Transcript of Cycling Infrastructure

Example of good and poor cycle path quality. Loncoln Park, Chicago
Surface Quality
Australian standards:
Asphalt surfaces free of cracks
Aggregate size of 10 mm or less
Surface imperfections such as pavement patches and cracks can make uncomfortable and unsafe
Standards for Bike Stands
Australian Standards
Only allow wheel to be locked to the rail
Allow
both
wheels and the frame to be secured to the bike parking rail.

Who uses the bike and how?

1.
Safety

2.
Direct

Short and rapid routes from origin to destination

3.
Comfortable

Good surface, generous space and little hindrance from traffic participants

4.
Attractive
An attractive and socially safe environment, without smell or noise inconvenience

5.
Cohesion
Logical and cohesive routes

Upright cycling postion
Large variety of users (Netherlands)
Active fast posture and mainly young males
5 aspects for a bicycle friendly infrastructure
Australia

Adequate bike width ensures:

Acceptable clearance from obstacles
Other cyclists can overtake
Increased comfort and safety for cyclists

Introduction
Separated bike path
With trees and raised curbs
Separated cycling paths are not necessarily safer than the ones which are painted on the road.

Convenience

- within 50 m from prime locations

Noticeable places
- sufficient passive surveillance
- promoting pro-cycling message






Examples of lane width in Melbourne, Australia
Locking Mechanisms
at Bike Share Station
Germany:

Secured with electronic lock
Calls customer service to get password
Types into bike's touch screen to release
Hangzhou Public Bicycle Share:
Secured with electronic lock
Smart-card technology
Automated check in and out


Bike Stands & Racks around City/Campus
1.
Security
against theft and vandalism
2.
Protection
from rain and weathering
3.
Convenience
to cyclists
4.
Promotes
cycling culture

Raised Cycle Track in USA
Materials used for colouring bike lanes:
Paint
Durable Liquid Pavement Markings
Thermoplastic
Or embedded using colour asphalt
Other sign types:
Confirmation signs
Turn signs
Decision signs
Raised cycle lanes:

Prevent motor vehicles parking on the lane
Minimizes maintenance costs due to limited motor vehicle wear
creates a dedicated space for cyclists, off of sidewalks








Raised bike lane in Portland, Oregon
Green painted slip lane on Macarthur St, Melbourne
Australia
Advantages of coloured lanes:
Highlights the bike lane to reduce conflict between bicycle and other vehicles
Improve visibility of cycling space, especially at intersections

Disadvantages of coloured lanes:
High installation costs
High maintenance costs

Guide bicyclists on a safe and direct path through intersections
Stripes should be 2 foots by 6 inches in size
Spacing between stripes should be 2 - 6 foots
Provide chevron or colour on the path
Green spray paint used to colour lane
Free for cyclists to turn right
Measurement
Parking Availablity
Taking Design into Consideration...
Efficient & Space-Saving Cyclepods
Stores 8 bikes in 4 meter squares
Compares to 7.2 meter squares for linear parking
2 locking points for both wheels and frame
User-Friendly
No fixed formula
Good practices include
Estimating based on bicycle mode share
Utilization surveys
Dynamic - monitor continuously and add additonal bike parking if funding allows
Many countries do not take the cyclists into account well enough (at Cross-Junctions)!
Cycling infrastructure shouldn’t be low in hierarchy compared to other infrastructure.
Self Repair Station
Australia
Directional signage:
Direct cyclists between surrounding road network and an off-road path
provide cyclists with the path name
provide information on direction and distances
provide the cyclist with names of intersecting roads/paths


Signage should provide clear way finding for riders using a particular route. Signs should be displayed at every junction or decision point
Bike sign in New South Wales, Australia
Australia
Functional hierarchy of a cycling route should enable direct, efficient and safe travel for cylists.
Australian Land Transport Network
Outlines two types of path hierarchy:
Major cycling routes
Greenways and cycling routes
Greenway cycle path
A dedicated walking and cycling rote which follows public transport corridors or other linear open space such as rivers.
Purpose:
Ensure low speed environment for cycling and walking
Connect quiet streets with aterial cycle paths
Create direct cycle routes and better access to public transport
Improved connection to open space
Greenway cycle path in Southern Australia
Major cycling routes
Provide a direct and continuous link to major centres and optimise cycling travel times.
Purpose:
Provide a space specifically for cyclists
Ensure sepaation between cyclists and motor vehicles
give priority for cyclists
