分析目前城市桥梁交通安全存在的问题，针对重庆东水门长江大桥、千厮门嘉陵江大桥（简称两江大桥）项目，从标志布设、标线布设、突起路标、轮廓标、防撞桶及TPU柱和特殊段落的安全保障措施等方面阐述两江大桥交通安全设施设计，并对标志版面、普通热熔型标线及双组份标线分别进行结构验算和比较分析，提出两江大桥交通安全设施优化设计方案，以满足桥梁安全运营的需要。

Optimal Design of Traffic Safety Facilities on Chongqing Two-river Bridges

This paper analyzes the problems in traffic safety of urban bridges at present, expatiates design of traffic safety facilities of Two-river Bridges from the aspects of layout of marks, layout of marked lines, protruding signs, delineators, anti-collision drums and TPU columns as well as safety guarantee measures for special sections, etc. in allusion for Chongqing Dongshuimen Yangtze River Bridge and Qiansimen Jialing River Bridge （ Two-river Bridges for short） project, and performs structural check computation and comparative analysis for mark layout, common hot melt marked lines and double-component marked lines, respectively so as to propose an optimal design scheme for traffic safety facilities of Two-river Bridges to satisfy the need of safe operation of bridges.
