1. Safety at Rail-Road Level Crossings
Abstract : Safety related to traffic at rail/road level crossings has long been a major issue for rail operators all over the world. Eliminating these level crossings entirely would be a desirable solution. However converting them into separate types is very expensive and not reasonable in many cases, e.g. READ MORE

2. Crossings and maxima in Gaussian fields and seas
Abstract : In this thesis the focus is on crossing points in random fields and the probability distributions of various crossing variables in different applications. The crossing points are generalisations to random fields of points of level crossings by stochastic processes. READ MORE

3. Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics
Abstract : All four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic.

5. Event Prediction and Bootstrap in Time Series
Abstract : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. READ MORE
