CPL Transportation Mode Selection & Routing 3 — Questions and Answers
Question 1: Which transportation mode is best suited for bulk shipments of grain moving from the Midwest to Gulf Coast export terminals?
- Truckload motor carrier
- Air cargo
- Inland waterway barge (Correct answer)
- Expedited parcel service
Correct answer: Inland waterway barge
Inland waterway barges are ideal for bulk agricultural commodities like grain moving to Gulf Coast ports, offering the lowest cost per ton-mile for high-volume, non-time-sensitive cargo.
Question 2: When evaluating transportation modes using the Total Cost of Ownership (TCO) approach, which cost element is often overlooked?
- Freight charges
- Fuel surcharges
- Inventory carrying costs during transit (Correct answer)
- Insurance premiums
Correct answer: Inventory carrying costs during transit
Inventory carrying costs during transit (in-transit inventory) are often overlooked but are significant, as slower modes tie up capital in goods while they move.
Question 3: A logistics manager wants to reduce carbon emissions while maintaining reasonable transit times for cross-country shipments. Which mode shift is most impactful?
- Switch from LTL to parcel
- Switch from truckload to intermodal rail (Correct answer)
- Switch from air to ocean
- Switch from pipeline to truck
Correct answer: Switch from truckload to intermodal rail
Shifting from truckload to intermodal rail can reduce carbon emissions by 75% or more per ton-mile while maintaining acceptable transit times for most domestic freight.
Question 4: What does 'freight equalization' mean in transportation pricing?
- Charging all customers the same freight rate regardless of distance
- Absorbing freight costs to match a competitor's delivered price (Correct answer)
- Dividing freight costs equally among multiple shippers
- Setting rates based on commodity weight only
Correct answer: Absorbing freight costs to match a competitor's delivered price
Freight equalization is a pricing strategy where a seller absorbs some or all freight costs to offer buyers a delivered price equal to that of a competitor located closer to the buyer.
Question 5: In multimodal transportation planning, what is a 'ramp-to-ramp' service?
- A truck service between two loading docks
- An intermodal service measured between rail terminals, excluding drayage (Correct answer)
- A ferry service between two port ramps
- A warehouse transfer between two loading bays
Correct answer: An intermodal service measured between rail terminals, excluding drayage
Ramp-to-ramp service refers to the rail portion of an intermodal move, measured between origin and destination rail terminals, excluding the truck drayage segments.
Question 6: Which routing strategy minimizes total distance traveled when a vehicle must visit multiple delivery points and return to its origin?
- LIFO routing
- Traveling Salesman Problem (TSP) optimization (Correct answer)
- Hub-and-spoke routing
- Cross-docking
Correct answer: Traveling Salesman Problem (TSP) optimization
The Traveling Salesman Problem (TSP) optimization finds the shortest route visiting all required stops and returning to the origin, minimizing total distance traveled.
Question 7: What is the primary advantage of a 'hub-and-spoke' distribution network over a 'point-to-point' network?
- Faster delivery times for all shipments
- Fewer total vehicle miles and lower cost through consolidation (Correct answer)
- Greater reliability due to fewer transfer points
- Easier tracking and visibility
Correct answer: Fewer total vehicle miles and lower cost through consolidation
Hub-and-spoke networks consolidate shipments at central hubs, enabling fuller loads on trunk routes and reducing total vehicle miles compared to direct point-to-point service for all pairs.
