Service Territories are used to group resources and service appointments based on geographic areas or other criteria. The recommended limit for service appointments per territory per day is 500 for optimal performance and user experience.

Street Level Routing is a feature that calculates travel time between service appointments based on actual road distance and traffic conditions[131]. DefaultTravel Speed is a setting that defines the average speed of resources when traveling between service appointments[132]. Using Street Level Routing and Default Travel Speed would allow improving travel time accuracy by taking into account real-time road conditions and resource speed. Minimum Grade, Default Operating Hour would not affect travel time accuracy. Minimum Grade is a setting that defines the minimum skill level required for resources to be matched with service appointments[133]. Default OperatingHour is a record that defines the default working hours for resources
[134]. Estimated Travel Time, Minimize Travel would not affect travel time accuracy. Estimated Travel Time is a field on the service appointment object that shows the expected travel timefor the assigned resource[135].
Minimize Travel is an optimization criterion that prioritizes reducing travel time when scheduling service appointments[136]. Travel Speed Unit, Actual Travel Time would not affect travel time accuracy. Travel Speed Unit isa setting that defines the unit of measurement for travel speed such as miles per hour or kilometers per hour[137]. Actual Travel Time is a field on the service appointment object that shows the actual travel time recorded by the resource[138]. References: https://help.salesforce.com/s/articleView?id=sf.
