摘　　要：历史城区内有丰富的支路和街巷,运用支路和街巷进行交通微循环组织是交通改善的重要途径。首先分析历史城区微循环路网的作用及建设管理现状。分"分流导向、服务短距离出行"的城区级微循环、"集散导向、服务地块可达"的街区级微循环两个层级,介绍微循环路网的分层规划方法和交通工程设计及管理要点。在此基础上。Historic areas are usually characterized by abundant alleys and streets. Using these alleys and streets for micro-circulation is an important means to improve overall traffic conditions. This paper analyzes the functions and existing con- ditions of micro-circulation. The road network for micro-circulation is divided into two levels. The first level is the city-level network, which airms to service short distance travel. The second level is the neighborhood-level network, which airms to service the accessibility of neighborhoods. Based on such functional division, a double-layered planning method and corresponding traffic engineering solutions are proposed. In a addition, a case study of the old city of Nanjing is used to il- lustrate the prposed methodology.
