Use: residential with limited neighborhood services
Character: low-rise residential, townhouses, row houses, small apartment buildings
Ground floor: residential with front gardens or courtyards
Parking: maximum 1.0 space/unit, on-street + private garages
Public realm: residential streets with traffic calming, green corridors connecting to station
Worked Example: Metro Station TOD Program Calculation
Assumptions: Metro station, urban context, 800m catchment, circular area
Total catchment area = pi x 800^2 = 2,010,619 m2 = 201 ha
Less roads and infrastructure (25%): 201 x 0.75 = 151 ha net developable
Less parks and open space (15%): 151 x 0.85 = 128 ha net buildable
Zone A (0-200m): pi x 200^2 = 12.6 ha gross -> 8.0 ha net -> FAR 6.0 -> 480,000 m2 GFA
Zone B (200-400m): pi x (400^2 - 200^2) = 37.7 ha gross -> 24.0 ha net -> FAR 3.5 -> 840,000 m2 GFA
Zone C (400-600m): pi x (600^2 - 400^2) = 62.8 ha gross -> 40.0 ha net -> FAR 2.0 -> 800,000 m2 GFA
Zone D (600-800m): pi x (800^2 - 600^2) = 87.9 ha gross -> 56.0 ha net -> FAR 1.0 -> 560,000 m2 GFA
TOTAL GFA: 2,680,000 m2
Program split (typical metro TOD):
Residential (55%): 1,474,000 m2 -> at 80 m2/unit = 18,425 units -> at 2.5 persons/unit = 46,000 people
Office (20%): 536,000 m2 -> at 15 m2/employee = 35,700 jobs
Retail (10%): 268,000 m2
Civic/Institutional (10%): 268,000 m2
Hotel (5%): 134,000 m2 -> at 35 m2/key = 3,800 keys
Residential density: 46,000 people / 201 ha = 22,900 people/km2 (exceeds ITDP 15,000 threshold)
Combined density: 46,000 residents + 35,700 workers = 81,700 / 201 ha = 40,600 people/km2
4. First-Last Mile Design
The quality of first-last mile connections determines whether people actually
walk or cycle to the station. A station with poor last-mile connectivity will
underperform its ridership potential by 30-50%.
Pedestrian Network Quality
Continuous sidewalks: both sides of every street within the catchment, minimum 2.0m clear
Direct routes: pedestrian desire lines should be honored with direct paths to station; route directness ratio less than 1.3
Level of service: smooth, even surfaces; ADA-compliant curb ramps at every crossing; tactile paving at crossings and platform edges
Shade and weather protection: continuous shade canopy (trees or structures) along primary pedestrian routes to station; covered walkways within 200m of station entrance in hot or wet climates
Lighting: minimum 10 lux along pedestrian routes, 30 lux at crossings and station approaches, CPTED (Crime Prevention Through Environmental Design) principles
Active frontages: ground-floor retail and services along main walking routes to create safe, interesting, surveilled streets
Cycling Connections
Protected bike lanes: physically separated cycle tracks on all routes leading to station from catchment edge
Wayfinding: cycling wayfinding signage from 1 km out, with distance and time-to-station information
Intersection treatment: protected intersections or bike signals at all crossings with arterial roads
Gradient management: maximum 5% gradient on cycling routes; provide alternative routes around steep hills
Winter maintenance: snow clearing on cycling routes within 4 hours of snowfall (cold climates)
Bicycle Parking at Station
Quantity: minimum 50 spaces for metro, 30 for LRT, 20 for BRT; scale upward based on ridership
Types: mix of short-term (inverted-U racks, 2-hour) and long-term (secure, covered, card-access, 24-hour)
Location: visible from station entrance, within 30m of entrance, well-lit (50 lux minimum)
Design: covered to protect from rain, spaced at 0.75m intervals, accommodate cargo bikes and e-bikes
Charging: e-bike charging at 10% of spaces, standard power outlets
Feeder Transit
Bus routes: local bus routes should terminate at or pass through the station, with stops within 100m of main entrance
Transfer design: weather-protected transfer areas, coordinated schedules, real-time information displays
Frequency: feeder buses every 10-15 minutes during peak, 20-30 minutes off-peak
Route design: feeder routes should cover the catchment area beyond comfortable walking distance (800m+)
Kiss-and-Ride and Rideshare
Location: short-term drop-off/pick-up zone within 100m of station entrance, separated from bus and pedestrian areas
Capacity: 5-10 spaces for kiss-and-ride, 3-5 spaces for taxi/rideshare
Design: 60-second maximum dwell time, no waiting/parking allowed, ANPR enforcement
Rideshare integration: designated pick-up zone with shelter, real-time app coordination, clear signage
Wayfinding System
Hierarchy: regional wayfinding (from 2 km: highway signs), district wayfinding (from 500m: totem signs), local wayfinding (within 200m: finger posts and ground markings)
Information: walking time to station, cycling time, next departure time, accessible routes
Consistency: unified design language, multilingual where appropriate, tactile and audible elements for universal access
Digital integration: QR codes linking to real-time transit information, augmented reality wayfinding in station areas
5. Station Area Design
The station itself is the heart of the TOD. Its design determines how
effectively the surrounding development connects to transit and how the
public realm functions as a civic space.
Station Plaza Design
Minimum size: 0.25 ha (2,500 m2) for metro station, 0.10 ha for LRT/BRT
Location: directly at the primary station entrance, visible from main approach streets
Proportions: width at least 1.5x the height of surrounding buildings for solar access and spatial comfort
Level change: minimize level changes between plaza and station entrance; maximum one step or ramp
Programming: flexible space for daily use (seating, planting, retail kiosks) and events (markets, performances, gatherings)
Seating: minimum 1 seat per 30 m2 of plaza area, mix of primary (benches with backs) and secondary (walls, steps, ledges)
Weather protection: covered areas at minimum 20% of plaza; canopy, arcade, or building overhang
Retail kiosks: 2-5 kiosks or pop-up retail structures to activate the plaza and provide convenience services (coffee, news, flowers, bike repair)
Materials: high-quality, durable paving (natural stone, high-grade concrete); distinct from surrounding sidewalks to signal civic importance
Water management: permeable paving or integrated drainage; consider water feature (fountain, stream) for microclimate and placemaking
Interchange Design (Multi-Modal Stations)
Bus-rail integration: bus stops within 100m of rail platform, preferably same level or one level change with escalators/elevators
Cross-platform transfer: where two rail lines intersect, same-platform transfer is ideal (arriving passengers step across platform to connecting train)
Walking distances: maximum 300m between any two modes at an interchange; target under 200m
Wayfinding: real-time information for all modes at every decision point; overhead signage visible from 30m
Capacity: size interchange facilities for 150% of projected peak demand to handle surges and events
Retail integration: convenience retail in transfer corridors (not obstructing flow) to enhance the transfer experience
Air Rights and Real Estate Integration
Building over stations: develop air rights above station structures for maximum land value capture
Structural coordination: design station structure from inception to support future air-rights development (column grid aligned with building module, structural capacity for 20+ stories)
Entrance integration: building lobbies and retail concourses should merge seamlessly with station entrances
Revenue model: ground lease or air-rights sale to fund station construction and ongoing maintenance
Precedents: Hong Kong MTR model (rail + property development funds 40% of operating costs), Tokyo station area developments, Hudson Yards NYC
Underground Connections
Climate justification: in cities with extreme heat, cold, or rain, underground pedestrian networks extending 200-400m from station
Commercial activation: underground passages lined with retail to maintain activity and safety
Daylight: skylight wells or light scoops to bring natural light into underground passages every 50-80m
Accessibility: elevators and escalators at every level change; tactile wayfinding throughout
Ventilation: mechanical ventilation to maintain comfortable temperature and air quality; target 25-27C in tropical climates, 18-22C in temperate
6. Parking Management
Parking policy is the single most powerful lever for making TOD work. Excessive
parking undermines transit ridership, wastes land, increases costs, and
generates traffic. The following parking management framework is calibrated for
TOD contexts.
Maximum Parking Ratios by Zone
| Use | Zone A (0-200m) | Zone B (200-400m) | Zone C (400-600m) | Zone D (600-800m) |
These are maximums, not minimums. Zero parking minimums should be the
baseline policy within the entire TOD catchment.
Parking Design Requirements
No surface parking within 400m of station (Zone A and B)
Structured parking must be wrapped with active uses on all street-facing facades
Underground parking preferred in Zone A; structured in Zone B
Maximum parking structure frontage: 15m of blank facade (service entrance only); remainder must be active use
Parking access: from secondary streets or alleys, never from the primary pedestrian street
EV charging: minimum 20% of spaces with Level 2 charging, conduit to 100% of spaces
Parking Pricing and Management
Unbundling: residential parking sold or rented separately from housing units (typical cost: $30,000-$60,000 per structured space to build)
Pricing: market-rate pricing for all parking; never provide free parking in a TOD
Shared parking: office and residential parking shared where peak demands are complementary (office peaks weekdays 9-17, residential peaks evenings and weekends)
Shared parking reduction: typically 20-30% fewer total spaces needed versus single-use parking
Car-share: dedicated car-share spaces at 1 per 20 residential units; each car-share vehicle replaces 8-13 private vehicles
Dynamic pricing: implement demand-responsive pricing for on-street parking (target 85% occupancy, per Donald Shoup methodology)
Park-and-Ride
Terminus stations only: park-and-ride is appropriate only at end-of-line or suburban stations where feeder transit is insufficient
Never within the walkable core: park-and-ride should be at the periphery of the catchment (600-800m from station) or outside it entirely
Structured, not surface: surface park-and-ride lots are land-use failures; structure parking and develop adjacent parcels
Phase out over time: as surrounding development densifies and feeder transit improves, convert park-and-ride to development
