives are pursued. The model will have to be used to study flow-speed and gap-speed curves, and the analysis of platoon driving, under the control of a policeman on a motorbike. Another goal is to establish road capacities.
