Impact Analysis of Urban Road Traffic Accidents Based on Water Wave Principle

Abstract

The existing research results on the impact of urban road traffic accidents mainly focus on the impact scope and duration of traffic accidents, and the research method is based on the traffic flow theory of fluid mechanics. The theory assumes that the traffic flow is in a confined space and there are many entrances and exits and nodes in the urban road network, which is inconsistent with the actual situation. The impact of urban road traffic accidents on traffic is consistent with ripple phenomenon, so the water wave principle is used to quantitatively analyze the impact degree of urban road traffic accidents on traffic. First of all, the impact of urban traffic accidents on traffic and the ripple phenomenon of water surface interference are compared and analyzed. On this basis, the concept of traffic impact coefficient is put forward, and the characteristic curve of traffic impact coefficient is drawn by using the speed data obtained from investigation. Using SPSS software and water wave equation, the relationship model of traffic impact coefficient with time is established. The results show that the fitting degree of the model is good and has statistical significance.
