Truck Characteristics for Use in Highway Design and Operation. Volume I: Research Report

DTFH61-87-C-00088Highway geometric design and traffic operations are based in part on consideration of vehicle characteristics. However, many of the current highway design and operational criteria are based on passenger car characteristics, even though truck characteristics may be more critical. This report reviews existing data for the truck characteristics that need to be considered in highway design, including truck dimensions, braking distance, driver eye height, acceleration capabilities, speed-maintenance capabilities on grades, turning radius and offtracking characteristics, suspension characteristics, and rollover threshold. The report also includes these truck characteristics. The highway design and operational criteria evaluated include sight distances, vertical curve length, intersection design, critical length of grade, lane width, horizontal curve design, vehicle change intervals at traffic signals, sign placement, and highway capacity. An assessment has been made of the need to change the current highway design and operational criteria to accommodate trucks. The cost effectiveness of proposed changes in design and operational criteria has been evaluated. This volume, Volume I, of the report presents the main findings of the study including recommended changes in highway geometric design and operational criteria to accommodate trucks. Volume II of the report contains appendixes documenting the detailed data collection and analysis activities

ROADWAY WIDENING COSTS FOR GEOMETRIC DESIGN IMPROVEMENTS TO ACCOMMODATE POTENTIAL LARGER TRUCKS

The substantial costs that could be required to accommodate potential future trucks on the existing roadway system are estimated. These costs have been shown to be sensitive to the size of the truck and the extent of the roadway system considered. Geometric requirements are considered for truck configurations that have greater offtracking and swept-path width than tractor-semitrailer combinations with a single 14.6-m (48-ft) trailer (longer combination vehicles). The truck configurations evaluated include larger tractor-semitrailers, Rocky Mountain doubles, B-train doubles, turnpike doubles, and triples. The extent and cost of roadway widening that would be necessary to accommodate the larger trucks are considered for horizontal curves on mainline roadways and interchange ramps and for ramp terminals and at-grade intersections. Potential costs also are included to provide staging areas to accommodate larger multi-trailer trucks and the cost savings in geometric improvements that might be required if staging areas were provided. Tables illustrate both the estimated extent of geometric design improvements and the cost of those improvements to accommodate particular truck configurations on particular roadway networks. These costs have been estimated for truck configurations that are larger than the 14.6-m (48-ft) tractor-semitrailer combination that was used as the baseline vehicle for the study
