Pressures to develop transportation projects that are biddable, buildable, and maintainable may be greater today than ever before. As a result, many transportation agencies are concerned about the constructability and quality of design documents for roadway facilities. The Washington State Department of Transportation has performed a research study to develop a constructability review process (CRP) to improve the constructability of its projects. The CRP is composed of constructability reviews at various prescribed points in the project time line. The reviews incorporate constructability checklists and planned meetings among all of the disciplines involved. Implementation of the CRP is expected to reduce the number of construction change orders, the total cost of change orders, construction and maintenance staff, and the amount of resources and to lead to a “zero addendum” bid phase.

Computer Based

The purpose of the Transportation Economic and Land Use System (TELUS) is to convert the transportation improvement program (TIP) into a management tool. Accordingly, the system provides detailed and easily accessible information on transportation projects in the region, as well as their interrelationships and impacts. By doing so, TELUS enables public-sector agencies to meet organizational, Intermodal Surface Transportation Efficiency Act, state, and other mandates more effectively. The objectives are accomplished by providing the computer-based capability to analyze, sort, combine, and track transportation projects in or under consideration for a TIP; assessing the interrelationships among significant transportation projects; estimating the regional economic and land use effects of transportation projects; and presenting project information in an easily understood format, including geographic information system formats.

Lock In

AbstractLock-in is defined as the tendency to continue with an inefficient decision or project proposal. The front-end phase is critical to project success, yet most studies have focused on lock-in in the implementation phase. Moreover, little is known about the way in which decision-makers perceive the risk of lock-in. In this paper we identify determinants of lock-in in the front-end phase and we reveal decision-makers’ perceptions of risk of lock-in. Our findings show that risk attitudes towards lock-in vary with the level of risk aversion. However, this is not sufficiently acute to drive the level of regret needed to avoid lock-in. This implies that decision-makers do not accurately assess the risk of lock-in and as such their risk perceptions are a mediating factor in the formation of lock-in. Based on escalation of commitment, path dependency, and prospect theory, the main contribution lies in providing a more comprehensive understanding of lock-in in the front-end phase.

The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires the integration of environmental considerations into transportation planning. Although previous legislation has required the consideration of environmental elements during project planning, ISTEA necessitates a different approach. During project-specific planning, each environmental element is researched to determine baseline conditions, and project plans are superimposed to determine potential impacts and the need for mitigative measures. This approach is appropriate for project-specific planning, but it presents only a snapshot of existing conditions because environmental data are changing constantly. The integration of environmental considerations into long-range plans requires a much broader focus. It must allow dynamic systems to change without affecting the plan's validity. A case study is presented of the Oklahoma statewide intermodal transportation plan, which uses recent geographic theory to integrate planning and human activity at varying scales. This theoretical framework is based on ecological and societal units of interaction called bioregions or place-systems. The environmental baseline and analysis for Oklahoma begin with the identification of place-systems in the state: areas of biophysical and cultural similarity and context. The delimitation of such regional place-systems is sufficiently generalized and flexible to accommodate many data types and sources, yet rigid enough to be useful for planning. Both quantitative data and descriptive information are included in an analytical framework suitable to relational data bases and geographic information systems applications. These are used to create a series of map and data overlays to project potential environmental impacts and constraints, as well as opportunities for developing future transportation projects. The methods used to delineate regional place-systems in Oklahoma and their subsequent use in environmental analyses and planning are described.
