Most recent update: February 19, 2018 Will the dot adjust a traffic light whose cycle is too long or too short? perhaps. You may communicate with the traffic engineering department of the dot, county, or municipal road maintenance department if you believe that a signal’s cycle is too lengthy or too short. But it’s also possible that they think the cycles are great, thank you. Unless, of course, a lot of other individuals have voiced complaints about the same crossroads than you. The good news is that most municipalities periodically monitor traffic flow at busier intersections, noting that during busy or not-so-busy times of day, traffic backs up beyond normal. Based on these observations, the municipalities can recommend to the traffic engineers that the length of the light signal at a particular intersection appears to be the cause of the excessive back-ups or delays. How does the Department of Transportation determine whether a junction needs a traffic signal installed? Having worked on many private road or street projects with different dots, I’m going to venture an informed estimate since I’ve never worked for the USDOT or any state dot. As previously said, the dot will use pneumatic road tubes to monitor traffic across roads or streets at different areas, such as where it is clear that additional dwellings are being constructed, a school will be erected, or commercial growth is occurring. The municipal road department or the dot commonly installs a traffic signal at a junction if it is seen that there is an increased volume of traffic in that region and that the traffic is becoming too heavy or backed up at stop signs, for example. If the intersection has little traffic, adding 4-way stop signs can cost as little as $1500–2000, but roundabouts can cost as much as $50,000. Unfortunately, I feel that municipal and county road departments are using more and more roundabouts, which impede traffic flow. The majority of municipal road departments are also aware of the locations of schools and shopping malls due to various building permitting procedures. One of the requirements for constructing the shopping mall is typically for the commercial construction company to install new streets, traffic signals, and various traffic control signs or signals, such as electronic crosswalk signs. In what ways do traffic signal standards meet the demands of drivers who are color-blind? Would it be preferable to add forms to the signal indicators so that those with color vision impairments may more easily determine which signal is on? Given the extreme brightness of LED traffic signal lights, those with color-deficient vision, or color blindness, are legally obliged to understand that red is at the top, yellow is in the center, and green is at the bottom of the light. Although we don’t think the present arrangement needs any more forms, you could literally become very wealthy if you wanted to launch a signal production company that could spread the word about this concept and then pressure lawmakers to approve legislation. That’s the modern way of doing things. Give a half-baked concept, get some influential friends, split the earnings with them, and presto! You’re wealthy!
