Why Promising Transportation Technologies Often Fail to Scale

How transportation leaders can recognize the pilot-to-scale gap and begin moving next-generation mobility technologies toward more widespread adoption.

A successful pilot can prove that a transportation technology works, but it does not prove that the technology can successfully scale.

That distinction is becoming increasingly important as transportation agencies explore connected infrastructure, artificial intelligence, advanced transportation systems and autonomous technologies. Many promising technologies have demonstrated value in real-world environments. The bigger challenge is moving them beyond individual demonstrations and into sustained, widespread use. 

Closing the distance between proven and pervasive may be the hardest part of transportation innovation.

Why is it difficult to scale transportation technology?

Transportation technology does not move easily from successful pilot to widespread adoption.

Deployment can feel like the culmination of years of research, development, testing and validation. In reality, putting technology into the field can mark the beginning of another important phase: operating it, optimizing its performance and determining whether it can scale.

Some intelligent transportation systems have already made that journey. Technologies such as traffic signal control, dynamic message signs, traveler information and safety-focused intelligent transportation systems have become accepted elements of transportation operations across the country.

But the next generation of intelligent mobility technologies presents a different challenge.

Connected vehicles and infrastructure, AI-enabled transportation operations and autonomous transportation have demonstrated their capabilities, yet widespread adoption has not followed at the same pace.

The “messy middle” between innovation and scale

This stage is sometimes called the “messy middle”: the point where a transportation technology has moved beyond initial proof of benefit but hasn't yet become easy to replicate, sustainably funded, interoperable or trusted enough for widespread adoption. A promising deployment can work as intended and still struggle to move beyond the environment where it was demonstrated.

That is often because scaling next-generation mobility technology is not purely a technology challenge.

Standards matter. Interoperability matters. A sound business case matters. Institutional and workforce readiness matter. Public trust matters. Those conditions do not exist independently of one another.

When enough of these conditions align, momentum for adoption can build and accelerate. When these conditions do not, even promising innovations can remain stuck in a cycle of pilots and limited deployments.

From successful somewhere to replicable everywhere

The question facing transportation leaders is not simply whether the next generation of mobility technologies can work. The question is what will allow those technologies to work repeatedly, sustainably and at the scale required to make a broader regional or even national impact.

That is the focus of Battelle’s new executive brief, The Hardest Mile: Understanding the Pilot-to-Scale Gap, the first in a three-part series examining the pilot-to-scale gap in intelligent mobility. The brief looks more closely at where technologies sit in the deployment lifecycle, why promising innovations stall and what it takes to begin moving from successful somewhere to replicable everywhere.
