Abstract: Due to many advances in numerical weather prediction systems over the past several decades, forecasters have been able to steadily improve the accuracy of their weather predictions. With the increases in computational power and the ability to store massive amounts of data, a method for making weather forecasts that had been abandoned several decades ago has become feasible. I will talk about making weather forecasts using large amounts of historical data, go over the project that I worked on during my co-op, and provide some commentary about my experiences at Environment Canada.
Abstract: In September 2010, British Columbia introduced the Immediate Roadside Prohibition (IRP) program. This program put harsher penalties in place for drunk drivers, and is among the strictest traffic law programs in Canada. Similar penalties, including fines and license suspensions, were also put in place for excessive speeders. The objective of my co-op placement was to evaluate the public health benefits of these new traffic laws. Using interrupted time series methods, I explored changes in motor vehicle collision and public health service utilization rates before and after the IRP intervention. During this seminar, I will discuss the challenges associated with modelling these outcomes.
