| 摘要： | The Washington State Department of Transportation (WSDOT) is one of the nation’s leaders in calculating and using reliability statistics for urban freeways. The Department currently uses reliability measures for decision making for urban freeways—where it has applicable data—and as input to analyses that are part of major investment studies and other project identification and prioritization studies. The project documented in this report is intended to provide WSDOT with an online data analytic system that is capable of producing a variety of roadway performance measures specifically oriented toward identifying bottlenecks, and of determining the size, timing, and scope of delays those bottlenecks impose on travelers and freight shipments. The data used to determine the size of delays are also to be accessible as inputs to tools designed to evaluate alternative strategies for improving roadway performance. The system, Digital Roadway Interactive Visualization and Evaluation Network (DRIVE Net), which continues to be developed at the STAR (Smart Transportation Applications and Research) Lab, is designed to integrate data from multiple, siloed data sets. It is intended to create key inputs for WSDOT’s planning and project selection process, as well as supply inputs to other analytical tools used in the planning and programming processes. |
