Using Time-Series Analysis to Precisely Identify and Rank Road Hotspots
Alexander Lee Wei Lin
Over the past decades, many ranking methods have been proposed. However, results vary from method to method, and one of the issues behind ranking is the element of subjectivity. One approach to resolve these issues is the use of combined models. One of the combined models is the Enhanced Empirical Bayesian (EB) method that incorporates the use of the similarity measure based on the Proportion Discordance Ratio (PDR). This model is developed to assess and objectively quantify similarity among…

Introduction to Scientific Computing for Planners, Engineers, and Scientists
Liming Wang
Building on the successful scientific computing training program offered by the Software Carpentry (http://www.software-carpentry.org/), the proposed course exposes students in science, engineering, and planning to the best practices in scientific computing through hands-on lab sessions and aims to help students tackle the challenge of "drinking from a hose" when dealing with overwhelming amount of data that is increasingly common in these disciplines. Although computing is now an integral part…
