چکیده
The study of sea area accessibility is often overlooked despite the fact that vessel routes’ density at can reflect human activity patterns. Using AIS point data for 2014 and 2018, this paper constructed global daily routes applied kernel estimation method to obtain probability distribution function route over 700,000 grids under a 0.25° regular grid. An model areas was then proposed grid, resulting in assessment 2018. results indicated average maritime value increased from 5.2% 14.4% Accessibility various international trade routes, such as those through Cape Good Hope polar regions, significantly increased. However, Mediterranean near Pacific Islands decreased. This explored temporal spatial variation traffic accessibility, which could enhance our understanding characteristics guide rescue resource allocation, marine species protection, planning.

This licentiate thesis is about the provision of transport infrastructure and the regional impacts of such provision. Three different techniques have been investigated that can be used for the assessment and forecasting of the effects of infrastructure: transport demand models and parametric and non-parametric econometric estimation techniques. The main interest is focused around the regional e...

An overview of previous approaches to the visualisation of uncertainty is presented making the distinction between verity visualisation, where the uncertainty information is an integral part of information presentation and overloading where the information and its uncertainty are displayed separately. In either case the uncertainty information is usually represented as a standard error or confi...
