Transport poverty research has a blind spot. For decades, the conversation has focused almost entirely on people can they reach hospitals, schools, jobs? These are valid and important questions. But freight is invisible in this literature, and that invisibility has real consequences. When a neighbourhood has poor road quality, unreliable logistics infrastructure, or no last-mile connectivity, it is not just residents who suffer. Local businesses face higher costs, longer lead times, and reduced competitiveness. Small manufacturers cannot scale. Markets fragment. Economic isolation deepens quietly, without anyone naming it as a transport problem. My research tries to name it. The Freight Accessibility Index is an attempt to measure what has been systematically ignored: the degree to which a location is connected to freight networks, and what it costs when that connection breaks down. Warsaw is my case study. Not because it is broken it is not but because even in a well-functioning city, the spatial variation in freight accessibility is striking once you start measuring it. Some corridors perform well. Others carry hidden penalties that compound over time. The goal is not just academic. If we can measure freight accessibility the way we measure public transport accessibility, we can start designing policy around it. We can justify infrastructure investment in the right places, for the right reasons. That is the work. It is slow, sometimes frustrating, and occasionally feels absurdly niche. But someone has to count the invisible things.

### When infrastructure quietly fails Infrastructure rarely fails in a visible or dramatic way. It does not collapse, nor does it cease to function. It continues to carry traffic and connect locations. However, over time, it begins to introduce small but persistent inefficiencies. Travel times become slightly longer. Surface conditions deteriorate. Minor delays emerge at points where none should exist. Individually, these effects appear negligible. Collectively, they alter the performance of the system. For freight movement, such changes are particularly significant. Increased costs, reduced reliability, and declining route viability emerge not from disconnection, but from inefficiency within existing networks. This form of failure is difficult to detect. It is not reflected in conventional representations of infrastructure, such as maps or network diagrams, and it rarely prompts immediate intervention. Instead, it accumulates gradually. Over time, it produces disparities between locations that appear equivalent in terms of connectivity. Understanding this requires moving beyond the question of whether infrastructure exists. It requires examining how infrastructure performs under real conditions. In transport systems, performance is not defined solely by connectivity, but by the quality, reliability, and efficiency of movement that such connectivity enables.
