Yannick Brosseau
Yannick is a versatile computer engineer working mostly on open source projects. He did is first contribution to OpenStreetMap in 2010 and is an active member of the Montréal community. He is a research professional at the Chaire Mobilite lab at Polytechnique Montreal writing for their open source transit planning platform Transition platform and working on their backend infrastructure. He has teached several course, including parallel programming and embedded software development using OSS tools. And in his spare time, he's helping startups figure out their software development and infrastructure needs. Previously, he did various work around the Linux Kernel.
Session
Transport models routinely anchor points of interest (POIs) at the centroid of their building or parcel. On large multi-building sites, this can misrepresent pedestrian access, distorting first-/last-mile transit access, wheelchair routing, and curbside drop-off precision. We quantify how explicit entrance=* detail in OSM shifts accessibility-style metrics relative to centroid proxies. The study uses a global, population/built-volume-weighted random sample to compare centroids against the nearest main entrance. We release the full toolchain that persists measurements between POI / entrance / centroid anchors and the nearest road network and transit stop.
