There are several types of routing functions available in Field Service Lightning, the default being ‘aerial routing’, used to estimate travel times. Aerial routing works by calculating the distance between two locations in a straight line, the accuracy of which can be improved with ‘street-level routing’ which provides an expected travel time based on road lengths and permitted speed. The use of the ‘predictive travel’ function enhances routing accuracy even further by accounting for the time of day and other affecting complications. These functions allow for minimised travel times and frustrations between appointments to keep workers in the loop and happy.
