<br />3. Color Contrast and Brightness: Set standards for color contrast and brightness levels to <br />ensure optimal visibility and legibility of dynamic signs. <br />4. Integration with Technological Innovations: Create a framework within the Sign Code that <br />accommodates emerging technological innovations in dynamic sign displays. <br /> <br />Community Impact: <br />The proposed amendments are designed to positively impact the community by: <br /> <br />1. Enhancing Communication: Improving the effectiveness of dynamic signs for conveying <br />important information, including traffic updates, safety messages, and community <br />announcements. <br />2. Adapting to Technological Changes: Ensuring that our sign regulations remain adaptable <br />to technological changes, promoting innovation and responsiveness to community needs. <br /> <br />Duration of Display: <br />The typical duration of display for dynamic signs can vary based on the type of information being <br />conveyed, traffic conditions, and local regulations. However, there are general guidelines and best <br />practices that cities and transportation authority’s often follow when determining the duration of <br />content on dynamic signs: <br /> <br />The new brightness and automatic copy limits include an eight-second hold time on images, a <br />brightness limit of 0.3 foot-candles above ambient light for static images, instantaneous transitions <br />from one static display to another, and automatic dimming technology that keeps the brightness <br />within the 0.3 foot-candle limit. <br /> <br />Two methods were examined: lumens and foot-candles. The foot-candle method was chosen <br />because it better corresponded to human vision, is preferred by the sign industry, is more accurate, <br />and more affordable to measure brightness. <br /> <br />It's essential to consider the speed of passing traffic, viewing distances, and the complexity of the <br />information when determining display durations for dynamic signs. Additionally, local regulations <br />and guidelines provided by transportation authorities should be followed to ensure compliance <br />with safety standards and optimal communication effectiveness. Regular reviews and adjustments <br />based on user feedback and evolving traffic patterns can help fine-tune the display duration for <br />dynamic signs over time. <br /> <br />Letter Height: <br />The typical letter height for dynamic signs, including electronic message boards, variable message <br />signs, and other digital displays, is often determined by factors such as the viewing distance, speed <br />of passing traffic, and local regulations. While there is no universally fixed standard, several <br />guidelines and recommendations exist. <br /> <br />As a general rule of thumb, the Federal Highway Administration (FHWA) in the United States <br />suggests a minimum letter height of 6 inches for dynamic signs used on roadways. However, the <br />FHWA also emphasizes the importance of considering the speed of traffic, font characteristics, <br />and the legibility requirements for the specific location.
