Distance between Bus Stops Consider a city that decreases the distances between bus stops, which decreases the walking time of bus riders by 20 percent, increases the in-vehicle (line-haul) time by 10 percent, and increases operating cost by 10 percent. On the typical bus line, the initial ridership
