The I-270
The I-270 is the major highway through St Louis. It has been designed to cope with heavy traffic volumes, but there are still times of the day when it can get very congested. This time tends to be in the morning and evening when people are driving to and from work. During this time sections of this highway can get very busy and the traffic will flow very slowly. There is now a solution that has been put into place to try to help prevent this from happening.
Normally when traffic approaches a congested area it will slow down as it approaches and then go very slow or stop when it moves through there. However, if the traffic remains at a constant speed they will move faster through the congested areas and the traffic won’t build up so much. This means that everyone will eventually reach their destination faster because the overall speed is faster than if you drive at a faster speed for a while and then slow right down when you hit heavy traffic.
During busy times the traffic speeds will vary to try and reduce congestion. Therefore you will need to take note of the signs. It may seem that there is no reason to be slowing down, but if you do take notice of the signs you will be less likely to get caught in the busy traffic and get to your destination faster. The speed limits are now an advisory speed. This is because a lot of drivers didn’t like the idea of a variable speed limit as they couldn’t see an immediate change in the way people were driving and they didn’t believe it would cause them to end up going faster. However, the variable speed limit did reduce some of the congestion and help with road traffic accidents. So now the speed has been changed to specify it is advisory. This will warn drivers that there is congestion ahead and it would be a good idea to slow down now. The congestion could be due to road works, land closures, bad weather or stopped traffic for any reason. These are put on ramps and curves as well as other parts of the road. The road signs will tell drivers why the speed limits have been reduced so that they are more likely to slow down.
When there is a speed limit sign you need to make sure that you follow that speed limit or else you can get stopped by the police and receive fines. If there is an advisory speed limit you will need to be careful with your driving but you won’t be fined if you don’t follow it. Be sure that you can tell the difference and if you aren’t sure if it is a set speed limit or an advisory one, then slow down anyway to prevent getting caught out, as the police won’t take not knowing as a reason not to fine you for driving too fast on the highway.
