Abstract:Tram has the advantages of safety, high speed and low cost, but it will occupy certain road resources and bring certain influence on the current road cross-sectional layout and traffic organization at intersections. Combined with the Yizhuang New Town Modern Tram T1 Ling Project, the reasonable distribution mode of the right of way between tram and urban road system is analyzed. The traffic demand of road is determined through traffic volume prediction. And combined with the influence of tram after placed on the current roads, the reasonable adjustment mode of road cross-section is determined on the premise of satisfying the road traffic demand, reducing the engineering quantities and reducing the current tree cutting and removal. According to the intersected road grade and different traffic flows, the traffic organization of urban road traffic system at intersection after the tram is placed is analyzed. The reasonable and efficient intersection traffic organization form among the tram system, motor vehicle system and slow traffic system is explored. According to the different situations, the strategies of shared phase, absolute priority control or relative priority control are adopted. In combination with island type and side type stations, the different facilities for pedestrians to cross a street for the second time are set up, and the right of way of non-motorized lane is clarified through the traffic markings so as to ensure the safety and order of slow traffic system. Finally, the design experience of the Yizhuang New Town Modern Tram T1 Ling Project is summarized from the aspects of its cross-sectional arrangement, intersection traffic organization and slow traffic system.
