德国现代有轨电车平交口信号优先

Elementary Discussion of Signal Control at Grade Intersection of Modern Tramcar in Germany

有轨电车交叉口信号优先既作为大力发展公共交通的举措之一,因此成为有轨电车交叉口信号控制中最热门的话题。各个拥有有轨电车的城市和相关设计单位研究机构都对其进行了各种探索。但是由于中国许多交叉口长期处于定时控制,因此对于灵活感应控制和有轨电车信号优先的技术还不是太成熟,并且对于其中一些细节和理念问题还存在理解上的误区。相比之下,德国自上世纪80年代以来就不断地探索有轨电车的交叉口信号优先,并随着智能交通系统的不断深化,在这方面的Know-how也日趋完善。

The tramcar signal priority at intersection is one of measures to greatly promote the public traffic.So it becomes the hottest topic in the signal control of tramcar at intersection. The cities operating tramcars,the relevant design offices and the research institutes have much explored on it. However, a large number of intersections in China are under the fixed time control. Therefore, the technology of flexible sensing control and tramcar signal priority is not too well known. Additionally, there is misunderstanding for some details and notions. In comparison, since the last century 80's, Germany has continuously researched the tramcar signal priority at intersection. And with the development of intelligent traffic systems, the Know-how in this field will be further improved.
