Ottawa’s new light rail line opened to the public last month, more than a year overdue, and this week the bus routes change to account for that fact. The new system network map (downtown inset above) strongly resembles the map released last year, which showed what the bus routes would have been had the LRT opened back then, somewhat less late, but there are some subtle changes here and there.

Meanwhile, planning is under way for the next stage of LRT construction. The City of Ottawa has an interactive map showing where the new (and existing) lines will be going: it’s a track network map that shows every crossover and platform, and goes a long way toward satisfying my curiosity.

Last week OC Transpo, the City of Ottawa’s transit service, unveiled a new network map (PDF) that shows the transit routes that will be in effect after the new LRT opens, which is (at the moment) scheduled to take place in November. From a cartographic perspective, what’s interesting is that OC Transpo’s new map adopts a diagrammatic, non-geographical design after years of their maps simply overlaying transit lines over a city map (see, for example, the latest, pre-LRT transit map, PDF). The approach allows the map to enlarge the more densely served core and inner suburbs and shrink the larger, but less service-dense outer suburbs—which is exactly what diagrammatic transit maps of sprawling cities are good for.
