Abstract:
针对驾驶员在快速路下错出口匝道,未能第一时间到达理想的地面道路等情况,对城市快速路指路系统进行一系列的优化设计,最大限度地发挥指路系统的作用。同时,以宁波北外环快速路为例,将设计理念运用于实践。经过优化设计后的指路系统为车辆驾驶员提供全面准确的道路信息,引导车辆高效出行,进而有效缓解地面道路的交通压力。
According to the situation that drivers pick wrong off-ramps on the expressways and fail to reach the perfect ground roads in the first time, the paper takes a series of optimization on the guiding system of urban expressways in order to make it work at maximum limit. At the same time, illustrated by the example of Ningbo north external ring, this paper takes design concepts into practice. The optimized guiding system offers overall and accurate road information, guides vehicles to trip efficiently, and effectively mitigates traffic pressure of ground roads.

Open Journal of Transportation Technologies (OJTT) , 2015, DOI: 10.12677/OJTT.2015.41001
Abstract:
纯自行车流情况下非机动车道的通行能力计算公式,已经不能适用于混合非机动车流情况下的通行能力计算。本文根据现场调查和长期观察结果,得出宁波市区非机动车流中自行车和电动自行车的组成比例,并且通过实地调查、研究和数据计算处理得到混合非机动车流情况下非机动车道上的通行能力N值。
Non-motorized lane capacity calculation formula for pure bicycle flow cannot well apply to the case with mixed non-motorized vehicle flow. Based on field investigations and long-term observations, this paper studies the composition ratio of bicycles to electric bicycles for non-motorized traffic in the urban area of Ningbo. Through field surveys, research and data processing, the study obtain the possible capacity of non-motorized lane with mixed non-motorized vehicle flow.

Open Journal of Transportation Technologies (OJTT) , 2016, DOI: 10.12677/OJTT.2016.52006
Abstract:
针对单行交通在城市的运用存在盲目性和跟风性,本文从交通运行和交通影响这两个方面出发,在此基础上,按照“反映全面、相互独立、获取方便”的原则,得出单行片区交通运行状况的评价指标。通过层次分析法并结合宁波市的交通规划确定所选指标的具体权重,进而建立一个适合于宁波市使用的多指标综合评价模型。
Facing the problem of using one-way traffic in the city is blind and following suit, in this paper, the evaluation index is determined from two aspects of traffic operation and traffic impact and then the evaluation index of traffic operation status of one-way traffic area is obtained according to the principle of “reflecting the comprehensive, independent and convenient for each other”. Next, by means of analytic hierarchy process and combined with the traffic planning of Ningbo City, the specific weight of the selected index is determined finally to establish a multi index comprehensive evaluation model suitable for using in Ningbo City.
城市道路网络功能匹配度建模与实证分析
任刚,陆丽丽,许丽,水潮
中国公路学报 , 2012,
Abstract: ?为定量评价城市道路等级配置、功能定位和网络结构的合理性,借助功能匹配度(道路实际使用功能与规划设计功能的吻合程度)概念,从道路所承载交通的方式划分、距离分布及行车速度3类分流特征出发,利用层次分析法和模糊综合评判的数学方法,建立城市快速路、主干路、次干路、支路以及整个网络的功能匹配度分析模型。在大量实际城市交通调查数据的基础上,对模型参数进行了详细计算和标定。基于通用交通分析软件EMME/3的交通分配-路径分析功能,提取路段平均车速、分车型流量以及流量的起讫点信息等分流特征,进而获取模型所需的变量值。算例分析结果表明:该模型能够实现实际城市道路网络功能匹配度的定量计算,且具有实用性和可操作性。
