Join Jason and Steph as they discuss the myopic approach of Traffic Engineers in America, and how it ruins cities. They explore the flaws in the profession, critique street-road hybrids, and highlight the loss of historic downtowns due to traffic planning. They emphasize the lack of prioritization for pedestrian safety and the overshadowing of national monuments by car infrastructure.
Transportation engineering education in the US is lacking compared to the Netherlands, resulting in a lack of expertise in designing safe and efficient roads.
US traffic engineers prioritize the flow of traffic over safety and fail to address the needs of pedestrians and cyclists, leading to dangerous road designs.
The US traffic engineering profession lacks balance and fails to consider broader objectives, focusing primarily on moving cars quickly, perpetuating a cycle of road expansion and induced demand.
Deep dives
The Problem with Transportation Engineering Education in the US
Transportation engineering education in the United States is lacking compared to the Netherlands. In the US, transportation engineering is often an afterthought within the broader civil engineering curriculum, with limited coursework and minimal real-world experience. This leads to a lack of knowledge and expertise in designing safe and efficient roads and streets. In contrast, the Netherlands has separate transportation engineering programs that focus on road design, sustainable safety, and field experience. Graduates from these programs have a better understanding of transportation principles and practical design skills.
The Emphasis on Traffic Flow and the Neglect of Safety
Traffic engineers in the US prioritize the flow of traffic above all else. This narrow focus often comes at the expense of safety and other factors that contribute to a well-functioning transportation system. The US standards and practices fail to address the psychological aspects of driving, induced demand, and the needs of pedestrians and cyclists. This results in dangerous road designs, such as stroads, that prioritize high vehicle speeds and create hazardous conditions for vulnerable road users.
The Lack of Balance in Traffic Engineering
The US traffic engineering profession lacks balance and often fails to consider the broader objectives of a transportation system. The emphasis is primarily on moving cars quickly, regardless of the impact on other modes of transportation, such as walking, cycling, or public transit. This one-sided approach leads to a reliance on outdated standards and a failure to address safety, quality of life, and environmental concerns. The focus on flow and congestion reduction also perpetuates a never-ending cycle of road expansion and induced demand.
The Insecurity and Resistance to Change Among Traffic Engineers
Many traffic engineers in the US are resistant to change and hesitant to challenge established norms and standards. This can be attributed to a sense of insecurity within the profession and a fear of questioning the status quo. Experienced engineers may be resistant to new approaches or ideas suggested by younger professionals, creating a stagnation in the field. This resistance hinders innovation and prevents the adoption of more effective and sustainable transportation practices.
The Insanity of Traffic Engineering in North America
The current approach to traffic engineering in North America is often described as insane. The singular focus on maximizing flow and minimizing delay for cars leads to destructive and ineffective road designs. The emphasis on road widening, rather than considering alternative solutions, is bankrupting cities and putting lives at risk. This approach is out of touch with modern urban planning principles, which emphasize safety, multimodal transportation, and the creation of vibrant, livable communities. A shift in mindset and a reevaluation of traditional traffic engineering practices is necessary to create safer, more sustainable transportation systems.
America has Traffic Engineers. The Netherlands has Transportation Engineers. One is concerned with moving as many cars as possible, the other builds transportation systems. In this podcast, I'm joined by Steffen Berr, an American Traffic Engineer turned Transportation Engineer who now lives in the Netherlands. We discuss the myopic approach taken by Traffic Engineers in America, and how it ultimately ruins cities.
Steffen has a great article that is worth reading:
