TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 10: Alternative Truck and Bus Inspection Strategies explores the characteristics of the various types of alternative commercial truck and bus inspection strategies currently being used by law enforcement agencies. The synthesis examines how vehicles are selected for inspection; how, when, and where vehicles are inspected; and the consequences of violations. The synthesis also provides information on the effectiveness of the inspection strategies, documenting benefits such as reduced costs and improved resource allocation.

The objective of this report is to identify known relationships between commercial vehicle safety and crash causation factors and to prepare a synthesis of safety implications of oversize/overweight (OS/OW) commercial vehicles. This information can be used to support commercial vehicle enforcement and permitting practices and justify expenditures and investments on size and weight enforcement to enhance safety. In producing this report, insight was gained into the impacts of truck size and weight (TSW) regulations through three case studies. The state of practice in estimating large truck crash rates is complicated because of the many configurations and the wide range of possible weights for any particular configuration. This report highlights four primary findings regarding the contributions of OS/OW to commercial vehicle crashes found by its researchers.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 314: Strategies for Managing Increasing Truck Traffic documents recent efforts by transportation organizations that construct, operate, and manage the transportation system and identifies truck-related challenges, planning activities for goods movement being undertaken, truck management strategies being considered, factors that have influenced the selection of particular strategies, and benefits expected from selected strategies.
