The Analysis And Applied Research Of Traffic Accident Velocity Calculate Method

In recent years, road traffic accidents to harm people is increasing, traffic accident analysis and research has become more pressing and important. Vehicle speed and trajectory is the main content of the technical analysis of traffic accidents, is also one of the main factors of traffic accidents. On the analysis of the traffic accident causes and treatment into must solve the practical problems in the traffic accident is the accident vehicles in traffic accident rate. Gather sufficient evidence to establish the correct vehicle collision model, an accurate description of the accident car accident during the state of motion, which are important computing speed accidents.This paper discusses the theoretical basis to the collision dynamics of the car crash one-dimensional and two-dimensional model of the collision, one-dimensional collision model is divided into front and rear-end collision of two forms of the collision, the collision of two-dimensional model is divided into two-dimensional central collision and two dimensional non-central collision of two forms. In a simplified mechanical model of rational basis, select the method and scope of calculation of four models and related parameters were careful discussion and analysis of the various models of the calculation process are summarized, and their conditions of use explained. Due to the accident scene marks, evidence of the accident investigation to identify the role of irreplaceable, this paper, the actual experience of the accident scene investigation of the accident scene investigation process specifications were consolidated, and several conventional collision scene marks a detailed description of survey evidence. In calculating the speed required to analyze the overall effect of different factors on the movement of vehicles, in some of the more cumbersome vehicle collision accident calculation methods can be applied to a variety of mutual authentication. In this paper, from a large number of speed calculation and case analysis, with obvious braking mark and side mark, at the same time also have a lot of fallout collision accident, should be the preferred mark or side mark calculation formula to solve the vehicle braking speed, and then validated calculation method on the basis of analysis and optimization.
