11. The Influence of Customer Agreements and Planning Principles on Rail Freight Performance
Sammanfattning : Rail freight transportation is recognized worldwide as a suitable transportation mode when it comes to long haul transportation of heavy commodities. The industry is also known to be capital intensive, highly dependent on infrastructural developments and requires thorough planning of operations. LÄS MER
12. Surface characterization methods for quality assessment of polyethylene-coated paperboard
Sammanfattning : In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. LÄS MER
13. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches
Sammanfattning : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. LÄS MER
14. Optimization Approaches for Design of Congestion Pricing Schemes
Sammanfattning : In recent years, there has been a growing interest in congestion pricing as a tool for solving traffic congestion problems in urban areas. However, the transportation system is complex and to design a congestion pricing scheme, i.e. to decide where and how much to charge the road users, is not trivial. LÄS MER
15. Simulation Based Evaluation of Advanced Driver Assistance Systems
Sammanfattning : Road transportation is an essential element of mobility in most countries and we can observe an increasing demand for both goods and passenger traffic. There are however important societal and economical problems related to road transportation in terms of congestions, traffic safety and environmental effects. LÄS MER
