ABSTRACT: Construction sites or work zones create serious disruptions in the normal flow of traffic resulting in major inconveniences for the traveling public. These traffic problems affect the motorists by considerably increasing their travel time because of delays, and even their travel distances in the case of forced detours. The speed changes and detours also impact the operating expenses of the vehicles. Furthermore, and most importantly, these work zones create safety hazards that require special consideration. Reducing construction time, and therefore reducing the amount of extra costs generated, has become a major issue for state highway agencies throughout the United States. Most of the innovative contracting practices for highway construction projects specifically address the reduction in construction time as a means to minimize the negative effect that road work areas have on the motorists and on the general public. Additionally, current legislation and programs, at both state and national levels, are continually emphasizing the need for a better understanding of work zone problems as a means to address the issue of work zone safety. This reality, coupled with the fact that every year more miles of highway are being temporarily closed for rehabilitation and maintenance purposes, makes the analysis of safety at construction sites a very serious matter. This research endeavor represents a comprehensive study of the different problems and variables associated with the development of a new practical approach to address the issue of highway safety in construction zones. Since empirical models require sample sizes which are rather unattainable due to the intrinsic scarcity of construction zone accident data, the problem was studied from the point of view of risk analysis. Monte Carlo simulations were used to develop risk factors. These factors are meant to be included in the calculations of additional user costs originated at work zones, in an effort to optimize length and duration of closures for highway reconstruction/rehabilitation projects. In this way, it will be possible to effectively assess the danger that work zones represent for the traveling public, and therefore, help to minimize their adverse effect on highway safety.

This report will be of interest to state and local highway agency construction managers and contractors with regard to learning about best practices of time-related incentive and disincentive contract provisions and their effect on staffing levels, productivity, project cost, quality, contract administration, and the contractor's operations and innovations. The report also presents a decision process guide to use as a template for crafting the incentive/disincentive provisions.

This synthesis report will be of interest to transportation agency planners; design, construction, and maintenance engineers; and administrators, managers, economists, and other decisionmakers involved in programming highway pavement projects. This synthesis describes current practice with regard to road user and mitigation costs in highway pavement projects. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search of both domestic and foreign publications. This report of the Transportation Research Board provides detailed information on the various methods employed by transportation agencies to estimate user costs. The advantages and disadvantages of each are reported. Information on the various components of user costs (that is, time related, vehicle operating, safety, and environmental costs) is also included. In addition, the study reports on the various mitigation strategies available to agencies to reduce user costs. Information is also provided on how user costs and mitigation strategies have been applied to evaluate different alternatives; and how uncertainties, political considerations, and quality control contribute to the decisionmaking process.

As freeway construction increases with the need to expand, repair and maintain the existing infrastructure, the desire to quantify the inconvenience or delay costs to the user of the freeway undergoing-construction has increased and become necessary to assist in determining total project impact costs and determine penalties or lane rentals to contractors. This paper will review critical variables which impact delay costs, delay avoidance strategies and various methods and models developed to quantifying these costs. Overall, the amount of research specifically in this area is limited as interest is just beginning to rise in quantifying these costs. However, numerous studies have been completed in the past in related areas which will be reviewed for their applicability to this project. State Departments of Transportation need to determine impact costs to develop freeway projects in the most cost effective manner. The methods used in project sequencing, scheduling, and work hours must provide the least impact to the traveling public without incurring excessive costs to the project. Businesses which rely on freeways to deliver their goods and services can be particularly impacted. The inability to deliver goods and services on time begins to have significant impacts in this era where - more companies are shifting to "just-in-time" delivery methods to reduce costs, particularly inventory storage costs. Companies with perishable goods are also at significant risk if these goods cannot be delivered to consumers with sufficient shelf live remaining. - Freeway users not involved in business are also impacted by construction delays. While these costs are much more difficult to quantify, the user definitely experiences frustration and a sense that time is being wasted while waiting to bypass constricted areas on the freeway.
