Expanded Transportation Performance Measures to Supplement Level of Service (LOS) for Growth Management and Transportation Impact Analysis.

摘要

Growth management has attempted to manage the pace of development while providing or improving transportation services to users. However, these efforts have largely focused on automobile travelers using as a primary evaluation tool for growth management the Level of Service (LOS) designations. Continuing this vehicular focus is no longer feasible due to increased right-of-way costs, limite public and private funding, and the shrinking returns associated with vehicle-oriented infrastructure improvements. Many jurisdictions in Florida are moving toward multimodal transportation systems that provide users with viable travel options in an effort to minimize the economic, social and environmental costs that have been associated with a purely vehicular system. To support this transition, a set of performance measures is needed that will supplement the vehicle-based LOS and will help agencies assess new development and land use changes from a multimodal perspective. This project first identifies an extensive list of performance measures from the existing literature. These measures are categorized by type into 5 major categories: infrastructure and environment, system utilization, user perception, safety, and sustainability. Infrastructure and environment measures focus on the Four Ds of land use and the built environment: density, diversity, design, and destination Accessibility.
