Working Together to Solve Your Puzzle MARCH 2017 | MassTransitmag.com | Mass Transit | 27 commands to assist travelers — improving the speed of communications as well as providing a safer environment for passengers. Even in non-emergency situations, digital signage can help protect passenger safety. Digital displays can be used for “if you see something, say something” messages or public service announcements on harassment or keeping bags off seats, and are much more likely to draw the eye than static signage: Rich Media Technologies study indicates that digital signage is 63 percent more attention grabbing than static signs. Transit agencies looking to invest in digital signage to boost public safety and security have two main options: liquid crystal displays (LCDs) and light-emitting diode (LED) displays. Both types of displays come at a greater investment than a static sign, but benefi ts like increased viewership and the power to send emergency alerts will outweigh the costs and help transportation offi cials protect passengers. Digital Displays: LED Versus LCD Both LCDs and LED displays can be used for public safety and security messaging, but location and budget will dictate which types of displays are used where. LCD is a more traditional technology that utilizes a transmissive LCD panel and LED backlights, with all video processing and power within a self-contained system. It allows for a lower pixel pitch than its LED counterpart and therefore higher-resolution capabilities for closer viewing distances. While LCD displays come in all diff erent forms and levels, it is important to choose a robust display. Robust displays refer to those with capabilities beyond that of a traditional television. Integrated active cooling for thermal dissipation, full external control, a full metal chassis and a matte fi nish in the panel are all qualities associated with commercial-grade displays. In transportation hubs, there is oft en a fair amount of incident light, so if a display panel does not have a matte fi nish — or is considered high haze — oft entimes this light is refl ected back and can negatively aff ect the image on the screen. High-haze panels scatter incident light off the screen rather than refl ect it, which allows for a more readable display in areas with high ambient light. /…iVœ…iÈœ˜œvÌ…iÃivœÕÀVœ“«>˜ˆiÈÃvœÀÌ…iLi˜iwÌœvÜۈ˜} >œvÞœÕÀÌÀ>˜Ã«œÀÌ>̈œ˜˜ii`ðÀœ“vÕÀi…>LÃÌœÀi«œÜiÀà Ã>ià >˜` i>Ș} Üi V>˜ ÃœÛi ÞœÕÀ «ÀœLi“ Ü…iÌ…iÀ Lˆ} œÀ Ó>° Vœ“«iÌiVœ>V…°Vœ“ÌÀ>˜ÃˆÌÃ>iðVœ“ÃLLÕðVœ“âi«Ã`ÀˆÛi°Vœ“ nää°Îää°ÎÇx£ | nää° 1-°-č For more information, visit www.MassTransitmag.com/10065706 Public transit remains a very safe form of travel, yet transit agencies must stay alert to the potential hazards and investigate new ways to prevent or detect them.
