Samenvatting
The tri-state transportation commissions work program is unique among urban studies because it measures and describes both local and intercity freight traffic by all modes. Good estimates were obtained of the regions total traffic flow by mode. The objective now is to measure and describe each modes traffic and the characteristics of the freight-carrying portion of the system to develop a base for future projection by determining the freight requirements of the regions presint activities and by using forecasts of those activities. Future freight demands can then be forecast using trend analysis and it is possible to estimate each modes future share of traffic by broad commodity category.
