Goal: On the basis of studying drivers’ visibility in the condition of using the front lights and the brake capacity of automotive, this paper aims to calculate the safety speed of automotive in that lighting condition and xperiments are needed to verify the results of theoretical calculation. | INTRODUCTION Nowadays cars are becoming a popular means of transport in the society which contributes to create a solid basis for the human progress and civilization. However apart from the huge benefits cars also cause considerable problems for human people s life. Annually there are about over five million victims of severe traffic accidents in the world. According to reports of many countries economical losses aused by road traffic accidents have achieved 1 to 2 of annual GDP. Obviously where and when there are people participating in traffic there is danger of traffic accidents. Thus traffic accidents have become a burning issue in societies. Vietnam is one of the countries having the highest mortality due to traffic accidents above the total number of transport means in the world. Particularly in the recent years there has been a sharp increase of the total number of traffic accidents as the result of the rising number of transport means and traffic flows. This trend still has no sign of reduce. On that basis the implementation of the thesis topic Automotive Movement safety at night when using front lights remains its necessity which has important scientific and practical meaning. Goal On the basis of studying drivers visibility in the condition of using the front lights and the brake capacity of automotive this paper aims to calculate the safety speed of automotive in that lighting condition. Experiments are needed to verify the results of theoretical calculation. Scope of study - Types of Transport means Cars and trucks are in line with technical standards and regulation of Vietnam - Operating Conditions Cars operated in night front lights used no street lights at the work road drivers conduct brake when recognizing pedestrians crossing the road in order to prevent accidents Study method There is a combination of theoretical and empirical research. Scientific contribution - The thesis studies a new issue in Vietnam from both the theoretical and empirical .
