Physical safety in multiple use of space

As a consequence of an ever-growing population land is getting scarcer, especially in urban areas. In the last decade, the space available above transport infrastructure - such as roads and railway tracks - and existing buildings is being exploited more and more frequently in city centres. The safety issue in such projects should be considered...

Port investment: Towards an integrated planning of port capacity

This study supports strategic planning of a node in a transportation network. It contributes to this by the development of a methodology for planning of port capacity in which port-commercial and public interests are integrated. The focus is the reaction of a single port on a change in the transportation network. A scenario for such change,...

Rail estate, multiple use of space and railway infrastructure

The demand for new development sites, coupled with a wish to preserve green areas outside cities, is provoking increasing interest in inner-city redevelopment. All over Europe, projects of multiple use of space are appearing that involve developing high-quality buildings in which to live and work, while taking account of the history of the city...

Infrastructure and firm dynamics: A micro simulation approach

Abstract not available

Infrastructure asset management: The valuation of complex objects

For two years now, Rijkswaterstaat, an agency of the Dutch Ministry of Transport, Public Works and Water Management, is required to have a financial administration, which is based on accrual accounting principles. This involves the use of a balance sheet and the equivalent of a profit and loss statement. These documents will the basis for...

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...

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 ...

Benchmark analysis of railway networks and undertakings

Benchmark analysis of railway networks and companies has been stimulated by the European policy of deregulation of transport markets, the opening of national railway networks and markets to new entrants and separation of infrastructure and train operation. Recent international railway benchmarking studies which are mostly based on statistical...

Infrastructure Management: Dynamic control of assets

The infrastructure in the Netherlands is crucial for economic development on a national scale. Dramatic increases of transport and mobility accelerate ageing of infrastructure. The GNP of the Netherlands is strongly related to transport and to the two main ports (Port of Rotterdam and Amsterdam Airport Schiphol). The Netherlands is used to a...

Analysing outsourcing policies in an asset management context: A six-stage model

Asset managers of civil infrastructure are increasingly outsourcing their maintenance. Whereas maintenance is a cyclic process, decisions to outsource decisions are often project-based, and confusing the discussion on the degree of outsourcing. This paper presents a six-stage model that facilitates the top-down discussion for analysing the...

Basal Reinforced Piled Embankments

A basal reinforced piled embankment consists of a reinforced embankment on a pile foundation. The reinforcement consists of one or more horizontal layers of geosynthetic reinforcement (GR) installed at the base of the embankment. The design of the GR is the subject of this thesis. A basal reinforced piled embankment can be used for the...

Developing water and sanitation services in refugee settings from emergency to sustainability - The case of Zaatari Camp in Jordan

Developing water and sanitation services in refugee settings from emergency to sustainability - The case of Zaatari Camp in Jordan

Three years after Zaatari camp was established in the Hashemite Kingdom of Jordan, to host Syrian refugees, its population has grown to 82,000 persons. Zaatari is one of the largest refugee camps in the world, in one of the most water scarce areas on earth. Since its establishment, drinking water has been delivered by trucks to communal...

Towards a line-of-sight, implementation of performance measurement by road agencies: A European and Western Australian perspective

This paper is the result of an international, explorative study of the alignment of government and road authority goals from different European countries and Western Australia. The goal of the study is to advance the understanding of the development of performance management of road agencies. Agencies around the world are using performance...

Climate change in asset management of infrastructure: A risk-based methodology applied to disruption of traffic on road networks due to the flooding of tunnels

This paper presents a risk-based method to quantify climate change effects on road infrastructure, as a support for decision-making on interventions. This can be implemented in climate adaptation plans as an element of asset management. The method is illustrated by a specific case in which traffic on a road network is disrupted by the flooding...
