• New options for spatial datasets, such as calculating travel-time matrices for uploaded origin-destination pairs
• Allows using different sized destination layers in the same regional accessibility analysis
• Supports higher cutoffs with linear, exponential, and logistic decay functions
• Corrects a bug that affected adjust-speed modifications with specific segments selected
• Freeform (non-grid) pointsets can be used as origins and destinations in regional travel time and accessibility calculations.
• Improvement to how polygons with low opportunity densities are disaggregated into raster grids.

This release was made immediately after the v6.0.0 release to fix a bug in applying transfers. It should be used instead of v6.0.0.

• Unified R5 / Analysis Backend
• 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.

4.6.0 (2019-07-01)

AFFECTS RESULTS

When used in Conveyal Analysis, this version of the routing engine:

• Sets the default mode of newly created add-trip modifications to bus, instead of tram/streetcar.
• Resolves a bug that marked certain distant destinations (over 4h 15m away by walking or biking) as reachable in single-point analyses. This bug did not affect regional analyses or analyses with public transit enabled. In single-point analyses with transit disabled, past versions of the routing engine and front-end incorrectly considered destinations over 255 minutes away from an origin to be reachable, even at low travel times. As of v4.6.0, the routing engine correctly marks such destinations as unreachable, which may decrease some single-point accessibility results relative to past (erroneously) high results.
• Resolves a bug that altered the effective length of street segments when stops were linked to them. This fix may affect results in areas with sparse road networks, curving roads, and multiple public transit stops. In particular, relative to past versions of the routing engine, v4.6.0 may increase accessibility for origins around street segments that have numerous, far-away stops linked to them.
• Applies limits specified in the Advanced Settings for Max Walk Time and Max Bike Time. More details are available in the user manual. Past versions of the routing engine applied a 20 minute limit to access and egress legs. The default limits are still 20 minutes, so unless you edit these settings, results should not be affected. Introduces beta support for custom modifications representing congestion delays and pickup times for hailed rides (e.g. TNCs or autonomous vehicles). If you'd like to try these modifications, let us know.
