By using two or more collection stations in the same traffic lane, tandem toll or parking-fee collection increases lane capacity and reduces the need for plaza widening. Data are presented relating processing rates to toll fee; e.g., the rate for a $1.25 fee is 30 percent slower than that for a $1.00 fee. Toll agencies that have implemented $1.25 tolls have encountered extreme congestion, especially with the weekend recreational traveler. Several operational configurations of tandem tolls are described. A coordination device is described to automate the control of motorist traffic signal and payment signal to distinguish between axle registrations of successive vehicles, even under dense conditions. Slow collection devices such as paper-money acceptors or flexible-ticket readers that are impractical at a conventional active lane are feasible in tandem. The expected capacity increase depends on the conventional cycle time, its standard deviation, and the distance between the toll stations. When the distance is several vehicle lengths, the stations are buffered, which results in better performance and independence of capacity increase on cycle time variance. The slower the existing collection time, the greater the capacity increase, e.g., 6 s/vehicle yields a 34 percent increase, 20 s/vehicle, 1.75 percent increase, when buffered. (Author)
