Activity-based model for medium-sized cities considering external activity–travel: Enhancing FEATHERS framework Universiteit Hasselt
Travel demand modeling has evolved from the traditional four-step models to tour-based models which eventually became the basis of the advanced Activity-Based Models (ABM). The added value of the ABM over others is its ability to test various policy scenarios by considering the complete activity–travel pattern of individuals living in the region. However, the majority of the ABM restricts residents’ activities within the study area which results ...
Calibrating Activity-based Models With External OD Information: An Overview Of Different Possibilities Universiteit Hasselt
Many practitioners question the advantages of activity-based models over conventional four-step models in terms of replication of traffic counts. Therefore, in this paper, a framework is highlighted that actively links travel demand models in general, and activity-based models in particular, with traffic counts. Two approaches are presented that calibrate activity-based models with traffic counts, namely an indirect and a direct approach. The ...

Modeling framework for incorporating external trips in activity-based travel demand models Universiteit Hasselt
Special issue on ambient systems, networks and technologies Universiteit Hasselt
attracted a good number of scientific papers that contributed to the state-of-the-art in the areas of these conferences' themes. All the papers selected for this special issue have been extended from their original versions and underwent two rounds of rigorous peer-review process. Based on the reviewers' feedback , as well as the evaluations of the Guest Co-editors, 21 papers were selected for this special issue from 35 invited submissions. The ...
Door-to-door transit accessibility using Pareto optimal range queries Universiteit Hasselt
Public transit is a backbone for well-functioning cities, forming a complicated system of interconnecting lines each with their own frequency. Defining accessibility for public transit is just as complicated, as travel times can change every minute depending on location and departure time. With Pareto optimal journeys it is possible to look beyond the earliest arrival times and also optimize for the shortest travel time, as travellers base their ...
A travel time-based variable grid approach for an activity-based cellular automata model Vrije Universiteit Brussel KU Leuven
Urban growth and population growth are used in numerous models to determine their potential impacts on both the natural and the socio-economic system. Cellular automata (CA) land-use models became popular for urban growth modelling since they predict spatial interactions between different land uses in an explicit and straightforward manner. A common deficiency of land-use models is that they only deal with abstract categories, while in reality ...
Within day rescheduling microsimulation combined with macrosimulated traffic Universiteit Hasselt
The concept of rescheduling is essential to activity-based modeling in order to calculate effects of both unexpected incidents and adaptation of individuals to traffic demand management measures. When collaboration between individuals is involved or timetable based public transportation modes are chosen, rescheduling becomes complex. This paper describes a new framework to investigate algorithms for rescheduling at a large scale. The framework ...
Biophysical aspects of handcycling performance in rehabilitation, daily life and recreational sports; a narrative review KU Leuven
AIM: In this narrative review the potential and importance of handcycling are evaluated. Four conceptual models form the framework for this review; (1) the International Classification of Functioning, Disability and Health; (2) the Stress-Strain-Capacity model; (3) the Human-Activity-Assistive Technology model; and (4) the power balance model for cyclic exercise. METHODS: Based on international handcycle experience in (scientific) research and ...
