Estimation of regional trip length distributions for the calibration of the aggregated network traffic models
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 opportunities for answering some fundamental questions. In this paper, we propose an original methodology ...

This work focuses on the application of so-called accumulation-based and trip-based MFD approaches to real transportation networks and discusses the calibration of the MFD shape and trip lengths estimation using a thorough validation of the network dynamics with micro-simulation data. As network state observations are often scattered close to the s...

This work focuses on the application of accumulation-based and trip-based MFD approaches to real transportation networks and discusses the calibration of the MFD shape and trip lengths estimation using a thorough validation of the network dynamics with micro-simulation data. This work not only investigates a classical unimodal approach to fit the p...
The role of trip lengths in control strategies and Macroscopic Fundamental Diagram traffic models
Since the development of the Macroscopic Fundamental Diagram (MFD), many traffic control strategies and algorigthms have been developed to implement perimeter control over a specific urban region. In most cases, the typical assumption is to have a common average trip length for all vehicles traveling within the same region. However, the proper cali...

On the calibration of time-varying trip length distributions for the aggregated traffic models
One of the key questions for Macroscopic Fundamental Diagram traffic models lies in the calibration of the trip lengths, i.e. the travel distances of vehicles in the regions. Few studies in the literature have attempted to propose methodological frameworks to calibrate the trip lengths. Batista et al. (2019) propose a framework to explicitly calcul...

Impede autonomous vehicles merging at on-ramps?
This paper sheds some light on the macroscopic and microscopic characteristic of traffic flow on freeways in the merging areas in presence of Human-Driven Vehicles (HDV) and Connected Autonomous Vehicle (CAV) by thoroughly digging into the literature, exploiting real data and simulating simple scenarios. In particular, in the first step, an extensi...
L'hydrométrie en Nouvelle-Zélande : l'esprit « Number 8 wire »
L'hydrométrie en Nouvelle-Zélande présente des enjeux, problèmes et solutions évidemment très semblables à ceux qui font le quotidien des hydromètres de tous les pays. Cependant, comme dans bien d'autres domaines, les Kiwis font face à un environnement resté très sauvage avec un esprit positif et pragmatique d'une efficacité remarquable. Les sujets...
