Global emission estimation by using probe vehicles

André-Gilles Dumont

Air pollution is becoming a more and more important aspect for transportation, particularly car emission in urban area. The objective of this paper is to evaluate the global emission of a transport network based on probe car and sensor data. Probe vehicles ...

Methodology for Developing Real-time Motorway Traffic Risk Identification Models Using Individual Vehicle Data

André-Gilles Dumont, Ashish Bhaskar, Minh Hai Pham

Most of existing motorway traffic safety studies using disaggregate traffic flow data aim at developing models for identifying real-time traffic risks by comparing pre-crash and non-crash conditions. One of serious shortcomings in those studies is that non ...

Vehicle recognition from multi-spectral and LiDAR elevation data with object-oriented analysis

André-Gilles Dumont, Sofia Samoili

This research study addresses issues of transport modeling aiming to the recognition of vehicles, with perspective to generate a knowledge base for an automatic recognition of vehicles from similar type of data. Based on two datasets consisted of multi-spe ...

Optical fiber feasibility study in Accelerated Pavement Testing facility

André-Gilles Dumont, Nicolas Bueche, Patrick Rychen

The presented research has been carried out within the European project Intelligent Roads (INTRO). The major objective followed was to assess the potential of optical fiber for pavement monitoring in comparison with classical strain gauges. Thus, both meas ...

Elasto-viscoplastic modeling of flexible pavement

André-Gilles Dumont

This communication concerns analysis of the behavior of flexible pavements using an elastic-viscoplastic constitutive relation for the asphalt concrete. The numerical model takes into consideration the influence of the temperature on the behavior of the as ...

Considering weather in simulating traffic

André-Gilles Dumont, Ashish Bhaskar, Sofia Samoili, Minh Hai Pham

The impact of weather on traffic and its behavior is not well studied in literature primarily due to lack of integrated traffic and weather data. Weather can significant effect the traffic and traffic management measures developed for fine weather might no ...

Predictive method for evaluation of pavement rutting

André-Gilles Dumont, Mehdi Ould Henia

Pavement rutting not only decreases the road service life but also creates a danger for the security of road users. In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. It is well known that the in ...

Micro-simulation Modeling of Coordination of Automated Guided Vehicles at Intersection

Denis Gillet, André-Gilles Dumont, Minh Hai Pham, Laleh Makarem

One of the challenges with autonomous vehicles is their performance at intersections. An alternative control method for the coordination of autonomous vehicles at intersections is shown. The proposed approach was grounded in multiple-robot coordination and ...

Estimation of travel time on urban networks with midlink sources and sinks

André-Gilles Dumont, Ashish Bhaskar

This paper presents a methodology for estimation of average travel time on signalized urban networks by integrating cumulative plots and probe data. This integration aims to reduce the relative deviations in the cumulative plots due to midlink sources and ...

Exploring the use of DTA for origin-destination matrix estimation

André-Gilles Dumont

Traffic simulation is more and more widely used and a helpful decision tool for planer and managers. Several tools exist and could be grouped in two main families: Macrosimulators with aggregate vision of the traffic in the network and microsimulators whic ...

Thermomechanical characterisation of asphalt pavements in laboratory conditions

André-Gilles Dumont

Due to the viscoelastic properties of bituminous concrete, temperature changes result in significant mechanical effects. This paper proposes a method to assess, first, the intrinsic thermophysical parameters (thermal conductivity and heat capacity) of a bi ...

Methodology for Travel Time Estimation on a Signalised Arterial

André-Gilles Dumont, Ashish Bhaskar

This paper presents the development and testing of a methodology for estimation of average travel time on signalised urban networks. The methodology considers the classical analytical procedure, where average travel time on a study link is estimated as the ...

Study of vehicle noise for different operating conditions

André-Gilles Dumont, Ashish Bhaskar

The noise emission level from a vehicle is significantly influenced by different driving conditions and drivers’ behaviour. Almost all the in practice road traffic noise estimation models do not differentiate between different operating conditions. In this ...

Effects of hard shoulder lanes configuration on driver’s behaviour

Jade Chapoton, André-Gilles Dumont

Nowadays, reassignments of hard shoulders into traffic lanes are spreading across Europe. This traffic management measure allows to respond to the growing saturation of high-capacity roads.In Switzerland, the first stretch to be equipped in such a way was ...

Modeling of rutting in asphalt flexible pavement

André-Gilles Dumont

This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...

Realistic laboratory curing of bituminous mixtures

André-Gilles Dumont, Michel Pittet, Marc-Antoine Fénart

In order to perform some specific testing, road laboratories apply a preliminary thermal treatment that impacts the asphalt mixture mechanical and intrinsic properties. The current standardisation in Switzerland and in Europe does not sufficiently describe ...

Decision aid model for asphalt mixture choice

André-Gilles Dumont, Nicolas Bueche

Warm Mix Asphalt (WMA) represents widely used alternative to hot mix asphalt (HMA), this in order to decrease the energy consumption and environmental load. Numerous WMA products can be found and the choice of the most favourable mixture is not necessarily ...

Applicability of road safety indicators to assess driving risks under Swiss road conditions

André-Gilles Dumont, Minh Hai Pham

Road traffic crash is a problem in every country. According to World Health Organization, in Europe there are about 127,000 people killed and at least some 2.4 million injured each year. Incident detection algorithms to detect incidents on motorways are we ...

Evaluation of Traffic Management Measures on Road Traffic Noise

André-Gilles Dumont, Ashish Bhaskar

Road traffic noise affects the quality of life in the areas adjoining the road. The effect of traffic noise on people is wide ranging and may include sleep disturbance and negative impact on work efficiency. To address the problem of traffic noise, it is n ...
