摘要
简述了交叉口改造的设计思路,包括路网改善、调整交叉口型式以及优化交通组织等。通过保定市中心区边缘六岔口改造方案研究,经多方案比选,近期采用交通管制,使绕行六岔口的部分车辆改道,交通量由5069pcu/h压缩到3668pcu/h;将六岔口改为十字交叉口,然后进行渠化,从而改善六岔口交通状况的方案。远期将采用分离式立交方案,彻底解决交叉口问题。
The design idea of the forks rebuilding has been presented in this p aper including road network improvement, adjusting fork types and optimizing traffic organization, etc. Through the rebuilding plan analysis of six forks in the edge of Baoding town and the selection of different plans, the immediate-term planning was to carry out traffic control to compress traffic capacity from 5 069 pcu/h to 3 668 pcu/h and change the six forks to crossroad, then, to make channelized engineering to improve the six forks traffic condition. In the future, a separation overpass plan would be adopted to resolve the intersection problem totally.
