​Transitmix ( is simple way to think about transit in terms of bus requirements and real costs. Developed by a group of Code for America fellows, TransitMix is conceived as “a sketching tool for transit planners (both professional and armchair) to quickly design routes and share with the public.“ Basically, the user draws a route on a map and plugs in span and frequency. To start, pick a city. Then, drag and drop points to snap your bus line to the street grid. By changing variables like headway and peak hours, the app then calculates a vehicle requirement and cost in both hours and dollars, factoring in an adjustable layover ratio, average speed and dollar cost per service hour. The team details their work on GitHub and is looking for feedback. source:
