Speed Index: Scalable Operations Performance Measure Based on Available Data

摘要: Given the increased emphasis on transportation system operations, agencies require effective operations performance measures. The purpose of present research effort was to develop and explore utility a simple measure that meets following criteria: (a) it is measurable given current sensor deployment, (b) understandable wide range individuals, (c) applicable different functional classes roadways, (d) scalable from lane level up regional or statewide measure, (e) independent major assumptions estimation techniques. proposed explored in this paper, speed index, can be defined as volume-weighted percentage limit at which roadway location, zone, corridor, even region operated for time period. This demonstrated supporting numerous analysis activities, including an seasonal variations traff...
