跨座式单轨交通的认识误区分析及发展展望

跨座式单轨是一种优良的中运量轨道交通系统制式,具有环保性能好、景观效果好、地形适应能力强、投资低、建设周期短、占地少等优点,也存在冰雪天气适应能力差、牵引能耗高的缺点,部分人士对跨座式单轨在橡胶粉尘、疏散救援、运营安全、运营成本、适应范围、景观影响和土地开发等方面存在认识误区。对上述缺点及认识误区一一进行释疑,并分析跨座式单轨未获广泛推广的原因,进一步针对我国城市轨道交通发展现状、存在问题、国家政策导向进行分析,提出随着城市轨道交通发展阶段的转变,应消除对跨座式单轨的认识误区,在其适应范围内大力推广,促进我国城市轨道交通的可持续发展。

Eliminate Misunderstanding and Promote Development of Straddle Monorail

Straddle monorail is a good means of urban rail transit of medium capacity. It has the advantages of environmental protection,good landscape effect,strong topography adaptability,low cost,short construction time,small coverage area,and but it also has the disadvantages of poor adaptability to ice and snow,high traction energy consumption. There remain some misunderstanding on rubber dust,evacuation and rescue,operation safety,operation cost,adaptive scope,landscape effect and real estate.This paper addresses the disadvantages and misunderstanding,analyzes the causes for low application.Furthermore,it analyzes the current status and problems involved in urban rail transit development and the national guiding policy. Finally,with the stage transformation of urban rail transit development,the misunderstanding should be eliminated and sustainable development of urban rail transit promoted.
