A task for the police =
the accident report
Reasons for the accident report and analysis:
•
•
•
•
Removal of dangerous situations or objects caused by the accident
Investigation of criminal offences or misdemeanours
Statistical analysis of accidents, finding blackspots and identifying
contributing factors and eliminate deficits in road infrastructure
Providing civil law claims
Overall objektive: Avoiding accidents with safer roads!
3
What exactly does the term
roadsafety mean?
Thesis I
•
As opposed to sensations like warm/cold or light/dark, road safety is
not tangible,
As -
•
it is the number of accidents, the following investigations of the site
and the traffic situation, which allows us to realize the safety of a road.
4
Accidental accidents?
Thesis II
• road accidents do not happen “by accident”.
As –
• it cannot be solely the fault of the drivers, if a large number of different
road users keep making the same mistake at the same site,
•
in this case something is wrong with the site respectively road itself.

Accident report - registration
of statistically crash data
Data content for the accident investigation:
• classification
• data regarding the site
• description of the accident
• personal data, vehicle data
7
Classification
Road accidents are reported using 3 different criteria:
:
•
accident type (7 types)
Conflict situation directly before to the accident
8
Types of accidents
1 Driving accident (D) Fahrunfall (F)
2 Turning-off accident (TO) Abbiege-Unfall (AB)
3 Turning-into/crossing accident (TC) Einbiegen/Kreuzen-Unfall (EK)
4 Crossing-over accident (CO) Überschreiten-Unfall (ÜS)
5 Accident caused by stopping/parking (SP) Unfall durch ruhenden Verkehr (RV)
6 Accident in longitudinal traffic (LT) Unfall im Längsverkehr (LV)
7 Other accidents (O) Sonstiger Unfall (SO)
9
Classification
:
•
•
kind or sort of accident (10 kinds)
Description of the circumstances of the accident
10
Kinds of accidents Unfallarten
1 = Collision with a starting / stationary vehicle
Zusammenstoß mit anfahrendem / anhaltendem / ruhendem Fahrzeug
2 = Collision with a vehicle ahead (driving or waiting)
Zusammenstoß mit vorausfahrendem / wartendem Fahrzeug
3 = Collision with a vehicle going in the same direction
Zusammenstoß mit seitlich in gleicher Richtung fahrendem Fahrzeug
4 = Collision with an oncoming vehicle
Zusammenstoß mit entgegenkommendem Fahrzeug
5 = Collision with a crossing vehicle
Zusammenstoß mit einbiegendem / kreuzendem Fahrzeug
6 = Collision between vehicle and pedestrian
Zusammenstoß zwischen Fahrzeug und Fußgänger
7 = Collision with obstacles on the road
Aufprall auf Fahrbahnhindernisse
8 = Leaving the lane to the right
Abkommen von der Fahrbahn nach rechts
9 = Leaving the lane to the left
Abkommen von der Fahrbahn nach links
0 = Other type of accident
Unfall anderer Art
11
Classification
:
•
•
•
kind or sort of accident (10 kinds)
Description of the circumstances of the accident
accident category（6 categories）
Description of the consequences
( fatal accidents, serious injuries, light injuries and damage)
12
Accident category / Severity
Unfallkategorie
1 = Fatal accident (killed person)
Unfall mit Getöteten
2 = Accident with serious injuries
Unfall mit Schwerverletzten
3 = Accident with light injuries
Unfall mit Leichtverletzten
4 = Serious accident with property damage
schwerwiegender Unfall mit Sachschaden
5 = Other types of damage; no influence of alcohol
sonstiger Sachschadensunfall ohne Alkoholeinwirkung
6 = Other kinds of accidents with property damage; drivers under
the influence of alcohol or other substances
sonstiger Sachschadensunfall unter Alkoholeinwirkung und anderer
berauschender Mittel

• classification
14
Data relating to the site of the accident
Daten zum Unfallort
• Area （urban, non urban)
Ortslage (iO, aO)
• Driving direction (ascending, desdending)
Fahrtrichtung (aufsteigend, absteigend)
• Characteristics of locatation（crossing、indention、slope、turn)
Charakteristik (Kreuzung, Einmündung, Gefälle, Kurve…)
• Specific features ( pedestrian crossing, bus stop）
Besonderheiten (Fußgängerüberweg, Haltestelle…)
• Road conditions ( dry, wet, moist, icy or slippery)
Straßenzustand (trocken, nass/feucht, winterglatt…)
• Light conditions（daylight、darkness、twilight）
Lichtverhältnisse (Tageslicht, Dunkelheit, Dämmerung)
• Localiation of the accident ( kilometres, geographical information)
Genauer Unfallort (Km-Angaben, geographische Info.)
15
Data relating to the site of the accident
This data is neccessary for the accident investigation for the following reasons：
• Identification of similarities refering to the location
Feststellung von Gemeinsamkeiten an der Örtlichkeit
• Contributiing factors
Begünstigende Unfallumstände
16
• classification
17
Description of the accident
Unfallbeschreibung
• textual description of the accident details
•
accident sketch
•
pictures
18
Accident diagram
Unfalldiagramm
19
• classification
20
Personal data and vehicle data
Statistics relating to personal data:
:
•
age, sex, degree of injury
•
vehicle used ( passenger car, truck, motorbike, bicycle...
•
cause of theaccident (alcohol, right of way, speed...）
•
date of driving license
General statistics regarding the vehicle：
:
•
license plate, amount of damage, insurance data
•
number of passengers
21
Problems with the compilation of data
•
time pressure – leads to a quick, superficial and possibly incorrect data input
•
lack of knowledge concerning accident statistics – prompts people to
underestimate certain statistical determination and distinction
•
lack of knowledge concerning the needs for accident investigation – results
in inadequate description of the accident site
•
lack of knowledge concerning aggregation of accident data results in
incorrect lacalization -> the only person who was on site during the accident
can truly localize it.
22
Situation description by
type of accident
• unsuitable = the kind of accident – just 10 different kinds to chose from,
but few are fully applicable
• unsuitable = the category of the accident – Consequences of accidents
are relatively coincidental and becomíng less and less severe due to
improvement in emergency services and the safety features of the
vehicles themselves.
• suitable = the type of accident – this classification describes the situation
before the accident occurred, i.e. the traffic situation and interaction of
road users, which is actually based on rules, laws and regulations.
23
Types of accidents Unfalltypen
1 Driving accident (D) Fahrunfall (F)
2 Turning-off accident (TO) Abbiege-Unfall (AB)
3 Turning-into/crossing accident (TC) Einbiegen/Kreuzen-Unfall (EK)

6 Accident in longitudinal traffic (LT) Unfall im Längsverkehr (LV)
7 Other accidents (O) Sonstiger Unfall (SO)
24
Turning-off accident
Abbiege-Unfall
•
The accident was caused by a conflict between a turning vehicle and
another vehicle (or even a pedestrian) travelling in the same or
opposite direction at an intersection, junction, or an entrance to a
property/car park.
Der Unfall wurde ausgelöst durch einen Konflikt zwischen einem Abbieger und einem
aus gleicher oder entgegengesetzter Richtung kommenden Verkehrsteilnehmer (auch
Fußgänger) an Kreuzungen, Einmündungen, Grundstücks- oder Parkplatzzufahrten.

Work of the accident committee
Tasks of the accident committee
• Police
• Road traffic authority
• Road construction authority
In an local accident investigation on site:
:
• finding black spots according to criteria and thresholds
• identifying deficits in the road infrastructure and contributing factors
• taking measures to mitigate black spots

so far
= no accidents
Conclusion:
Accident costs 2004 – 2006 (134.000,- € x 3 years)
= 402.000,- €
Investment costs stationary speeding measurement
= 15.000,- €
Accident costs, which could be avoided
from 2007 to 2012 (134.000,- € x 6 Years)
= 804.000,- €
