RASED: A Scalable Dashboard for Monitoring Road Network Updates in OSM

Understanding the evolution and changes of digital road networks and how it resembles the true physical road network, have been a rich area of study within map analyzers, urban planners, and transportation communities. The main focus was to study OpenStreetMap (OSM) as the most commonly used platform for worldwide digital road networks, and is deemed even more accurate than commercial maps. However, all such studies have been localized to small areas of interest, mainly due to the large scale of the whole OSM road network. This paper presents RASED; a publicly available scalable dashboard to interactively monitor and analyze the evolution of all OSM road network. Using RASED, map analyzers can query and visualize various statistics about the road network daily changes worldwide, which would give a better understanding of the status of map quality and stability anywhere in the world. RASED relies on daily and monthly offline precomputations, accessed via a hierarchical temporal index structure. Experimental results show that RASED queries are always supported in the order of milliseconds, regardless of how large is the query temporal window, which allows highly interactive map analysis.
