Remedies for tollbooth trauma.

Next to radar traps and malevolent tractor-trailer drivers, nothing strikes more frustration in the hearts of motorists than crowded toll plazas. Fortunately, both technology and hope spring eternal: A new study shows that relatively minor changes in toll-plaza design can dramatically decrease congestion.

In a presentation at the Transportation Research Board meeting, Mitsuru Saito of the Institute for Transportation Systems at the City College of New York discussed two increasingly popular methods of alleviating toll-plaza congestion.

In electronic toll collection (ETC), motorists keep a magnetic debit card on their dashboards. Sensing equipment in the tollbooth extracts a tithe automatically from a prearranged account as the car passes. "You don't have to stop -- that's the key point," says Saito.

Toll-plaza managers can also build "branch tollbooths:' a set of additional booths beyond the main toll barrier and fed by lanes passing through it. These increase the capacity of the plaza without widening the facility -- an option often unavailable in heavily developed urban settings.

Based on previous surveys of congested toll plazas and direct observations of several plazas on New Jersey's Garden State Parkway, Saito developed a computer simulation to test various configurations of ETC and branch tollbooths. The results suggest that at plazas in and around New York City, where per-car delays sometimes mount to 25 minutes, ETC and branch toll lanes work best together. "Branch tollbooths can reduce congestion to a certain level:' Saito says. "If you want to reduce delay to 10 to 15 seconds pervehicle, then you need ETC as well as branch tollbooths."
