Straight line distance vs road distance: why the map pin matters
A rail line, a river or a gated layout can turn a short straight line into a long drive. How to see the difference before you visit.

Two numbers that look the same
Straight line distance is the gap between two pins. Road distance is the length of the route a car actually drives. In cities with rivers, rail lines, lakes and walled campuses, the two can be far apart.
Where the gap comes from
Crossings are the usual cause. If the nearest bridge, underpass or level crossing is a few kilometres away, the route goes there first. Gated layouts add another detour when the only exit faces away from your destination.
How to check it
Put the home's gate and your office entrance on a map and ask for driving directions. Compare that distance with the one in the ad. Then time the drive at your hour; the time is the number that matters.
How a report handles it
Imperibuild starts every trip from the gate you confirm on the map, and flags any claim that uses straight line distance before measuring the road route.
