Book Description
On-site construction activities can result in significant mobility and safety impacts to road users. The presence of work zone can also result in inconvenience to local business and community, noise and environmental impacts. Minimizing the adverse impacts of work zones has become a higher priority especially since the inception of the FHWA Rule on Work Zone Safety and Mobility (23 CFR 630 Subpart J). Work zone road user costs (WZ RUC) provide the economic basis for quantifying these adverse impacts which can then be used for effective decision-making to improve work zone mobility and safety. This report provides practitioners with information on WZ RUC analysis concepts and their applications using case studies drawn from real world projects. WZ RUC primarily refers to monetized components of mobility and safety impacts; increasingly, non-monetary and qualitative components, such as environmental, business, and societal impacts, are being utilized. In this report, each of the monetary components is explored and the computations of these components are illustrated using examples. It presents step-by-step procedures to derive unit costs for monetary components. It lists the cost sources for each cost component as well as the ways to update those using economic indices. It also explores input requirements and various tools available for use in WZ RUC analysis. This report presents the application of both monetary and qualitative components of WZ RUC in MOT alternative analysis using a decision analysis framework. Another key application of WZ RUC is in selecting appropriate project delivery/contracting strategies to minimize WZ RUCs and related impacts through early project completion. Approaches for determining an appropriate level of incentives and disincentives are also discussed. Three “real-world” case studies from the Highways for LIFE program are presented to demonstrate the applications of WZ RUCs in selecting the preferred Maintenance of Traffic (MOT) alternatives and project delivery/contracting strategies.

Book Description
This report defines a work zone, its capacity, and how it is estimated. The importance of capacity is also mentioned since it is directly used in the calculation of user delay due to a work zone. The impact of delay on user costs is also discussed. A methodology is presented which relates queue delay with ADT. Queue delay due to a work zone is calculated using a plot between time, cumulative volume, and capacity. The area between the curves represents queue delay. Three software packages are evaluated for calculation of user delay and cost due to a work zone. None of them were adequate for calculating delay due to queue formation.

Book Description
This research was developed to produce usable and meaningful estimates for work zone capacities under a variety of roadway and traffic conditions, work zone configurations, and lane closure scenarios within Texas. Using data collected at eighteen work zone sites, the research presents updated guidance for expected capacities of various freeway work zone lane closure configurations. In addition, models used to evaluate traffic conditions in work zones were evaluated and recommendations for their use were made. Finally, recommendations concerning road user cost analysis for freeway construction projects are included.

Book Description
This synthesis will be of interest to state department of transportation (DOT) administrators and mid- to upper-level managers; researchers; cost estimators; bridge and general management system engineers; and bridge design, construction, inspection and maintenance engineers; as well as to private industry professionals involved in developing bridge management system (BMS) software and collecting and analyzing BMS cost data. The state of the practice for collecting and managing cost data for BMS is described based on data obtained from a review of the literature and a survey of the state DOTs. This report describes BMS cost data for work done by contract and in-house forces for state and local governments. It includes project-level cost estimation as well as the collection and management of data for network- level cost models. The various cost estimate methods for replacement; maintenance, repair and rehabilitation; and emergency work are analyzed as are the special requirements of user costs and other special economic data.
