Framework for real-time traffic forecasting methodology under exogenous parameters

André-Gilles Dumont, Sofia Samoili

Ensuing from the deteriorating conditions of road networks, traffic forecasting techniques with mathematical and computer-theory methods have been employed to address the real-time prediction of traffic conditions and their dynamic control, with the optimu ...

A Dynamic Cordon Pricing Scheme combining a Macroscopic and an Agent-based traffic Models

Nikolaos Geroliminis, Nan Zheng

Pricing is considered an effective management policy to reduce traffic congestion in transportation networks. In this paper we combine a macroscopic model of traffic congestion in urban networks with an agent-based simulator to study congestion pricing sch ...

Decentralized method for traffic monitoring

Guillaume Adrien Sartoretti, Bastien Chopard

We propose a decentralized method for traffic monitoring, fully distributed over the vehicles. An algorithm is provided, specifying which information should be tracked to reconstruct an instantaneous map of traffic flow. We test the accuracy of our method ...

Demand-oriented traffic management for incidents and disasters.

Traffic simulation has been extensively used as a decision support tool for efficient traffic management in daily life. During disasters and incidents, traffic simulation can further help rescue teams to understand the current traffic state and the possibl ...

Exploiting the fundamental diagram of urban networks for feedback-based gating

Anastasios Kouvelas, Mehdi Keyvan Ekbatani

Traffic signal control for urban road networks has been an area of intensive research efforts for several decades, and various algorithms and tools have been developed and implemented to increase the network traffic flow efficiency. Despite the continuous ...

Calibration of bus parameters in microsimulation traffic modelling

Microscopic traffic simulation models have advanced significantly in recent years and are now used extensively around the world for detailed traffic modelling where dynamic operations have to be represented. Whilst extremely powerful, these models can have ...

Considering weather in simulating traffic

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

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 ...

Motorway Traffic Risks Identification Model - MyTRIM Methodology and Application

Minh Hai Pham

Road traffic crashes are becoming increasing concerns in many countries. In Europe, many efforts have been devoted to improve road traffic safety yet the important target of halving the number of yearly road deaths in 2010 could not be achieved in many Eur ...

An Empirical Analysis on the Arterial Fundamental Diagram

Nikolaos Geroliminis

For uninterrupted traffic flow, it is well-known that the fundamental diagram (FD) describes the relationship between traffic flow and density under steady state. For interrupted traffic flow on a signalized road, it has been recognized that the arterial f ...

Real-time Traffic Prediction Under Exogenous Factors

Sofia Samoili

Traffic congestion is an escalating phenomenon with multidimensional impact. The proposed research stands in the hypothesis that a traffic forecasting method, acknowledging several exogenous parameters for a more plausible representation of traffic evoluti ...
