The number of stops made varies from city to city and is based on population density and vehicle size.
The average amount of stops within a route typically consists of three to four stops. Since rides are grouped geographically, stops are likely to be in quick succession due to higher density. For areas that are more spread out, smaller vans and fewer stops are likely but will also be more spread out in time and distance.
Number of stops also vary upon time of day, time of year, and the number of passengers going to or from your area.
