TransSee

ALT I just wanted to let you know how much I like Transee, in particular: The lightweight interface with minimal padding and styling. The custom prediction ranges and vehicle locations/history (these have been very accurate and useful for planning, saving me multiple hours per week of waiting). The ability to see lower-level historical and live data (also helpful for planning, and the interface is well-thought-out). The ability to create custom prediction pages with lists of routes and stops (even disjoint ones) by modifying the query parameters. The consistent URLs with a well-designed format. The almost-realtime GTFS data updates. The detailed vehicle information. All of these features together allow me to optimize my transit usage and essentially eliminate waiting longer than 5 minutes for buses while also letting me find fallback options quickly (sometimes involving running a few blocks to catch a different route as it arrives).
