Explanation
Street Level Routing is a feature that calculates travel time between service appointments based on actual road distance and traffic conditions[131]. Default Travel 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 Operating Hour 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 time for 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 is a 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:

Explanation
This option allows viewing the asset relationships on the Asset object, where the primary asset is the parent asset and the related assets are the child assets. References:

Explanation
Match Boolean is an optimization criterion that prioritizes matching service appointments with resources based on boolean fields such as certifications or preferences[139]. Using Match Boolean in the Scheduling Policy would allow Universal Containers to ensure that Service Appointments are only assigned to Active Resources by creating a boolean field on the service resource object such as Active Resource and setting it to true or false depending on their status. Match Fields is an optimization criterion that prioritizes matching service appointments with resources based on fields such as skills or territories[140]. Preferred Resources is an optimization criterion that prioritizes assigning service appointments to resources who have previously completed similar work orders or who are preferred by customers[141]. Required Resources is an optimization criterion that prioritizes assigning service appointments to resources who are explicitly required by customers or dispatchers[142]. References:
