Introduction
Road traffic accident inspection and identification is an important link in the accident handling procedure, and vehicle speed identification is an important technical method among them:
The analysis of the cause of the accident and the determination of the responsibility for the accident have an important supporting role in evidence: Vehicle speed identification can be based on dynamics theory, empirical formula, model
Methods such as quasi-test, simulation reproduction, vehicle driving recorder, vehicle event data recording system, and video images are suitable for vehicle speed identification:
Select the appropriate method according to the accident form and inspection material conditions, and cross-validation should be carried out if the application requirements of multiple identification methods are met: GA/T 1999
It was formulated to guide the selection of vehicle speed identification methods, standardize the identification requirements, identification steps and methods for vehicle speed identification in road traffic accidents:
Appraisal opinion:
GB/T 33195-2016 "Vehicle Speed Appraisal in Road Traffic Accidents" is the universal and basic
Standard, GA/T 1999 "Vehicle Speed Appraisal Method for Road Traffic Accidents" is a supplement and detail to the appraisal method in GB/T 33195-2016
GA/T 1999 is proposed to be composed of three parts:
--- Part 1: Based on the vehicle tachograph: Aiming at ensuring the speed identification of vehicles in road traffic accidents based on vehicle travel recorders
The scientificity and accuracy of the determined results:
--- Part 2: Based on the vehicle event data recording system: Aiming at guaranteeing the safety of road traffic accidents based on automotive event data recording systems
Therefore, the scientificity and accuracy of the vehicle speed identification results:
--- Part 3: Based on video images: A science aimed at guaranteeing the results of vehicle speed identification in road traffic accidents based on video images
sex and accuracy:
Appraisal Method of Vehicle Speed in Road Traffic Accidents
Part 2: Recording system based on vehicle event data
1 Scope
