Seasonal Variation in the Environmental Effects of Toll Collection. Evidence from the Garden State Parkway

Previous studies have shown that electronic toll collection (ETC) can have a positive impact on air quality compared with manual toll collection. However, many toll collection systems are subject to seasonal fluctuations in demand. As a result, the percentage of road users taking advantage of ETC changes throughout the year. Any decrease in the ETC participation rate will increase the amount of pollution created. This article quantifies the pollution effects of this seasonality. The authors use the Garden State Parkway (GSP) in New Jersey as a case study. Because of seasonal changes in ETC participation rates, they find that the quantity of pollution created by toll collection on the GSP increases significantly during the summer months. This seasonal change is caused by travel to the resort areas of the Jersey shore in the summer months. Unfortunately, the reduction in the efficiency of the ETC system occurs during the months when pollution abatement is most needed. These findings suggest that policy makers should take action to encourage ETC as a means of minimizing pollution. These measures could include lowering the cost of attaining a transponder or standardizing technology so that causal users from one area could use the transponder from their home region.
