Estimated lifetimes of road pavements in Sweden using time-to-event analysis

Maintenance planning of road pavement requires reliable estimates of roads’ lifetimes. In determining the lifetime of a road, this study combines maintenance activities and road condition measurements. The scope of the paper is to estimate lifetimes of road pavements in Sweden with time to event analysis. The model used includes effects of pavement type, road type, bearing capacity, road width, speed limit, stone size and climate zone, where the model is stratified according to traffic load. Among the nine analyzed pavement types, stone mastic had the longest expected lifetime, 32 percent longer than asphalt concrete. Among road types, ordinary roads with cable barriers had 30 percent shorter lifetime than ordinary roads. Increased speed lowered the lifetime, while increased stone size (up to 20 mm) and increased road width lengthened the lifetime. The results are of importance for life cycle cost analysis and road management.

Hur ett företag kan uppmärksammas genom en grafisk profil och en gerillamarknadsföring

The purpose of this thesis was to create a visual identity to the café Trädgårdscafét. This was to increase the awareness of the cafe among the population of Borlänge. To make the company's visual identity visible, we also organized a guerrilla marketing. The outcome of the guerrilla marketing were then measured by calculating the number of guests during a certain period of time and also through a survey conducted in Borlänge.Graphic material, such as a graphic identity, business cards, feel good-cards, store signs, standing information folders to place on the tables and pavement board was created. Flyers and posters were also created for the guerrilla marketing. The basis for this was established in the study of literature, focus groups and surveys. We also kept a regular and open contact with the café owners throughout the project.In a similar procedure a broad knowledge about guerrilla marketing was gathered in order to be able to arrange one our selves.The guerrilla marketing was held for one day in the city of Borlänge. To attract attention, groups of outdoor furniture, decorated with green plants, were placed at different locations, while six marketers handed out flyers and spread information about the café. The guerrilla marketing resulted in that the café's customers grew by nearly twice as many on the day of the guerrilla. Surveys made before and after the guerrilla showed that the awareness of the café grew.
