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 ...

Experienced Travel Time Prediction for Freeway Systems

Nikolaos Geroliminis, Mehmet Yildirimoglu

Travel time is considered as one of the most important performance measures for roadway systems, and dissemination of travel time information can help travelers to make reliable travel decisions such as route choice or time departure. Since the traffic dat ...

Evaluation of Microsimulated Traffic Light Optimisation Using V2I Technology

Within the research project KOLINE a cooperative system for urban road transport is developed. Its traffic related goals are to reduce travel time and fuel consumption as well as noise and pollutant emissions. The herein described evaluation shall determin ...

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 ...

Operational macroscopic modeling of complex urban intersections

Gunnar Flötteröd

This article describes a new approach to the macroscopic first order modeling and simulation of traffic flow in complex urban road intersections. The framework is theoretically sound, operational, and comprises a large body of models presented so far in th ...

Evolution of Cache Replacement Policies to Track Heavy-Hitter Flows

Marco Canini

Several important network applications cannot easily scale to higher data rates without requiring focusing just on the large traffic flows. Recent works have discussed algorithmic solutions that trade-off accuracy to gain efficiency for filtering and track ...

Optimal mainstream traffic flow control of large-scale motorway networks

The continuously increasing daily traffic congestions on motorway networks around the world call for innovative control measures that would drastically improve the current traffic conditions. Mainstream traffic flow control (MTFC) is proposed as a novel an ...

Dynamic speed limit control to resolve shock waves on freeways : Field test results of the SPECIALIST algorithm

We present the real-world test of the SPECIALIST algorithm in which dynamic speed limits were used to resolve shock waves on freeways. The real-world test was performed in the period September 2009–February 2010 on a 14 km long stretch on the Dutch A12 fre ...

The spatial variability of vehicle densities as determinant of urban network capacity

Nikolaos Geroliminis, Seyyed Amin Mazloumian

Due to the complexity of the traffic flow dynamics in urban road networks, most quantitative descriptions of city traffic so far have been based on computer simulations. This contribution pursues a macroscopic (fluid-dynamic) simulation approach, which fac ...

Lagrangian formulation of a multi-class kinematic wave model

The kinematic wave model is often used in simulation tools to describe dynamic trafﬁc ﬂow and to estimate and predict trafﬁc states. Discretization of the model is generally based on Eulerian coordinates, which are ﬁxed in space. However, the Lagrangian co ...
