I believe that many partners should have the same experience,when driving on the highway at night, we only see car headlights and reflective road signs, basically can not see any other bright light, all is black,around,strange people no sense of security. Why no street lights on the highway ? is it more safe without light?
In fact, it is not the installation of street lights on the highway road except important bridge and tunnel . Now let us analyze why the highway is not installed lights.
Higher safety factor highway
When we driving on the highway road at night,who see pedestrians and non-motorized vehicles coming and going like that in the city streets? No! Because on the highway pedestrians and non-motorized vehicles is allowed to walk or motorcycles, tractors, tricycle and another which can not reach 80 yards under 15 second is not allowed on the highway road too.
Install lights not for vehicle safety and convenience (because car have headlights), but for non-motorized vehicles and pedestrians safe, convenient. The service functions of the different highways and urban roads, urban roads not only vehicle traffic and non-motorized vehicles, pedestrians intensive, so there are street light; highway is outside the urban road connecting city to city, town and country, few non-machine moving vehicles and pedestrians. Thus, the general highway with no street lights.
In addition, the highway pavement is very smooth, no potholes, better road holding, higher safety factor.
Reflective pavement markers meet demand
Install lights on the highway, the driver is more safe or not? The answer is no.
Street lighting is discontinuous and uneven. The driver of the vehicle at high speed, this alternating light and dark cause visual error (illusion), is very dangerous. In addition, it will soon cause eye fatigue. And street lighting of the poor, but also scattered light, make long-distance travel in the driver's glare caused by driving safety risks.
That no street lights, the driver traveling on the highway at night how to do?
When the lack of external lighting, vehicle headlights provide illumination for drivers safer. Since there is no barrier to the car, the high beam at night can start with (this must be very understanding friend to drive). That is why some drivers are like, even when driving on city streets brightly lit open headlight (high beam) reasons (of course, this is bad driving habits).
Vehicle driving at night, perfect road signs and reflective signs fully meet their needs. At night, under intense irradiation car headlights, reflective film will be light on traffic signs, directional reflector to illuminate the road and traffic signs can be clearly reflected to the driver's eyes, enough to complete the function of the direction of the boot.
Cost is not low, management troubles
Our high mileage has more than one hundred thousand kilometers, whole sections of installed street, will cost a small fortune. And random freeway traffic flow line is too strong, for a small amount of car traffic across the board installed street, is bound to cause huge waste of energy. In addition, the provincial highway through the state, each sub-section of the power supply and management is a thorny issue.
To sum up, install lights on the highway is not necessarily scientific, nor energy efficiency. Although highway safety factor is high, parents who still need to be careful driving at night, oh.
