【摘要】：京津冀一体化战略中的核心战略是疏解北京市的非首都功能。在这样的背景下,本文着重研究了实际交通状况下北京市物流中心外迁的问题,分析物流中心外迁前后配送车辆对北京市交通的影响变化,以及不同交通状况对外迁后物流中心配送活动的影响。为此,本文在分析北京市现有物流中心布局的基础上,提出了京津冀一体化下,物流中心外迁后的新的物流布局假设,即武清、涿州、固安、香河、三河、顺义天竺六个物流中心。为了能对比分析,本文进一步选取了京卫利达、华润京龙、亦庄、马驹桥、天竺五个物流中心代表现有物流中心布局。在物流中心分布的基础上,本文分析了北京市物流需求分布及实际交通状况,建立了北京市城市配送仿真模型。在物流中心外迁前后对比分析的问题上,物流中心外迁后,北京市城市配送的单次平均配送时间和单次平均配送距离都发生了显著升高,这和物流中心外迁后物流中心距北京市区的距离增加直接相关。通过细分平均单次配送时间和距离在不同类型道路上的分布,发现配送时间和距离的前后差异主要表现在高速路、五环和六环道路上。另外,仿真结果还表明,外迁后,配送车辆在整个北京市路网产生的交通负荷没有表现出显著性差异,但对于四环道路而言,配送车辆产生的交通负荷量明显降低。在交通状况变化对新物流中心布局配送活动特点分析上,本文把北京市的交通状况划分为畅通、基本畅通和拥堵二种模式,并从配送距离、配送时间和交通负荷量及分布三方面分析配送特点。平均单次配送距离基本不受交通模式的影响,但距离在不同换线道路上的分布却受到较大的影响;配送时间随交通拥堵状况的加剧呈递增趋势,其中香河和三个两个地方收交通影响最大;除了三河和香河,交通负荷量和交通负荷分布基本不受交通状况的影响。综上所述,在物流中心外迁问题上,物流中心外迁后,配送车辆在北京市四环道路上产生的负荷显著降低,但整个配送时间却显著增加;在交通状况对配送活动影响方面,交通状况的变化对配送时间具有显著的影响,对三河和香河两个物流中心,交通状况的变化对配送车辆的路径选择有显著影响。
[Abstract]:The core strategy of the strategy of integration of Beijing, Tianjin and Hebei is to uncover the non capital functions of Beijing. Under such a background, this paper focuses on the relocation of logistics centers in Beijing under actual traffic conditions, analyzes the impact of distribution vehicles on Beijing's transportation before and after the relocation of logistics centers, and the influence of different traffic conditions on the distribution activities of logistics centers after relocation. Therefore, based on the analysis of the layout of the existing logistics centers in Beijing, this paper puts forward the new logistics layout assumption after the relocation of the logistics center, namely Wuqing, Zhuozhou, Guan, Xianghe, Sanhe and Shunyi Tianzhu six logistics centers. In order to compare and analyze, this paper further selected JINGLIDA, Huarun Jinglong, Yizhuang, Majuqiao and Tianzhu five logistics centers to represent the layout of existing logistics centers. On the basis of the distribution of the logistics center, this paper analyzes the distribution of logistics demand and the actual traffic situation in Beijing, and establishes the simulation model of Beijing city distribution. In the comparative analysis before and after the relocation of the logistics center logistics center on the issue, after the relocation, the average of single delivery time Beijing city distribution and single average distribution distance was significantly increased, and the logistics center logistics center relocated from Beijing city to increase the distance is directly related to. By subdividing the distribution of average single delivery time and distance on different types of roads, it is found that the difference between distribution time and distance is mainly manifested in highways, rings and six ring roads. In addition, the simulation results also show that after the relocation, the traffic load produced by the distribution vehicle in the whole Beijing road network has not shown significant difference, but for the four ring road, the traffic load generated by the distribution vehicle is significantly reduced. Based on the analysis of the traffic situation and the layout and distribution activities of the new logistics center, the paper divides the traffic status of Beijing into two modes: smooth, basically smooth and congested, and analyzes the distribution characteristics from three aspects, such as delivery distance, delivery time, traffic load and distribution. The average single delivery distance is basically not affected by traffic patterns, but the distribution in different distance change line on the road is affected; presenting the delivery time with traffic congestion intensifies increasing trend, including Xianghe and three two places receiving maximum traffic impact; in addition to the three river and Xianghe, the influence of traffic load and the traffic load distribution is not affected by traffic conditions. In summary, the relocation of the logistics center, logistics center relocation, delivery vehicles produced in Beijing city of Victoria Road load decreased significantly, but the delivery time was significantly increased; in the traffic impact on the distribution activities, the changes of traffic condition has significant influence on the distribution of time, Sanhe and Xianghe two logistics center, the change of the traffic status of the vehicle path have significant impact.
