Why Traffic Lights Are Red Yellow and Green?
Traffic lights are a ubiquitous part of modern society, providing a critical function in directing the flow of traffic and keeping drivers and pedestrians safe. These lights use a system of colors to indicate when it is safe to proceed, when to slow down, and when to stop completely. The colors used for traffic lights are red, yellow, and green, and each color serves a specific purpose. The history of traffic lights can be traced back to the 19th century when gas lamps were used to control the flow of traffic in cities such as London and Paris. The first electric traffic light was developed in the United States in 1912 by a policeman named Lester Wire. However, it wasn't until the 1920s that the modern system of red, yellow, and green lights became standard. Clear Lens Pedestrian Traffic Light Red is the most prominent color used in traffic lights and is used to indicate that drivers and pedestrians should stop. The reason why red was chosen for this purpose is because it is a highly visible color that can be seen from a distance. In addition, red is often associated with danger, making it an effective way to alert people to potential hazards. When the traffic light is red, it indicates that traffic should come to a complete stop and wait until the light changes. Yellow is the next color used in traffic lights and is used to indicate that the light is about to change from red to green. Yellow is a transitional color that serves as a warning to drivers and pedestrians that they should prepare to stop. This color is also highly visible and easy to spot, making it an effective way to alert people to changes in the traffic signal. Green is the final color used in traffic lights and is used to indicate that drivers and pedestrians should proceed. Green is associated with safety and go, making it an appropriate color to use when it is safe to proceed. When the traffic light is green, it indicates that drivers and pedestrians should proceed with caution and

Mobile Variable Message Signs: Advancing Traffic Management
As cities grow, traffic congestion becomes a major challenge for urban planners and city managers. One way to manage traffic flow is through the use of variable message signs (VMS). These signs are typically mounted on bridges or overpasses, and provide real-time information to motorists about traffic conditions, road closures, and detours. However, with the advent of mobile VMS, traffic management has become even more efficient and effective. What are Mobile Variable Message Signs? Mobile variable message signs (MVMS) are portable, trailer-mounted VMS units that can be easily transported to different locations. These units have a built-in power source and can be remotely programmed to display different messages as needed. MVMS can be deployed in various scenarios, such as construction zones, accident sites, and special events. How are MVMS Beneficial to Traffic Management? MVMS offer several advantages over traditional VMS. Here are some of them: Increased Flexibility One of the main benefits of MVMS is their portability. Since they can be easily transported, they can be quickly deployed to any location where they are needed. This makes them an excellent tool for managing traffic in emergency situations or unexpected events. Reduced Traffic Congestion By providing real-time information to motorists about road conditions, MVMS can help reduce traffic congestion. For example, if there is a lane closure or accident on a major highway, the MVMS can alert drivers to the situation and recommend alternative routes. This can help divert traffic away from the affected area, reducing congestion and improving overall traffic flow. Improved Safety MVMS can also improve safety on the roadways. By providing information about upcoming construction zones, detours, and other potential hazards, they can help drivers make informed decisions and avoid accidents. Cost-effective MVMS are generally more cost-effective than permanent VMS. Since th
