Book Description
Construction zones can greatly affect the traffic flow on roadways, especially when lane closures are required. Traditionally, the Utah Department of Transportation (UDOT) has used traffic management specifications that only allow lane closures and road work to be done during predetermined hours or specifications that require a certain number of lanes to be open at all times. Recently, mobility-based work-zone traffic flow maintenance has been considered. This method requires continuous monitoring of mobility-based performance data and a mechanism to send alerts to the contractors when the mobility data does not meet the standards set by the specifications. UDOT recently tested mobility-based performance specifications at an urban arterial work zone and studied issues related to implementation of mobility-based performance specifications. Parallel to this experiment, UDOT funded a study to develop guidelines for implementing mobility-based performance specifications to manage traffic flow in work zones. Dynamically collecting mobility-based data such as travel time and speed is now feasible using technologies such as Bluetooth and microwave sensors. The core benefit of using mobility-based performance specifications is that they can give the contractor more flexibility in construction work scheduling while maintaining an acceptable level of traffic flow. If the level of traffic flow is not maintained, then the contractor is assessed a financial penalty. The penalty is determined by the amount of time where the flow is not maintained at a predetermined condition. To discuss issues and develop guidelines, a task force consisting of UDOT representatives, several representatives from the construction industry, and researchers from Brigham Young University was formed. Through three task force meetings, a set of 12 guidelines were developed, including guidelines about when mobility-based performance specifications should be used and which mobility data should be used. Some of the issues were difficult for the task force members to agree on, and a decision-making theory called the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was used to find best approaches to deal with some of the difficult issues associated with the implementation of mobility-based performance specifications in highway construction contracts. These guidelines should be reviewed as appropriate in the future as UDOT accumulates experience in using these types of specifications.

Book Description
UDOT funded a study to develop guidelines for implementing mobility-based performance specifications to manage traffic flow in work zones. The core idea of using mobility-based performance specifications is that they can give the contractor more flexibility in construction work scheduling and maintaining an acceptable level of traffic flow. If the level of traffic flow is not maintained, the contractor is assessed a financial penalty. This is the basic concept of mobility-based performance specifications. The penalty is determined by the amount of time where the flow is not maintained at a predetermined condition.

Book Description
This synthesis will be of interest to administrators, including contract and specifications administrators; research, construction, materials, specification, and design engineers; agency project managers and staff; and highway construction contractors. It describes the state of the practice with respect to the development and present status of performance-related specifications (PRS) for highway materials and construction. This report of the Transportation Research Board summarizes the historical events that have prompted U.S. interest in PRS development and describes the underlying concepts. In addition, it describes current practice with regard to PRS implementation and refers to the principal PRS literature with emphasis on performance and cost models. It emphasizes the utility of PRS in providing objective/ rational measures that can be used for special contract conditions, such as incentive or disincentive adjustments.

Book Description
"The majority of specifications used by state departments of transportation (DOTs) attempt to describe how a construction contractor should conduct certain operations using minimum standards of equipment and materials. These prescriptive specifications, commonly known as method specifications, have generally worked well in the past. However, with changes in the technology and the emphasis on providing more rapid solutions, more innovative specifications may be required in the future. Performance specifications can be used as a communication tool that translates the owner's performance requirements into language that will allow the contracting industry to understand, plan, and build the project to meet the requirements. Over the past decades many transportation agencies have experienced workforce reductions, thus diminishing the level of experience and number of engineers and inspectors. These demands have caused some agencies to experiment with the use of performance specifications in an effort to meet both the initial quality and long-term durability needs of the constructed products. Performance specifications have been used successfully on a project-by-project basis, but a general framework is needed to help agencies use performance specifications systematically. This report and the associated materials provide a framework that state DOTs can use to develop performance specifications; they include sample specifications language and implementation guidelines for both managers and specification writers."--Foreword.

Book Description
Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 455: Alternative Technical Concepts for Contract Delivery Methods Transportation documents various methods by which agencies have successfully implemented alternative technical concepts (ATCs) during the highway contracting process. The report identifies methods that promote transparency and fairness, while at the same time protecting the industry's right to confidentiality. The U.S. Federal Highway Administration defines an ATC as "a request by a proposer to modify a contract requirement, specifically for that proposer's use in gaining competitive benefit during the bidding or proposal process ... [and] must provide a solution that is equal to or better than the owner's base design requirements in the invitation for bid or request for proposal document."--Publisher's note.
