Why Portland Prefers Compact Buses Over Larger Ones

Portlanders, myself included, have been commuting through the bustling city streets since 2018. Despite owning an office in Portland, bicycling, and driving, I find myself frequently riding the Trimet 152 bus. One aspect that confounds me is the use of 30-foot buses on the Trimet 152 route. In this article, I aim to address the reasons why Portland employs smaller buses on many of its routes, specifically the Trimet 152, addressing the unique challenges faced by the city and why smaller buses are the preferred choice.

The Necessity of Compact Buses

One of the primary reasons Portland utilizes smaller buses, such as the 30-foot Trimet 152, is due to the city's network of streets that are often narrow. Narrow streets are a distinctive characteristic of Portland's urban fabric, with many residential and business areas interspersed throughout the city. These narrow streets present unique challenges when it comes to bus operation and maintenance. Here are several reasons why compact buses are necessary and advantageous:

Narrow Streets and Limited Space: Portland’s streets are narrower than those in many other cities. Narrow streets can make it difficult for standard 40 to 60-foot buses to navigate certain intersections and curves without jeopardizing traffic flow and risking congestion. Improved Traffic Flow: Smaller buses, such as the 30-foot models, can maneuver more efficiently through tight spaces, reducing traffic disruptions and improving overall traffic flow. This enhances the experience for both bus passengers and other road users, maintaining a smoother and more predictable traffic environment. Reduced Intersection Disruptions: The use of smaller buses means that intersections can be more effectively managed, reducing the frequency of bus stops and turns that can cause delays and back-ups.

Driver Competence and Responsibility

Another factor contributing to the use of compact buses in Portland is the issue of driver competence and responsibility. Despite some drivers' apparent failure to observe designated "stop zones" at intersections, it is important to note that the design of these stop zones is intended to facilitate safe bus navigation in tight spaces. Here’s how this works:

The "stop zones" designed on intersections with large "X" markers are specifically created to aid buses in making tight turns and stopping safely. These zones are designated to ensure that buses can navigate the tight turns and intersections without danger or obstruction. However, appropriate driver training and responsibility are paramount in ensuring that buses adhere to these rules.

While some drivers may fail to observe these guidelines, it is important to recognize that the presence of stop zones is a positive feature that supports safe bus operation. It is the duty of the drivers to use these zones appropriately, and any violations highlight the need for ongoing training and regulatory enforcement.

Economic and Environmental Advantages

Compact buses like the 30-foot models also offer several economic and environmental advantages:

Economic Efficiency: Smaller buses are generally less expensive to purchase and maintain compared to larger ones. This makes it a more cost-effective solution for the city, allowing for a more efficient allocation of resources. Environmental Impact: Smaller buses typically consume less fuel and produce lower emissions, contributing to Portland's goal of reducing environmental impact. This aligns with the city’s commitment to sustainable and green transportation. Comfort and Assistance: Compact buses often provide a more comfortable and accessible experience for passengers, particularly those with mobility challenges, given the proximity to stops and the ease of door access.

Conclusion

Given the unique characteristics of Portland’s streets and the operational challenges faced by bus drivers, the use of smaller buses like the Trimet 152 is not only a practical necessity but also a cost-effective and environmentally responsible choice. While there are undoubtedly drivers who may not adhere to all regulations, it is important to recognize that the use of compact buses supports smoother traffic flow, efficient navigation, and sustainable transportation in a city that values both functionality and environmental stewardship.

As someone who has been commuting in Portland for years, I hope this article provides a clearer understanding of why compact buses are the preferred choice for bus routes such as the Trimet 152. It is a decision that reflects the city’s commitment to effective urban planning and sustainable transportation solutions.
