| 摘要： | Under the Virginia Transportation Act signed into law in April 2000, more than $10 billion would have been invested in highway construction, public transportation, airports, and ports during the following 6 years. However, recent budgetary constraints will result in a delay in investing more than $2 billion in road projects for more than a decade. In the current study, a previously developed comparison tool was extended to bring quantitative evidence of safety and categorical evidence of broad motivations to planners, engineers, and the public in comparing the benefits of proposed transportation projects. The extended tool developed in the current study provides visual devices for presenting multifaceted information about project attributes. Policymakers and planners may find the presentation useful in assessing what types of projects are being undertaken and what projects to prefer to others. The extended tool represents project information including cost, average daily traffic, and crash rates for comparison and prioritization of the 1,500 candidate project that constitute the development plan of Virginia highways. The extended tool is flexible to accommodate application such as project selection (planning) and programming. Several sources of information include the crash databases of the Virginia Department of Transportation (VDOT) and project plans for districts and localities. The extended tool enables planners to identify principal motivations for various projects based on categories defined by the Transportation Equity Act for the 21st Century. The tool introduces summary reports of criteria including project aggregate costs and counts of projects with particular motivations, facilitating system-level analyses and project ranking. |
