**Results Accident analysis (1)*:**

ca. 80 % of accidents from this accident type lead to personal injury

à

The personal injury is 6-time higher than for all accidents

à

36 % of turning-off accidents lead to personal injury

à

15 % of cycling accidents lead to personal injury

à

7 % of all accidents lead to personal injury

Results Results Accident analysis (4):

• 2/3 right-turning accidents, 1/3 left-turning accidents

• Main causer is the car driver (>90%)

• Most frequent accident cause is cycling on the pavement or in wrong

direction (in total 12%)

• High risk for cyclists 21 – 34 years old

• High risk for car drivers 18-20 ; > 65 years old

* Cause of accidents with cyclists in German accident statistics (destatis): 4.0 %

** Cause of accidents with cyclists in German accident statistics (destatis) „cycling on

wrong infrastructure or in wrong direction“: 11.5 %

•High safety level at roundabouts designed in accordance with the

guidelines

•Mixed traffic on the roundabout‘s circular roadway ist the safest

arrangement for cyclists, even if traffic volume is high

•Cycle paths with priority are the least safe form of guidance of

bicycle traffic

•The width of deflection in accordance with the guidelines

•According to Section 37 the German General Administrative

Regulations on the Road Traffic Regulations“ (VwV-StVO),

situations in which traffic signals are necessary include

those where accidents frequently happen because visibility

is restricted and there is no possibility of improving visibilty

or prohibiting traffic which is crossing or entering the road, and

those where frequent infrigements of rigth-of-way without this

being difficult to identify or with the right-of-way being difficult to

unterstand.

•The VwV-StVO, sections 39 through 43):

The free flow of traffic is to be upheld using the means available.

In applying this principle, the safety of all road users takes

•The German Guidelines for Traffic Signals (RiLSA 2010):

Traffic signals are installed to „increase traffic safety and/or to

improve the quality of traffic flow.“
