Why does it confuse you to have different terms appear in the same
sentence? Almost all sentences involve more than one term.

Take any measure of congestion (e.g., total traffic delays, the
difference between the normal time that trips would take with no other
traffic, and the time that they take in actual conditions). That's just
a number. If you don't vary anything else (e.g., the population of the
area does not change), and you build some new highways or expand some
existing highways, then that number might go up or it might go down.
Some projects do make it go up, for the reasons that I described. Even
though they do increase the carrying capacity of the particular stretch
of road involved.
