Summary

Design transit-oriented developments using ITDP TOD Standard, global best practices, and density-distance gradient principles. Use when the user asks to design around a transit station, create a TOD plan, optimize development near transit, plan a transit district, design a statio

1	# Transit-Oriented Development (TOD) Design Skill
2
3	This skill provides a complete framework for designing transit-oriented
4	developments based on the ITDP TOD Standard v3.0, global best practices from
5	cities like Tokyo, Hong Kong, Copenhagen, Curitiba, and Singapore, and
6	density-distance gradient principles derived from decades of empirical research.
7	It covers the full workflow from transit mode classification through station area
8	planning, density calibration, use mix programming, parking management, and
9	first-last mile connectivity design.

12
13	## 1. TOD Typology Selector
14
15	Use the following matrix to determine the baseline design parameters for any
16	TOD project. Start by identifying the transit mode, then adjust using the
17	context modifiers below the table.
18
19	### Primary Classification by Transit Mode
20
21	\| Transit Mode \| Walk Catchment \| Min Density \| Typical FAR \| Height Range \| Character \|
22	\|---\|---\|---\|---\|---\|---\|
23	\| Metro / Heavy Rail \| 800m \| 100 DU/ha \| 3.0 - 10.0 \| 6 - 40+ stories \| Urban center, regional destination, highest intensity mixed-use \|
24	\| Light Rail / Tram \| 600m \| 60 DU/ha \| 2.0 - 5.0 \| 4 - 12 stories \| Urban neighborhood, linear corridor with medium-intensity nodes \|
25	\| BRT (Bus Rapid Transit) \| 500m \| 50 DU/ha \| 1.5 - 4.0 \| 3 - 8 stories \| Boulevard district, corridor-based development \|
26	\| Bus (frequent, <10 min headway) \| 400m \| 30 DU/ha \| 1.0 - 2.5 \| 2 - 5 stories \| Neighborhood center, incremental densification \|
27	\| Commuter Rail \| 800m \| 40 DU/ha \| 1.5 - 4.0 \| 3 - 8 stories \| Town center, park-and-ride transition to walkable core \|
28	\| Ferry Terminal \| 400m \| 50 DU/ha \| 2.0 - 5.0 \| 3 - 8 stories \| Waterfront district, tourism + residential + commercial \|
29
30	### Context Modifiers
31
32	Apply these after selecting the primary transit mode to fine-tune parameters:
33
34	\| Context \| Density Modifier \| FAR Modifier \| Notes \|
35	\|---\|---\|---\|---\|
36	\| CBD / Central City \| +50% \| +2.0 to +5.0 \| Highest intensity justified by regional accessibility \|
37	\| Interchange Station (2+ lines) \| +30% \| +1.5 to +3.0 \| Multi-modal hub attracts higher ridership and demand \|
38	\| Terminus / End-of-Line \| -20% \| -0.5 to -1.0 \| Lower accessibility; park-and-ride may be appropriate \|
39	\| Suburban / Greenfield \| -30% \| -0.5 to -1.5 \| Lower existing demand; phase density over time \|
40	\| Historic / Heritage Area \| -20% \| -1.0 to -2.0 \| Height and massing constraints; character preservation \|
41	\| University / Hospital Anchor \| +20% \| +0.5 to +1.5 \| Institutional trip generators increase demand \|
42	\| Waterfront / Park Edge \| No change \| No change \| Adjust massing for view corridors and public access \|
43
44	### Walk Catchment Adjustments
45
46	The standard walk catchments above assume flat terrain and a connected street
47	grid. Adjust as follows:
48
49	- Hilly terrain (>5% average slope): reduce catchment by 20%
50	- Poor street connectivity (cul-de-sac pattern): reduce catchment by 25%
51	- Barriers (highway, river without crossing, rail line): truncate catchment at barrier
52	- Excellent pedestrian environment (wide sidewalks, shade, weather protection): increase catchment by 15%
53	- Covered or air-conditioned connections (Hong Kong, Singapore model): increase catchment by 25%
54
55	---
56
57	## 2. ITDP TOD Standard -- 8 Principles
58
59	The Institute for Transportation and Development Policy (ITDP) TOD Standard
60	v3.0 provides an internationally recognized framework for evaluating and
61	designing transit-oriented developments. The standard scores developments on
62	a 0-100 scale across 8 principles. Use these principles as both a design
63	checklist and a scoring rubric.
64
65	### Scoring Thresholds
66
67	\| Award Level \| Minimum Score \| Interpretation \|
68	\|---\|---\|---\|
69	\| Gold TOD Standard \| 85 or above \| World-class TOD; exemplary in all dimensions \|
70	\| Silver TOD Standard \| 70 - 84 \| High-quality TOD; strong performance with minor gaps \|
71	\| Bronze TOD Standard \| 55 - 69 \| Good TOD; meets core criteria but has improvement areas \|
72	\| Below Bronze \| Below 55 \| Does not qualify as TOD; significant redesign needed \|
73
74	### Principle 1: WALK (0-15 points)
75
76	Goal: Create a safe, complete, and comfortable pedestrian environment that
77	makes walking the most attractive mode for short trips.
78
79	Scoring Criteria:
80	- Pedestrian network is complete with no gaps or dead ends (0-3 pts)
81	- Block perimeters are less than 250m for at least 90% of blocks (0-3 pts)
82	- Pedestrian crossings are safe, frequent, and accessibl
