Worker version v6.0.0

• Decay functions and gravity-type accessibility indicators (for both regional and single point analysis)
• Regional analyses can handle grids with different extents
• Single point analysis now uses more consistent methods with regional analyses
• Routing engine fix for certain transfer times, specifically those from schedule-based routes to frequency-based routes.

August 2020

This backend release makes the following changes:

• Multi-dimensional regional analyses. Multiple travel time cutoffs, percentiles, and opportunity datasets can be chosen for a single regional analysis, which can greatly reduce repetitive tasks and waiting time.
• Considers additional OSM nodes and ways for park-and-ride access.
• Fixes a bug, present since before routing engine v3, that did not consider boarding a single essentially arbitrary route when transferring. On rare occasions where that route was relevant to the path being constructed, a suboptimal path would replace an optimal one, potentially altering travel time distributions enough to affect the selected percentile. Based on our testing, the impact appears to be limited in most cases to travel time discrepancies of a few minutes, for origin-destination pairs scattered throughout a region.
