通信工程文献翻译——微循环运输理念是为了通过分支道路在主干道上分流重型交通工具而提出的。开发设计微循环交通网络的优化模型是为了选择分支路作为分支渠道，并确定其所需能力，尽量减少总体重建费用和占地面积饱和度和重建空间约束，同时考虑到网络用户路由的选择行为。由于微循环运输网络设计包括离散和连续另个变量问题，因此开发了一组离散变量和连续变量变换成一组新的离散变量的离散化方法，将混合网络设计问题转化为新的离散网络设计问题具有多重价值。遗传算法的提出是用来解决新的离散网络设计问题。最后一个数字示例演示了模型和算法的有效性。

1.绪论

城市微循环运输是人类血液循环系统中借用的拟人[1]。 在血液微循环系统中，血液从小动脉流向微循环血管，然后从微循环血管流回小静脉。类似于血液微循环，微循环可以定义为从动脉道路到分支道路微循环道路的流动，然后从分支道路流回到动脉道路。一般来说，大多数车辆在主干道上行驶，所以主干路通常在高峰时段非常拥挤。如果微循环运输网络围绕动脉道路的“堵塞点”进行设计，则既可以使车辆在主干道上行走，并将部分车辆通过微循环路支路进行分流。

实际上，由于道路路面狭窄，功能复杂，一些分公路主要用于区域内交通工具使用（如行人、自行车、少数车辆[2,3]），并且不具

备分流动脉的能力。微循环道路系统是为了实现分流而设计的，这就需要挑选一些条件好的分支道路进行重建。因此，需要解决两个问题：一是确定哪些分公路应当被挑选为交通通道；另一个是确定重建后这些选定道路所应当的能力。微循环运输为减少交通拥堵提供了有效和经济的方式，因为它不需要增加新的道路，而是利用现有的分支道路来实现分流。最近在中国，像北京、昆明这样的一些大城市，在一些拥挤的地区就已将建立了微循环交通......

The idea of microcirculation transportation was proposed to shunt heavy traffic on arterial roads through branch roads. The optimization model for designing micro-circulation transportation

network was developed to pick out branch roads as traffic-shunting channels and determine their required capacity, trying to minimize the total reconstruction expense and land occupancy subject

to saturation and reconstruction space constraints, while accounting for the route choice behaviour of network users. Since micro-circulation transportation network design problem includes both

discrete and continuous variables, a discretization method was developed to convert two groups of variables  discrete variables and continuous variables into one group of new discrete variables,

transforming the mixed network design problem into a new kind of discrete network design problem with multiple values. The genetic algorithm was proposed to solve the new discrete network design problem. Finally a numerical example demonstrated the efficiency of the model and algorithm.

1. Introduction

Urban microcirculation transportation is an impersonate noun borrowed from human blood circulation system  1 . In the blood microcirculation system, blood flows from arterioles to microcirculation vessels and then flows from the microcirculation vessels back to venules.

Similar to the blood microcirculation, traffic microcirculation can be defined as traffic flows from arterial roads to branch roads microcirculation roads and then flows from branch roads back to arterial roads. In general, most of vehicles run on the arterial roads, so arterial roads usually become very congested at peak hours. If microcirculation transportation network is designed around “jam points” of arterial roads, traffic on arterial roads can be......
