Literature review into traffic models that can be used to model dynamic exposure to air pollution Hasselt University

The aim of this project is to carry out a literature review to determine the most optimal traffic model that can be used for modelling personal exposure to air pollution in Flanders. The literature review will consider a broad range of methods that map the mobility of (a representative part of) of the population.This includes new technologies that can map time-activity patterns and visited locations of large groups of people. The literature ...

Improving the Accuracy and Efficiency of Demand Calibration for Dynamic Traffic Models KU Leuven

Chris Tampère

Centre for Industrial Management / Traffic & Infrastructure, Division of Geography and Tourism

Dynamic traffic assignment models involve hundreds of unknown parameters and consume considerable time for computation. Besides, the calibration process, which tries to calibrate demand (and supply) parameters to match the simulation output with real observations, is both methodologically and computationally challenging. Considering availability of the input data and field observations, the core of the OD (Origin-Destination) estimation is ...

Node models for macroscopic traffic simulation KU Leuven

Lambertus Immers

Centre for Industrial Management / Traffic & Infrastructure

Traffic signals and queues at intersections are major components of public transportation (transit) delay. Active transit signal priority (TSP) strategies are used as an effective way of reducing that delay. They can be divided in green split adjustment and phase resequencing measures. However, the effectiveness of TSP strategies is dependent on the traffic conditions, the frequency of priority requests, and their specific impact on the ...

Methods and tools for supporting the use, calibration and validation of traffic simulation models Hasselt University

A COST action is an network centered around natonally funded research projects in fields that are of interest to at least five COST countries. The main objective of this Action is to develop, implement and promote the use of methods and procedures for supporting the use of traffic simulation models, especially on the topics of model calibration and validation.To this date, the bulk of resources and effort in the field of traffic simulation have ...

Development of mathematical pilot models for fast-time ship manoeuvring simulation and traffic planning for harbour approach channels Ghent University

Marc Vantorre

Department of Civil engineering

Ship manoeuvring simulation is widely applied when designing new navigation areas and for assessing channel safety. The research project uses intelligent control algorithms to develop a novel mathematical pilot model for fast-time manoeuvring simulations in complex situations and for shipping traffic planning. The results will be applied to selected cases in Flemish harbours and channels and in Chinese navigation areas.

Methods for estimating the Belgian traffic abroad and foreign traffic in Belgium "MEBETA" Hasselt University

Davy JANSSENS

Transportation Behaviour, Transportation Research Institute, Data-analysis and Modelling

The objective of this project is to develop a methodology that allows to make an estimation of the Belgian traffic abroad and foreign traffic in Belgium. The results should apply to any type of vehicle (cars, trucks, ..). In addition, the developed methodology is also applied to determine the statistics of the last three years (2005,2006 and 2007). The first part of the project will study how other countries address these issues. The study of ...

Numerical Prediction of Ground Vibrations Generated by Road Traffic and Pavement Breaking KU Leuven

Geert Degrande

Structural Mechanics Section

Poor ride quality and traffic induced noise and vibrations require replacement or rehabilitation of deteriorated pavements. In the case of concrete roads, the pavement is usually broken to prepare it for removal or as the first step in the cracking and seating method of road rehabilitation. The pavement breaking operation generates a high level of ground-borne vibrations. In this study, three aspects of vibrations in the vicinity of concrete ...

A model-based approach for evaluating the safety and environmental effects of traffic policy measures Hasselt University

Tom BELLEMANS

Transportation Behaviour, Business Informatics, Data-analysis and Modelling

The principal objective of this research project concerns the development of a framework for the evaluation of traffic policy measures on road safety, the environment and human health. This framework will develop and integrate different submodels, e.g. an activity-based transportation model, an agent-based traffic assignment model, and an emission, dispersion and exposure model, into one overall model framework. The valorisation of the ...

Transport has a significant impact on environment and human health, be it through air pollution, noise, traffic safety or the impact on physical activity. Health impact assessments can quantify the health burden of these transport related health risks and have proven their relevance for national and international standard setting. The current research assesses the health impact of air pollution and traffic safety in Flanders and Brussels, using ...
