The operational state of the stream at the conflict points in non-signal intersection of forest roads is studied and a viewpoint that the conflicting streams take up the resource of the conflict points in turn is advanced.
研究了林区道路无控交叉口冲突点处的交通运行状况,提出了无控交叉口相冲突车辆车流轮流占用冲突点资源的观点;从理论分析的角度提出了无控交叉口冲突点延误的计算模型。
Authors proposed a road alignment optimization method based on genetic algorithm.
提出一个基于遗传算法的道路选线优化模型,该模型首先随机生成新建道路空间位置的候选方案集,并依据GIS平台自动设计新建道路的平竖曲线,并计算其各项工程费用;接下来,分析变化了的路网的拓扑结构,并在新路网中分配OD交通量,获得OD交通在新路网上的交通流特征,进而计算OD交通量的走行时间和在路网上的环境负荷;然后,利用工程费用、OD交通走行时间费用和环境负荷当量费用构造适应度函数,以判断各候选方案的优劣,同时实施选择、交叉、变异操作以获得更多的候选方案,直至得到一个最佳的新建道路方案为止。
The application of the digital photographic survey to the path route selection is indroduced.
计算机技术的飞速发展,给道路设计带来了极大的方便,数字摄影测量在道路选线中的应用,其过程主要是利用全数字摄影测量系统(VirtuoZo)生成DEM(数字高程模型),由建立的带状DEM内插出带状横断面,自动绘制公路路线平面地形图;再根据平面曲线各个测点的平面坐标和带状DEM内插线状纵断面,最后将线状纵断面进行平滑处理。
