Road construction traffic delays are not only frustrating, they can be costly to motorists in terms of lost time and wasted fuel. To minimize motorist inconvenience and road user cost, the Texas Department of Transportation (TxDOT) offers contractors bonuses for early completion and charges them liquidated damages for late completion. That makes calculating road user cost as an incentive or disincentive amount an important factor in TxDOT contracting activities. Researchers have investigated various estimation techniques and cost components and, focusing on motorist time costs, developed a simplified approach to calculating road user cost values. The new approach uses a series of look-up tables that gives road user cost values based on project type and limited attributes. |
