Effect of Freeway Work Zones on Fuel Consumption
The objective of this study was to investigate the effect of freeway work zones on fuel consumption. The development of a procedure for estimating the excess fuel consumption caused by lane closures … [Read more...] about Effect of Freeway Work Zones on Fuel Consumption
Adding up Motorist Costs
It happens all too frequently, sitting in idle cars waiting for traffic to thin or making long detours because of road construction. Motorists often call it frustrating - transportation officials have … [Read more...] about Adding up Motorist Costs
Techniques for Manually Estimating Road User Costs Associated with Construction Projects
The objectives of this research study are: 1) to develop a manual technique for determining RUC for typical added-capacity and highway rehabilitation projects; 2) to develop implementation guidelines … [Read more...] about Techniques for Manually Estimating Road User Costs Associated with Construction Projects
Strategic Work-Zone Analysis Tools
The Strategic Workzone Analysis Tools (SWAT) program is a new FHWA initiative. Four tools are being developed as part of the initiative: an Expert System software program, a traffic impact analysis … [Read more...] about Strategic Work-Zone Analysis Tools
Emissions Due to Construction Equipment and Traffic Delays – Task 6: Contribution of Vehicular Emissions Caused by Reduction in Capacity During Roadway Construction
Task 6 modeled an array of possible construction work zone projects with respect to facility demand (low, medium, and high average annual daily traffic [AADT]); facility cross section (two to five … [Read more...] about Emissions Due to Construction Equipment and Traffic Delays – Task 6: Contribution of Vehicular Emissions Caused by Reduction in Capacity During Roadway Construction
