Quantitative Risk Assessment (QRA) models have already been developed and used to assess various risks of road tunnels, including the societal risk and expected number of fatalities (ENF). Fire in a road tunnel is considered as the most severe disaster in that road tunnel is an enclosed space. The risk assessment for fire in road tunnels involves a number of parameters. Some of these parameters...

The aim of this research paper is to formulate a road map for implementation of lean techniques within SMEs product development (PD) teams, identifying barriers to change and explaining possible drivers for successful implementation. The research methodology necessary to develop the road map – the IPID cycle – is a combination of different approaches. It combines a literature review, an initial...

A well-developed road network allows all forest activities, including wood harvesting, firefighting and recreational activities. However, forest road construction and maintenance involve economic and environmental costs. For these reasons, forest road network planning is a fundamental phase of forest management, maximising the benefits and reducing costs and impacts. Thanks to modern technologi...

Fu), vkim@ This paper introduces a real-time optimization model that can be used by maintenance managers to develop and evaluate alternative resources allocation plans for winter road maintenance operations. The model takes int...

This paper empirically examines commercialization of university faculty inventions through startup firms from 1994 through 2008. Using data from the Association of University Technology Managers and the 2010 NRC doctoral rankings, our research reveals several findings. We find that university entrepreneurship is more common in bad economic times and that engineering department quality and biolo...

The objective of the University Freedom Act (Hochschulfreiheitsgesetz) in North Rhine-Westphalia is to achieve entrepreneurial universities that are to be steered by their presidents and vice-presidents – in other word, their managers. For this purpose, along with management, leadership is also important. This paper attempts to determine how university managers deal with those tasks. Interviews...

In recent years, the development of the GIS-T (Geographic Information System for Transportation) applications has gained much attention, providing the transportation planners and managers with in-depth knowledge to achieve better decisions. Needless to say, developing a successful GIS for transportation applications is highly dependent on the design of a well-structured data model. Dynamic segm...

Historically, traffic on the Denali Park Road has been limited in order to protect wildlife and improve visitor experience. The Denali Park Road is one example of a park roadway facing increasing visitation and pressure to change or defend the current limits on traffic. To respond to such pressures, park and protected area managers need a greater understanding of the impacts of traffic volume a...
