The density of vehicles in cities of today has increased to a level making it necessary for changes in the transportation system. One possible solution is goods deliverance outside ordinary working hours, but such a solution needs an acoustical acceptance from society. The aim of the project was to find an acoustic understanding of the questions around a “last mile” distribution corridor used outside ordinary working hours. The purpose was also to create a methodology for specifying such a vehicle acoustically. The project has delivered significant knowledge and a good understanding for the prerequisite of this type of corridor and vehicle. Chalmers has created a calculation methodology for future work with acoustical optimization of vehicles in transport corridors. The acoustic work has resulted in a better understanding of acoustical demands related to upcoming changes in the transportation system. The acoustic work also indicates there are several solutions for distribution corridors for use outside ordinary working hours and depends on the context and implies cooperation between all involved actors.
