Is there a limit on how big my analysis can be?

Although there is no quantifiable measure of how big an analysis can be, our systems have an analysis runtime limit of 6 hours. If your runtime exceeds 6 hours, you may not receive an output. There are also size limits on arrays, you may have an error if you run an analysis with too many Zones. The number of days included in the analysis depends on the number of allowed O/D pairs changes. See the table below to understand the limits.
Note:

An analysis cannot include more than 366 days or more than 3500 Origins, Destinations, or Custom Zones.
