Abstract
Consideration of the excess user costs of traffic delays caused by the presence of work zones is essential for assessment of impact of the work zones on the public. The excess user costs include traffic delay costs and additional vehicle operating costs resulting from speed changes at work zones. User costs at highway work zones are increasingly used by highway agencies to determine the contract times of highway construction projects. This paper analyzes the user costs at freeway work zones based on traffic data recorded by weigh-in-motion devices in Indiana. With a high traffic volume, user costs caused by a work zone can be significant; it is therefore desirable to minimize the user costs by expediting construction process. User costs at work zones are often used as the basis of determination of the monetary values for incentive or disincentive clauses in highway contracts for early or late completions of highway construction projects. In this study, the user costs at freeway work zones were computed based on the estimated traffic delays with the weigh-in-motion recorded traffic data.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
