Abstract

We estimate reductions in vehicle emissions of carbon monoxide, nitrogen oxides, and hydrocarbons from highway congestion pricing in New Castle County (NCCo), Delaware. Our computer simulation model includes elastic travel demand with routes chosen to minimize average private cost (no pricing) or marginal social cost (congestion pricing) of all trips between pairs of 257 zones in NCCo. We model vehicle emissions using the EPA's Mobile 5a emissions model. Using Delaware's household travel-demand and highway traffic-count data, we simulate pricing all roadways and pricing only major highways. We estimate reductions of emissions from five to fifteen percent on major highways, depending on demand elasticity and extent of pricing.
