Data Infrastructures for Asset Management Viewed as Complex Adaptive Systems

Data infrastructures represent information about physical reality. As reality changes, data infrastructures might also be subject to change. Researchers have increasingly approached physical infrastructures as being complex adaptive systems (CAS). Although physical infrastructures are often approached as CAS, the underlying data infrastructures...

Innovation with open data: Essential elements of open data ecosystems

Open data ecosystems are expected to bring many advantages, such as stimulating citizen participation and innovation. However, scant attention has been given to what constitutes an open data ecosystem. The objective of this paper is to provide an overview of essential elements of open data ecosystems for enabling easy publication and use of open...

A conceptual framework for road safety and mobility applied to cycling safety

Scientific literature lacks a model which combines exposure to risk, risk, and the relationship between them. This paper presents a conceptual road safety framework comprising mutually interacting factors for exposure to risk resulting from travel behaviour (volumes, modal split, and distribution of traffic over time and space) and for risk ...

Public-Private Collaboration: How Private Involvement can Contribute to Network Performance

raditionally, in infrastructure planning, private contractors are engaged at the end of the plan development stage on the basis of a request for proposals, after the conceptual design is finished and the main decisions have been made. They are responsible for final engineering and construction and, separately, for maintenance of the...

Some approaches to reduce transport time of intermodal services: Smart rail investments

Rail intermodal services are an alternative to all-road services if the average transport time offered by these services is at least comparable. One of the determinants of transport time is how well actors in the transport chain cooperate. In this paper it is shown that substantial improvements in rail transport time are possible if these actors...

Three theses on the internationalization of infrastructures

Infrastructures become more intertwined, with time, on an international level. This has important consequences on infrastructure technologies, corporate organizations and economic institutions.

Building the Next Generation of Digital Government Infrastructures

Digital Government Infrastructures provide generic functionalities that are used by large numbers of users. Typically, they have no central authority, are governed by networks and contain both emerging and purposefully designed parts. Their use varies over time, and a large number of individuals use them for different purposes. The basic digital...

Noise valuation in ex-ante evaluations of major road and railroad projects

In many European countries, the impact of new road and railroad infrastructure is assessed by performing a cost-benefit analysis, monetising as many relevant effects as possible. Considering that noise is a major external effect of traffic, this paper will systematically review the guidelines for monetising noise in different European countries....
