Илиев А. Г., Трусова Т. В. Traffic Management in the Locations of Frequent Accidents in the Dark // Молодой ученый. — 2013. — №1. — С. 10-14.

Statistics of road accidents in many countries including Russia shows that their risk greatly increases in the period of darkness. Despite the fact that traffic during this period is 5–10 times less intensive than in the daytime, the share of accidents is 40–60 per cent of their total number.

Accidents in the dark are characterized by more severe consequences. The main reason for the increased risk of driving at night is a sharp decrease in the efficiency of visual perception by drivers of the road and the environment caused by physiological characteristics of human sight.

Statistical analysis of Rostov region for the period of 2009–2011 has shown that more than half of the road accidents take place in the daytime (tab. 1).

Percentage distribution of accidents by the time the day is shown in Figure 1.

The total number of daytime accidents exceeds 60 per cent. Nevertheless the consequences of night accidents are more serious (tab.2).

The intensity of traffic at night is significantly reduced. However, in the dark time more than 50 per cent of people are killed in road accidents (Fig. 2). It proves the ineffectiveness of measures taken to manage road traffic at night, which results in the formation of different locations where road accidents occur most frequently.

To achieve maximum effect while taking measures to manage traffic in the dark time the sections of the road network with similar road conditions, on which the number of road accidents exceeded the average value were considered [2, p.34]. Quantitative analysis [1, pp.42–47] showed that the coefficient of relative accident rate (Ka) is of progressive nature. In order to find out road conditions, which contribute to the formation of areas of concentration of road accidents, the methodical recommendations were followed to propose measures to improve road safety on those sections of the road.

The areas of concentration of road accidents are found out making use of the method of successive approximations, which provides the highest accuracy of identification of such areas if there is complete (up to a meter) information about the location of an accident and the information about the average daily intensity of traffic during a year.

This technique also allows to define the character of locations of road accidents concentration (progressive, stable, regressive), to determine the degree of danger.

Based on the data processed, it can be concluded that the areas of concentration of road accidents in the hours of darkness and in the daytime are different. Therefore, there are different reasons of formation of such road sections. The reasons of concentration of accidents in the dark time can also be defined. They are:

  • The loss of the visual smoothness of the motorway and uncertainty as to the road ahead;

  • The deterioration of the optical orientation due to the lack of road marking or its excessive wear [3, p.44];

  • Lack of the stationary lighting resulting in reduced visibility of the roadway and other objects [4, pp.178–182];

  • Sections of the road or street network where there is no stationary lighting from two or more consecutive lighting supports [4, pp.211–217];

  • Local narrowing of the carriageway;

  • Mismatched dislocation of road signs, markings. Roadside environment that causes the exceeding of speed limit on the main streets [5, pp.123–128].

To reduce the accident rate it is necessary to take new measures that proved to be very effective in the European countries and the United States of America. A comparative analysis of these measures is shown in figures 3 and 4.

The comparative analysis shows that:

  • Traffic management in the areas of concentration of road accidents at night is still imperfect because of the failure to comply with the normative requirements for the implementation of measures concerning traffic management and low efficiency of measures taken which is proved by the data above;

  • There are no specific recommendations for the implementation of measures at the sections of road network with various road conditions in the dark time;

  • There are no wide studies to determine road conditions related to road accidents, which are sure to be taken into account while developing measures and implementing them;

  • There are no experimental results to determine the degree of influence of the main factors of road conditions related to the accident in the dark;

  • There are no data to determine the degree of influence of reflective elements on the optical orientation of the driver in the dark;

  • There are no data to determine the degree of influence of LED lighting on the accident rate in the dark.
