Development Economics (and the United States) Part I: Savings Theory

During my Master's degree, I took a course in Development Economics from Cynthia Kinnan* (which had nothing to do with transportation directly). Throughout the course, I noticed that many of the concepts in the course could easily be applied to the United States. A lot of the statistics and economic

Scraping Heroes of the Storm Competitive Information with Scrapy

I have previously written about my Glicko ratings of competitive Heroes of the Storm (HotS) teams, and how I put that information into a SQLite database. Up to this point though, I have been entering all of this information manually. In order to do the kind of analyses that I

Setting Up SQLite on Windows 10

I recently wrote a post on rating teams in Heroes of the Storm and used a regular CSV to store all the data for my ratings. To be honest, that worked perfectly fine although I have been hoping to do some more advanced analysis, particularly looking into rating players. While

Is the Michigan Left actually better?

I was recently visiting a friend in Detroit and I was curious about whether the 'Michigan Left' was actually the safer and more efficient solution that Michigan's Department of Transportation (MDOT) claims it is. If you haven't been to Michigan, A Michigan left is an at-grade intersection design which replaces

Recreating FiveThirtyEight's Footer

FiveThirtyEight's charts are some of the most memorable data visualizations in the world and several people have put a lot of effort into recreating their style. While FiveThirtyEight keeps their actual ggplot2 themes private, Max Woolf and Austin Clemens both created their own versions of the real theme. As Reddit

Modelling a Day of Trips in 3D

In a Survey Design and Analysis course that I'm taking currently, we recently read a paper from Cynthia Chen et al. on "The promises of big data and small data for travel behavior (aka human mobility) analysis" (DOI: [10.1016/j.trc.2016.04.005](http:dx.doi.org/10.

The Original Frank-Wolfe Algorithm in Octave (MATLAB)

I recently took a course in network optimization where we learned a variety of ways to solve the static traffic assignment problem (TAP). For one of our problem sets, we had to use the Frank-Wolfe algorithm in order to define the user equilibrium (UE) in a standard TAP. So why

Illinois's Secretary of Transportation is Bringing IDOT into The Modern Era

Yesterday I was fortunate enough to attend a talk/question and answer session with the current Illinois Secretary of Transportation, Randall Blankenhorn. He was mostly speaking to transportation graduate students and academics at Northwestern University, along with some industry professionals. Governer Bruce Rauner appointed Blankenhorn in January of this year,
