planning that often gets neglected despite the impact it has on traffic operations and the environment. In this study, the effect that UFT has on a network is inspected. The purpose of this master’s thesis is to examine the impact that UFT has on the network performance around the shopping mall Kungsmässan, located in Kungsbacka, using the traffic simulation software PTV VISSIM. The study also aims to investigate the environmental impact that the traffic has, namely the air quality, by inspecting the NOx and PM10 emissions. For this, EnViVer Pro is used. These investigations are conducted for the year 2021 to see the current network performance and 2030, mainly to compare the emission values with the environmental goals of 2030 and 2045 set by the Swedish Government and the EU. A literature study is provided to present information for further understanding of the thesis, such as emission details, models used in the study and explanations of some relevant PTV VISSIM tools. Data provided by Aranäs AB, Norconsult AB, the Swedish Administration of Transportation, and Ramboll, is analysed, calibrated, validated and used as input values in PTV VISSIM. To determine the impact that UFT has on the study area, two scenarios for the year 2021 are used: one where all vehicles are accounted for and another consisting of only light vehicles. Two additional scenarios of the same type are used for the prognosis, where the input data has been altered. Based on the results from the simulations, the environmental impact assessment (EIA) is produced in EnViVer Pro. The results showed that UFT significantly effects the traffic flow but that the impact will decrease over time. This is likely due to a decrease in the share of UFT in the future. Furthermore, the EIA shows that the NOx emissions exceed the hourly exposure, according to the limitations set by the Swedish government. PM10 do not exceed the national regulation’s daily limit value. However, in the most critical points of the network, where vehicles decelerate, accelerate and form queues, the concentration of the pollutant is close to the limit value. In conclusion, the study shows that the UFT has a substantial impact on the network performance and air quality, both now and in the future. Thereby, the results indicate on the importance of establishing a sustainable urban logistics plan in order to achieve the national and international objectives for the years 2030 and 2045.
