This page brings together interactive tools, technical resources, experiments, and practical utilities developed across transportation engineering, statistics, education, and related interests. Some are complete and available to use today, while others are still evolving as ongoing projects.
General Applications
CostShare
Track shared expenses, calculate balances, and simplify settling costs, especially when different people share different costs.
PhotoMapper
Upload geotagged field photos and instantly view them on a map at the location they were taken.
Transportation Engineering
Signal Warrants
Evaluate MUTCD traffic signal warrants using transparent calculations, rolling-hour analysis, and printable reports. This is a very user friendly web-based app to document inputs, assumptions, thresholds, and results clearly.
All Way Stop Warrants
Evaluate MUTCD all-way stop control warrants using transparent calculations and clearly documented observations and results.

Experimental and In Development
Graph Builder
Create, compare, and explore mathematical graphs using guided templates, freeform equations, and an interactive shared canvas. I built this app to make function graphing more guided and visual, especially for learning how different parameters change the shape of a graph. Instead of starting with a blank equation box, the app lets users choose function types, adjust parameters, compare multiple graphs, and control the graph paper directly.

Intersection Conflict Points Analyzer
Working on it for now! but it will be used to visualize and analyze vehicle, pedestrian, (and maybe bicycle) conflict points for common intersection configurations.

Intersection Turning Movement Visualizer
Working on it! This will be used to visualize turning movements and traffic paths through intersections to better understand vehicle operations and geometry.
Statistics Test Identifier
Working on it! this will be used to identify appropriate statistical tests by answering a few guided questions about your data and analysis goals.
Other Ideas are there, but that’s pretty much it for now, lol.
