This dissertation consists of five papers and an introduction. In Barriers in travel models, the focus is on modelling mobility in border regions, both borders within nations and between nations. We use travel surveys and networks from Sweden and Norway to model the barrier effect caused by the borders in the region between two counties on each side of the national border. In Identifying local ...

the velocity data of seismic waves in a region has an important role in locating occurred events. information such as velocity ratio of vp/vs and velocity curves for pg, pn, sg, and sn phases directly affect the locating results. it is well known that the vp/vs ratio can be used to predict lithology, and that s-waves are sensitive to microcracks aligned by the present day stress field. also, th...

In this work we present a method to be used in decision support system (DSS), which solve the Vehicle Routing Problem with Time Windows. In order to find a good estimation of customers’ delivery time, we consider the fluctuations of the travel time. Solving the routing problems with time constraints without taking into account the fluctuations of the travel time during the day, can lead to seri...

As a consequence of extensive urban growth, local transportation systems are facing enormous challenges, leading to massive investments in infrastructure and travel demand management measures to steer demand for specific travel modes. Meanwhile, technological advancements are creating unprecedented opportunities for collecting and utilizing travel data at previously unknown levels of detail. Su...
