Warning Tactile Indicators

Warning Tactile Indicators which are also called by the names Hazard Tactiles and Decision Tactiles. They are ideally installed in a raised grid pattern of studs or ‘dots’ to the surface of walking. The main function is to warn blind and vision-impaired pedestrians about any nearby hazard. Warning Indicators have the function the same as a stop sign. It alerts the vision-impaired or blind pedestrians in their line of travel, indicating that they must stop to determine the nature of the hazard before proceeding any further. But it never indicates how the hazard will be.

 

Directional Tactile Indicators

 It is also known by the term Leading Tactiles and comprises of a series of raised bars which are installed to the surface of the walking, oriented in line with the prescribed direction of travel. it safely leads pedestrians along an intended pathway that is free of any obstacles and will often end at a place filled with Warning Tactile Indicators. In cases where other environmental and tactile cues like curb edge or property line are absent and offer insufficient guidance, directional indicators are installed. In open spaces, it offers directional orientation and designates the continuous accessible route which should be taken for avoiding hazards. It also offers a directional orientation to a person who could have deviated from the continuous accessible path for gaining access to a public transport access point, crossing point, or point of entry to a significant public facility like public information center or toilets.
