| 摘要： | The widening and improvement of highways in India has not resulted in safe travel. The speeds on highways are going up resulting in increased fatal and severe crashes. Many researchers have developed predictive models for road accidents but in most of the models speed was not chosen as an explanatory variable. This may be a case in developed countries where speed distributions on the road are comparatively uniform but in mix traffic condition like in India, the effect of speed related variables on accidents need to be studied. The present work was designed to study the impact of various speed related variables on road accidents. The speed data was collected on 11 sections of highways. The accident data on these sections for three years was collected from police records and for analysis the accident rate (accidents/km/year) was plotted against various speed related variables. Accident prediction model including average speed, standard deviation of speed and percentage of vehicles travelling at modal speed as explanatory variables, was found most significant. The results indicated that accidents increase rapidly with increase in speed and speed dispersion. Number of accidents fall sharply as percentage of drivers travelling at modal speed increases but increase with increasing proportion of slow or fast moving traffic. |
