s to track loads combined into a larger container. To minimize handling-expense, damage and waste of vehicle capacity, optimal-sized pallets are often constructed at distribution points to go to particular destinations. A good load-tracking system will help deliver more than 95% of its loads via truck, on planned schedules. If a truck gets off its route, or is delayed, the truck can be diverted to a better route, or urgent loads that are likely to be late can be diverted to

logic to predict and improve arrival times. The exact means of combining these are usually secret recipes deeply hidden in the software. The basic scheme is that hypothetical routes are constructed by combining road segments, and then poor ones are eliminated using linear programming. The controlled routes allow a truck to avoid heavy traffic caused by rush-hour, accidents or road-work. Increasingly, governments are providing digital notification when roadways are known to have reduced capacity. A good system lets the computer, dispatcher and driver collaborate on finding a good route, or a method to move the load. One special value is that the computer can automatically eliminate routes over roads that cannot take the weight of the truck, or that have overhead obstructions. Usually, the drivers log into the system. The system helps remind a driver to rest. Rested drivers operate the truck more skillfully and safely. When these systems were first introduced, some drivers resisted them, viewing them as a way for management to spy on the driver. A well-managed intelligent transportation system provides drivers with huge amounts of help. It gives them a view of their own load and the network of roadways.
