PRIDE: A Privacy-Preserving Decentralised Key Management System

Kester, David (author), Li, T. (author), Erkin, Z. (author)

There is an increase in interest and necessity for an interoperable and efficient railway network across Europe, creating a key distribution problem between train and trackside entities’ key management centres (KMC). Train and trackside entities establish a secure session using symmetric keys (KMAC) loaded beforehand by their respective KMC...

Improvement of Network Performance by In-Vehicle Routing Using Floating Car Data

Klunder, G.A. (author), Taale, Henk (author), Kester, L (author), Hoogendoorn, S.P. (author)

This paper describes a study which gives insight into the size of improvement that is possible with individual in-car routing advice based on the actual traffic situation derived from floating car data (FCD). It also gives an idea about the required penetration rate of floating car data needed to achieve a certain degree of improvement. The...

The effect of inaccurate traffic data for ramp metering: Comparing loop detectors and cameras using information utility

Klunder, G.A. (author), Taale, H. (author), Kester, L. (author), Hoogendoorn, S.P. (author)

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

Datafusie - wat wordt ermee bedoeld en wat heb je eraan?

Klunder, G. (author), Hoogendoorn, S.P. (author), Kester, L. (author), Taale, H. (author)

Heb je het met iemand over verkeersdata, dan valt – naast de zo populaire kreet ‘big data’ – bijna altijd de term datafusie. In veel gevallen is het echter helemaal niet zo duidelijk wat daar nu precies mee wordt bedoeld en waarom het zinvol zou zijn. In deze tutorial daarom een korte introductie. We gaan daarbij vooral in op de kwaliteit van...

An Empirical Exploration of the Antecedents and Outcomes of NPD Portfolio Success

Kester, L. (author), Hultink, H.J. (author), Griffin, A. (author)

The manuscript first combines theory and previous empirical findings to build a model of new product development portfolio success. Because relationships between product development portfolio decision-making effectiveness, portfolio success and firm-level success have not previously been investigated, we generate propositions that the...

Relationship between application scale and maximum time latency in intelligent transport solutions

Knoop, V.L. (author), Van Lint, J.W.C. (author), Kester, L. (author), Passchier, I. (author), Vries, J. (author)

Congestion is a major problem in large urbanised areas. Intelligent Transport Solutions aim to reduce this problem. Generally, traffic is monitored using sensors, this data is processed, a traffic state is estimated and a control measure is computed and implemented. The availability and quality of the data and the processing time of the...

Toward a general model of portfolio decision making

Kester, L. (author), Griffin, A. (author), Hultink, E.J. (author), Lauche, K. (author)

We develop a general model of how new product development portfolio decisions are made based on four diverse case studies. Previous research has investigated portfolio decisions as individually discrete decisions. We find that portfolio decision-making has to be considered as an integrated system of domain-based processes that produce evidence-,...
