Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.
Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.
Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.
When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.
The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.
