Transit Time
Definition
Transit time is the elapsed time between a shipment leaving its origin and arriving at its destination. It is a core component of total lead time and a key input to inventory and delivery planning.
In Practice
Every mode carries a characteristic transit range: parcel ground runs one to five days regionally, LTL two to five days, truckload often next-day within 800 miles, intermodal a few days longer, and international ocean two to six weeks port to port. Published transits are usually in business days and exclude pickup day, holidays, and terminal handling, details that matter when promising delivery dates.
Planners care about the variability as much as the average. A lane averaging 20 days with a standard deviation of 5 forces more safety stock than a 25-day lane that never varies, because buffers protect against the spread, not the mean. Measuring actual transit against carrier standards, by lane, is the basis for both carrier scorecards and realistic promise dates.
For example, a planner quoting availability adds ocean transit, port dwell, dray, and receiving time, then pads by the lane's observed variability before committing a date to sales.

OTIF measures the percentage of orders delivered both on the promised date and with the complete ordered quantity. An order must pass both tests to count, making OTIF a strict combined measure of delivery service.
Ocean FreightOcean freight is the transport of goods by sea, typically in standardized containers aboard container ships. It is the dominant mode for international trade, offering the lowest cost per unit at the price of long transit times.
Route OptimizationRoute optimization is the process of determining the most efficient sequence of stops and paths for delivery vehicles, minimizing distance, time, or cost while respecting constraints like time windows, vehicle capacity, and driver hours.
Intermodal TransportationIntermodal transportation moves freight using two or more modes, most commonly truck and rail, with the cargo staying in the same container or trailer throughout. Goods are transferred between modes without being unloaded and rehandled.
