In many highway construction or reconstruction projects, an important decision regards the number of lanes to be provided. During the past three decades, conventional highway sizing procedures have remained virtually unchanged. During this same period, other highway decision-making processes have changed markedly as emphasis has highlighted broad social concerns and environmental impacts and as competition for the public dollar has intensified. In view of this situation, it is appropriate to reexamine conventional sizing procedures. The project reported herein was initiated to determine if wise and defensible investment decisions are being made regarding lane requirements and to identify, if necessary, possible techniques for improvement.
