‘[adrotate group=”1″] Traffic circles, also known as roundabouts or rotaries, are circular intersections that are designed to reduce crashes, injuries, and congestion by eliminating traffic lights and allowing vehicles to flow continuously in one direction. However, traffic circles are not without their drawbacks. In this post, we will explore some of the cons of traffic circles and why they are not always the best solution for traffic management. Confusion and Fear One of the main disadvantages of traffic circles is that they can cause confusion and fear among drivers, especially those who are unfamiliar with them or encounter them infrequently. Traffic circles ,than conventional intersections, such as yielding to the traffic already in the circle, choosing the correct lane, and exiting at the right time. These rules can vary depending on the size, design, and location of the traffic circle, adding to the complexity and uncertainty. Some drivers may not know how to navigate a traffic circle properly, leading to mistakes, hesitation, or aggression. Other drivers may avoid traffic circles altogether, preferring to take longer or less convenient routes. Space and Cost Another disadvantage of traffic circles is that they can take up more space and cost more money than conventional intersections. Traffic circles typically require a larger footprint than traffic lights, which can be a problem in urban areas where space is limited or valuable. Traffic circles may also require additional land acquisition, road widening, or relocation of utilities, which can increase the cost and complexity of the project. Moreover, traffic circles may not be compatible with existing road geometry, traffic patterns, or environmental conditions, requiring additional modifications or adaptations. Safety and Efficiency A third disadvantage of traffic circles is that they may not always improve safety and efficiency as intended. While traffic circles can reduce the severity and frequency of crashes by eliminating right-angle and head-on collisions, they can also increase the risk of rear-end and sideswipe collisions by forcing drivers to merge, change lanes, and exit at high speeds. Furthermore, traffic circles may not be able to handle large volumes of traffic or accommodate large vehicles, such as buses, trucks, or emergency vehicles, resulting in congestion*, delays, or conflicts. Additionally, traffic circles may pose challenges for pedestrians, bicyclists, and visually impaired people, who may have difficulty crossing the road or finding their way around the circle. *I can attest to not handling large volumes of traffic. An intersection I frequently used, (with a stop sign would mean a short stop and go). With the roundabout it took over a half hour to cross that intersection. I was going North, the East-West traffic was so congested because of roundabouts further down the road causing a steady flow of people going East and West to and from work. There was traffic backed up as far as the eye could see. Now you go back to the other roundabouts and you can imagine the North-South traffic was backed up at each one. As if the backup wasn’t bad enough imagine the problems caused by the people backed up. Either trying to cross the street or entering the street we were on, and at the other roundabout traffic circles. Just accidents, ROAD RAGE, etc. I came to the conclusion the real gains were made by the TOW TRUCK operators. I am sure they must have a party everytime a new roundabout is built. (Not really a party, BUT knowing their profits will rise). Conclusion Traffic circles are not a one-size-fits-all solution for traffic management. They have their pros and cons, and their effectiveness depends on various factors, such as the design, location, and context of the traffic circle. Therefore, traffic engineers and planners should carefully evaluate the benefits and drawbacks of traffic circles before implementing them, and consider alternative or complementary measures, such as traffic signals, signs, markings, or education, to enhance the safety and efficiency of traffic circles. ‘[adrotate group=”1″] Views: 135

Roundabouts
I’m sure you are mostly aware of the ROUNDABOUTS, that many areas are putting in to supposedly relieve traffic on some busy roads. When the Interstate system was instituted the brain child for entering and exiting the interstate was a little thing called the clover leaf. Some states still have these accidents waiting to happen. The way it works, for those of you are unaware. The traffic entering the Interstate just happen to use the same lane as people exiting the Interstate. It is sort of hard to explain without seeing it. But try to imagine being on the Interstate and you come to your exit, and must get in an exit lane. But as you are trying to get in the exit lane you have people coming onto the Interstate using that same lane. Confusing, yes it is a miracle more people haven’t been killed. The Roundabouts are the same thing. The ones I have been on have two lanes an inner lane and an outer lane. Where you once had a 4 way stop you now have a 4 way go. If you come to one of these and are going straight you get in one of the two lanes but if you are making a…lets say a normally left turn you would most likely get in the outside lane. If you aren’t turning left but want to turn right or go straight you normally get in the inner lane. But because you have cars coming in the Roundabout from 4 different directions, you could go round several times before you are able to work yourself to the outer lane. Many times I have seen near accidents, and nearly been involved in them, on these Roundabouts. Thank heaven we don’t have any of them in our area, only when we go to the big City. I don’t see how this can help anyone. It is like a monster waiting to devour your car. I personally avoid any roads with these things in them. That means businesses located on these two roads miss any business I may have for them. Roundabouts and Clover leafs are more dangerous than people driving 10 miles over the speed limit, I’m all for banning Roundabouts in the United States. They are already changing many of the clover leafs to a safer system but look how long that has taken. That’s How I See It Views: 121
