Analyzing fluctuations in car-following

Many car-following models predict a stable car-following behavior with a very small fluctuation around an equilibrium value g∗ of the net headway g with zero speed-difference Δv between the following and the lead vehicle. However, it is well-known and addi ...

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 ...

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 ...

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 ...

Modelling incidents for dynamic bus fleet management purposes: a UK perspective

Bus operations throughout the world are increasingly being equipped with Intelligent Transport Systems such as Automatic Vehicle Location (AVL). AVL can support a variety of functions, including Dynamic Bus Fleet Management (DBFM), which has yet to be esta ...

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 ...

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 ...

Design of Optimal Traffic Flow Control at Intersection with Regard for Queue Length Constraints

Jack Haddad

Consideration was given to a well-known problem of traffic control at an individual intersection with minimal total delay. The constraints on control (duration of green light in the main direction) and phase variables (queue lengths along each direction) w ...

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 ...

Traffic Effects of the Emergency Lane Use

Sofia Samoili

The use of the hard shoulder/emergency lane (EL) is analysed in the current research, with case study the first experimental application of emergency lane use undertaken in Switzerland (Morges - Écublens). The EL is activated during peak hours and when con ...
