This is the Summary Report of Phase I of the Comprehensive Truck Size and Weight (TS&W) Study announced by the Federal Highway Administator in June 1994. It summarizes 13 working papers prepared during Phase I. The study is to be completed in three phases; Phase I--Synthesis of TS&W Studies and Issues--assessed past policy studies and technical research. Technical knowledge about relationships between TS&W policy controls and relevant evaluation and decision criteria was synthesized. State and Federal TS&W regulations were summarized. Research needs for later phases were identified. Thirteen working papers were prepared examining the regulatioins and TS&W policy controls and: truck accidents, vehicle stability and control, pavements, bridges, roadway geometry, traffic operations, truck costs, shipper logistics costs, truck travel and mode share, enforcement, environment, energy, permits and pricing mechanisms. Based on a review of the information, FHWA has identified several policy and technical issues for consideration in Phases II and III of the study. No policy conclusions were drawn in Phase I and none are discussed in this report. Consideration of policy options is being done in the later phases. This interim report is being issued at this time to gather wide input from both the public and private sectors on the issues of importance to this study. |
