The Effectiveness Of The Dynamic Envelope Pavement Markings

By Helen Thompson


Most of railway related accidents in the globe happen in the highway-railway grade crossing. This occurs as a result of collisions between vehicles and trespassers as the train makes its way through the road. These accidents in most cases lead to death and injuries, and therefore, great care should be taken by drivers as well as other trespassers making their way through these railway crossing zones. For the safety of the road users, the knowledge on the dynamic envelope pavement markings has extremely become important.

The strategy was established to control the number of drivers and motorist who stops on the road tracks of the train. The approach is achieved by painting the entire dynamic envelope with a brightly colored paint. The paints should be very visible and with the ability to reflect headlight for its effectiveness both during the day as well as during the night.

Efforts have as well been made to help define the standards for the installation and the maintenance of traffic control devices. For the implementation of this strategy, the painting is done at the entire area between the two sets of the track. The paint often used is usually yellow in color.

The entire area extends around six feets with a pattern marked with letter X just outside the tracks. The box helps to prevent the road users from crossing to the other side of the track if there is no enough space for him to fit in. The box has always been used to measure the ability to keep the drivers off from entering the crossing only after there is sufficient space on the other side of such track.

These writings are often mounted some distance before and also after the train and road intersection. The use of traffic officers has actually been an effort done to help well reduce the congestion at this way points. They much help in the implementation of the safety measures at these points. These people as well help reduce the challenges encountered at these zones.

In most cases the preemption strategy has been considered more effective in a high way grade crossing. The strategy inculcates the use of a box to help inform drivers whether there is enough space for their vehicles just ahead the crossing zone.

There has been some improved effectiveness of pavements marking around the train passing zones and more preferably within the dynamic envelope. This is the region just adjacent to the tracks at the grade crossing. This positively works to influence the drivers behavior of stopping just ahead of the track. It as well works to minimize the number of vehicles that come to make a stop at these zones.

To sum up all the above information, there is the great need for the road users to understand the effects of the dynamic envelope pavement marking as well as the signals involved in it. It is only by the efficient use of this knowledge that driving behavior, as well as the drivers stopping the behavior, will be coded.
