Meeting #9 – City logistics – an introductory overview of urban freight distribution [Part 2/2]

GITMob meeting no. 9

This session took place on 9 May 2019 at room L202A of Faculdade de Engenharia da Universidade do Porto (FEUP). The topic of the session was City logistics – an introductory overview of urban freight distribution, presented by Bruno Oliveira ORCID iD, a Ph.D. student of the Doctoral Program in Transportation Systems of FEUP.

 

Abstract

City logistics plays an important role in creating efficient, environmentally friendly, and safe urban freight transport. Several logistics measures have been proposed to address the negative externalities of urban freight distribution. We present a brief overview of these measures, with a particular focus on the logistics and transport organization of urban distribution systems.

Meeting #8 – The impact of dedicated roads for automated vehicles in urban transport networks

 

GITMob meeting no. 8

This session took place on 2 May 2019 at room L202A of Faculdade de Engenharia da Universidade do Porto (FEUP). The topic of the session was The impact of dedicated roads for automated vehicles in urban transport networks, presented by Lígia Conceição ORCID iD, a Ph.D. student of the Doctoral Program in Transportation Systems of FEUP.

 

Abstract

This research is focused on a complex transport planning problem of designing a road network for the deployment of AVs, where the network comprises links for mixed traffic and links for the exclusive use of automated traffic. A non-linear programming model evaluates the benefits of having dedicated infrastructure for AVs and the associated costs from CVs detour. Strategies are analyzed in the long-term. My case study is the city of Delft in the Netherlands. Dedicated roads for AVs are a beneficial strategy at system-level, reducing the overall generalized costs and the average congestion. However, AVs associated comfort might result in more CVs trips and extra queueing in the surroundings of AVs zones.

Meeting #28 – The impact of reversible lanes in the main freeway (VCI) of Porto city

 

GITMob meeting no. 28
This session will take place online on 23 July 2020 (no registration required: Zoom Link). The topic of this session will be The impact of reversible lanes in the main freeway (VCI) of Porto city, presented by Lígia Conceição ORCID iD, Ph.D. in Transportation Systems. This presentation focuses on her research work.

 

Abstract
In real-world cities, solving Road Network Design Problems (RNDP) in a single-level framework through optimization is not advisable, given the numerical complexity that turns the process very time-consuming. Simulation methods appear as a method to reduce the complexity of the mathematical problem by solving one part of the problem: the lower-level problem, i.e., the performance of the network for a given network design solution. Joining simulation and optimization is also challenging in terms of programming, software interfaces, and time resources, yet a feasible solution can be obtained even when the solution process does not reach the end. The main objective of this presentation is to present the first results of a simulation-optimization (SO) framework of reversible lanes (a smart traffic control system) applied to a particular case-study: the main freeway (also known as VCI) of the city of Porto, in Portugal.

Meeting #26 – Ontologies for semantic integration of public transportation data: a gentle introduction [Webinar, Part 2/2]

 

GITMob meeting no. 26
This webinar was presented by Thiago Sobral ORCID iD, a researcher with the Instituto de Engenharia de Sistemas e Computadores, Tecnologia e Ciência (INESC TEC), and Invited Assistant Professor at the University of Porto, Faculty of Engineering. This presentation stems from his recently published work available here. Link: Zoom meeting.

 

Abstract
In the first session, we provided a gentle introduction to ontology and discussed the different types of ontologies and their building blocks, and their importance for providing semantics to heterogeneous data. In this next session we will provide some real examples related to public transportation data, which can present different types of data heterogeneity and conform to distinct standards. We will present some practical tools that can be used to model ontologies and integrate them with actual data using graph databases.

Abstract

In this session we will introduce and define the different types of ontologies, and their importance for providing semantics to heterogeneous data retrieved from multiple sources. The examples discussed throughout this session will be related to public transportation data, which can present different types of data heterogeneity and conform to distinct standards. We will present some practical tools that can be used to model ontologies and integrate them with actual data using graph databases.

Meeting #24 – As cidades e a mobilidade do futuro [Mesa Redonda Online]

GITMob meeting no. 24

Moderador: Sérgio Pedro Duarte

Há cerca de dois meses as nossas rotinas mudaram e as cidades pararam. Muitos ficaram a trabalhar em casa, as ruas ficaram vazias e as lojas fecharam. Alguns redescobriram o comércio local, outros descobriram o comércio eletrónico. Alguns descobriram o tempo livre, outros descobriram os seus bairros percorrendo-os a pé. As ruas vazias trouxeram o silêncio e o ar mais limpo. À medida que as pessoas saíam, as crianças descobriram o que é brincar na rua.Depressa surgiu a ideia que a nossa vida mudou para sempre. A pandemia trazia consigo oportunidades para repensar a economia, o ensino, o comércio, o trabalho. O clima ia mudar, íamos possuir menos e poluir menos. Ao mesmo tempo, sentíamos a falta de socializar, de sair, de estar com pessoas. O silêncio também trazia confusão.

Agora que começamos a sair e a voltar à normalidade. Mas que normalidade é essa que vamos encontrar? O ruído? A poluição? O trânsito?
Por todo o mundo vemos exemplos de cidades que aceleraram alterações aos planos de mobilidade (Londres, Milão, Paris, etc.) para criar uma cidade mais amiga das pessoas e do ambiente. Querem menos carros e mais pessoas. Querem mais proximidade, mas os locais que eram mais frequentados querem continuar a ter quem os visite.

Conseguimos atingir esse equilíbrio? Seremos capazes de nos adaptar a essas novas cidades, ou as nossas deslocações continuarão iguais?
Não é possível pensarmos numa nova cidade sem mudarmos a forma como nos deslocamos. Qual será, então, o impacto da pandemia nas cidades e na mobilidade urbana? Vamos voltar ao normal, ou vamos repensar as cidades e a mobilidade?

O GITMob quis ouvir a perspetiva de quem estuda as cidades, de quem estuda a mobilidade, e de quem aplica as ideias na prática. No próximo dia 26 de maio (terça-feira), pelas 11h00, irá decorrer uma mesa redonda online. Para ter acesso ao endereço da reunião será necessário realizar inscrição aqui.
Aproveitando que os novos hábitos digitais nos abriram portas para ouvir pessoas que nem sempre iríamos conseguir, convidamos três oradores exteriores à FEUP para falarmos sobre o futuro das cidades e da mobilidade.

Ficamos à tua espera,
GITMob
