Analysis of Minimum Width of Central Partition Belt Based on Satisfying Basic Functions

Abstract

Essentials, JTG B01-2014 Technical Standard for Highway Engineering No longer specifies the recommended value for width of highway central separation band , but emphasizes that should be determined according to the function of central separation band This increases the design flexibility while also increasing the difficulty of width selection of central separation band. Through the analysis of relevant specifications, combined with relevant engineering practice, proposed the minimum width recommended value .Under the condition of meeting the basic function of the central separation belt.
