Samenvatting
The physical condition, performance, and costs of transportation infrastructure deteriorates over time due to aging and use. Reversing this decline is difficult because decision makers and technical professionals prefer to concentrate on new construction. While interest in, and resources for, reinvestment have expanded in the U.S., it is not apparent how these resources can be most efficientciently allocated. Evaluation of specific types of benefits of transportation reinvestment, using available planning tools, is suggested as both feasible and necessary.
