It will be observed that trips less than 5 miles in length constitute the largest group in all States, ranging between 25.7 percent of all trips in one State and 43.8 percent in another, the percentages in the other nine States lying between these limits. Trips from 5 to 10 miles in length constitute the next largest group, and those from 10 to 20 miles long the third largest group.
The same data that are represented in plate 5 were used to compute the mean and median lengths of trip shown in table 1 for each of the 11 States. The table shows the mean and median trip lengths in miles, in each of the States, separately for cars owned in rural and urban places, in each of four population classes of urban places, and in the State as a whole. The mean of all trip lengths is shown to range from 11.7 miles to 18.7 miles; the median from 6.3 miles to 8.9 miles. The data contained in the table also indicate that trips of passenger cars owned in rural areas are generally shorter than trips of cars owned in cities; and also that the length of trip by city-owned cars increases generally with the population of the city in which they are owned.
