Study on the Relationship between the Traffic Characteristics and Speed at the Access of Urban Tunnels

Article Preview

Abstract:

The present work sought to extract and quantify the factors influencing the speed at the access of the urban tunnels by factor analysis method and then found out that the principle factors influencing operating speed were cart ratio, mean time headway, brightness difference between inside and outside of the cave. Finally through the SPSS statistics software and on the base of analysis of multi-line regression, the prediction model of operating speed was established.
