Feel the art: Creating museum involvement by tapping universal human concerns

Desmet, P.M.A. (author), Hekkert, P.P.M. (author), van Erp, J. (author)

This paper reports an experience-driven design project that was commissioned by the Amsterdam Rijksmuseum. The aim was to cause a shift in the relationship between visitors and the art collection from one that is experienced as ‘distant’ to one that is experienced as ‘committed’. In five steps, an online application was conceptualised, developed...

Designing with Meaningful Data: Deep personalisation in the air travel context

Yuan, Mengqi (author), Price, R.A. (author), van Erp, J. (author), Osorio Socha, Jorge Andrés (author)

Data and artificial intelligence (AI) are revolutionising the way customers interfacewith organisations and vice versa. However, there is limited knowledge regarding howdata and AI are used as material during the design process. It is to this practice-research gap that this paper responds, by providing practical insight into a projectbetween a...

Matching Data and Emotions for Designing Personalized Digital Experiences

Montijn, Myrthe (author), Calabretta, G. (author), van Erp, J. (author)

Digital innovations in-store are often unnecessary, unintuitive and uncomfortable and mostly make use of personal data for one-way messaging instead of meaningful interpersonal interactions. Digital initiatives are also more focused on enhancing the shopping experience (even unsuccessfully) instead of building consumer-brand relationship through...

Ramp Metering with Real-Time Estimation of Parameters

Knoop, V.L. (author), Taale, Henk (author), Meulenberg, Michel (author), van Erp, P.B.C. (author), Hoogendoorn, S.P. (author)

Demand exceeding the capacity of a bottleneck will create congestion upstream of that bottleneck. Once this congestion occurs, the maximum flow through this bottleneck decreases (capacity drop). By limiting the flow towards the bottleneck, one can prevent or postpone the capacity drop and the accompanying congestion. In case the bottleneck is...

Estimating the fundamental diagram using moving observers

van Erp, P.B.C. (author), Thoen, Sebastiaan (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)

The fundamental diagram (FD) describes the relation between the flow and density in equilibrium conditions. In this paper, we propose an estimation approach to estimate the FD based on data from moving observers. This approach consists of two main steps: (1) estimate flow and density for space-time areas based on trajectories of moving observers...

Bayesian decision theory: A simple toy problem

van Erp, H.R.N. (author), Linger, R.O. (author), van Gelder, P.H.A.J.M. (author)

We give here a comparison of the expected outcome theory, the expected utility theory, and the Bayesian decision theory, by way of a simple numerical toy problem in which we look at the investment willingness to avert a high impact low probability event. It will be found that for this toy problem the modeled investment willingness under the...

Empirical MFDs using Google Traffic Data

Knoop, V.L. (author), van Erp, P.B.C. (author), Leclercq, Ludovic (author), Hoogendoorn, S.P. (author)

<br/>The Macroscopic Fundamental Diagram (MFD) describes the relation between accumulation and speed in a zone. While theoretically expected, empirical validations have been done with limited numbers of floating car (e.g., taxi) data, and loop detectors. This paper will verify existence, shape and crispness of the MFD using Floating Car Data ...

A Bayesian framework for risk perception

van Erp, H.R.N. (author)

We present here a Bayesian framework of risk perception. This framework encompasses plausibility judgments, decision making, and question asking. Plausibility judgments are modeled by way of Bayesian probability theory, decision making is modeled by way of a Bayesian decision theory, and relevancy judgments are modeled by way of a Bayesian...

Relative Flow Data: New Opportunities for Traffic State Estimation

van Erp, P.B.C. (author)

Traffic state information is crucial for different applications, e.g., in design and operation of road traffic networks, and in navigation services. Traffic sensing data, e.g., loop-detector data, may directly provide the desired information. Alternatively, the traffic state information may be estimated with data that only provides partial and...

Real-time schattingen van voertuigaccumulatie met FCD

van Erp, P.B.C. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)

In ruwe vorm zijn floating car data rijk en uiterst gedetailleerd. Het punt is alleen dat we om privacyredenen niet met die ruwe data mogen werken – we moeten het doen met geaggregeerde data die door een privacyfilter zijn gehaald. Is daarmee nog enige verkeersmanagement-eer te behalen? Jawel, mits je de FCD slim combineert met bijvoorbeeld...

Complexe neurologische aandoeningen in de langdurige zorg: Een verkenning van aantallen, patiëntkenmerken en indicaties

Hommel, Danny (author), Plouvier, Annette (author), Krijthe, J.H. (author), Lavrijsen, Jan (author), Koopmans, Raymond (author), van Erp, Willemijn (author)

Veel patiënten met een complexe neurologische aandoening, zoals de ziekte van Parkinson, multiple sclerose of restverschijnselen van niet-aangeboren hersenletsel, doen vroeg of laat in hun ziekteproces een beroep op de langdurige zorg. Dat deze mensen een andere zorgbehoefte hebben dan de algemene verpleeghuispopulatie is bekend, maar van hun...

Estimation of the Change in Cumulative Flow over Probe Trajectories using Detector Data

van Erp, P.B.C. (author), Knoop, V.L. (author), Smits, Erik Sander (author), Tampère, Chris (author), Hoogendoorn, S.P. (author)

Detector data can be used to construct cumulative flow curves, which in turn can be used to estimate the traffic state. However, this approach is subject to the cumulative error problem. Multiple studies propose to mitigate the cumulative error problem using probe trajectory data. These studies often assume “no overtaking” and thus that the...

Remote contextmapping and prototyping during lockdown, a study case

van Nifterik, W.B. (author), Sleeswijk Visser, F. (author), van Erp, J. (author)

In co-design, solutions are generated to serve people’s needs, short term and/or long term, through their involvement in parts of the design process. Methods like contextmapping and explorative prototyping serve these participatory processes. They help designers to step into the users’ shoes, to explore design solutions from and with their...

Unravelling the hip-spine dilemma from the CHECK-cohort: Is sagittal pelvic morphology linked to radiographic signs of femoroacetabular impingement?

van Erp, Joost H.J. (author), Gielis, Willem Paul (author), Arbabi, Vahid (author), de Gast, Arthur (author), Weinans, Harrie (author), Kaas, Laurens (author), Castelein, René M. (author), Schlösser, Tom P.C. (author)

Introduction: To date the aetiology of femoroacetabular impingement (FAI) is still not completely understood. There are mechanical theories that suggest symptomatic FAI is linked to sagittal pelvic morphology and spinopelvic-femoral dynamics. The aim of this study is to evaluate the relation of sagittal pelvic morphology and orientation to...

Macroscopic Traffic State Estimation: Understanding Traffic Sensing Data-Based Estimation Errors

van Erp, P.B.C. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)

Traffic state estimation is a crucial element in traffic management systems and in providing traffic information to road users. In this article, we evaluate traffic sensing data-based estimation error characteristics in macroscopic traffic state estimation. We consider two types of sensing data, that is, loop-detector data and probe speed...

Deriving proper uniform priors for regression coefficients, Parts I, II, and III

van Erp, H.R.N. (author), Linger, R.O. (author), van Gelder, P.H.A.J.M. (author)

It is a relatively well-known fact that in problems of Bayesian model selection, improper priors should, in general, be avoided. In this paper we will derive and discuss a collection of four proper uniform priors which lie on an ascending scale of informativeness. It will turn out that these priors lead us to evidences that are closely...

Inquiry calculus and the issue of negative higher order informations

van Erp, H.R.N. (author), Linger, R.O. (author), van Gelder, P.H.A.J.M. (author)

In this paper, we will give the derivation of an inquiry calculus, or, equivalently, a Bayesian information theory. From simple ordering follow lattices, or, equivalently, algebras. Lattices admit a quantification, or, equivalently, algebras may be extended to calculi. The general rules of quantification are the sum and chain rules. Probability...
