This project produced a series of graphs that compared the distribution of ratios for car-to-transit job accessibility in American cities. The graphs include mean and median lines for the three analyses, which compare distributions across 10, 30, and 50-minute travel time intervals. A high car-to-transit job accessibility ratio means that car-travelers in that city have a considerable advantage over a transit rider with regard to job accessibility.

This analysis compares the number of jobs that can be reached by private vehicle (car) to the the number of jobs that can be reached by public transit in 46 of the U.S. most populous cities. The analysis compares ratios Clicking the teardrop icon on the right of the analysis title in the right sidebar will recolor the dots on the map in proportion to the cities’ job accessibility ratio. Cities with darker dots have a higher car-to-transit job accessibility ratio, which means that car-travelers in that city have a considerable advantage over a transit rider with regard to job accessibility. Clicking on a dot will open a dialogue that provides the exact car-to-transit job accessibility ratio for that city using 10, 30, and 50-minute travel times.
