3.  Accident Type – Collision Type…
… an Historical Issue : 2 variables in CARE
- Accident Type :
- A - Accidents with pedestrians + 3 levels
- B - Accidents with parked vehicles + 3 levels
- C - Single vehicle accidents + 3 levels
- D - At least two vehicles - no turning + 3 levels
- E - At least two vehicles - turning or crossing + 3 levels
- Collision Type :
- collision with (animal, pedestrian, obstacle)
- type of collision (chain, rear, lateral, frontal)
+ nb of pedestrians, nb of vehicles…

.
 7 values
A-10 SINGLE VEHICLE ACCIDENTS
.
 15 values

6.  Mapping CADaS – Member States
Not so easy to make a Good Quality Mapping
Source data are very detailed
or
Source data are at low level
!in some cases even not possible because of totally different perception

7.  We can deduce this information
A-8 : ACCIDENTS WITH PEDESTRIANS
NB of pedestrian >=1
U-11 : TRAFFIC UNIT MANOEUVRE (Crossing (on
pedestrian crossing), Walking on the carriageway ...)
A-9 : ACCIDENTS WITH PARKED VEHICLES
NB of Vehicles = 1
U-11 : TRAFFIC UNIT MANOEUVRE (Parked)
A-10 : SINGLE VEHICLE ACCIDENTS
NB of Vehicles = 1
R-17 : OBSTACLES * (Obstacle, Animal, No obstacle…)
* : this variable will be adapted

8.  We can deduce this information
A-11 : AT LEAST TWO VEHICLES - NO
TURNING
A-12 : AT LEAST TWO VEHICLES - TURNING
OR CROSSING
NB of Vehicles >= 2
U-11 : TRAFFIC UNIT MANOEUVRE (Turning
right, Overtaking vehicle on its left, U turn...)

9.  Conclusion
Too much detailed information is not
adapted and easy to use for analysis
If needed, we are able to deduce it by
combining other variables
