By 9:15, two customers have called to reschedule, one loading dock is blocked by a delivery that arrived late, and a driver is circling a downtown block because the address has no legal curb space for a box truck. The route on the screen looked efficient at 6 a.m. By mid-morning it is fiction. Distance math never survives contact with a real street. That gap between the plan and the day is where money leaks. Fuel is the line item most fleet managers watch, and in dense urban delivery it can consume a large share of operating expenses once idling, rerouting, and failed delivery attempts are counted. The full cost breakdown, including the second-attempt trips that never show up in a routing score, is worth studying in this analysis of last-mile delivery cost. Distance is only one variable. Three others decide whether a route holds up: * **Capacity.** A van that is 90% full cannot absorb a same-day order without a second trip, and a second trip erases the savings the optimizer promised. * **Curb and parking access.** A stop with no loading zone takes 8 minutes longer than the routing engine assumes. Multiply that across a dense commercial corridor. * **Real-time disruption.** Road closures, no-access windows, and customer cancellations arrive mid-shift. A route that cannot be resequenced in minutes is a route that gets abandoned. Most routing guides optimize the first variable and ignore the other three. That is why the savings look impressive in a demo and modest in a monthly P&L. The fix is not a better algorithm alone. It is feeding the optimizer the constraints that really stop drivers: vehicle height and weight limits, time-window rules, dock availability, and parking legality by block. When those inputs are accurate, resequencing a disrupted route becomes a two-minute task instead of a phone call to every driver. Get the constraints right and the distance savings follow. Get them wrong and the best route on paper is the one your drivers ignore by 9:30. [← Back to all posts](https://routelink.app/blog)
