At 50 km/h 3
out of 10 are
killed
But at 60 km/h
7 out of 10 will
die
WHY VULNERABLE?Death risk for pedestrians
CONSIACONSIA
CYCLISTS ARE AT RISK
The risk per km is four times higher for cyclists than cars
• Is this a reasonable risk number?• Risk per trip?• Replace a car trip?• Include public transport?

So it is not four times as risky to bike – it is ten times!
CONSIACONSIA
INFRASTRUCTURE FROM PLANNING STAGE
Town planning and traffic planning should be considered as one
Mobility plans A bicycle plan with a functional
classification of networks is a good starting point
CONSIACONSIA
COHERENT
The network must be coherent and connect important points for cyclists
Lack of coherence is perceived as a detour
CONSIACONSIA
SAFER BICYCLE NETWORKS
Make bike paths where vehicles travel more than 40km/h
On street where speeds are under 40km/h adjust volume and speeds of cars
Meticulously redesign points where cyclists cross car traffic
Safe design of conflict points between vulnerable road users (at bus stops or between fast and slow cyclists)
CONSIACONSIA
SHARING THE STREET
Cyclists may share the street with motor vehicles or pedestrians
Keywords are speed and volume
CONSIACONSIA
BICYCLE PATHS
Safest solution: one-directional at both sides of the street
Not bi-directional along a city street

GEOMETRY
Widths Uni-directional Bi-directional Bike lane Shared path Common path Sharing bus lane
Uniformity
CONSIACONSIA
BICYCLE PATH
2.2m (1.7m)
CONSIACONSIA
SHARED PATH
1.7m (1.5m)
CONSIACONSIA
BICYCLE LANE
1.5m (1.5m)
Often problems with parking
CONSIACONSIA
BI-DIRECTIONAL PATHS
Not in urban areas
Dividers – but not at junctions
2.5m
Min. 1.0m
CONSIACONSIA
MORE THAN LANES
Facilities for parking
CONSIACONSIA
UNIFORMITY
Keep design of path along street
CONSIACONSIA
MAINTENANCEEven surface very important for the use of the path
Regular maintenance
Snow removal at same time or earlier than on roads
After works in the path it should be restored as new
CONSIACONSIA
ROAD SAFETY INSPECTION
Bicycle path along Aksu Caddesi, Ekrem Kurt Blv. and Çobançeşme Koşuyolu Cd. from the interchange with Kennedy Cd. to the interchange with D-100 Yanyolu in Istanbul
Inspected September 2013 3km Bi-directional eastern side of road
CONSIACONSIA
BI-DIRECTIONAL PATH
All junctions are signal-controlled
Dedicated signals for cyclists
Separated from vehicle traffic
CONSIACONSIA
Exit from parking lot crosses the bi-directional cycle path
CONSIACONSIA
Cycle track blocked by stopping and parking vehicles
Cycle
CONSIACONSIA
THREE DIFFERENT SIGNALS FOR CYCLISTS

SLIP LANE ALLOWS FOR HIGHER SPEEDS

CYCLING
Cycling is a serious mode of transport – not just leisure
Should be treated as other modes
