小树从家去学校，再去集市。城市设计怎样改变每天花在路上的时间？Mia travels from home to school and then the market. How does city design change everyday travel time?
第 1 步：把活动聚在一起Step 1: Bring activities together
为什么许多人聚居一地？Why do many people live together?
城市集中居住、工作和公共服务。距离缩短可能方便交流。但人口集中也增加住房与设施需求。城市不是只有高楼。Cities concentrate homes, work, and public services. Proximity can make exchange easier. Concentration also increases demand for housing and infrastructure. A city is more than tall buildings.
第 2 步：连接方式影响可达性Step 2: Connections affect access
近在地图上，就一定到得了吗？Does closeness on a map guarantee access?
河流、道路和台阶可能成为障碍。公共交通与步行网络连接目的地。可达性要看时间、费用和身体条件。直线距离只是其中一项。A river, road, or steps can be a barrier. Transit and walking networks connect destinations. Access depends on time, cost, and physical ability. Straight-line distance is only one factor.
怎样让更多人生活方便？How can convenience extend to more people?
规划要兼顾住房、交通与绿地。密度高低都不能单独判断好坏。居民参与帮助识别遗漏需求。方案要用实际使用结果检验。Planning balances housing, transport, and green space. Density alone does not determine quality. Participation helps reveal overlooked needs. Plans should be tested against how people actually use them.

家位于二，河在五。学校在河对岸且桥关闭时，绕行增加四单位。桥开放后走直接街道。简化示意。Home is at 2; the river is at 5. A school across the river adds a 4-unit detour when the bridge is closed. An open bridge permits the direct street. Schematic only.
一句话记住它：Remember it:城市设计组织距离与连接，目标是让生活服务更可达。City design organizes distances and connections so everyday services become accessible.
城市集中居住、工作和公共服务。Cities concentrate homes, work, and public services.河流、道路和台阶可能成为障碍。A river, road, or steps can be a barrier.规划要兼顾住房、交通与绿地。Planning balances housing, transport, and green space.
城市系统框架：较高把握。简化地图不代表具体城市的交通预测。High confidence in the systems framework. The simplified map does not forecast traffic in a particular city.
