1. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt
Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

2. The monetary value of urban form: Examining the relationship between accessibilities and attractiveness in Oslo
Sammanfattning : Today and for the foreseeable future we experience a global urbanisation, which requires development of buildings, roads, and plots, also called urban form. Most often it is urban planning and design that determine changes in urban form, and it should be valuable with knowledge of its monetary value. LÄS MER
3. Impacts of Speed Limits and Information Systems on Speed Choice from a Safety Perspective
Sammanfattning : Driving a vehicle is considered a demanding task in a complex dynamic environment. For instance, driving a vehicle on urban roads, where motorized vehicles meet vulnerable road users (VRUs) creates a multifaceted environment with difficult trade-offs and interactions. LÄS MER
4. A Bayesian approach to retrospective detection of change-points in road surface measurements
Sammanfattning : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. LÄS MER
5. Predicting the sound field from aeroacoustic sources on moving vehicles : Towards an improved urban environment
Sammanfattning : In a society where environmental noise is becoming a major health and economical concern, sound emissions are an increasingly critical design factor for vehicle manufacturers. With about a quarter of the European population living close to roads with heavy traffic, traffic noise in urban landscapes has to be addressed first. LÄS MER
