6 Transportation Management
Learn how to select transportation modes and carriers, plan shipments, compare total logistics costs, and measure transportation performance.
goals
matches freight to suitable modes and carriers, plans feasible routes, and measures results. The central task is to balance cost, speed, reliability, capacity, safety, and cargo condition while meeting customer and regulatory requirements.
Choosing a transportation mode
Each transportation mode has different strengths, limitations, and infrastructure needs. The best fit depends on the product, shipment size, origin and destination, available services, required delivery time, and the cost of inventory tied up in transit.
Truck: Flexible and widely available, with direct door-to-door service suited to shorter or time-sensitive moves. Trucks also commonly handle pickup and delivery for other modes.
Rail: Often suited to large volumes and long distances, including bulk commodities and containerized freight. Service depends on rail networks and terminals.
Water: Moves large loads efficiently over waterways and oceans, but is generally slower and depends on port access and vessel schedules.
Air: Fast and useful for urgent, high-value, or perishable goods. It is typically costly and constrained by shipment size and airport access.
Pipeline: Moves suitable liquids and gases continuously between connected facilities, but offers little flexibility in route or commodity.
: Combines modes, often truck and rail or ship and land transport, while keeping freight in a container or trailer during transfers. It can combine the strengths of different modes, but adds transfer points and coordination needs.
A low freight rate is not necessarily the best choice. Slower or less predictable service may require more safety stock or increase the risk of damage or missed delivery. Mode decisions therefore need to account for service and inventory effects as well as the quoted transportation price.
Selecting carriers
A is a company that transports freight; a broker or logistics provider may arrange transportation with carriers. Select providers against the shipment’s requirements, not price alone.
Important selection criteria include:
Service fit: Equipment, geographic coverage, capacity, transit time, schedule, and ability to handle special cargo such as refrigerated or hazardous goods.
Reliability: Historical on-time performance, communication, tracking visibility, and plans to recover from disruptions.
Total cost: Freight charges, accessorial fees, fuel-related charges, handling, claims, and the costs of delays or extra inventory.
Safety and compliance: Applicable operating authority, insurance, safety history, and relevant permits.
Resilience: Backup capacity, alternate routes, and dependence on a single provider or corridor.
For U.S. motor carriers, FMCSA’s SAFER Company Snapshot provides identification, inspection and out-of-service summaries, crash information, and a safety rating when available. Treat these records as one input to due diligence. Reported crash involvement is not itself a finding of fault, and data should be interpreted in context.
and shipment planning
determines a shipment’s path and sequence of stops, and sometimes its mode or combination of modes. A practical planning process is:
Define the shipment: origin, destination, quantity, dimensions, weight, handling needs, and delivery window.
Identify feasible services and routes, including any required terminals or transfers.
Check constraints such as vehicle capacity, road or bridge restrictions, hours-of-service rules, facility hours, and customer appointments.
Compare feasible alternatives by cost, transit time, reliability, cargo risk, and emissions where relevant.
Monitor progress and adjust when delays, closures, or other disruptions occur.
For multiple deliveries, planners may sequence stops to reduce distance, time, and empty running while honoring capacity and delivery windows. Consolidating smaller shipments can reduce cost per unit, but may add waiting and handling time. A direct shipment may cost more but arrive sooner or involve fewer transfers. Route and mode choices therefore depend on both transportation and broader logistics costs.
Freight economics
Freight prices are only one part of the economic decision. can include line-haul charges, pickup and delivery, fuel-related charges, terminal handling, storage, inventory carrying cost, cargo loss or damage, and the cost of late or unreliable delivery. Shipment size, distance, commodity characteristics, and transfer requirements affect these costs.
Two useful comparisons are:
Freight cost per shipment:
:
These measures help compare alternatives, but neither captures every service or inventory consequence. A slower, lower-rate rail option may be economical for a steady, large-volume flow, while a smaller urgent shipment may justify the higher cost of truck or air service. The appropriate comparison includes the service level the customer needs.
Measuring transportation performance
Measure performance against explicit service goals and review it by , route, mode, and shipment type. Use consistent definitions and time periods.
: On-time deliveries divided by total deliveries, using a clearly defined delivery window.
Transit time and variability: Average time from pickup to delivery, together with how much it varies. Unpredictable travel times may require schedule buffers and can disrupt production or customer service.
Transportation cost: Cost per shipment, unit, ton, or ton-mile, interpreted alongside service and cargo requirements.
Damage and claims rate: Damaged or lost shipments divided by total shipments, or shipment value when appropriate.
Capacity and utilization: Available capacity used, load utilization, and empty miles where data are available.
A with a low average transit time may still perform poorly if delivery times vary widely. Likewise, a low cost per mile may conceal low vehicle utilization or high accessorial charges. Performance data should help identify root causes and guide corrective action, not merely rank providers.
Putting transportation decisions together
Effective matches freight to suitable modes and carriers, plans feasible routes, and evaluates decisions using rather than freight price alone. Regular performance measurement helps organizations improve service and respond to disruptions.
