Ideas for shortcut modelling

- [ ] Each shortcut has a detour ratio indicating likeliness. When we count shortcuts per road, we could try weighting by this.
- [ ] If we have good OD data for the predict-impact mode and have a sense of study area-wide traffic patterns, we could see what shortcuts currently occur in practice, and maybe weight the (entry, exit) pairs somehow?
- [ ] As you place filters, shortcut coloring constantly re-scales to show the worst problem. Optionally remember the original max_shortcuts before edits, and show relative to that?

该 issue 描述了在低流量街区设计工具中对捷径进行建模的想法。它提到了绕行比、OD 数据和捷径着色。首先，查找现有的捷径建模代码，可能位于前端可视化或模拟逻辑中。确定当前如何定义、计数和显示捷径。这项工作涉及设计决策和新指标的集成，因此必须了解当前的架构和数据流。
