Towards sustainable transport in developing countries: Preliminary findings on ...
Hasselwander, Marc; Bigotte, João F.; Antunes, António P.; Sigua, Ricardo G.Mobility as a Service (MaaS) is a recent concept that is gaining momentum in both the scientific world and the private sector. First studies and field trials – essentially conducted in developed countries – suggest that MaaS can influence people's mobility behavior and create more efficient and sustainable transport systems for the future. We intend to contribute to the existing knowledge about MaaS by extendin...
A Cellular Automata Model for Integrated Simulation of Land Use and Transport I...
Pinto, Nuno; Antunes, António P.; Roca, JosepCellular automata (CA) models have been used in urban studies for dealing with land use change. Transport and accessibility are arguably the main drivers of urban change and have a direct influence on land use. Land use and transport interaction models deal with the complexity of this relationship using many different approaches. CA models incorporate these drivers, but usually consider transport (and accessibi...
Regional Wastewater System Planning under Population Dynamics Uncertainty
Zeferino, João A.; Antunes, António P.; Cunha, Maria C.The authors acknowledge the publisher in granting permission for making post-print version available in open access institutional repository.; Regional wastewater systems are used for the collection and treatment of the wastewater generated in a region and aimed at guaranteeing surface water quality. The volumes of wastewater to process depend on future population and thus are affected by the uncertainty inhere...
Planning regional wastewater systems across borders
Zeferino, João A.; Cunha, Maria C.; Antunes, António P.The authors acknowledge the publisher in granting permission for making post-print version available in open access institutional repository.; Regional wastewater systems are aimed at guaranteeing surface water quality by properly collecting and treating the wastewater generated in the population centers of a region. But the most suitable planning regions are often divided by political or social boundaries and ...
Interurban road network planning model with accessibility and robustness object...
Santos, Bruno F.; Antunes, António P.; Miller, Eric J.Road network planning (or design) problems consist of determining the best investment decisions to be made with regard to the improvement of a road network. In this paper, we propose an optimization model for long-term interurban road network planning where accessibility and robustness objectives are simultaneously taken into account. Three network robustness measures were defined to assess different robustness...
A hierarchical location model for public facility planning
Teixeira, João C.; Antunes, António P.In this article, we present a discrete hierarchical location model for public facility planning. The main features of the model are: an accessibility maximization objective; several levels of demand and of facilities; a nested hierarchy of facilities (i.e. a facility of a given level can serve demand of equal and lower levels); maximum and minimum capacity constraints; and user-to-facility assignment constraint...
