This data has been made available as part of a research project Freight Logistics in Sustainable Cities (CityFreight; project number 308790), funded by the Research Council of Norway and led by Stein W. Wallace, Professor at NHH Norwegian School of Economics. The aim of this project is to provide public authorities with a toolbox for realistically evaluating major decisions that would make freight transportation in a city more energy-efficient and sustainable.
This dataset includes all links within the Bergen municipality collected from the NVDB database provided by Statens vegvesen (Norwegian Public Roads Administration) and contains data under the Norwegian licence for Open Government Data (NLOD) distributed by Statens vegvesen. Where it applies, links were matched with speed limits, height restrictions, roadblocks and turn restrictions (also acquired from NVDB). Numerous errors in the data were corrected according to the actual state (as of March 31, 2021).
Description of variables:
| Variable | Description |
|---|---|
| linkID | Unique identifier of the link |
| geometry | WKT representation of the link using coordinate system EPSG:5973 |
| startNode | Unique identifier of a node where the link originates |
| endNode | Unique identifier of a node where the link ends |
| length | Length of the link in metres |
| road | True if the link is primarily used for driving (corresponds with types enkelBilveg, kanalisertVeg, rundkjøring and rampe from NVDB), False otherwise |
| streetName | Name of a street the respective link is part of |
| streetCode | Unique identifier of a street the respective link is part of |
| MED | True if it is allowed to cover the link in the direction from the start node to the end node, False otherwise |
| MOT | True if it is allowed to cover the link in the direction from the end node to the start node, False otherwise |
| speedLimitMED | Speed limit in km/h in the direction from the start node to the end node |
| speedLimitMOT | Speed limit in km/h in the direction from the end node to the start node |
| heightRestriction | Maximum height of a vehicle allowed to cover the link |
| noFlowMED | List of links connected to the end node which are not allowed to continue on due to a turn restriction or a roadblock |
| noFlowMOT | List of links connected to the start node which are not allowed to continue on due to a turn restriction or a roadblock |
The majority of the apartment data has been acquired from Kartverket (Norwegian Mapping Authority) by using information from the annual “Matrikkelen Adresse Leilighetsnivå” (version 2020) under the CC BY 4.0 licence. The data includes official and complete addresses of buildings in the Bergen municipality, together with unique apartments within each building (if there are any). The data includes address, postal district, statistical unit and town. The estimated population at a building/apartment has been generated through a master’s thesis conducted by Fang and Opedal (2020). For more information on the estimation, kindly refer to the thesis.
