Easiest way to make traffic flow more freely in all of Florida! Increase the speed limit on I-95!

This solution is fundamentally cost effective & I fully believe it would help traffic flow better & create more revenue for the state.

My idea is to increase the speed limit on I-95 from 55 to 70, and raise the minimum speed to 55.

This solution is fundamentally cost effective & I fully believe it would help traffic flow better & create more revenue for the state; as well as help to avoid costly traffic accidents - making our highways safer!

The solution is super easy & simple but can affect many areas.

Cost - Change speed limit signs is very cost affective.

Flow of traffic - Most jams on I-95 happen because a few slow drivers take up all lanes in parallel or the amount of cars doesn't allow flow. Increasing speed limits allows those who do not want to excede the limit to move faster. This creates more natural flow, opportunity for more cars to access the highway during the same time frame, & can actually be safer. Most other highways [turnpike, I-75, I-595] have higher speed limits & tend not to jam up like I-95.

Accidents - A lot of accidents happen from frustrated drivers trying to constantly switch lanes to get ahead of slow drivers. With the increase in speed this will encourage people to stay in their lanes making traffic safer. Even if there is someone holding up the "fast" left lane, if they are driving at least the speed limit they will be going 70mph under this proposed change.

Revenue - There are two express lanes on I-95. Also with access to the turnpike & express lanes on I-595 connecting to I-95, there is greater opportunity for a faster rate of vehicles in the express lanes. This will increase toll revenue exponentially. The system is already in place & working. Faster speed also gets people connected to the other toll roads quicker.

So the slow people are still going to go slow and the fast people are going to go faster, and by doing this we will have fewer traffic issues? This concept makes my brain hurt.
A Florida Autobahn might be the perfect answer. Think of the tourism draw.

I think that thinking in general makes your brain hurt. Surprised there is something there to feel pain based on your comment.

Hi Evan,

There is research that shows that traffic collisions are more likely where there are high differences in speed, and I think some transportation planners may have increased speed limits on some highways in order to minimize the gap between vehicle speeds and thus minimize collisions that are likely in that scenario. But I am not confident that the traffic congestion on I-95 is caused by a speed limit that is too low. I understand some assertions you are making about how people will be encouraged to drive faster, and people will be encouraged to stay in their lanes. Could you explain or cite what has convinced you of this? It's just the kind of thing that is scary to go with on just gut feeling, because there is also research that distracted driving (texting, eating, etc) is a huge problem that leads to traffic issues but your solution doesn't address that. Know what I mean?

My solution does solve that.

Are people more likely to feel comfortable enough to text or do other things at slower speeds or faster speeds? Common sense would say slower.

About the lane changing, my first hand experience with 14 years of commuting into downtown Miami / South Beach from the Fort Lauderdale area is what I am sourcing. When things slow down a percentage of drivers will start trying to "jump" cars by taking up the given space between two cars in the lane next to them. Often they then hit their breaks causing the chain reaction. Traffic is about flow. Correct the flow & you fix traffic.

I was in Cairo last year & the highways are just as populated if not more. They also squeeze 7 cars into 5 lanes since there is basically no road laws. Traffic pretty much flowed constant because almost all of the drivers drove the same speeds.

Thanks for clearing that up. I understand where you are coming from but personally feel super uncomfortable with leaving assessments like this up to "common sense". Predicting how people will behave is no piece of cake and shouldn't be taken for granted. Relying on your intuition or personal experience to assess how thousands of people behave during millions of trips per year is really risky to the success of your proposal.

If looking at any data on driver behavior for South Florida that might already exist isn't possible, I'd consider implementing a study phase as part of the proposal! Hope this was constructive, and good luck.
