Abstract
The Construction Congestion Cost System (CO3) is an integrated set of tools to estimate impact of traffic maintenance contract provisions on congestion, road user cost, and construction cost. CO3 produces realistic budgets and selects practical contracting methods that provide an acceptable balance between construction cost and congestion. This paper describes the underlying CO3 model of traffic demand, delay, and user cost, particularly the methods by which CO3 calculates traffic backup and delay, diverted and canceled trips, and road user cost. It provides examples that illustrate the CO3 model and methods. CO3 models the common characteristic of construction work zones by which road capacity can vary from hour to hour as lanes close and open and work conditions change. Traffic demand also varies with time of day, and drivers may divert to an alternate route or cancel trips because of delays caused by construction. CO3 estimates traffic delay due to traffic congestion as a function of demand and capacity, and it estimates traffic cancellations and diversions as functions of traffic delay.

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
