For this purpose, we observe ten fixed links on the western coast of Norway. Different linear regression models with several independent variables in different time periods are estimated for two situations; after the opening of the fixed links, and after the toll removal on the fixed link. The results show that the differences between forecast and real population after the opening of the fixed link are not related to any of the observed explanatory variables. On the other hand, the mismatches after the toll removal are associated with the travel time and cost reductions between the main activity centre in the affected municipality and the closest urban district. In addition, the differences in housing prices is also a significant variable, correlated to the number of total jobs per individual. This reflects the differences among the affected and the newly reachable areas in size and labour opportunities.
