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

BI-DIRECTIONAL PATHS

Not in urban areas

Dividers – but not at junctions

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

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

CYCLING

Cycling is a serious mode of transport – not just leisure

Should be treated as other modes
