摘要:

城市道路网络中,各等级道路之间衔接的合理与否直接关系到相关道路乃至整个道路网络期望功能的实现.本文以不同等级道路功能分析为基础,提出城市综合交通规划的道路网规划,以交通功能为主要目标的城市道路网络系统专项规划,以服务功能为主要目标的道路网络衔接规划的总体思路.结合以概率统计为基础的蒙特卡罗算法,分别计算交通功能和服务功能的系统可靠度,以作为不同阶段道路网络衔接的主要评价指标,并探讨道路网络衔接中的越级交叉问题.最后以郑州市某区域道路网络为例,验证了本文方法的可行性与适用性.

关键词: 城市交通, 道路功能, 道路衔接, 系统可靠度

Abstract:

Whether the junction between different grades of roads is reasonable is directly related to the realization of the desired function of the road network. Based on the functional analysis, this paper puts forward the evaluation method of road network junction planning. At the stage of urban integrated transportation planning, the main goal is to provide the traffic function; while for the stage of urban road network special planning, it is to guarantee the service function. Using Monte Carlo simulation method, the system reliability of traffic function and service function are calculated, which are considered as the main evaluation indexes of road network junction schemes. The leapfrog cross-cutting problem is also discussed. Finally, a regional road network of Zhengzhou city is taken as an example for application, to testify the feasibility and rationality of the proposed method.

Key words: urban traffic, road function, road junction, system reliability
