Design complete streets with proper cross-sections, lane allocation, pedestrian and cycling infrastructure, intersection design, and streetscape elements using NACTO and global standards. Use when the user asks to design a street, create a cross-section, determine road width, design an intersection, plan a bike lane, design a sidewalk, create a boulevard, design a shared street, plan traffic calming, or specify streetscape elements. Also use for street hierarchy classification, right-of-way allocation, or any question about street dimensions and standards.
Street Design Skill
This skill provides comprehensive street design guidance based on NACTO Urban Street Design Guide, Global Designing Cities Initiative (GDCI), AASHTO Green Book, and international best practices. It covers the full workflow from street hierarchy classification through cross-section dimensioning, intersection design, streetscape specification, and traffic calming.
Street Hierarchy Classification
Use the following decision tree to classify any street. Start with the Average Daily Traffic (ADT) count, then apply contextual modifiers.
Primary Classification by ADT and Function
Arterial (>15,000 ADT)
Right-of-Way (ROW): 30-40m
Lanes: 2-3 per direction (3.0-3.3m each)
Design speed: 40-50 km/h (urban), 50-60 km/h (suburban)
Transit: dedicated bus/BRT lanes strongly recommended
Cycling: protected bike lanes required (physically separated)
Pedestrian: wide sidewalks 3.6-6.0m, pedestrian refuge islands at crossings
Median: 3.0-6.0m landscaped or transit median
Signal spacing: 200-400m typical
Role: city-wide movement, connects districts, carries transit trunk routes
Collector (3,000-15,000 ADT)
ROW: 22-30m
Lanes: 1-2 per direction (3.0-3.3m each)
Design speed: 30-40 km/h
Transit: on-street bus stops with boarding islands
Cycling: protected bike lanes or buffered bike lanes
Pedestrian: generous sidewalks 2.4-3.6m
Median: optional, 1.8-3.0m where present
Role: connects neighborhoods to arterials, local commercial corridors
Local Street (<3,000 ADT)
ROW: 15-22m
Lanes: 1 per direction (2.7-3.0m each)
Design speed: 30 km/h
Transit: typically no fixed-route transit
Cycling: shared lane markings (sharrows) or separated bike lanes depending on context
Pedestrian: standard sidewalks 1.8-2.4m
Parking: parallel one or both sides
Role: neighborhood access, residential frontage, low-speed environment
Shared Street / Woonerf (<1,000 ADT)
ROW: 8-15m
Lanes: single surface, no lane markings
Design speed: 10-20 km/h
Cycling: shared surface, cyclists and pedestrians together
Pedestrian: priority over vehicles, no curb separation
Surface: textured paving, bollards, planters as speed controls
Role: residential living streets, market streets, festival routes
Pedestrian Priority Street (variable ADT, typically <500)
ROW: variable (4-20m)
Vehicles: no through-traffic, emergency and service access only
Design speed: 5-10 km/h (service vehicles only)
Surface: high-quality paving, level, no curbs
Role: retail promenades, civic spaces, historic cores
Contextual Modifiers
Apply these modifiers after primary classification to adjust cross-section priorities:
Context
Modifier
Commercial / Retail
+1.2-2.4m sidewalk width, continuous retail frontage, on-street parking or loading zones, wider furnishing zone for outdoor dining
Residential
Prioritize tree canopy coverage (>40%), reduce travel lane widths to minimum, add traffic calming, reduce noise through surface treatment
Mixed-Use
Adaptive curbside management (flex zones for parking/loading/transit by time of day), wider pedestrian zones at ground-floor retail
Industrial / Logistics
Wider travel lanes (3.3-3.6m) for trucks, larger corner radii, reinforced pavement, limit pedestrian/cyclist exposure to truck movements
School Zone
20-30 km/h speed limit, raised crossings at every intersection, flashing beacons, wide clear sidewalks, no on-street parking within 30m of entrance
Hospital / Institutional
Accessible design priority, generous drop-off zones, clear wayfinding, audible pedestrian signals, level surfaces throughout
Historic District
Narrower ROW acceptable, special materials and furnishings, heritage lighting, preservation of existing tree canopy and setbacks
Waterfront / Park Edge
Wider promenade (4.5-6.0m+), separated multi-use path, enhanced landscape buffer, view corridor preservation

Cross-Section Design Methodology
Design cross-sections layer by layer, working from the building face toward the street centerline. Each layer has a defined function and dimensional range.
Layer Sequence (Building Face to Centerline)
BUILDING FACE
|
|--> [A] Building Setback (context-dependent)
|--> [B] Frontage Zone (0.3 - 0.9m)
|--> [C] Pedestrian Clear Zone (1.8 - 3.6m)
|--> [D] Furnishing / Planting Zone (0.6 - 1.8m)
|--> [E] Cycle Track + Buffer (optional: 1.5-2.5m track + 0.3-0.6m buffer)
|--> [F] Parking Lane (optional: 2.1 - 2.4m parallel, 4.5-5.5m angled)
|--> [G] Travel Lane(s) (3.0 - 3.3m each)
|--> [H] Median (optional: 1.2 - 6.0m)
|
CENTERLINE (mirror layers G through A for opposite side)
Layer Definitions
[A] Building Setback
Not part of the public ROW but affects street enclosure. Zero setback for urban retail frontage, 1.5-3.0m for residential, 3.0-6.0m+ for suburban or institutional.
[B] Frontage Zone (0.3 - 0.9m)
The strip immediately adjacent to the building face. Accommodates door swings, window displays, awning drip lines, basement vault covers. In commercial areas, may include outdoor dining or merchandise display (with permit, requiring wider dimension of 1.2-2.4m).
[C] Pedestrian Clear Zone (1.8 - 3.6m)
The unobstructed walking path. This is the most critical pedestrian dimension. No street furniture, signs, trees, or other obstructions. Minimum 1.8m allows two wheelchairs to pass. Recommended 2.4m for residential, 3.0m for commercial, 3.6m+ for high-volume pedestrian areas. Must comply with ADA/accessibility requirements: maximum cross-slope 2%, smooth and continuous surface.
[D] Furnishing / Planting Zone (0.6 - 1.8m)
Contains street trees, light poles, sign posts, parking meters, benches, trash receptacles, bicycle racks, utility access covers. Serves as a buffer between pedestrians and the roadway. Tree wells minimum 1.5m x 1.5m, continuous tree trench preferred. Bioswales and rain gardens can be integrated here.
[E] Cycle Track + Buffer (optional)
One-way protected bike lane: 1.5m minimum, 2.0m recommended, 2.5m for high-volume. Two-way cycle track: 2.4m minimum, 3.0m recommended, 3.6m+ for high-volume. Buffer between cycle track and travel/parking lane: 0.3m minimum (painted), 0.6m recommended (with vertical elements such as bollards, planters, or curb).
[F] Parking Lane (optional)
Parallel parking: 2.1m minimum, 2.4m recommended (allows door opening without encroaching on bike lane). Angled parking (45-degree): 4.5-5.5m. Angled parking (60-degree): 5.2-5.8m. Perpendicular parking (90-degree): 5.5-6.0m. Consider flex zones: parking by day, loading in morning, outdoor dining in evening.
[G] Travel Lane(s)
General travel lane: 3.0m minimum urban, 3.3m standard (NACTO). Bus/transit lane: 3.3-3.6m. Right-turn lane: 2.7-3.0m. Left-turn lane: 3.0-3.3m. Never exceed 3.6m for any urban lane (wider lanes induce higher speeds). Reduce to 2.7m for yield streets and very low-speed environments.
[H] Median (optional)
Pedestrian refuge: 1.8m minimum (2.4m with accessibility), allows stroller or wheelchair to wait. Landscaped median: 2.4-6.0m, with trees, ground cover, stormwater management. Transit median: 3.6-5.0m for center-running BRT/LRT with platforms. Left-turn pocket in median: 3.0-3.3m wide, 30-45m long.

Intersection Design
Compact Intersection Principles
Design intersections to be as compact as possible. Smaller intersections reduce pedestrian crossing distances, slow turning vehicles, improve sight lines, and reduce conflict points. Key principles:
Minimize curb radii (tightest feasible for design vehicle)
Eliminate unnecessary turn lanes
Use curb extensions (bulb-outs) to shorten crossings
Align crosswalks with pedestrian desire lines
Provide pedestrian refuge islands for crossings >3 lanes
Set back stop bars 1.2-2.4m from crosswalk (4.0m at signalized with bike box)
Curb Radius Standards

Note: Effective turning radius is often larger than the physical curb radius due to parking lane and bike lane setbacks. A 3.0m physical curb radius with a 2.4m parking lane yields an effective radius of approximately 7.5m, sufficient for buses and delivery trucks.

Street Tree Selection Criteria
Select species based on all of the following:
Canopy spread
: minimum 6m mature spread for shade, 8-12m for boulevards
Root behavior
: non-invasive root systems, deep-rooting species preferred, avoid surface root species near pavement
Climate suitability
: USDA hardiness zone compatible, drought tolerance for urban heat island, salt tolerance for winter-maintained streets
Clearance
: minimum 2.4m trunk clearance (pedestrian), 4.2m over bike lanes, 4.5m over roadways
Soil volume
: 15-20 cubic meters per tree minimum for healthy growth (use structural soil, silva cells, or continuous trenches)
Maintenance
: deciduous preferred for seasonal solar access, avoid messy fruit species over sidewalks, disease-resistant cultivars
Spacing
: 6.0-9.0m on center for continuous canopy, stagger with light poles

Green Infrastructure Integration
Tree trenches
: Continuous below-grade soil cells connecting multiple tree pits, shared soil volume, structural support for pavement above
Bioswales
: Located in furnishing zone or median, 0.6-1.8m wide, 150-300mm deep, planted with native grasses and sedges, accept road runoff through curb cuts
Permeable paving
: Use in parking lanes and furnishing zones, reduces runoff by 70-90%, requires regular vacuum sweeping
Rain gardens
: At curb extensions and median ends, capture and filter first flush of stormwater, sized for local rainfall intensity
Stormwater planters
: Contained planting areas with underdrains, suitable where infiltration is not feasible (high water table, contaminated soil)
Traffic Calming Toolkit
Measures by Target Speed Reduction
50 to 40 km/h (Arterial/Collector Transition)
Road diet: convert 4 lanes to 3 (2 travel + center turn lane), reclaim space for bike lanes and wider sidewalks
Curb extensions at intersections: narrow roadway from 12m to 9m at crossing points
Median islands: 1.8m minimum width, planted, with pedestrian refuge
Signal coordination at 40 km/h progression speed
Roadway surface change at gateway (asphalt to textured)
40 to 30 km/h (Collector/Local Transition)
Chicanes: alternating curb extensions that deflect the travel path laterally, 3.0-3.6m deflection
Raised crossings: full-width speed tables at pedestrian crossings, 75-100mm height, 6.0m long platform
Speed tables: flat-topped speed bumps, 6.0-7.5m long, 75-100mm height
Gateway treatments: visual and physical narrowing at neighborhood entries
Neckdowns: narrow roadway to one lane at pinch points, with priority signs
30 to 20 km/h (Local/Shared Street Transition)
Pinch points: narrow roadway to 3.0-3.6m, one vehicle at a time, yield condition
Raised intersections: entire intersection at sidewalk level, vehicles mount gentle ramp
Horizontal deflection: S-curves using alternating parking or planting islands
Surface material changes: transition from asphalt to unit pavers, textured concrete
Vertical elements: trees, bollards, planters placed to reduce apparent width
20 to 10 km/h (Shared Street / Woonerf)
Shared surface: remove curbs entirely, single-level surface
Textured paving: cobblestone, unit pavers, or stamped concrete to create visual and physical friction
Removable bollards: allow event closure and emergency access while defining edges
Planting and furniture: place obstacles (planters, benches, play elements) in the vehicle path
Tight geometry: no straight runs longer than 30-50m
