Conceição, Lígia (author), Correia, Gonçalo (author), Tavares, José Pedro (author)AV subnetworks is a way to deal with automated traffic and its technological need that will likely increase during the AVs deployment period. This strategy carries many benefits, yet some inconveniences are worth to mention. One of them relies on the fact that the design of AV subnetworks is often in practice focused on mitigating congestion...journal article 2021

Demissie, Merkebe Getachew (author), Kattan, Lina (author), Phithakkitnukoon, Santi (author), Correia, Gonçalo (author), Veloso, Marco (author), Bento, Carlos (author)Recently, the traditional taxi industry has been struggling to keep its market share, especially with the emergence of new transport network companies (e.g., Uber). One of the problems with traditional taxi services is the difficulty of matching the taxi demand to its supply when there is no phone-booking or other reservation system. From...journal article 2021

Wang, Wenjing (author), Wang, Y. (author), Correia, Gonçalo (author), Chen, Y. (author)In a multimodal public transport network, transfers are inevitable. Planning and managing an efficient transfer connection is thus important and requires an understanding of the factors that influence those transfers. Existing studies on predicting passenger transfer flows have mainly used transit assignment models based on route choice,...journal article 2020
