Engineers often work with logical operations.

Logic is critical to dynamic control. An excellent

example of this exists in transportation

engineering. Conditional logic operations are

needed to manage the complex track

schedules for light$-$rail transit $($LRT$)$ systems.

The following lab demonstrates input$/$output

control for an LRT system. The operational logic

of an LRT junction is to be implemented for

user$-$defined input with a C$++$ program.
