On the consistency of freeway macroscopic merging models

Nikolaos Geroliminis, Josep Maria Torne Santos

Many first-order macroscopic models for freeway traffic have been developed since the seminal work on the well-known Lighthill-Whitham-Richards, or LWR, continuous model. The asymmetric cell transmission model (ACTM) is a widely accepted macroscopic model ...

Empirical Observations of Congestion Propagation and Dynamic Partitioning with Probe Data for Large-Scale Systems

Jun Luo, Yuxuan Ji, Nikolaos Geroliminis

Research on congestion propagation in large urban networks has been based mainly on microsimulations of link-level traffic dynamics. However, both the unpredictability of travel behavior and the complexity of accurate physical modeling present challenges, ...

Perimeter flow control in bi-modal urban road networks: A robust feedback control approach

Nikolaos Geroliminis, Nan Zheng, Konstantinos Ampountolas

n this paper, we integrate a three-dimensional Macroscopic Fundamental Diagram (3D-MFD) modelling for mixed bi-modal urban traffic in a control framework for congested urban regions. The 3D-MFD relates the accumulation of cars and buses and the outflow (or ...

A three-dimensional macroscopic fundamental diagram for mixed bi-modal urban networks

Nikolaos Geroliminis, Nan Zheng, Konstantinos Ampountolas

Recent research has studied the existence and the properties of a macroscopic fundamental diagram (MFD) for large urban networks. The MFD should not be universally expected as high scatter or hysteresis might appear for some type of networks, like heteroge ...

On the distribution of urban road space for multimodal congested networks

Nikolaos Geroliminis, Nan Zheng

Transport systems in real cities are complex with many modes of transport sharing and competing for limited road space. This work intends to understand how space distributions for modes and interactions among modes affect network traffic performance. While ...

Prediction of vehicle activity for emissions estimation under oversaturated conditions along signalized arterials

Nikolaos Geroliminis, Eleni Christofa

The traditional methodology for estimating vehicle emissions based on vehicle miles traveled and average speed is not reliable because it does not consider the effects of congestion, control devices, and driving mode (cruise, acceleration, deceleration, an ...

Cooperative traffic control of a mixed network with two urban regions and a freeway

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei, Jack Haddad

Currently most optimization methods for urban transport networks (i) are suited for networks with simplified dynamics that are far from real-sized networks or (ii) apply decentralized control, which is not appropriate for heterogeneously loaded networks or ...

Dynamics of Lane Distribution Flows in Freeways

André-Gilles Dumont, Sofia Samoili, Nikolaos Geroliminis

Lane density and lane flow distribution are utilised in the current study as characteristics of traffic dynamics for control and planning purposes in freeways with ITS systems. As part of an on-going research, the Lane Flow Distribution Ratio (LFDR) and th ...

Feedback Perimeter Control for Multi-region Large-scale Congested Networks

Nikolaos Geroliminis

It was recently observed from empirical traffic data that by aggregating the highly scattered plots of flow versus density from individual loop detectors for city regions with homogeneous spatial distribution of congestion, the scatter significantly decrea ...

Optimal Perimeter Control for Two Urban Regions With Macroscopic Fundamental Diagrams: A Model Predictive Approach

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei, Jack Haddad

Recent analysis of empirical data from cities showed that a macroscopic fundamental diagram (MFD) of urban traffic provides for homogenous network regions a unimodal low-scatter relationship between network vehicle density and network space-mean flow. In t ...

Estimating MFDs in simple networks with route choice

Nikolaos Geroliminis

The concept of the Macroscopic Fundamental Diagram (MFD) is elegant and attractive because it provides a global view of traffic behavior and performance at a network level. However, recent research shows that the MFD shape can be influenced by local traffi ...
