Hybrid Modeling and Predictive Control of Bus Transport Systems

Nikolaos Geroliminis, Isik Ilber Sirmatel

Bus operations, due to their unstable nature, are inefficient when left to their own devices. Irregularities such as bus bunching lead to loss of time and decrease bus service quality. Development of bus transport system management schemes to avoid bus bun ...

Multiple Concentric Gating Traffic Control in Large-Scale Urban Networks

Nikolaos Geroliminis, Mehmet Yildirimoglu

A new gating strategy for concentric cities based on the notion of the macroscopic or network fundamental diagram and the feedback-based gating concept is introduced and successfully tested. Different regions of large-scale urban networks may experience co ...

Equilibrium analysis and route guidance in large-scale networks with MFD dynamics

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei, Mehmet Yildirimoglu

Recent studies have demonstrated that Macroscopic Fundamental Diagram (MFD), which provides. an aggregated model of urban traffic dynamics linking network production and density, offers a new generation of real-time traffic management strategies to improve ...

Economic Model Predictive Control of Large-Scale Urban Road Networks via Perimeter Control and Regional Route Guidance

Nikolaos Geroliminis, Isik Ilber Sirmatel

Local traffic control schemes fall short of achieving coordination with other parts of the urban road network, whereas a centralized controller based on the detailed traffic models would suffer from excessive computational burden. State estimation for deta ...

Dynamic clustering and propagation of congestion in heterogeneously congested urban traffic networks

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

The problem of clustering in urban traffic networks has been mainly studied in static framework by considering traffic conditions at a given time. Nevertheless, it is important to underline that traffic is a strongly time-variant process and it needs to be ...

Traffic congestion and noise emissions with detailed vehicle trajectories from UAVs

Nikolaos Geroliminis, Emmanouil Barmpounakis, Jasso Espadaler Clapés

Excessive noise in cities due to road traffic negatively affects human health. We utilize detailed vehicle trajectories collected by a swarm of drones to estimate traffic noise emissions in an urban environment. We use the CNOSSOS model to estimate vehicle ...

Model Predictive Perimeter Control for Urban Areas with Macroscopic Fundamental Diagrams

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 different network regions a unimodal, low-scatter relationship between network vehicle density and network space-mean flow. In t ...

City size, network structure and traffic congestion

Nikolaos Geroliminis

This paper presents an alternative approach for analyzing the relationship between land use and traffic congestion by employing the Macroscopic Fundamental Diagram (MFD). The MFD is an empirically observed relationship between traffic flow and traffic dens ...

A macroscopic modelling framework for the dynamic pricing of pool ride-splitting vehicles in bus lanes

Nikolaos Geroliminis, Nils Gustav Nilsson, Lynn Fayed

The impact of ride-hailing vehicles on congestion raises multiple concerns, particularly in areas where the network space is constrained and the route infrastructure is unevenly distributed among multi-modal users. Mainly, idle ride-hailing vehicles pose m ...

A Linear-Parameter-Varying Formulation for Model Predictive Perimeter Control in Multi-Region MFD Urban Networks

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

An alternative approach for real-time network-wide traffic control in cities that has recently gained attention is perimeter flow control. Many studies have shown that this method is more efficient than state-of-the-art adaptive signal control strategies f ...

A hybrid hypercube - genetic algorithm approach for deploying many emergency response mobile units in an urban network

Nikolaos Geroliminis

Emergency response services are critical for modern societies. This paper presents a model and a heuristic solution for the optimal deployment of many emergency response units in an urban transportation network and an application for transit mobile repair ...

On the new era of urban traffic monitoring with massive drone data: The pNEUMA large-scale field experiment

Nikolaos Geroliminis, Emmanouil Barmpounakis

The new era of sharing information and "big data" has raised our expectations to make mobility more predictable and controllable through a better utilization of data and existing resources. The realization of these opportunities requires going beyond the e ...

A systematic analysis of multimodal transport systems with road space distribution and responsive bus service

Nikolaos Geroliminis, Nan Zheng

A smart design of transport systems involves efficient use and allocation of the limited urban road capacity in the multimodal environment. This paper intends to understand the system-wide effect of dividing the road space to the private and public transpo ...

Monotonicity in the trip scheduling problem

Nikolaos Geroliminis, Raphael Ali Francis Lamotte

The equilibrium of the archetypal morning commute problem with alpha -,B - gamma preferences has been shown to be unstable with various rational adjustment mechanisms, under both continuous and discrete day-to-day dynamics. It is not clear however whether ...

A dynamic macroscopic framework for pricing of ride-hailing services with an optional bus lane access for pool vehicles

Nikolaos Geroliminis, Nils Gustav Nilsson, Lynn Fayed

On-demand trip sharing is an efficient solution to mitigate the negative externalities e-hailing has on traffic in a network. It motivates platform operators to reduce their fleet size and serves the same demand level with a lower effective distance travel ...

Estimation of regional trip length distributions for the calibration of the aggregated network traffic models

Nikolaos Geroliminis

The calibration of trip lengths is an important challenge for multi-regional MFD-based applications, as it can influence the dynamics of regional densities (and speeds). Existing research has not paid significant attention in the topic, giving opportunitie ...

How different charging prices can contribute to the balancing of ride-hailing services with electric vehicles

Nikolaos Geroliminis, Nils Gustav Nilsson, Marko Maljkovic

Motivated by the growing popularity of both the services offered by the ride-hailing companies and the electric vehicles (EVs), we study a scenario in which a central body e.g., the government, wants to influence how the EVs of different ride-hailing compa ...
