Active transport (walking, cycling) and public transport infrastructure design has become a core part of Australian road and urban design practice, guided primarily by Austroads Guide to Road Design Part 6A (Pedestrian and Cyclist Paths) and jurisdiction-specific bicycle/pedestrian strategies.
Cycling Infrastructure Types
| Facility Type |
Description |
Typical Application |
| Shared path |
Shared by pedestrians and cyclists, separated from traffic |
Recreational routes, lower-volume corridors |
| On-road painted bicycle lane |
Marked lane within the carriageway |
Lower-speed, lower-volume roads |
| Separated cycleway (kerb/median protected) |
Physically separated from traffic |
Higher-speed or higher-volume roads |
| Bicycle boulevard / quiet street |
Traffic calmed local street prioritising cyclists |
Local area cycling networks |
Design Parameters: Cycling
| Parameter |
Typical Value |
| Design speed (cyclist) |
20–30 km/h (up to 40+ km/h downhill) |
| On-road bicycle lane width |
1.5–2.0 m |
| Separated cycleway width (one-way) |
1.5–2.5 m |
| Separated cycleway width (two-way) |
2.5–4.0 m |
| Minimum horizontal clearance to hazards |
0.5 m+ |
Cyclist Sight Distance and Stopping Distance
Similar concept to vehicle stopping sight distance, but with different speed, reaction time, and braking assumptions appropriate to cyclists.
Pedestrian Infrastructure
| Element |
Guidance |
| Footpath width |
1.5 m minimum (residential); 2.0–3.0 m+ (commercial/high pedestrian volume) |
| Kerb ramps |
Compliant grades and tactile ground surface indicators (TGSIs) per AS 1428.1 |
| Crossing treatments |
Zebra, signalised, wombat crossing (raised), refuge islands |
| Pedestrian level of service |
Based on flow rate vs effective footpath width |
Accessibility (AS 1428.1: Design for Access and Mobility) is a mandatory consideration, not an optional extra, for all pedestrian infrastructure.
Public Transport Infrastructure
Bus Stops and Interchanges
| Element |
Consideration |
| Bus stop type |
Kerbside, indented (bus bay), or boarding island |
| Stop spacing |
Balance access (closer stops) against travel time (fewer stops) |
| Accessible boarding |
Kerb height/DDA-compliant boarding for low-floor buses |
| Bus priority |
Queue jump lanes, transit lanes, signal priority |
Bus Priority Measures
| Measure |
Effect |
| Dedicated bus lane |
Removes buses from general traffic congestion |
| Transit lane (T2/T3) |
Shared with high-occupancy vehicles |
| Queue jump lane |
Short bus-only lane at signals to bypass queued traffic |
| Signal priority (active/passive) |
Extends green or shortens red for approaching buses |
Integration and Network Planning
Active transport and public transport design is most effective when planned as an integrated network rather than isolated links:
- First/last mile connectivity: safe walking/cycling routes to public transport stops
- Directness and legibility: routes should be as direct as the road network allows, not indirect detours
- Connectivity across barriers: dedicated crossings of arterial roads, rail corridors, and waterways
Practical Notes
- Perceived safety (separation from traffic, lighting, overlooking) drives cycling uptake more strongly than raw travel time in most Australian contexts: a technically compliant but exposed on-road lane will often see low usage.
- Footpath and crossing accessibility (AS 1428.1) should be designed in from the outset: retrofitting compliant tactile indicators and ramps is more expensive and disruptive than incorporating them in the original design.
- Bus priority measures deliver the largest travel-time benefit at the specific pinch points causing delay (signals, queued approaches): a general-purpose transit lane along an already free-flowing corridor delivers comparatively little benefit.
