In the mid-twentieth century, as city bus companies started to grow, economies of scale became a critical factor in their operation. Economies of scale occur when increasing the scale of production leads to a decrease in the cost per unit. When a bus company grows larger, it can reduce expenses such as fuel, maintenance, and labor on a per-passenger basis. This results in lower overall costs and allows for affordable pricing for the consumers.
- Larger companies can buy buses and parts in bulk, leading to discounts.
- They can optimize routes and schedules to minimize fuel consumption and maximize seat occupancy.
- Administrative and operational efficiencies reduce overhead costs.
As these companies grew bigger, they became more efficient, making it challenging for smaller companies to compete. The inability of smaller companies to match the cost efficiency and service level of larger ones led to a natural consolidation. Eventually, many cities found it more sensible to support a single, larger bus company, allowing them to achieve consistent, low-cost service for urban populations.
