Knowledge-Assisted Visualization of Multi-Level Origin-Destination Flows Using Ontologies

March 1, 2021Posted inPublications
Origin-destination matrices help understand the movement of people within cities. Recently, we published a research work that built upon the premise that different stakeholders need to analyze mobility flows from spatio-temporal perspectives that are appropriate to their context of analysis. Herein we report our findings on building the semantic foundation of knowledge-assisted visualization tools for analyzing OD matrices from multiple…

A multi-objective approach for DRT service using tabu search

February 19, 2021Posted inPublications
Nowadays elderly population accounted, in some countries, by more than 20% of the population, and such value tends to increase. In urban congested areas, this is a challenge to public transport systems, as elderly people may have sensory, cognitive or motor impairments that may require new types of services, such as Demand Responsive Transport (DRT). In our work, we explored…

Accessibility as an indicator to estimate social exclusion in public transport

February 12, 2021Posted inPublications
Accessibility is one of the key measures of urban transportation planning. However, this measure is usually quantified in a rather standardized way. In order to make it more flexible and robust, we used the concept of the 6-minute walking distance (6MWD) to measure accurately the walking ability for different groups of the population. The proposed tool was applied to the…
