Parkway tolls are a strong candidate for non-stop electronic collection, since Parkway toll plazas straddle the highway itself, unlike the NJ Turnpike where they are mostly concentrated at highway entrances.

A Parkway spokesperson told reporters that the Parkway was now gathering data from agencies that have implemented or are working on high-speed toll lanes. The Illinois State Toll Highway Authority, for instance, has retrofitted a number of toll plazas with express lanes that permit cars with a transponder to pass at 55 mph while still paying a toll.

The legislation would require the Parkway to introduce full-speed toll lanes at any plaza where E-ZPass customers are providing two-thirds of its revenue.

The lawmakers said they had concluded that the E-ZPass plan was more workable than their plan to eliminate most toll plazas but hike toll rates at the remaining ones.

The Tri-State Transportation Campaign discussed E-Z Pass' full-speed collection potentials with the legislators following release of their initial proposal.
