Van Oort, Bart (author), Cruz, Luis (author), Loni, Babak (author), van Deursen, A. (author)Machine Learning (ML) projects incur novel challenges in their development and productionisation over traditional software applications, though established principles and best practices in ensuring the project's software quality still apply. While using static analysis to catch code smells has been shown to improve software quality attributes...conference paper 2022

Van Oort, N. (author), Ebben, M. (author), Kant, P. (author)Afgelopen CVS congressen is er veel gesproken over nieuwe databronnen die helpen bij de uitdagingen in de OV wereld. De OV chipkaart is één van de bronnen, waarmee we het OV beter en efficiënter kunnen maken. Maar tot nog toe gebruikten we deze data vooral om binnen de lijntjes te kleuren: de data als vervanging van eerdere handmatig verkregen...conference paper 2015

Van der Meijs, P. (author), Genot, M. (author), Van Oort, N. (author)Bus Rapid Transit (BRT) is een interessante hoogwaardige openbaar vervoer oplossing. Als gevolg van de hoge flexibiliteit en kosteneffectiviteit is met BRT relatief snel en eenvoudig een grote kwaliteitssprong te realiseren. Het aantal BRT systemen is wereldwijd de laatste jaren sterk toegenomen. Evenals het aantal systemen, is ook de variëteit...conference paper 2015

Brietzke, D. (author), De Keizer, B. (author), Van Oort, N. (author)We reizen vaker, afstanden worden kleiner, reistijden worden korter en comfort wordt steeds belangrijker . En wie is er nou niet in Berlijn geweest? De vraag naar internationale verbindingen neemt de laatste decennia sterk toe. Het afgelopen jaar is er zelfs een record aantal reizen gemaakt tussen Nederland en Duitsland. De Europese Unie...conference paper 2015

Van Oort, N. (author), Hoogendoorn, S.P. (author), van Lint, J.W.C. (author)Bereikbaarheid en daarmee mobiliteit en transport systemen zijn van vitaal belang van onze steden en regio’s. Verkeer en vervoer spelen een cruciale rol in het mogelijk maken van activiteiten voor mensen en bedrijven. Maatregelen, ingrepen en innovaties laten historisch een verbetering van de bereikbaarheid zien en daarmee van de vrijheid van...conference paper 2015

Van Oort, N. (author), Cats, O. (author)New big data (sources) in the public transport industry enable to deal with major challenges such as elevating efficiency, increasing passenger ridership and satisfaction and facilitate the information flow between service providers and service users. This paper presents two actual cases from the Netherlands and Sweden in which automated data...conference paper 2015

Cats, O. (author), Yap, M. (author), Van Oort, N. (author)Network vulnerability depends on the probability that adverse events occur and on the impacts of such disruptions on network functionality. Most studies on transport network vulnerability have only analysed vulnerability in terms of the reduction in performance indicators given that a disruption occurs. This study presents and applies a method...conference paper 2015

Van Oort, N. (author), Drost, M. (author), Brands, T. (author), Yap, M. (author)The most important aspects on which passengers base their choice whether to travel by public transport are the perceived travel time, costs, reliability and comfort. Despite its importance, comfort is often not explicitly considered when predicting demand for public transport. In this paper, we include comfort level in a modelling framework by...conference paper 2015

Van Oort, N. (author), Van der Bijl, R. (author), Roeske, R. (author)Light rail has been successfully implemented in many urban regions worldwide. Although light rail has been a proven transport concept in many cities, there is much debate on the (societal) cost-benefit ratio of these systems. In addition to the success stories, several light rail projects were not that successful or even failed. In recent years,...conference paper 2015

Van Oort, N. (author), Drost, M. (author), Brands, T. (author)Door de introductie van de OV-Chipkaart komen er grote hoeveelheden data over reizigersstromen in het OV beschikbaar. Naast data over de voertuigprestaties (via GOVI bijv.) hebben de inzichten uit deze reizigersdata een enorm potentieel voor de optimalisatie van het OV-product. Dit artikel verkent de mogelijkheden om, de privacy van reizigers...conference paper 2014

Lee, A. (author), Van Oort, N. (author), Van Nes, R. (author)This paper presents research on synchronization of transfers and its impact on service reliability from a passenger perspective. Passenger reliability is analyzed for the case of a multi-operator transfer node. A method is developed to calculate the passenger centered reliability indicators: additional travel time and reliability buffer time,...conference paper 2014

Van Oort, N. (author), Brands, T. (author), De Romph, E. (author), Aceves Flores, J. (author)Nowadays, transport demand models do not explicitly evaluate the impacts of service reliability of transit. Service reliability of transit systems is adversely experienced by users, as it causes additional travel time and unsecure arrival times. Because of this, travelers are likely to perceive a higher utility from higher reliable transport...conference paper 2014

Van Oort, N. (author), Sparing, D. (author), Brands, T. (author), Goverde, R.M.P. (author)There is a growing pressure on urban public transport companies and authorities to improve efficiency, stemming from reduced budgets, political expectations and competition between operators. In order to find inefficiencies, bottlenecks and potentials in the public transport service, it is useful to learn from recorded operational data. We first...conference paper 2012

Falkena, W. (author), Van Oort, E.R. (author), Chu, Q.P. (author)This paper uses singular perturbation theory in order to design a backstepping control system. Earlier applications using singular perturbation theory for control of non-affine systems exist, but here the focus is shifted to uncertain systems. Dealing with uncertainties in this way could be a major benefit for certification of advanced control...conference paper 2011

De Weerdt, E. (author), Van Oort, E.R. (author), Van Kampen, E. (author), Chu, Q.P. (author)Level set methods are used to determine the reachable set for a given time domain. In the aerospace industry level set methods are used to determine for example flight envelopes. A new level set method is presented which uses interval analysis to give guaranteed bounds on the solution. Unlike the current grid-based methods the new method does...conference paper 2011
