Although it is difficult to allocate resources for public road lighting, proper illumination greatly reduces the number of accidents. Studies have shown that drivers take greater risks in low-light conditions, as they overestimate their own abilities and fail to see other road users. Moreover, they tend to ignore the actions of other road users, making them more vulnerable to accidents. The amount of illumination recommended by the state depends on several key factors, including the type of road, surrounding environment, speed limit, and other factors.
In general, road accidents happen at night at disproportionately high rates. The darkness greatly impacts the ability and behaviour of drivers, impairing visibility and night vision. However, road lighting can counteract this effect. This article describes some of the benefits of road lighting. It outlines some of the ways it can improve road safety. Listed below are the five most important benefits of road lighting. Let's explore some of them. Let's begin by understanding how it works.
For example, one type of highway lighting is center-line highway lighting. It consists of a narrow central strip that divides the roadway longitudinally into two parts. In this scheme, the road is lit from both ends, reducing the need for additional lighting and maximizing savings for electrical conductors. This lighting system also darkens footpaths. The illumination should cover the pavement area between the kerbs, while also illuminating the adjacent area, 3 to 5 m beyond the edge of the pavement.
Another way to evaluate the effect of road lighting is by comparing RTCs in two areas: those with road lighting, and those without. Road-lighting research is important, as the results of these studies may not be representative of the effects of all road lighting. After all, if the streets are not well-lit, then the roads will be poorly lit. A poorly-lit street may cause accidents. The increased speed may be a result of other factors, such as poor weather conditions.
To determine the impact of road lighting, researchers have conducted a series of experiments. To determine the effect of road lighting, a straight two-lane section was chosen in Otaranta, Finland. The road was 300 metres long and six meters wide. The area was also marked with road markings. As the result of these experiments, we can see that road lighting has positive and negative effects on visibility and safety. The opposite is also true for the effect of car headlights.
Drivers' perception of the target contrast varies over time. Table 3 shows an approximate estimate of the target contrast. The values in parentheses indicate positive and negative contrast. Under 100% road lighting, the driver was able to view the target, while under 71% and 49% road lighting intensity, the target was only visible to a driver who could fixate his or her eyes on the target. However, the negative contrast was always caused by the glare from oncoming vehicles.
