Area-based equitable pricing strategies for multimodal urban networks with heterogeneous users

Equity issues among travellers are critical in congestion pricing. Failure to treat equity can lead to low acceptability towards pricing. In this paper, we develop congestion pricing schemes to improve both equity and traffic performance, for multimodal ne ...

Linking trajectory data collected with a swarm of drones to the underlying urban network for macroscopic traffic parameter estimation

Nikolaos Geroliminis, Emmanouil Barmpounakis

Recently, an open-data initiative was announced with one of the most complete datasets to study urban congestion. The pNEUMA dataset consists of more than half a million trajectories in heterogeneous traffic. In order to utilize the dataset for macroscopic ...

Toward Sustainable Ridesourcing Services: A Simulation Study on the Effects of Congestion, Fleet Size, and Willingness to Share

Nikolaos Geroliminis, Caio Vitor Beojone

Human mobility in large cities is a complex dynamical system with high density of population, many transport modes to compete for limited available space and many operators that try to efficiently manage different parts of this system. New emerging modes o ...

A Decentralized Adaptive Model-Based Real-time Control for Active Distribution Networks Using Battery Energy Storage Systems

Sidi-Rachid Cherkaoui, Mario Paolone, Maryam Bahramipanah, Dimitri Torregrossa

This paper proposes a real-time decentralized control algorithm in multi-area active distribution network relying only on dispersed Battery Energy Storage Systems (BESSs). In particular, we propose a zonal control strategy targeting voltage support and lin ...

Time-dependent area-based pricing for multimodal systems with heterogeneous users in an agent-based environment

Guillaume Rérat, Nikolaos Geroliminis, Nan Zheng

In this paper, we investigate an area-based pricing scheme for congested multimodal urban networks with the consideration of user heterogeneity. We propose a time-dependent pricing scheme where the tolls are iteratively adjusted through a Proportional-Inte ...

Advanced Control of Active Distribution Networks Integrating Dispersed Energy Storage Systems

Maryam Bahramipanah

Due to the increased penetration of Distributed Generations (DGs) in distribution networks, the system control and operation may become quite different from the case of traditional network. Most DGs can only provide intermittent power to the Active Distrib ...

A Dynamic Network Approach for Multimodal Urban Mobility : Modeling, Pricing and Control

Nan Zheng

Recent advances in traffic flow theory at the network level, namely the Macroscopic Fundamental Diagram (MFD), reveals the existence of well-defined laws of congestion dynamics at aggregated levels. The same knowledge for multimodal networks however is lim ...

Estimation of the network capacity for multimodal urban systems

Burak Boyaci, Nikolaos Geroliminis

As more people through different modes compete for the limited urban space that is set aside to serve transport, there is an increasing need to understand details of how this space is used and how it can be managed to improve accessibility for everyone. Ul ...
