Abstract:
Abstract. Based on the monthly datasets, including the number of traffic accidents, casualties and meteorological data, the relationship between the traffic accidents and meteorological conditions is studied. The results are as follows: (1) There are two peaks of the number of traffic accidents, which are the saddle-shaped peak from Apr to Jun and the second peak in Oct respectively. The number of traffic accidents in February is the least. The temporal distribution of the casualty is different from that of traffic accident. Most casualties happened in Jul. and the second in Apr. and Oct. The susceptibility of traffic accident and casualty in Hebei, Beijing and Tianjin decreased successionally from high to low. (2) A new result is obtained: in comparison with the number of traffic accidents, the correlation between meteorological condition and casualty is higher. The main reason is that the adverse weather conditions always cause drivers fail to control the vehicle or to make right decision. Therefore, the accident causing casualty should be focused on while the monthly weather-related accident is discussed. (3) The correlation coefficient between the number of casualty and precipitation or relative humidity is significantly positive. Otherwise, the correlation coefficient between the number of casualty and visibility or pressure is significantly negative.
