新型轨道交通信号系统展望

Prospect of New Rail Transit Signal Systems

国内除钢轮钢轨轨道交通外,并存有跨座式单轨轨道交通及有轨电车轨道交通,跨座式单轨和有轨电车从投资角度来讲优势更明显于轮轨;对于单轨系统噪声明显小于轮轨,适合地面段建设,还具备更强的爬坡能力和小曲线半径适应能力。而有轨电车信号系统在造价上更具有优势,同时具备系统组成简单,施工工期短的优点。作为突破钢轮钢轨的传统的新型轨道交通形式,主要针对跨座式单轨和有轨电车系统进行分析。

As to domestic metro lines, besides the steel wheel rail, there are the straddle monorail and railroad car lines. From an investment perspective, the advantage of the later is more apparent. Of which the monorail system has lower noise than the wheel-rail, suitable for the construction on the ground, and it also has more climbing ability and small curve radius adaptability. The signal system of the railroad car line has more advantages in the cost aspect, and is featured with the simple system structure and short construction period. The paper mainly analyzes the monorail and railroad car systems as a breakthrough in the traditional model of the metro lines.
