现代有轨电车与市政道路协调问题探讨

现代有轨电车作为低碳环保、安全可靠、美观舒适的绿色交通方式,兼有地铁、公交的诸多优点。现代有轨电车一般敷设在市政道路路中或路侧,由此会带来交通组织与信号控制、横断面布设、平面线形协调、纵断面标高协调、路基路面过渡等诸多问题。基于此,以现代有轨电车敷设在沥青路面道路中央为例,对二者交通组织、平纵横协调、路基路面衔接过渡等技术问题进行分析,并提出协调措施:通过对区域路网、路段及交叉口、沿线单位出入口、行人过街交通组织的优化,确保行车安全;在市政道路靠近有轨电车一侧设置30 cm宽平石,并预留0.5 m路缘带,有轨电车适当预留限界外空间,以确保二者限界不重叠;通过设置立缘石和平石,协调有轨电车专有路权段的超高和工后沉降差异问题;交叉口混行路段,通过轨道左线和右线与剩余部分交叉口分别形成路口进行竖向设计,以实现高程协调;同时设置过渡段,协调有轨电车与市政道路混行段路基的差异沉降。

Several Issues Discussion of Modern tram and municipal road Coordination transition

The modern trams have many advantages of the subway and bus as low carbon environmental protection, safe and reliable, comfortable and beautiful green traffic ways. The modern trams are generally laid in the path of municipal roads or road side. The resulting brings traffic organization and signal control, cross section layout, coordination of horizontal and vertical alignment, subgrade and pavement transition and so on. Based on this, take the modern tram laying middle of the asphalt pavement for example, the tram and municipal road traffic organization, coordination of horizontal and vertical alignment, subgrade and pavement cohesion transition and other technical issues are discussed and analyzed. It puts forward a series of coordination measures. The main conclusions are as follows: through the regional road network, roads and intersections, entrances and exits along the unit, pedestrian crossing traffic organization and optimization to ensure road safety. Set 30cm wide flat stone in the municipal road near the tram, and set aside 0.5m with curbs, the tram right reserved clearance space to ensure that the two do not overlap. Ultrahigh and engineering settlement difference problems of tram exclusive right of way section are co-ordinated by setting the vertical curb stone peace. In the mixed road intersections, junction vertical design was formed by rail line and the right line and left the remainder of the intersection, in order to achieve the elevation coordinate. While setting transition section, coordinating subgrade settlement difference between trams and municipal roads mixed section.
