["The report explores how toll roads and public-private partnership contracts and legislation could promote environmental stewardship and equity. If public-private partnership road projects apply tolls only to new lanes and use toll revenues only to build more roads, they will tend to exacerbate environmental and equity problems; however, if tolls are used to manage both new and existing lanes for higher performance and to fund public transit and impact mitigation, equity and the environment can benefit greatly."
