  • Local Labour Market Effects of Transport Investments
    TØI report 1057/2010 Author(s): Øystein Engebretsen, Anne Gjerdåker Oslo 2010, 105 pages Norwegian language Summary: Local labour market effects of transport investments Improvements in infrastructure may facilitate commuting between neigh- bouring regions, which in turn may stimulate the regional integration of local labour markets. In Norway, the average travel time to work has increased by more than 20 percent since the mid-1980s. The increase in commuting may be interpreted as a regional integration of labour markets, in response to improved accessibility and increased range. The increase has been largest in the peripheral municipalities. Studies of three Norwegian infrastructure investments – the Korgfjell tunnel, the Triangle Link and the main road (Rv5) between Førde and Florø – demonstrate that the investments have led to reductions in travel time and increased commuting. This in turn results in a more varied and effective labour market, providing greater opportunities for employment and economic growth, and a better matching of skills. The regional integration of labour markets may therefore ideally serve three aims: reducing unemploy- ment, improving access to labour, and securing a decentralised settlement structure. The report is based on an empirical analysis of the relationship between invest- ments in transport infrastructure and regional development, exemplified by an analysis of commuting and employment patterns. The analysis draws on a statistical analysis of commuting flows, settlement and employment patterns at a low level of aggregation. The statistical analyses are supplemented by interviews with firms and local authorities in selected case study areas. Together, the two data sources provide insights into the local consequences of specific infrastructure investments.

  • Local Labour Market Effects of Transport Investments: the Case of Two Norwegian Regions
    Local labour market effects of transport investments: The case of two Norwegian regions Anne Gjerdåker and Øystein Engebretsen Institute of transport economics, Oslo, Norway Email: [email protected] Abstract: Improvements in infrastructure may facilitate commuting between neighbouring regions, which in turn may stimulate the regional integration of local labour markets. In Norway, the average travel distance to work has increased by more than 20 percent since the mid-1980s, while the average travel time has remained constant. The increase in commuting may be interpreted as a regional integration of labour markets, in response to improved accessibility and increased range. The increase in travel distances has been largest in the peripheral municipalities. Studies of two Norwegian infrastructure projects demonstrate that these investments have led to reduced travel time and increased commuting. This in turn results in a more varied and effective labour market, providing greater opportunities for employment and economic growth, and a better matching of skills in the labour market. In both cases there has been an increase in commuting flows, although to varying degrees. The variation may be explained by the composition of the industry structure and employment opportunities within the two regions. Increased spatial competition may result in redistributive rather than generative growth, especially with regards to the location of service activities. The paper draws on a statistical analysis of commuting flows, settlement and employment patterns at a low level of aggregation. A detailed analysis of commuting between basic statistical units for the years 2001 and 2007 reveals a commuting pattern that is not discernible when using data at the municipality level.

  • Description and Structural Analysis of a Marine Bridge for the Digernessund Crossing
    Description and Structural Analysis of a Marine Bridge for the Digernessund crossing Elise Hellvik Marine Technology Submission date: June 2018 Supervisor: Bernt Johan Leira, IMT Norwegian University of Science and Technology Department of Marine Technology NTNU Norwegian University of Science and Technology Department of Marine Technology Master Thesis, Spring 2018 for Master Student Elise Hellvik Description and Structural Analysis of a Marine Bridge for the Digernessundet crossing Beskrivelse og strukturanalyse av et marint brukonsept for kryssing av Digernessundet Marine bridges (i.e. floating bridges, submerged tunnels and more traditional bridge types with floating foundations) are relevant for crossing of very deep and wide lakes or fjord systems. In order to compute the static and dynamic response of these bridges, the joint properties of the entire hydro-elastic system need to be accounted for. The objective of the present project is to outline methods for response analysis and illustrate the calculation procedure for a particular bridge concept. The following subjects are to be addressed as part of this work: 1. Review of existing marine bridges and future plans for such bridges. Similarities and differences between the different bridge types are to be highlighted. Loads acting on such bridges are described together with associated structural models. Methods for both static and dynamic response analysis are elaborated and relevant numerical algorithms are described. 2. A global model of a particular bridge (Submerged tunnel for Digernessundet) is to be established in SESAM. Static response analyses are performed. Sensitivity studies of bending moment and axial forces with respect to current direction and profile are performed.
