Characteristics Analysis and Model Application of Traffic Speed-Volume Relationship in Urban Elevated Roads

摘要

Based on survey data selected from detecting coils locating in Shanghai inner loop elevated roads, speed-volume relationship charts were plotted. Some characteristics were selectively analyzed in certain traffic and road conditions such as traffic speed-volume variety characteristics of different lanes in same road section and traffic speed-volume relationship comparison of same lane in different road sections. Finally, statistics models were built to do further study with application of these traffic characteristics. This study can provide reference for traffic design, management and control projects.
