Examples of TimeSurface

org.opentripplanner.analyst.TimeSurface
A travel time surface. Timing information from the leaves of a ShortestPathTree. In Portland, one timesurface takes roughly one MB of memory and is also about that size as JSON. However it is proportionate to the graph size not the time cutoff.

            EarliestArrivalSPTService sptService = new EarliestArrivalSPTService();
            sptService.maxDuration = (60 * cutoffMinutes);
            ShortestPathTree spt = sptService.getShortestPathTree(req);
            req.cleanup();
            if (spt != null) {
                TimeSurface surface = new TimeSurface(spt);
                surface.params = Maps.newHashMap();
                for (Map.Entry<String, List<String>> e : uriInfo.getQueryParameters().entrySet()) {
                    // include only the first instance of each query parameter
                    surface.params.put(e.getKey(), e.getValue().get(0));
