We always tend to criticize the DGT for its collection effort and that its main measure to reduce the number of accidents is the installation of radars on all roads. However, we are glad to see that you also present other interesting solutions that could avoid accidents improved infrastructure. They have presented a battery of measures, among which five stand out for their effectiveness and low cost. In fact, they can already be seen on some highways in the country and will spread in the near future.
smart crossings
It is the most effective measure of all, since it is estimated that it reduces the accident rate by 50%. It consists of installing a smart signals at intersections or dangerous crossroads, especially those on conventional roads. Using sensors, the signal lights up when there is a vehicle that is going to make the crossing maneuver. In this way, the driver who is on the main road can be alert and thus avoid a possible frontal-lateral collisionwhich are the most common in this type of maneuver.
separation of senses
The separation of traffic directions It is a measure that can reduce the accident rate between 38 and 40%. It consists of separating the lanes of a conventional road in various ways so that vehicles traveling in the opposite direction are less likely to suffer a frontal or frontal-lateral collision. It is achieved by increasing the width of the median, installing a physical barrier or a central area framed by two longitudinal lines with a different color or texture. There are also occasions when it is used to reduce the speed of users, by giving the perception that the lane is narrower.
pigmented flooring
The driver has a very normal vision of traffic signals, but if he is mistaken he can make them go unnoticed. Thats why he pigmented pavement could reduce claims by 35% if used in dangerous areas such as a sharp curve or intersection. This measure consists of paint the asphalt a striking shade, normally red, to warn the user that he has to increase his attention in that section. It is also used for other applications such as the approach to crossroads, pedestrian or cyclist crossings and at low speed points.
sound guides
The sound guides They are among the best known on the list and help reduce accidents by 21%. They are those small indentations or bumps on the edges of the road that produce a vibration or sound when the driver hits them with the tires. They are especially useful for alert drivers that they are going to leave the road or may invade the opposite lane, either due to a distraction or due to drowsiness. They can also be used to reinforce continuous lines or prevent encroachment on the hard shoulder.
ditch protection devices
The ditch rescue devices they do not directly prevent an accident, but they reduce their mortality or serious injuries by up to 70%. It consists of a tube system or small structures that give continuity to the longitudinal drainage, thus reducing the depth of the ditch. In this way, if a vehicle leaves the road, the impact is not as strong or its trajectory can even be redirected. It can also mitigate a motorcycle accident.
