新型有轨电车交叉口一体化设计

Integrated Design of Intersection for New Trams

新型有轨电车系统多采用地面敷设,交叉口是设计的关键节点,需要各专业密切配合,进行一体化设计。以广州海珠新型有轨电车试验段为例,从工程设计、交通工程设计、交通秩序管理和安全设施等方面提出目前交叉口设计中应注意的相关问题。在工程设计方面,需考虑线路与道路、轨道等各专业的协调配合,实现工程的合理可行性;在交通工程设计方面,以尽量减少对既有交通的影响为原则,综合考虑路口渠化、交通控制、交通组织等方案,提高路口的通行能力;在路口交通秩序管理和安全设施方面,应重点考虑人行过街设施、设置相应的标志标线等,保证交通的有序及安全。只有通过上述3个方面的系统化设计,才能实现交叉路口功能最优化。

As new trams are mostly laid on the ground,the intersection is the key node in the design. The intersection design requires professional cooperation w ith each other in order to reach an integrated design. This paper takes the test section of the new trolley in Guangzhou as an example,and puts forw ard the relevant problems in the design of intersections from the aspects of engineering design,traffic engineering design,traffic order management and safety facilities. In the engineering design,it is important to consider the coordination among rails and roads,tracks and other professional systems to achieve the rational feasibility of the project; in terms of traffic engineering design,it is advised to minimize the impact on the existing traffic as a principle,and take into account the intersection of channelization,traffic control,traffic organization and other programs to improve the capacity of the junction; in the intersection of traffic order management and security,focus should be given to pedestrian crossing facilities,setting of traffic markings and signs,etc.,to ensure the orderly and safe transportation. The intersection function is expected to be optimized by w ay of systemic design in line w ith the improvement in the above-mentioned areas.
